Super austenitic stainless steel
When the PREN of chromium-nickel austenitic stainless steel is measured at a rate lager than 40%, it can be called the super austenitic stainless steel. The super-austenitic stainless steel is mainly developed for the solution of the deficiency of the original high molybdenum (> 4%) chrome-nickel austenitic stainless steel when containing CI-, such as pitting corrosion resistance, crevice corrosion resistance and tissue thermal stability under the harsh corrosion. conditions.
Ferritic stainless steel
Ferritic stainless steel is a kind of stainless steel with body centered cubic structure. Its carbon content is less than 0.02%, and the chromium content is between 10.5% ~32%. It is ferritic tissue both at high temperature and room temperature. It is also a kind of stainless steel that cannot be strengthened by heat treatment. This stainless steel has wide application range and excellent comprehensive performance.
Martensitic stainless steel
The mechanical properties of martensitic stainless steel can be adjusted by heat treatment. It is a kind of harden-able stainless steel. Typical brands are Cr13, such as 2Cr13,3Cr13,4Cr13, etc. It has high hardness after quenching, and with different tempering temperatures, it can have different strong-toughness combination. It is mainly used in steam turbine blade, tableware, surgical operating instrument.
Austenitic Stainless Steel Tube
Austenitic cr-ni stainless steel includes the famous 18cr-8ni steel and the series of high cr-ni steels developed by adding Cr and Ni contents and adding Mo, Cu, Si, Nb, Ti and other elements. Austenitic stainless steel is non-magnetic and has high toughness and plasticity, but the strength is low, it can not be strengthened by phase change, can only be strengthened by cold processing.
Super Duplex Steel,
Dual phase stainless steel has + double phase structure, so its performance characteristics of austenitic stainless steel and ferrite stainless steel characteristics, is a class of high strength and corrosion resistance of the best stainless steel. Generally, in the case of low C content, Cr content is between 18% and 28%, and Ni content is between 3% and 10%. Some steels also contain alloying elements such as Mo, Cu, Nb, Ti and N.
Nickel base alloys, titanium alloys and iron - nickel base alloys
Nickel-based alloy is a kind of alloy which has high strength and anti-oxidation corrosion ability at 650 ~ 1000℃. According to the main properties and subdivided into nickel-based heat resistant alloy, nickel-based corrosion resistant alloy, nickel-based wear resistant alloy, nickel-based precision alloy and nickel-based shape memory alloy. The superalloy is divided into iron base superalloy, nickel base superalloy and cobalt base superalloy. The nickel-based superalloy is referred to as nickel-based alloy.
