M310-M800 Non-Grain Oriented Silicon Electrical Steel
In the modern industrial landscape, 50w800 CRNGO (Cold Rolled Non-Grain Oriented) silicon steel has emerged as a cornerstone material for electrical engineering. As global economies pivot toward carbon neutrality, the demand for high-efficiency electrical steel has skyrocketed. 50w800, characterized by its 0.5mm thickness and maximum core loss of 8.00 W/kg, represents the optimal balance between performance and cost-effectiveness for mass-market electrical appliances.
From the industrial hubs of the European Union to the rapidly expanding manufacturing sectors in Southeast Asia, 50w800 is the preferred grade for small to medium-sized rotating machines. The global CRNGO market is currently experiencing a CAGR of over 6.5%, driven primarily by the transition to high-efficiency motors (IE3 and IE4 standards) and the relentless growth of the electric vehicle (EV) auxiliary motor sector.
Global buyers are shifting toward manufacturers who offer transparent, real-time supply chain tracking and digital quality certifications. At Step Million Steel, we integrate AI-driven logistics to ensure timely delivery.
As energy regulations tighten (such as ErP directives), the industry is moving toward thinner gauges and lower loss values. Our 50w800 grade consistently outperforms standard market specs in magnetic induction.
Enterprises are seeking "China + 1" strategies, yet China remains the authoritative hub for CRNGO due to its massive raw material integration and specialized processing facilities like ours.
STEP MILLION STEEL SUPPLY CHINA CO., LTD. founded in 2010, is a leading steel material supplier and manufacturer in China. Our production facilities cover over 66,700 square meters, employing more than 300 professionals, including 20 R&D engineers with over 10 years of experience.
We operate eight High Frequency welded lines, with a monthly output of 100,000 tons. Our strategic cooperation with giants like Baowu Iron and Steel Group and Shougang Group allows us to provide premium 50w800 CRNGO at competitive wholesale prices. We serve prestigious clients like LG Electronics and Xizi United, exporting to nearly 100 countries across Middle & South America, Southeast Asia, and Africa.

The 50w800 grade is a cold-rolled non-grain-oriented silicon steel with a silicon content typically between 0.5% and 3.0%. The "50" indicates a nominal thickness of 0.50mm, while "800" guarantees that the iron loss is no higher than 8.00 W/kg at a frequency of 50Hz and a magnetic induction of 1.5T.
| Grade | Thickness (mm) | Max Core Loss (W/kg) @1.5T/50Hz | Min Magnetic Induction (T) @2500A/m | Lamination Factor (%) |
|---|---|---|---|---|
| 50W800 / M800-50A | 0.50 | ≤ 8.00 | ≥ 1.60 | ≥ 97 |
| 50W600 / M600-50A | 0.50 | ≤ 6.00 | ≥ 1.62 | ≥ 97 |
| 50W470 / M470-50A | 0.50 | ≤ 4.70 | ≥ 1.64 | ≥ 97 |
