通过试验与试生产,找到了合理的生产工艺,对于不同的原料品种,采用了不同的使用方法。证实了硒比硫更易改善钢的切削性能,而它对钢的有害影响却比硫小得多。特别是对不锈钢的抗晶界腐蚀性能无影响,1Cr18Ni9Se与1Cr18Ni9相同。通过测试证实,该材料具有优良的抗咬性能,比一般不锈钢高2～4倍;摩擦系数也较低,还有一定的自润滑性,但自锁性能不变。 18年来为用户提供70多批共60多吨材,得到一致好评,经测试,加工及使用后,确认该材料已满足使用要求,所制造的核反应堆上的一些螺纹副及运动副,不再发生“咬伤”或“咬死”事故,从而在SS领域得到推广应用。
Through trial and trial production, found a reasonable production process, for different varieties of raw materials, using a different method of use. It is confirmed that selenium is easier to improve the machinability of steel than sulfur, and its detrimental effect on steel is much smaller than that of sulfur. In particular, no effect on the anti-corrosion properties of stainless steel, 1Cr18Ni9Se and 1Cr18Ni9 the same. The test confirmed that the material has excellent anti-bite performance, higher than the average stainless steel 2 to 4 times; lower friction coefficient, there is a certain degree of self-lubricating, but self-locking performance unchanged. Over the past 18 years to provide users with more than 70 batches of a total of more than 60 tons of material, has been well received, after testing, processing and use, to confirm that the material has to meet the requirements, the manufacture of some of the nuclear reactors and vice pairs of movement no longer occur “Bite” or “bite death” accident, which in the field of SS has been promoted.
