ASTM A600 T4 Introduce
ASTM A600 T4 steel is a type of high strength, alloyed steel that has been used for various engineering and industrial applications since the mid 20th century. It is a versatile material that is both light and strong, while steel with this name may often be referred to as a "general purpose steel" because of its wide range of uses, ASTM A600 T4 steel is actually a specific grade of steel, with specific chemical properties and specifications.
Smelting temperature:1763°C - 1666°C
