Super martensitic stainless steel is a new type of martensitic stainless steel that strictly controls the carbon content below 0.03% on the basis of traditional martensitic stainless steel and increases the nickel content. Compared with the traditional low-carbon martensitic stainless steel, super martensitic stainless steel not only has good ductility toughness and higher strength and hardness, but also has higher fracture toughness, underwater fatigue strength and abrasion resistance. After the martensitic stainless steel is normalized, lath martensite can be obtained, and after tempering at a certain temperature, further tempered martensite can significantly affect and improve the overall properties of the material. Predecessors studied super martensitic stainless steel normalizing at 1050°C and tempering between 500°C and 700°C, focusing only on its microstructure and mechanical properties, and did not study its abrasion resistance. In the study, the super martensitic stainless steel 1.4314 (S41500) was normalized and tempered once and selected part of…
