Do you know the thickness range of BBN Steel's hydrogen sulfide resistant steel plate? The a516 grade 70 section product thickness is between 8-180mm. Q345RHIC steel and Q345RR-HIC test environment: A solution HIC steel (HIC-A) and B solution HIC steel (HIC-B) Q345RHIC and Q345RR-HIC test items: tensile, bending, thickness direction properties, grain size, Brinell Hardness, ultrasonic flaw detection, HIC test, impact test, high temperature tensile test, SSCC test, melting analysis, finished product analysis.

EN 10025-2 steel includes S235 steel (S235JR, S235J0, S235J2), S275 steel (S275JR, S275J0, S275J2), S355 steel (S355JR, S355J0, S355J2, S355K2), S450 steel (S450J0). According to EN 10025-2, the thickness of S450J0 plate is within 3-150mm. The a516 grade 70 section, S235 steel, S275 steel and S355 steel plate thickness is ≤250mm. However, the S235J2, S275J2, S355J2 and S355K2 plates limitation is ≤400mm.

The deoxidization process of Q345R boiler vessel plate if the type and amount of deoxidizer are controlled to make a certain amount of oxygen remain in the a516 grade 70 section steel, when sufficient amount of strong oxidant is added to make the steel deoxidize well, the co bubble will escape during the solidification process and generate boiling phenomenon, no co bubble will be generated during the solidification of the a516 grade 70 section steel, the steel used for the pressure vessel of the killed steel is called the killed steel, this kind of steel is called the boiling steel.
