Nanjing Hengjie Industrial Co., Ltd. is a joint-stock company. The company focuses on providing high value-added spring steel products at the beginning of establishment, and creates more values for users. We take "quality first" as company marketing way, "create future, insist perfection and particularity" as operation principle. Nowadays, we own many senior engineers with more than 15 years' experience, 3 intensive processing of advanced production lines and full sets of testing equipment.From hot rolled- annealed- cold rolled (cold drawn, peeled) - heat treatment (oil quenched, lead quenched) to shipment, each process has been strictly tested through machine and technician, to ensure that the products' qualified rate reaches 98.5% or more. We strive to achieve zero defect.At present, our spring products include: oil tempered steel wire( FDCrSi, FDCrV, VDCrSi, VDCrV, TDCrV, etc.); cold drawn round steel bar (SAE9254, SUP12V, 55Cr3, 55CrSi, 60Si2CrVA, SUP6, SUP7, SUP9, etc.); peeled round bar (55Cr3, SAE9254, SUP12V, 55CrSi, 60Si2CrVA, SUP6, SUP7, SUP9, etc.); cold drawn square steel; taper spring bar; cold rolled spring strip steel (65Mn, 60Si2Mn, 55CrMnA, 50CrV, SUP6, SUP7, SAE5160, etc.); hot rolled wire rod; hot rolled round bar; hot rolled spring flat steel (SUP9, SUP6, SUP7, SAE5160H, SAE6150 etc.).Meanwhile, except main spring steel products, we have developed free cutting steel products, from hot rolled to cold drawn, including cold drawn hexagon, cold drawn round steel, cold drawn square steel and cold drawn irregular steel. The size is 2mm-130mm, and steel grade is C1118, 12L14, 1215, Y15Pb, Y40Mn, Y45Pb, S45CF, S45CL, Y15, Y35, SUM24L, SUM42, 11SMnPb and so on.In order to further satisfy the needs of customers, we independently research and develop the irregular steel products which are widely used in various kinds of mechanical equipment.Besides deep processing products, we are also as an agent of alloy steel bar from famous steel mills. Round steel: 12mm-1000mm; square steel: 10mm-130mm. The steel grade: S10CB-S45CB, 4140, 4340, 52100, SUP9, 55CrSi etc. Nowadays, our products have been exported to 19 countries and been used in car, mining, medical treatment, the train, aviation, aerospace, ship, textile and other fields. Excellent quality and considerate services are complimentary by clients.For many years, we have been still continually promoting our management, improving techniques, searching and developing new products constantly to help customers improve product quality and reduce cost.
