ASTM A36 is a structural quality mild steel. A36 carbon steel’s strength, formability, and excellent welding properties make it suitable for a large variety of applications, including welding, fabricating, and bending.
ASTM A36 is an easy steel to machine, fabricate, and weld. A36 is suitable for grinding, tapping, drilling, punching, and machining processes.
A36 Steel Chemical Composition:
| Carbon | 0.25-0.29% |
| Manganese | 0.80-1.2% |
| Phosphorus | 0.03-0.04% |
| Sulfur | 0.03-0.05% |
| Silicon | 0.4% max |
| Copper | 0.2% |
A36 Steel Mechanical Property:
| Tensile Strength ksi | 50-80 |
| Yield 2% Offset ksi | 36 |
ASTM A36 steel Application:
ASTM A36 is typically used in machinery parts, structural applications, buildings, bridges, automotive, railroad tracks, oil rigs, tanks, agricultural equipment, stakes, gears, forgings, base plates, and more.
HEAT TREATMENT OF A36 STEEL:
It is not advisable to heat treat A36 steel because it is low carbon, but there are other ways of treating A36 that won’t cause damage to the steel.
