Using the state of the organization for the fine grain ferrite pearlite, strength than ordinary carbon structural steel Q235 about 20% ~ 30%, high atmospheric corrosion resistance of 20% ~ 38%.
The fine ferrite and pearlite were obtained in the meantime and all kinds of properties can meet the request of national standard.
同时可以获得细小的铁素体和珠光体组织，各项指标满足国家标准的要求。

Adding different alloy combination of re, copper and titanium, then through gestation and nodulizing disposal, we got the fine texture of ferrite pearlite and spheroidal graphite.
