If you’ve ever stood inside a well-running electric motor, wind turbine generator, or the compressor that keeps your AC unit cool in the summer, you’ve actually been around non oriented silicon steel (NO硅钢？No, wait—non oriented silicon steel, or NO steel for short). I’m a NO steel supplier, and over the past few years, the question I get asked most by new and regular clients alike is: “What’s the market demand for this stuff, anyway?” Non Oriented Silicon Steel
Let’s cut the formal jargon, because I’ve sat in enough late-night meetings with motor design engineers and procurement managers to know that most folks don’t care about IEEE papers or IEC standards unless it’s directly tied to their bottom line. Let’s start with the basics: NO steel isn’t the shiny, grain-oriented stuff used in power transformers—this is the softer, more flexible alloy that turns electrical energy into mechanical motion, and vice versa. It’s got silicon mixed in to reduce energy waste (no one wants a motor that turns 10% of its energy into heat, right?), and it’s called “non oriented” because its magnetic properties work equally well in all directions, perfect for the chaotic, spinning fields inside motors and generators.
Now, back to demand. Over the last decade, I’ve watched that demand ebb and flow, but the big drivers right now aren’t just random—they’re tied to two huge global shifts: electrification and energy efficiency regulations. Let’s break that down, starting with electrification because it’s non-negotiable at this point.
Take EVs, for example. Ten years ago, most passenger cars ran on gas, and the ones that had electric motors were tiny, low-power things for windshield wipers. Today? A single EV has 10 to 15 different electric motors—for the traction system that moves the car, the power steering, the air conditioning, the water pump, even the side mirrors. Each of those motors needs NO steel, and not just any NO steel: it has to be efficient enough to not eat into the car’s range. I remember three years ago, when we got our first big EV client order, we had to crank out high-grade NO steel with lower core loss—meaning less energy wasted as heat, which directly translates to more miles per charge. That order was 20% bigger than our entire annual NO steel output from five years prior. And it’s not just passenger EVs; commercial EVs like delivery vans, heavy-duty trucks, and even electric buses are exploding. The International Energy Agency (IEA) says that by 2030, we’ll have 145 million EVs on the road worldwide, up from around 26 million in 2021. Multiply that by the average 10 motors per car, and that’s a lot of NO steel demand. Even if half of that is grain oriented for transformers, the other half? NO steel.
Next, energy efficiency regulations. Governments aren’t messing around here anymore. The EU’s Eco Design Directive, the US Department of Energy’s new motor efficiency standards, and even rules in emerging markets like India and Brazil are pushing manufacturers to build motors that are way more efficient than they were just a few years ago. Ten years ago, a standard induction motor might have had an efficiency rating of 85%; today, the minimum for most industrial applications is 92%, and many manufacturers are targeting 95% or higher. How do you get that? The main upgrade is switching from low-grade NO steel to higher silicon content NO steel, which cuts down on magnetic waste. When those regulations went into effect in the EU in 2021, I watched our European client base grow by 35% in a single year. Small motor manufacturers that used to source cheap steel from overseas suddenly had to shift to more efficient domestic suppliers, and that’s where we came in. Even industrial pump and compressor manufacturers, who’ve been using the same motor design for decades, are now retooling to use better NO steel just to meet the new rules. That’s not a one-time spike—it’s ongoing, because regulations get stricter every few years, not looser.
But wait, it’s not all sunshine and high grades. There are parts of the market that are more volatile, and that’s where I’ve had to adjust as a supplier. For example, the HVAC and appliance sector. A lot of small appliance motors—like those in blenders, dishwashers, or refrigerators—use lower-grade NO steel. When the global supply chain issues hit in 2020 and 2021, demand for these lower-grade steels dropped because appliance manufacturers couldn’t get their hands on plastic and electronics components. Now that supply chains are stabilizing, that demand is bouncing back, but it’s not growing as fast as the EV or industrial motor sectors. Another wild card: renewable energy. Wind turbines use huge generators that rely on large quantities of NO steel. When wind projects get funded, we get big orders, but when there’s a lull in policy support for renewables, that demand slows down. We saw that in the US a couple years ago when the wind production tax credit was temporarily extended, leading to a 40% jump in turbine generator orders for us. It’s a cyclical part of the business, but right now, the overall trend in renewables is up, so that’s a steady long-term demand.
Now, let’s talk about the other side of the coin—what’s holding demand back, because it’s not just all growth. First, there’s the rise of brushless DC motors vs. traditional induction motors. Wait, I know that sounds like tech jargon, but here’s the thing: brushless motors use permanent magnets instead of relying on NO steel for a lot of their magnetic function. That’s cut into demand a little for lower-power applications, like small drones or some home appliances. But here’s the catch: even brushless motors still need some NO steel, and for high-power applications like EV traction motors, induction motors are still more efficient and cost-effective at scale. So it’s a small headwind, not a stop sign. Another factor: raw material costs. NO steel is mostly iron, with silicon, so when iron ore prices spike, like they did in 2022, motor manufacturers hold off on ordering more steel because they’re trying to cut costs. We had a three-week lull in orders that year, which was weird because usually our backlog is full for months. But that’s short-term, and once iron prices stabilize, demand bounces back. The last thing is counterfeit or low-quality steel from unregulated sources. A lot of small, fly-by-night suppliers in places like Southeast Asia sell NO steel that doesn’t meet efficiency standards, so manufacturers will buy it to save a few bucks, but it ends up costing them more in energy bills over time. That’s why a lot of the bigger, more reputable motor manufacturers are willing to pay a little more for our certified NO steel—they know it saves them money in the long run, and keeps their products compliant.
As a supplier, I’ve had to adapt to this demand shift over the past five years. When EV demand started taking off in 2019, we didn’t have the equipment to make high-grade NO steel with the tight tolerances EV manufacturers need. So we invested in a new production line, hired a team of metallurgists who specialize in NO steel for e-motors, and now we can turn around custom orders in half the time we used to. That’s the thing about this market: it’s not static. Clients don’t just want the same standard 0.5mm thick steel forever—they want thinner, more efficient steel that fits into smaller motors, or steel that works at higher temperatures for heavy-duty applications. Last year, we worked with an EV startup that wanted NO steel that could handle 180 degrees Celsius, which is 20 degrees higher than the standard. We tested three different silicon compositions, adjusted the annealing process, and delivered the batch two weeks ahead of their deadline. That’s the kind of thing that keeps demand high—clients don’t just need a supplier, they need a partner who can adapt to their specific needs.
So where is this market going next? I don’t have a crystal ball, but here’s what I’m seeing from my end. By 2027, global demand for NO steel is projected to hit around 25 million tons, up from around 18 million tons in 2023, according to recent industry reports. The biggest chunk of that growth is going to come from EVs and industrial motor efficiency. Even as some applications shift to brushless motors, the overall demand for electricity is going up—more data centers, more smart buildings, more industrial automation—all of which rely on electric motors, and all of which need NO steel. Another big one: India and Southeast Asia. Those regions are skipping the old, inefficient motor models and going straight to the high-efficiency versions, so their demand is growing faster than anywhere else. We just opened a small distribution hub in Singapore last year to handle that demand, and it’s already our fastest-growing region.
If you’re a procurement manager, motor designer, or manufacturer who’s been wondering if now’s the time to lock in NO steel supply, let’s be real: the demand is only going up. There’s no way around it. Regulations are tightening, electrification is here to stay, and no one’s going back to the old, inefficient motor designs. The only real question is whether you’re working with a supplier who can keep up with that demand, whether you need standard-grade steel for an appliance line, high-efficiency steel for EVs, or custom steel for a wind turbine generator. We’re here to help—we’ve got 15 years of NO steel production under our belt, we work with clients across 20 countries, and we can adjust to whatever volume or grade you need. If you’re looking to lock in supply, get a quote for a custom order, or just chat through what grade works best for your application, feel free to reach out. I’m happy to walk through our production processes, our efficiency certifications, or anything else you need.
At the end of the day, non oriented silicon steel is the unsung hero of modern electrification. You don’t see it in your car or your fridge, but it’s the reason those things work efficiently, save energy, and meet global standards. As a supplier, I’m not just selling metal sheets— I’m helping clients build better, more efficient products that will last for years. And right now, that’s a market with way more growth ahead than roadblocks.
