ASTM A675/A675M Grade 515L Introduce
ASTM A675/A675M Grade 515L is an alloy steel that consists of a combination of various elements such as chromium, manganese, vanadium, and others. Its compositional make-up makes it particularly strong and ductile, which makes it an ideal choice for a variety of applications. Firstly, the steel has an excellent strength due to its compositional make-up, as well as its formability, machinability, and weldability. Additionally, it has low thermal conductivity, good thermal stability, and is relatively resistant to corrosion and wear.
Smelting temperature:1558°C - 1967°C
