摘要：

目前国内NCu30-3-0.5合金锻件的应用领域不断扩大，其需求量也不断增加，但是缺少相应的标准，这给合金锻件的生产及进出口贸易等带来诸多不便。因此，对美国标准ASTM B 865-04进行修改采用，并结合锻压行业的实际情况和现有水平，进行了国家标准《NCu30-3-0.5合金锻件》的研制。该标准规定了多形状、多尺寸NCu30-3-0.5合金锻件的化学成分、力学性能、尺寸及其允许偏差、加工质量、取样、检验、拒收、复检、合格证及标识等要求。按此标准生产的NCu30-3-0.5合金锻件质量可达到国际先进水平。

Nowadays the quantity in application fields and demand of NCu30-3-0.5 alloy forgings in China are increasing, but the standard specification for them is relatively deficient, so there are many disadvantages on some aspects of forgings such as production, import and export trade, and so on. Consequently, the United States standard ASTM B 865-04 was modified and adopted, and combining the reality and current level of forging industry, the national standard 《NCu30-3-0.5 alloy forgings》was prepared. The standard specification for NCu30-3-0.5 alloy forgings with multi shapes and dimensions covers chemical composition, mechanical properties, dimensions and permissible variations, workmanship, sampling, tests, rejection, rehearing, certification, and product marking. The quality of NCu30-3-0.5 alloy forgings manufactured according to the standard specification reaches international advanced level.
