2) Quenching temperature 950 ~ 1050 ℃, oil quenching, tempering temperature 280 ~ 350℃, air cooling, tensile strength 1100 ~ 1730mpa, elongation 10% ~ 22%, impact toughness 25 ~ 50J / cm2, hardness 187 ~ 286HBW.
Features and application scope
1Cr17Ni2 steel is a martensitic stainless and acid-resistant steel with high strength and hardness.
1Cr17Ni2 steel has good corrosion resistance to partially oxidizing acids and organic acid aqueous solution at a certain temperature. It is suitable for manufacturing plastic molds and transparent plastic product molds under the action of corrosive media. However, the steel has poor welding performance and is easy to produce cracks. It is not suitable to weld when manufacturing molds.
