Product Name: Stainless steel wire (screw line, spring wire, bright wire, all soft lines, hydrogen back line, hanging wire, etc.) Grade: 201,302, 304, 310, 316,316L, 321,430,416, and other specifications: 0.02mm --- 12.6mm Surface: Smooth (Bright), matte (S-CO) forms: all soft, 1/4 hard, semi-hard, 3/4 hard, full hard, extra-hard stainless steel spring wire hardness There are the following: all soft | 1/4 hard | Semi-hard | 3/4 hard | full hard | extra-hard. Stainless steel spring wire temperature at 200 °, exceeding this value should choose to use high-temperature line. Stainless steel spring wire due to the elastic means in the quenched and tempered condition, and specifically for the manufacture of springs and elastic elements. Spring steel depends on the ability of elastically deformable stainless steel spring wire, i.e., within the prescribed range, the ability to withstand a certain elastic deformation of the load so that it does not appear in the permanent deformation after the load is removed.
