Note: Equivalent grades match in general strength level and weldability, yet minor differences exist in specification details, tolerances and test requirements. For critical or long-cycle projects, please verify detailed project specifications before cross-standard replacement.
03Chemical Composition
Strictly controlled low-carbon chemistry ensures consistent machining performance and structural stability for general building and mechanical projects.
Chemical Element
Content Specification
Carbon (C)
0.25 – 0.29%
Manganese (Mn)

Silicon (Si)
0.28%
Phosphorous (P)
0.04%
Sulfur (S)
0.05%
Copper (Cu)
0.20%
Iron (Fe)
98.00%
Note: ASTM A36 contains no chromium or nickel elements and therefore has no natural atmospheric corrosion resistance. For outdoor or humid environment applications, surface painting, plating or other anti-rust treatments are required to extend service life.
