Worldwide equivalents of grade A36 (USA: AISI, ASTM, UNS)

ASTM A36 is a widely used carbon structural steel, which follows the standard ASTM A36/A36M-03a. The following is detailed information about ASTM A36:

1 Chemical composition carbon (C): ≤ 0.25% silicon (Si): ≤ 0.40% manganese (Mn): 0.80%~1.20% phosphorus (P): ≤ 0.04% sulfur (S): ≤ 0.05% copper (Cu): When copper containing steel is specified, Cu≥0.20%， But usually ≤ 0.2% Mechanical properties yield strength: ≥ 250MPa tensile strength: 400MPa~550MPa elongation at break: ≥ 20%

3 Application areas: Construction industry: Manufacturing steel structure frames, support beams, steel plates, and steel pipes. Mechanical manufacturing industry: Manufacturing various mechanical components such as bearings, gears, bolts, etc. Ship and bridge construction: Building ships and bridges, as well as manufacturing oil tanks and pipelines, etc Delivery Status Hot Rolling Delivery Control Rolling Delivery (Control Rolling) Heat Treatment Delivery (Normalization) Normalization Rolling Delivery Other delivery statuses (such as cutting and processing according to customer drawings, etc.)
