202 seamless stainless steel pipe is belong to the 200 series.Early development is based on nickel, manganese, nitrogen generation instead of 18-8 cr-ni austenitic stainless steel.The grade of steel corrosion resistance, mechanical properties, high and low temperature performance, process performance, such as decorative excellent comprehensive performance.In various fields are widely used in civilian to military, civil construction decoration.Household appliances, kitchen equipment and utensils, transportation, environmental protection, municipal construction; Military aviation, aerospace, nuclear industry, ships; In the field of industrial chemical, fertilizer, petroleum, textile, printing, paper making, energy.Used in automobile, train, subway car component accordingly.Subsequently developed S21400 (XM - 31), S24000 (XM - 29, Nitronic33), S28200 (Carpenter18-18 plus), S21900 (XM - 11, Nitronic40), S20910XM - 19, Nitronic50) and YUS120 high strength, corrosion resistant stainless steel.XM - 31, XM - 11 for aviation, cryogenic system, non-magnetic parts.XM - 11, XM - 19 is better than 316 corrosion resistance, used for pumps, valves, fasteners, Marine materials, heat exchanger, spring, etc.

1990 new (Cr17Ni5 AISI203XM - 1, 5 mo0. 25 cu2s0. 25) free-cutting steel.AMCO company development S20161 (Nitronic60, Cr17Ni8. 5 mn8. 5 si4n wear-resistant self-lubricating stainless steel is also included in the standard.Almost all along the Ni Mn - N generation,Instead of the corresponding 300 series stainless steel,also some CrMnNi high strength steel, no magnetic steel.Lists the Mn, N with Ni non-magnetic stainless steel.

YUS130 (C0.2 Cr21Ni6Mn9N0. 3) is relatively high Cr, N material,SUS205 NASNM15, NTKS - 4 is almost entirely in Mn, N instead of the Ni Cr17Mn15N0. 35 steel.NASNM15M in order to obtain better corrosion resistance decrease C to maintain a certain amount of Ni.Because the steel grade of Mn content in more than 10%,greatly increase the solubility of N in steel,So N content were 0.3 ~ 0.4%,after solid solution treatment can be fully austenitic organization and very stable,after the cold work without high magnetic strength can be obtained.

Physical properties of 202 seamless stainless steel pipe

202 with the corresponding 300 series steel and the physical properties of the solid solution treatment conditions.The physical properties of 200 series and 300 series is not much difference,almost is considerable.But after the cold working through changes in the rate of magnetic.Due to different degree of cold work when induced martensite,through the magnetic rate is smaller than 300 series than in 200.

Mechanical properties of 202 seamless stainless steel pipe

202 is different from other 200 series materials.Like the 301 302  also belong to a system of metastable austenite stainless steel.It has a larger work hardening.The steel strain hardening curve.202 martensite generated very little.Work hardening depend mainly on abnormal.This kind of solid solution treatment state hardness around HV250,after cold rolling strengthening higher intensity,Hv can reach 500.But in this state through magnetic rate remains below 1.005.

The development prospects of 202 seamless stainless steel

CrMnN high nitrogen austenitic stainless steel with high strength, toughness, high abrasion resistance, nonmagnetic, corrosion resistance and other properties.In a wide variety of industry needs.In the future in many aspects, the following will be a bigger development:

1,High strength, high corrosion resistance and good low temperature toughness of high nitrogen CrMnNiN steel, for aircraft, aerospace and ship mentioned performance of the rods, wire, forgings, plate, sheet to make a container, pipe, valves, cables, etc.

2,Wear-resisting, corrosion resistance, high toughness, high nitrogen austenitic stainless steel CrMnN can provide corrosion for mining industry, wear-resisting machinery and equipment, mining equipment material.

3,Non-magnetic, high strength, corrosion resistant, high nitrogen austenitic stainless steel, CrMnMoN can provide non-magnetic drill collar for oilfield, provide no magnetic power generator retain
