A573 grade 70 steel sheet,Q690E material has high strength, good fatigue resistance; high toughness and low brittle transition temperature; good cold forming performance and welding performance. In addition, Q690 high strength steel plate and sheet has good corrosion resistance and certain wear resistance. High strength, especially in the normalizing or normalizing plus tempering state has a higher comprehensive mechanical properties.
A573 grade 70 steel sheet,API 5CT N80 casing pipe is important equipment for oil drilling . API 5CT N80 casing pipe main application is to support the sidewall of the oil well during drilling. API 5CT N80 oil casing pipe plays an important role to guarantee the normal operation of the whole well drilling work.
Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.A573 grade 70 steel sheet
