Stainless steel wire mesh uses

First, understand the relevant definition of it is what

Also known as stainless acid-resisting steel.In practical applications, often weak corrosion resistant steel, stainless steel, the corrosion of the steel is called acid-resisting steel.Due to differences in the chemical composition of the two, the former is not resistant to chemical corrosion, and the latter is normally has no rust.The corrosion resistance of stainless steel alloy elements on the contained in steel.

Secondly, to understand its species

Stainless steel in organization is divided into: martensitic steel, ferritic steel, austenitic steel.In addition, according to the component is divided into: chromium stainless steel, chromium nickel stainless steel and chromium manganese nitrogen stainless steel etc..

1, ferritic stainless steel: Nanjing synchronous wheel contained 12% ~ 30%.Its corrosion resistance, toughness and can increase the welding with chromium increases the amount of resistance to chloride stress corrosion, performance is better than other types of stainless steel.

Fall into this category are Crl7, Cr17Mo2Ti, Cr25, Cr25Mo3Ti, Cr28 etc..Ferritic stainless steel for high chromium content, resistance to corrosion and oxidation resistance are better, but the mechanical properties and process performance is poor, much less force for acid structure and antioxidant used in steel.This kind of steel can resist the corrosive atmosphere, nitric acid and saline solution, and has high antioxidant properties, thermal expansion coefficient is small, for nitrate and food factory equipment, also can be made to work in high temperature parts, such as a gas turbine parts.

2, austenitic stainless steel: Cr is greater than 18%, still contain 8% of nickel and a small amount of molybdenum, titanium, nitrogen and other elements.Comprehensive performance is good, resistant to a variety of medium corrosion.Common grades of austenitic stainless steel 1Cr18Ni9, 0Cr19Ni9 etc..0Cr19Ni9 steel, wC<0.08% steel, labeled as "0".This kind of steel containing large amounts of Ni and Cr, the steel is austenitic state at room temperature.This kind of steel has plasticity, toughness, weldability and corrosion resistance good, in the oxidizing and reducing medium corrosion resistance are good, used for making acid equipment, such as nitric acid corrosion resistant containers and equipment lining, pipelines, equipment parts.Austenitic stainless steel with solid solution treatment, the steel is heated to 1050 to 1150 DEG C, and then cooling, in order to obtain single-phase austenite.www.aphcmetalmesh.com
