ASTM A686 Type W1 Grade C Introduce
ASTM A686 Type W1 Grade C steel is a highly versatile and reliable steel that is suitable for a range of industrial and engineering applications. Not only does it have excellent strength, hardness, and ductility properties, but it also has excellent fatigue resistance. It is commonly used in industrial and engineering applications, thanks to its combination of strength, ductility, and machinability, as well as its stability under extreme temperatures. Its high strength and low cost has made it a popular choice in many manufacturing processes, particularly for parts that must withstand harsh working environments or those that require a particular degree of flexibility and strength.
Smelting temperature:1522°C - 1578°C
