Spring tempering note what are respectively?

Spring tempering note what are respectively? Summarized as follows: (spring manufacturer 1) Can't in order to enhance temperature method to minimize the time to play yellow for tempering is solved. ( 2) Strength: increase with increasing tempering temperature, the strength increased slightly after reduction. Good tired features * yes temperature slightly low strength larger temperature. ( 3) Reducing: carbon steel bullet yellow tempering diameter becomes smaller, so the coil spring should be embedded when some specifications. ( 4) Play yellow heat tint: heat tint, associated with the temperature and residual in the surface of stainless steel wire, color is not fit with the temperature around or the cyclone related inside the furnace, if looking forward to color symmetry, method to manage good furnace and feeding method; If parts have oil or fingerprints, after tempering will rub off. ( 5) Tempering temperature: general selection of tempering temperature - in 250 200-280 ℃, if choose 250 ℃ solution to stainless steel wire, although can enhance the compressive strength, but plastic deformation will damage, can cause tension spring hooks or torsional spring generated when the bent leg broken. ( 6) Compression spring: after maul slight cryogenic tempering can reduce the deformation. ( 7) Tension spring: after tempering solve initial geostress also have damage, should consider when setting error to tolerate loss. ( 8) Torsional spring: spring coiling in 280 ℃ tempering after solved, such as coil spring to reproduce after processing, cryogenic tempering temperature is 250 ℃. ( 9) Tension spring hook and torsional spring arm: parts will change after tempering, if have accurate site rules, it should be change.
