SUS403 / AISI403 Martensitic Stainless Steel Plate

Established in 1974, with more than 36 years' development, we have become the largest high carbon chromium stainless steel producer in China. Located in Jiangsu Province, it takes one hour from Shanghai. Up to now, it covers an area of 166.5 thousand square meters and has about 500 staff. The annual production capability of stainless steel material increased over 50 thousand tons. They are widely used in Ball bearings and races, gage blocks, molds, cutlery, valve components, knives and measuring instruments. Two parts of business as following: The first part: Specialized in producing high carbon chromium hot-rolled and cold-rolled stainless steel bars, strip, sheet, plate and coils, such as 440A ( 7Cr17, 7Cr17MoV ), 440B ( 8Cr17, 8Cr17MoV ), 440C ( 9Cr18,9Cr18MoV, 9Cr18Mo, 11Cr17 ), 6Cr13, 6Cr14, 6Cr14MoV, 8Cr13MoV, 8Cr14MoV, AUS8, AUS10, 9Cr13MoVCo,9Cr14MoV, 3Cr13Mo, 2Cr14Mo, 4Cr13Mo, 4Cr14MoV etc. The second part: having stock for 430, 405, 409L, 410, 410S, 441, 443, 444, 420J1, 420J2, 436, 439, 309S, 310S etc from the mill of Tisco, Bao steel, K.D.K.C, Baoxin, Jisco etc. Have established good-cooperation with these mills, and have technical communication with them regularly. We have integrated-system stainless steel production line which includes electro- smelting, AOD furnace refining, LF furnace, electroslag furnace, forging, hot continuous rolled, cold rolled, Wire Drawing Machine etc. Our company also has complete inspection machines for quality control, including metallographic examination, spectrum, cupping machine, Rockwell hardness tester, Vickers hardness tester, salt spray test machine, surface roughness tester, etc. These equipments can make the whole production process under effective control.
