ASTM A36 steel

ASTM A36 is the most commonly used mild and hot-rolled steel. It has excellent welding properties and is suitable for grinding, punching, tapping, drilling 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.
ASTM A36 is usually available in the following forms:

• Rectangle bar
• Square bar
• Circular rod
• Steel shapes such as channels, angles, H-beams and I-beams.

A36 Steel Chemical Composition:
C  0.25 – 0.29
Si <0.280
Mn < 1.03
P < 0.040
S < 0.050
A36 Weldability
ASTM A36 steel is easy to weld using any type of welding methods, and the welds and joints so formed are of excellent quality.
A36 Heat Treatment
Any standard carburizing and hardening methods of AISI 1018 steel is suitable for ASTM A36.
ASTM A36 is subjected to the following processes:

• 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)

A36 Applications
ASTM A36 steel has the following applications:

• It is used in bolted, riveted or welded construction of bridges, buildings and oil rigs.
• It is used in forming tanks, bins, bearing plates, fixtures, rings, templates, jigs, sprockets, cams, gears, base plates, forgings, ornamental works, stakes, brackets, automotive and agricultural equipment, frames, machinery parts.
• It is used for various parts obtained by flame cutting such as in parking garages, walkways, boat landing ramps and trenches.
