Chromium Steel Grades by Country
Chromium steel is a core raw material for the production of precision machinery, bearing steel balls and industrial parts. With its high hardness, excellent wear resistance and outstanding fatigue resistance, it is widely used in global manufacturing. In the process of international trade, raw material procurement and product export, different countries have significantly different grade names for the same type of chromium steel, which is likely to cause procurement confusion, material mismatch and other problems. Updated with the latest national steel standards in 2026, this article popularizes the corresponding grades of chromium steel in different countries, listed directly in the form of "Country: Grade", providing clear and intuitive reference for industry practitioners to promote the efficient development of procurement, quality inspection and foreign trade work.
This popular science focuses on high-carbon chromium steel, which is the most commonly used in industrial and bearing steel ball production. As the preferred material for manufacturing high-precision steel balls and bearing rolling elements, this type of chromium steel is the most widely used in the world. The corresponding grades of chromium steel in 8 countries are listed directly below in the form of "Country: Grade", with no accumulation of complex terms, only clear results are presented for practitioners to quickly check and directly apply: China: GCr15, United States: 52100, Germany: 100Cr6 (Material No. 1.3505), Japan: SUJ2, France: 100C6, United Kingdom: 534A99, Italy: 100Cr6, Russia: ЩХ15.
