ASTM A36 Mild/Low Carbon Steel plate

ASTM A36 steel Introduction:
ASTM A36 steel is one of the popular and widely used carbon structural steels which is mild and hot rolled. ASTM A36 carbon steel has ultimate welding properties and it is perfectly suitable for punching, grinding, drilling, tapping and machining processes.

Yield strength of ASTM A36 is less than that of cold roll C1018, thus enabling ASTM A36 to bend more readily than C1018. Normally, larger diameters in ASTM A36 are not produced since C1018 hot roll rounds are used.
