PRODUCT
Tianjin BRISK STEEL focus on produce and supply hollow section and steel pipe
Standard Scope
This specification covers steel shapes, plates, and bars intended for riveted, bolted, or welded construction in bridges, buildings, and general structural applicationsASTM International
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.
Chemical Composition (Max %, Heat Analysis)
| Element | Carbon (C) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) | Silicon (Si) |
| % | ≤ 0.26 | 0.80 - 1.20 | ≤ 0.040 | ≤ 0.050 | ≤ 0.40 |
- Key Trait: Low carbon content ensures superior weldability and ductility.
Mechanical Properties (Typical for thickness ≤ 203 mm [8 in])
| Yield Strength | Tensile Strength | Elongation |
| 250 MPa (36,000 psi) | 400 - 550 MPa (58,000 - 80,000 psi) | ≥ 20% (in 50 mm gauge) |
- Note: For plates thicker than 203 mm, yield strength is reduced to 220 MPa (32,000 psi).
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
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)
