Is it reasonable for 09CuPCrNi-B steel elements quenching to get martensite

42Cr2Mo steel is an ultra-high strength steel. The steel has high strength and toughness, good hardenability, no obvious temper brittleness, and small deformation during quenching. After quenching and tempering, 42Cr2Mo alloy has a higher fatigue limit and resistance to multiple impacts. Good impact toughness at low temperature, high creep strength and enduring strength at high temperature. The steel 09CUPCRNI-B steel elements usually adopts surface quenching after quenching and tempering as the heat treatment plan.

Shipbuilding steel plates have always been the key products of our company, and it is sold well in many countries and regions around the world. The thinnest certifiable thickness of our shipbuilding steel plates is up to 3mm. We cooperate with classification societies to certify the shipbuilding steel 09CUPCRNI-B steel elements and issue EN10204 3.2 material test certificate. According to the certificate number, the customer can verify the source of the shipbuilding steel plates with the corresponding classification society near them.

The advantage of hot-rolled stainless steel plate is that it can eliminate the damage caused by 09CUPCRNI-B steel elements metal structure in the process of ingot casting to a certain extent, eliminate some tiny defects in the structure, refine the grains of stainless steel material, promote the structure of steel closer, and improve the performance of the material as a whole. This kind of lifting is mainly manifested in the rolling direction, which can make the 09CUPCRNI-B steel elements steel no longer isotropic to some extent, and some defects such as bubbles, cracks and looseness formed during pouring can be eliminated under high temperature or high pressure.
