Martensitic stainless steel heat treatment can be adjusted by the mechanical properties of stainless steel, stainless steel tables and chairs layman's terms, it is a class of hardened stainless steel. Typical grades for Cr13 type, such as 20Cr13, 30Cr13, 40Cr13 like. High hardness after quenching, tempering temperature with different combinations of strength and toughness, mainly used for steam turbine blades, cutlery, surgical instruments. According to differences in the chemical composition of stainless steel furniture manufacturers, martensitic stainless steel can be divided into martensitic chromium steel and martensitic chrome-nickel steel categories. Depending on the organization and strengthening mechanism, it can be divided into martensitic stainless steel, martensitic and semi-austenitic (or semi-martensitic) precipitation hardening stainless steel and maraging stainless steel. 1 chemical corrosion of stainless steel, surface contamination: adhering surface of the oil, dust and acid, alkali, salt and other under certain conditions into the corrosive medium, and some elements of stainless steel parts in stainless steel furniture made chemical reaction to produce chemical corrosion and rust. 2, surface scratches: various scratches destruction of the passive film, reduced ability to make stainless steel protective reaction prone to chemicals and solvents, chemical corrosion and rust. 3, cleaning: Cleaning is not clean after pickling passivation resulting residue retention, direct corrosion of stainless steel pieces (chemical corrosion).
