What are the main standards of carbon structural steel

Carbon structural steel is widely used. The main strengthening elements are C and Mn. The impurity of S and P in steel is less than 0.050%. This kind of steel is generally used directly without heat treatment, and is mostly rolled into plate (strip), profile (I beam, channel steel, angle steel, etc.), special section, wire rod, H-beam, welded pipe, etc., which belongs to engineering steel and it is the main steel for construction.

The basic standard of carbon structural steel is: GB / T 700, the relevant plate and strip standards are: GB / T 912, GB / T 3274, GB 11253, GB / T 716, GB / T 3524, etc.; the relevant pipe standards are: GB / T 3091, GB 3094, GB 13792, GB 13793, YB / T 171, etc. Foreign standards similar to GB are: ASTM A6, ASTM A109, ASTM A283, ASTM A539, ASTM A822; JIS G 3101, JIS G 3136, JIS G 3131, JIS G 3472; EN 10025, DIN 17100, BS 970, EN 10210, EN 10305; ISO 4955, ISO 3573, ISO 3574, ISO 6316, ISO 6317, ISO 630, etc.
