JIS G7401 X3Cr17E Introduce
JIS G7401 X3Cr17E steel is an advanced material designed for use in industrial and manufacturing applications. It is composed primarily of iron, with a small quantity of manganese, chromium, and carbon, and is usually available in both hot-rolled and cold-rolled forms. Its primary advantages are its strength and durability, as well as its resistance to corrosion. Its properties are well-suited for use in the automotive industry and other industries that require parts with a high level of strength, wear resistance and corrosion resistance. This makes it an ideal choice for manufacturers and engineers when designing products that need to hold up over time.
Smelting temperature:1637°C - 1759°C
Application:Cold heading and cold extrusion steel
