Stainless steel cap is welded on the pipe end or installed in the pipe outer thread on the cover wall pipe fittings, used for sealing pipe.
Method for heat treatment of stainless steel head:
1, softening annealing: the main purpose is to decompose carbide, the hardness decrease, and improve the processing performance, the spherical stone cast iron, for the purpose of obtaining a very high fertility iron organization.
2, normalization treatment: mechanical properties of castings that are mainly improved or made entirely of iron and are evenly distributed. ,
3, quenching: mainly to obtain higher hardness or abrasion strength, simultaneously to very high surface wear resistance characteristics.
