Grade of cold rolled coil

1, Chinese grade Q195, Q215, Q235, Q275 -- Q -- ordinary carbon structural steel yield point 

(limit) code, it is "bend" the first Chinese pinyin letter of the case; 

195, 215, 235, 255, 275 -- indicate their yield point (limit) values respectively, in MPa (N/mm2); 

Because the strength, plasticity, toughness, weldability and other comprehensive mechanical 

properties of Q235 steel in ordinary carbon structural steel is the best, 

can better meet the requirements of general use, so the application range is very wide.

2. SPCC of Japan -- S-Steel, P-plate, C-cold, the fourth C-Common.
