ZBY186-83仪表轴尖用钴40稀土合金标准系立足于该合金的优良特征,结合生产实际,面向用户之所需,针对过去同类材料标准的缺点与不足,并增加了多项指标而制订的.增加的指标有:出厂材料的抗拉强度、硬度、反复弯曲次数及硬度均勻性等;还首次规定用磁天平测定磁化率,并对材料内部质量(夹杂物)进行评定和限制以及修正不合理的试验方法等.起草过程中,各有关单位做了大量试验验证工作,使每项性能都有充分的科学依据,既满足了用户对材料的高要求,又立足于生产厂的现实条件,对生产和使用都是切实可行的。执行此标准,显著提高了成品率和经济效益。
ZBY186-83 instrument shaft with cobalt 40 rare earth alloy standard department based on the excellent characteristics of the alloy, combined with the actual production, user-oriented needs, in the past similar materials standards for the shortcomings and deficiencies, and increased the number of indicators formulated Increase in the indicators are: the tensile strength of the factory material, hardness, repeated bending frequency and hardness uniformity, etc .; for the first time the provisions of magnetic susceptibility measured by magnetic balance, and material quality (inclusions) to assess and limit and amend not Reasonable test methods, etc. In the drafting process, all relevant units did a great deal of testing and verification to make each performance have sufficient scientific basis to satisfy not only the high requirements of users for materials but also the realistic conditions of production plants, For production and use are feasible. The implementation of this standard, significantly improve the yield and economic benefits.
