(European Committee for Standardization EN10088-1-2005) X17CrNi16-2 Application: It is suitable for the production of high strength, toughness, plasticity and corrosion-resistant parts and components and load-bearing parts working in abusive wet media.

1.4057 is a martensitic stainless steel strength and toughness with a better kind of steel. It is a low carbon chromium-nickel corrosion resistant steel, with high strength and hardness. Oxidizing acids (a certain temperature, concentration of nitric acid, most of the organic acids), as well as aqueous solutions of organic acids have good corrosion resistance. Sub-temperature quenching can effectively inhibit the steel's high temperature tempering brittleness. Can make the steel brittle transition temperature is reduced, the toughness has been improved, fracture morphology from quasi-dissolution type to the tough nest type, the degree of enrichment of alloying elements to the matrix and δ - ferrite in the increase in the improvement of steel toughness at the same time still maintains a high level of strength. But the steel welding performance is not good, easy to produce cracks, so the manufacture of furniture, not suitable for welding.
