Detailed Product Description: | Spring steel according to their way of processing molding thermoforming and cold forming into two categories, because the different processing methods, the subsequent heat treatment in different ways, as follows: A spring of hot forming heat treatment Diameter or thickness greater than 10-15mm large spring, mostly drawing of hot rolled steel wire rod or steel. Processing and heat treatment: heating to the first spring steel quenching temperature 50-80 ℃ higher than normal under the conditions of hot roll forming, and then quenching + tempering temperature to obtain the elastic limit and excellent fatigue strength tempered sorbite. Spring steel should be used in quenching the oxidation of low or no oxygen equipment, such as salt bath furnace, stove and other protective atmosphere to prevent oxidation and decarbonization. Spring steel heat treatment even after shot peening treatment, enhanced surface, residual stress and improve fatigue strength. Hot rolled spring steel used in process: flat steel cutting -> bend forming the heating medium temperature after heat tempering + quenching + Shot -> packaging. 2 springs of cold forming heat treatment Pieces of diameter less than 8mm spring, cold roll forming cold drawn steel wire used. Cold-drawn steel wire manufacturing process and subsequent heat treatment, mainly the following three categories: 1) cold-drawn steel wire lead bath treatment First continuous wire drawing three times the total deformation of 50%, then heated to a temperature above Ac3 to austenitizing, followed the lead bath at 450-550 ℃ isothermal process, the austenite into sorbite organization . Yield strength 1600Mpa, cold roll forming, annealing at 200-300 ℃ to eliminate stress. 2) oil quenching and tempering steel Wire drawing to the treatment size after the oil quenching and tempering. Such as the strength of steel wire lead bath treatment, but the performance of uniform, low cost. Cold roll forming, de-stress treatment. 3) annealed wire Drawing the wire to the required size, and then annealed. After softening the steel cold roll forming, and subject to temperature tempering after quenching in order to obtain the required mechanical properties.
