5. Mechanical Property:

Machining	The machinability rate of ASTM A36 is estimated to be 72%, and the average surface cutting feed of ASTM A36 is 120 ft/min. Machining of ASTM A36 steel is not as easy as that of AISI 1018 steel.
Welding	ASTM A36 steel is easy to weld using any type of welding method, and the welds and joints so formed are of excellent quality.
Heat Treatment	Normalizing at 899°C - 954°C (1650°F-1750°F) Annealing at 843°C - 871°C(1550°F-1600°F) Stress-relieving at 677°C - 927°C(1250°F-1700°F) Carburizing at 899°C - 927°C (1650°F-1700°F) Hardening at 788°C - 816°C(1450°F-1500°F)
