What is the difference between a516 grade 70 flange steel and mild steel?

Standing at a new historical starting point, we adapt to the requirements of supply side structural reform, adhere to the overall strategy of "innovation driven, quality leading, a516 grade 70 flange quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the a516 grade 70 flange International leading steel materials supplier.

SA387 Gr.12 Cl.2 steel data is suitable for the essence and gas treatment in hydrogenation reaction and conversion equipment at high temperature. It is a chrome molybdenum carbon alloy steel for use in weldable pressure vessels and industrial boilers. The maximum thickness of the steel plate can reach 250mm. According to different a516 grade 70 flange thickness and impact requirements, the delivery situation of SA387 Gr.12cl.2 steel plate is: normalizing and tempering or normalizing and rapid cooling and tempering.

Heat treatment advantages of a516 grade 70 flange, SA516 Gr 70 pressure vessel steel:
1) SA516 Gr 70 pressure vessel steel quenching: The hardness of SA516 Gr 70 pressure vessel steel is increased, but the toughness is decreased.
2) SA516 Gr 70 pressure vessel steel normalizing: Improve strength and toughness.
3) SA516 Gr 70 pressure vessel steel annealing: Eliminate quenching effect, eliminate stress, uniform composition.
4) SA516 Gr 70 pressure vessel steel tempering: Uniform composition, slightly reduce hardness, greatly improve toughness.

Sulfur is a very harmful element in {keyword steel. The presence of sulfur will increase the hot brittleness of steel, reduce the various mechanical properties of {keyword steel, and reduce the weldability, impact toughness, fatigue resistance and corrosion resistance of steel.
