Manganese steel vs carbon plate
Manganese steel and ordinary steel belong to carbon structural steel and low alloy structural steel. The difference between manganese steel and hardness of Q295NH is different in compressive strength, strength and main purpose. In terms of compressive strength, the compressive strength of manganese steel is higher than that of ordinary steel plate. In terms of strength, the strength of manganese steel is also higher than that of carbon steel, and in terms of application, manganese steel plates have more prominent advantages due to the advantages of materials, so the application areas are more common."

A516 Gr65 steel is a carbon steel plate for medium and low temperature pressure vessels, which implements the ASTM A516 standard. A516 Gr65 plate has the following characteristics: good impact resistance, small temperature deformation, good welding performance, good fatigue resistance, good anti-layered cracking performance, micro-alloying, high purity, low carbon equivalent, strong resistance to sulfur and hydrogen. Our hardness of Q295NH pressure vessel plate has good dimensional tolerance and surface quality.

The alloying principle of low alloy high strength steel is mainly to improve the strength of steel by solid volume strengthening, fine grain strengthening and precipitation strengthening produced by alloy elements. At the same time, the effect of reducing the ductile brittle transition temperature of steel by fine grain strengthening is used to counteract the adverse effect of carbon nitride precipitation strengthening on the rise of ductile brittle transition temperature of steel, so that the hardness of Q295NH, low alloy high strength steel can obtain high strength while maintaining good low temperature performance.

hardness of Q295NH, HP265 steel with the thickness range is 1.2-12mm. HP265 steel’s mechanical properties is include the yield strength more than 265MPa, tensile strength is 410-520MPa. The chemical composition of HP265 steel is C element content is 0.18, the Si element content is 0.10, the Mn element content is 0.80, the P element content is 0.025% max, the S element content is 0.015% max.
