一、序高强度碳素弹簧钢丝(YB647—67及YB248—64Ⅰ组)具有强度高、弹性大、适于冷成型等优越的物理性能,而且生产成本较低,因而广泛用于军工和民用产品。我厂近几年来生产的高强度碳素弹簧钢丝虽然在质量上有所提高,但与国外同类名牌产品相比,还有一定的差距,其主要表现是:(1)性能不均,(2)韧性差,(3)绕簧成型性差,簧距不均。
A sequence of high strength carbon spring steel wire (YB647-67 and YB248-64I group) with high strength, flexibility, suitable for cold forming and other superior physical properties, and lower production costs, which are widely used in military and civilian products . Although the quality of the high-strength carbon spring steel wire produced by our factory in recent years has been improved, there are still some disparities compared with similar famous brand products in foreign countries. The main features are: (1) uneven performance, (2 ) Poor toughness, (3) around the spring forming poor, uneven spring spacing.
