[0035] Among them, the 13Cr martensitic stainless steel (WO2007029626) applied by "The Thomson Corporation" adds Ni, Mo, Cu and other elements to improve the plasticity and toughness of the 13Cr martensitic stainless steel, and at the same time, the hardenability is also improved. It uses Ni to expand the high-temperature austenite region, uses Mo...
Embodiment 2
[0040] According to the chemical composition range designed by the present invention, 5 furnaces of steel were smelted on the vacuum induction furnace, which we named as No. 1 furnace, No. 2 furnace, No. 3 furnace, No. 4 furnace, and No. 5 furnace respectively. The chemical composition is shown in Table 2.
[0041] All the 5 furnaces of molten steel were poured into small steel ingots, and the steel ingots were sand-cooled with molds, and demoulded after cooling to room temperature. After demoulding, the surface of the ingot is ground and forged, and finally heated to 1200°C and hot-rolled into a plate. Sample processing is carried out on the plate according to the requirements of the national standard. The steel was annealed at 760°C and quenched at 1000°C respectively, and its strength, hardness, plasticity and corrosion resistance were tested. The corrosion resistance test adopts the salt spray corrosion method, and the corrosion period is 120 hours. The test results are ...
