ASTM A36 steel plate is the most commonly used mild and hot-rolled steel. ASTM A36 steel plate 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.
A36 steel tensile strength can be known by following tables:
Mechanical Properties
Mechanical Properties | Metric | Imperial |
Tensile Strength, Ultimate | 400 - 550 MPa | 58000 - 79800 psi |
Tensile Strength, Yield | 250 MPa | 36300 psi |
Elongation at Break (in 200 mm) | 20.0 % | 20.0 % |
Elongation at Break (in 50 mm) | 23.0 % | 23.0 % |
Modulus of Elasticity | 200 GPa | 29000 ksi |
Bulk Modulus (typical for steel) | 140 GPa | 20300 ksi |
Poissons Ratio | 0.260 | 0.260 |
Shear Modulus | 79.3 GPa | 11500 ksi |
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.
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.
