双节距滚子链条作为一种常见的传动力的装置，通过双曲线弧的“链子”设计，减小摩擦力，使用于动力比较大而运行速度比较慢的地方，比皮带传动有明显得优越性，例如坦克，气动压缩机等，但是传动速度不能太快，因为链条的柔韧性不如皮带传送。不锈钢链条特别适合耐腐蚀、清洁或某些化学品要求苛刻的领域以及高、低温场合中。按材质分类
１、采用优质产品1Cr18Ni9Ti或SS304不锈钢制造，具有耐酸，耐碱，耐冷热，寿命长等特点，广泛应用于食品、化工、制药、橡胶、印刷、剿丝等机械，并为各种进出口机械进行配套，是现代化设备的优良装备。
２、奥氏体不锈钢链系列，如304和316以及316L等材质具备优异的耐腐蚀性能，如酸、碱以及-40°~600°的高低温场合。相比较而言，316L具有更好的抗磁性、严苛温度的适应性以及耐化学腐蚀性。
３、马氏体不锈钢链系列，如2Cr13等，不仅具备有恰当的防腐能力，也具备与同等含碳量的碳钢的强度。
Double pitch roller chain as a common power transmission device, through the "chain" of the hyperbolic arc, reduce friction, for use in power relatively large and relatively slow speed than the belt drive wassuperiority, such as tanks, pneumatic compressors, etc., but the transmission speed is not too fast, because the chain flexibility as the belt conveyors. Stainless steel chain, especially for corrosion, clean, or certain chemicals require harsh areas and high and low temperature applications. Material classification
1, the use of high-quality products 1Cr18Ni9Ti or SS304 stainless steel, with acid and alkali, resistant to hot and cold, and long life characteristics, widely used in food, chemical, pharmaceutical, rubber, printing, destroy, such as silk machinery, and a variety of import and export mechanical facilities, modern equipment, excellent equipment.
Austenitic stainless steel chain series, such as 304 and 316 and 316L material with excellent corrosion resistance, such as acids, alkalis, and -40 ° ~ 600 ° high and low temperature situations. In comparison, the 316L has better anti-magnetic, the adaptability of the harsh temperature and chemical resistance.
3, martensitic stainless steel chain series, such as 2Cr13, not only with appropriate corrosion resistance also has the strength of carbon steel with the same carbon content.
