China's powder metallurgy standardization work adhere to the enterprise as the main body, market-oriented, in order to serve the development of non-ferrous metal industry as the focus, successively formulated and revised a large number of more effective, more adaptable to the market of powder metallurgy national standards and industry standards.
1、What are the national or enterprise standards for powder metallurgy?
Powder metallurgy can only check the national and industry standards, can not check the enterprise standards to check the national standards and industry standards only online.
2、Domestic powder metallurgy material FZ2265 what are the ingredients?
This is powder metallurgy bearings! National standard FZ is powder metallurgy bearings mean ah! 2265 in the first 2 refers to the copper base, the second 2 is the type of bearing, 65 is the oil density. FZ2265 main component is copper and zinc, zinc 8% ~ 11%, and a small amount of iron and carbon.
3, M42 high-speed steel raw materials with which national standards? It is powder metallurgy manufacturing.
U.S. ASTM A 600-1999 high-speed tool steel: M42 Electronic Technical Information UNS grade T11342 (UNS: in accordance with ASTME257 and SAEJ 1086, metals and alloys digital numbering). This standard does not specify a preparation process. It is possible to use either conventional metallurgical processes or powder metallurgical processes. M42 is the U.S. standard,, there is powder metallurgy, there is not, the domestic general is not powder, only very few manufacturers can do powder M42, such as metallurgical science and technology M42 is the U.S. standard, does not belong to the powdered steel.
China MIM introduces the knowledge about the national standard of powder metallurgy, hope this article can help you.
