Related knowledge:

Stainless steel is often divided into: martensite steel, ferritic steel, austenitic steel, etc.In addition, can be divided into: chromium stainless steel, chromium nickel stainless steel and chromium manganese nitrogen stainless steel.


1、 Ferrite stainless steel: 12% ~ 30% chromium.Its corrosion resistance, toughness and weldability improve with the increase of chromium content.Crl7, Cr17Mo2Ti, Cr25, Cr25Mo3Ti, Cr28 and so on fall into this category.Ferritic stainless steel because of high chromium content, corrosion resistance and oxidation resistance are better, but mechanical and technological performance is poor, mostly used for acid resistance structure and oxidation resistance steel.This kind of steel can resist the corrosion of atmosphere, nitric acid and brine solution, and has the characteristics of good oxidation resistance at high temperature, small coefficient of thermal expansion, etc., it is used for nitric acid and food factory equipment, and also can make parts working at high temperature, such as gas turbine parts and so on.


2、austenitic stainless steel: contains chromium more than 18%, also contains about 8% nickel and a small amount of molybdenum, titanium, nitrogen and other elements.Good comprehensive performance, can withstand a variety of medium corrosion.Common brands of austenitic stainless steel are 1Cr18Ni9, 0Cr19Ni9, etc.WC of 0Cr19Ni9 steel <0.08%, marked as "0" in steel sign.This type of steel contains large amounts of ni and cr, which makes the steel austenitic at room temperature.This kind of steel has good plasticity, toughness, weldability and corrosion resistance, good corrosion resistance in oxidizing and reducing medium, used to make acid resistance equipment, such as corrosion resistance container and equipment lining, conveying pipe, nitric acid resistance equipment parts.Austenitic stainless steel is generally treated by solid solution. The steel is heated to 1050 ~ 1150℃ and then cooled by water to obtain single-phase austenitic structure.


3、 austenitic - ferrite dual phase stainless steel: both austenitic and ferrite stainless steel advantages, and with superplasticity.Austenitic and ferritic tissues each account for about half of stainless steel.With low C content, Cr content ranged from 18% to 28%, and Ni content ranged from 3% to 10%.Some steels also contain Mo, Cu, Si, Nb, Ti, N and other alloying elements.This kind of steel has the characteristics of both austenitic and ferritic stainless steel. Compared with ferritic stainless steel, it has higher plasticity and toughness, no brittleness at room temperature, significantly improved resistance to intercrystalline corrosion and welding performance. Meanwhile, it also maintains the brittleness of ferritic stainless steel at 475℃ and high thermal conductivity, with the characteristics of superplasticity.Compared with austenitic stainless steel, the strength and resistance to intercrystalline corrosion and chloride stress corrosion are significantly improved.Duplex stainless steel is a kind of nickel - saving stainless steel with excellent corrosion resistance.


4、Martensitic stainless steel: high strength, but poor plasticity and weldability.Martensite stainless steel commonly used grades are 1Cr13, 3Cr13, etc., because of high carbon content, it has higher strength, hardness and wear resistance, but corrosion resistance is slightly poor, used for mechanical performance requirements, corrosion resistance requirements of some general parts, such as spring, turbine blade, hydraulic pressure valve.This kind of steel is used after quenching and tempering.
