AGC technology to control thickness of S690 material

A387Gr91Cl2 pressure vessel plate is equivalent to the Chinese grade 10Cr9Mo1VNbN steel. S690 material, A387Gr91Cl2 alloy steel plate not only has high oxidation resistance and high temperature steam corrosion resistance, but also has good impact toughness and high and stable durable plasticity and thermal strength performance. When the use temperature is lower than 620 ℃, its allowable stress is higher than that of austenitic stainless steel, S690 material.

Oxygen is a harmful element in S690 material steel. With the increase of oxygen content, the strength of S690 material steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of S690 material steel.

S355NC steel offers excellent bending, flanging, cold-bordering and folding S690 material properties in both longitudinal and transverse direction. The bending radii specified below should be observed as minimum values.

Provide special product requirements to meet the personalized needs of customers. The S690 material company arranges production and shipment strictly according to the contract, and guarantees to supply goods according to the time agreed in the contract. Provide professional consultation: we guarantee to answer any professional and S690 material technical questions raised by users within 1 hour; provide detailed information.
