A516Gr.65material is a carbon steel plate for medium and low temperature pressure vessels, which implements the ASTM A516 standard of the American Standard. The S900MC construction machinery steel) product minimum thickness that can be provided is 8mm and the width is 1500~4000mm. It has sufficient strength and toughness, good welding performance and hot and cold processing performance. A516Gr.65 steel plate can be used to manufacture pressure vessel steel for petrochemical, gas separation and gas storage, oil storage tank and transportation equipment.

Main characteristics of 12Cr1MoV Steel: compared with 12CrMoV steel, 12Cr1MoV steel has higher oxidation resistance and thermal strength. The creep limit of 12Cr1MoV steel is very close to the endurance strength value, and it has high plasticity under the condition of endurance tension; the processability and weldability of 12Cr1MoV steel are good, but it needs to be preheated to 300 ℃ before welding, and stress removal treatment after welding. 12Cr1MoV steel is widely used in Superheater, header and main steam pipe of high pressure, ultra-high pressure and subcritical utility boiler.

The alloying principle of low alloy high strength steel plate mainly uses solid volume strengthening, fine grain strengthening and precipitation strengthening produced by alloy elements to improve the strength of low alloy high strength steel plate, S900MC construction machinery steel. At the same time, the effect of fine grain strengthening on the reduction of ductile brittle transition temperature of low alloy high strength steel platel is used to offset the adverse effect of carbon nitride precipitation strengthening on the rise of ductile brittle transition temperature of steel, so that low alloy high strength steel plate can obtain high strength while maintaining good low temperature performance.
