China Cold Work High Speed Mould Steel D2 SKD11 Tool

you need to use low-temperature tempering. Both have advantages and disadvantages.After tempering, it is with better toughness and increase the rupture resistance. The low-tempering has good abrasion resistance and long service life. Features:(1) Good Wear-Resisting,Good Quenching,Less Deformation (2) Heat-Treated Steel,Hardness:HRC 58-62 Degree External and Internal Hexgon Steel tube_Shandong YHT Steel has equiped with cold drawning production line.And the cold drawing machines are equiped high precision mould. Our cold drawn special shaped section tubes and special shaped steel bars are widely used in the applications such as Machinery, light industry, Hardware machinerym, Standard Machine parts, bicycle, automobile, motobike, textile machinery, power transformer, and some other Failure analysis of a steel tube joint perforated by Oct 01, 2012 · The tensile test data from the failed steel tube and data from 20Mn2 steel having undergone quenching and tempering show that the yield strengths of both steels are similar, but the failed steel tube has a lower tensile strength, a higher elongation, a higher area contraction and a

Seamless Carbon Steel Pipe - Steel Pipe - Seamless Steel Pipe

Description. Seamless carbon steel pipe is the kind of seamless steel pipe which is made from carbon steel billets as the basic material. The carbon seamless steel pipe has no seam or weld-joint around its body by internal seamless welding process. Due to the tough and flexible nature of carbon steel, the carbon steel seamless pipe have excellent finishing, better durability and high strength list steel alloys, list steel alloys Suppliers and offers 1,697 list steel alloys products. A wide variety of list steel alloys options are available to you, such as standard, material, and applicable industries.Chemical composition, Mechanical - steel-gradesGBT 30Mn2 Steel Physical Properties by Longhai special steel - China steel suppliers E-mail:[email protected] Finished goods condition:hot forging/hot rolling + annealing/normalizing + tempering/quenching + tempering/any conditions based on the customer's requirement Surface conditions:scaled (hot working finish)/ground/rough
