Martensitic stainless steel heat treatment can be adjusted by the mechanical properties of stainless steel, layman's terms, it is a class of hardened stainless steel. Typical grades for Cr13 type, such as 20Cr13, 30Cr13 tempered stainless steel furniture, 40Cr13 like. High hardness after quenching, tempering temperature with different combinations of strength and toughness, mainly used for steam turbine blades, cutlery, surgical instruments. Based on differences in the chemical composition of stainless steel furniture, 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. Stainless steel corrosion-resistant stainless steel equipment production process will be the performance of damage, as well as some of the substances affecting the surface defects, such as: dust, iron or embedded floating iron, hot temper color, and other oxide, rust, burr grinding, welding arc mark, weld spatter, flux, welding defects, oil and grease, residual adhesive and paint, chalk and marker pen and India and so on. The vast majority are ignored because of their harmful effects do not pay attention or not. However, they have a protective oxide film of potential hazards. Once the protective film is damaged, thinning or other methods to make changes in stainless steel furniture manufacturers of stainless steel will begin to corrode below. Corrosion is generally not over the entire surface, but at or around the defect. This is usually localized corrosion pitting or crevice corrosion, the two corrosive to the depth and breadth of development will be, but most of the surface from erosion.
