Ferritic stainless steel
A stainless steel dominated by ferrite in the state of use. The chromium content is in 11%~30% and has the body centered cubic crystal structure. This kind of steel does not contain nickel, sometimes also contain a small amount of Mo, Ti, Nb when the elements of this kind of steel with high heat conductivity, low expansion coefficient, good oxidation resistance and anti stress excellent characteristics of stress corrosion, used formanufacturingthecorrosionresistanceofthe atmosphere, water vapor, waterandoxidizing parts. This kind of steel has some disadvantages, such as poor plasticity, plastic and corrosion resistance after welding, which limits its application.
Martensitic stainless steel
Stainless steel, which can adjust its mechanical properties by heat treatment, is generally said to be a kind of hardened stainless steel. Typical brands such as 2Cr13 Cr13, 3Cr13,, 4Cr13 etc.. The hardness is higher after the fire, and different tempering temperatures have different strength and toughness combinations, which are mainly used in steam turbine blades, tableware and surgical instruments. According to the differences in chemical composition, martensitic stainless steel can be divided into martensite and martensite chromium chromium nickel steel two. According to the mechanism of microstructure and strengthening, it can also be divided into martensitic stainless steel, martensite and semi austenite (or half martensite) precipitation hardening stainless steel and maraging stainless steel.

The application of AOD or VOD can greatly reduce the gap elements such as carbon and nitrogen, so this kind of steel can be widely used. E-BON the most excellent stainless steel company, which provide you with Stainless Steel Ice Cream Spoon in china.
Austenite ferritic duplex stainless steel
It is a stainless steel about half of the austenite and ferrite. In the case of low C, the content of Cr is in 18%~28%, and the content of Ni is 3%~10%. Some of the steel also contain Mo, Cu, Si, Nb, Ti, N and other alloy elements. This kind of steel with austenite and ferrite stainless steel body, compared with ferrite, the plasticity and toughness are higher, no room temperature brittleness, intergranular corrosion resistance and welding performance was significantly improved, while also maintaining a ferritic stainless steel 475 DEG C brittleness and high thermal conductivity, superplasticity etc.. Compared with austenitic stainless steel, it has high strength, intergranular corrosion resistance and chloride stress corrosion resistance.

The dual phase stainless steel has excellent corrosion resistance and is also a kind of stainless steel. E-BON the stainless steel specialist, hand crank coffee mill supplier.
