According to statistics ,about 76% of stainless steel products are 300 series in the world, so the nickel price fluctuations on the nickel-chromium stainless steel prices had a big impact. In recent years, due to the cost of nickel chrome stainless steel growth, consumers have to actively looking for alternatives.Chromium stainless steel and the low nickel stainless steel(eg 200 series) development gradually respected by all parties.Looking to the future, Chromium stainless steel and the low nickel stainless steel consumption ratio will have a tendency to increase.

200 series stainless steel (Cr-Mn-Ni)

Since the 1950s, the United States due to shortage of raw material of nickel, after in-depth research, successfully developed a series of high manganese austenitic stainless steel, 200 stainless steel. 200 series include: AISI 201 (16% ~ 18% Cr, 5.5% ~ 7.5% Mn, Ni, 3.5% ~ 3.5% < 0.25% N), 202, 205, and India J1, J4 (Cu), etc., and Cost 25% less than 304 stainlesss steel, suitable for weak corrosive environment in general use, such as household utensils, kitchen utensils and appliances, interior decoration and so on, the poor welding performance. The recent development of 204 Cu (3% Cu), compared with the grade 304 stainless steel, the strength is higher, the cold working more excellent performance, the corrosion resistance is nearly 304 stainless steel, likely to replace 304 stainless steel become widely used.

400 series stainless steel

400 series development trend for adding trace Nb, Ti, Cu, Al improve deep drawing, welding, corrosion resistance, antimicrobial properties and resistance to high temperature strength, etc., can be partly replacing 304 stainless steel, the main steel grade: jil SUS430LX, 430, 444, 445 m2, NSS 477 m1, etc. The United States and Japan have been widely used in automobile exhaust tube (409, 410), washing machines (430), meal kitchen utensils and appliances, medical equipment, water heater, roof, wall, power plants, etc
