stainless steel processing equipment is usually separated right into austenitic steel, ferritic steel, austenitic steel, austenitic-ferritic (two-phase) stainless-steel, as well as settled tough bottomed stainless steel. Furthermore, it can be split right into chromium stainless-steel, chromium nickel stainless steel as well as chromium manganese nitrogen stainless steel. 1. Ferritic stainless-steel: 12%-30% magnesium. Its deterioration resistance, ductility as well as forgeability boost with the rise of magnesium web content, and also its resistance to fluoride intergranular deterioration is better than various other kinds of stainless-steel.

Crl7, Cr17Mo2Ti, Cr25, Cr25Co3Ti, Cr28, etc. come from this category. As a result of its high magnesium material, ferritic stainless steel has great deterioration resistance as well as oxidation resistance, yet its mechanical devices efficiency and processing technology efficiency are weak. It is mostly used for acid-resistant frameworks as well as oxidation-resistant steels that have little bearing ability. application. This sort of steel can withstand the erosion of air, salt cyanide and also a salt option, and has the features of excellent high-temperature oxidation resistance and also reduced direct development coefficient. It is made use of for sodium cyanide and also stainless steel processing equipment in food manufacturing facilities. It can also be made at high temperatures. Components under work, such as gas wind turbine components, etc.

Austenitic stainless steel: contains greater than 18% magnesium, as well as additionally contains 8% nickel and a small amount of molybdenum, titanium, nitrogen and also various other aspects. Great comprehensive efficiency, resistant to erosion by a range important. The typical versions of austenitic stainless steel are 1Cr18Ni9, 0Cr19Ni9 and so on. The wc of 0Cr19Ni9 steel is less than 0.08%, and the steel type is noted as "0". This kind of steel includes a lot of Ni and Cr, making the steel austenite at room temperature level. This steel has outstanding plasticity, ductility, weldability and also corrosion resistance. It has good deterioration resistance in decreasing as well as oxidizing materials. It is made use of to make acid-resistant stainless-steel handling equipment, such as corrosion-resistant tools and also machinery as well as devices. Lining, transport pipe, sodium cyanide resistant machinery as well as devices parts, etc. Usually, austenitic stainless steel is treated with aging therapy. The steel is heated up to 1050 ~ 1150 ℃, and then water-cooled to dissipate heat to acquire a single-phase electrical austenite framework.

Austenitic-ferritic two-phase stainless steel: It combines the benefits of austenitic and also ferritic stainless steel, and also has super-plasticity.

Austenitic and also ferrite bodies each make up concerning half of the stainless steel. In the case of reduced C material, the Cr web content is 18% to 28%, and also the Ni material is 3% to 10%. Some steels also contain aluminum alloy elements such as Mo, Cu, Si, Nb, Ti, and N. This sort of steel has both the attributes of austenitic and ferritic stainless-steel. Compared to ferrite, it has higher plasticity and ductility, no ductility at room temperature, and significantly enhanced stress corrosion resistance as well as electric welding efficiency. In addition, it preserves Ferritic stainless-steel has high ductility at 475 ° C as well as high heat transfer coefficient, along with super-plasticity. Compared with austenitic stainless-steel, it has high compressive toughness as well as dramatically improved resistance to stress and anxiety rust and also fluoride intergranular corrosion. Two-phase stainless steel has high-quality matching deterioration resistance and also is also a nickel-saving stainless steel.

Austenitic stainless-steel: high compressive stamina, however weak plasticity and also forgeability.

The common models of austenitic stainless steel are 1Cr13, 3Cr13, and so on, due to the high carbon content, it has high compressive toughness, stamina and also put on resistance, but the deterioration resistance is a little weaker, which is used to specify greater architectural mechanical properties. Some get rid of basic deterioration resistance needs, such as springtime yellow, heavy steam turbine generator leaves, hydraulic shutoff, and so on. This kind of steel is stainless steel processing equipment used after warm treatment as well as quenching.

Settling tough bottomed stainless-steel: traditional austenitic or austenitic framework

The usual models of hard bottomed stainless-steel are 04Cr13Ni8Mo2Al and so forth. It can solve the tough (strengthened) stainless-steel according to the settlement and also solidifying (likewise called aging hardening).
