ASTM A663/A663M Grade 60 Introduce
ASTM A663/A663M Grade 60 steel is an alloy steel used in a variety of applications, including automotive, aerospace and industrial components. The steel is often referred to as a "low carbon alloy" steel and is composed of iron and 0.3-0.5% carbon, as well as a variety of other elements depending on the application. This steel is known for its low levels of strength, both in terms of tensile and yield strength, and is often used in applications where a stronger steel is not necessary.
Smelting temperature:1344°C - 1619°C
