ASTM A600 AISI M-44 Introduce
The composition of ASTM A600 AISI M-44 comprises of elements in substaintial quantities which include carbon, nickel, chromium, molybdenum, phosphorous, manganese and silicon, among a few others. Due to this combination of elements, it imparts excellent strength and hardness. Further, it is easily weldable and best suited to heavy forming, heat treating, broaching and machining operations.
Smelting temperature:1244°C - 1111°C
Application:Tool Steel High Speed
