GB/T 1299 Cr12Mo1V1 Introduce
Manganese and silicon both play a role in strengthening the GB/T 1299 Cr12Mo1V1 steel alloy. They both contribute to improved tensile strength, with manganese being slightly more effective. They also help reduce the amount of carbon in the steel, and silicon plays a role in reducing the risk of brittleness in the steel.
Smelting temperature:1123°C - 1734°C
Application:Alloy tool steel
