ASTM A663/A663M Grade 65 Introduce
ASTM A663/A663M Grade 65 steel is a low-carbon alloy steel designed for a variety of applications. The 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. This steel has a few important mechanical properties that should be considered when determining its suitability for use in a given application. These properties include tensile strength, yield strength, elongation, ductility and impact strength.
Smelting temperature:1295°C - 1371°C
Application:Mechanical properties of commercial grade carbon steel rods
