Product Description

Hot Rolled Carbon Steel Round Bar A36/Q235/SS400/S235JR

ASTM A36  is a low carbon steel that exhibits good strength coupled with formability. It is easy to machine and fabricate and can be securely welded. A36 is a common structural steel that can be galvanized to provide increased corrosion resistance.

Equivalent grades of steel ASTM A36(Only for reference):

EU	USA	England	Japan	China	Russia

Chemical Composition for A36 (%)

C	Si	Mn	P	S	Cu
0.25-0.29	0.28	1.03	0.04	0.05	0.2

 

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 methods, 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)
