Abstract

The invention discloses a machining process of a stainless steel material special for faucets. The machining process comprises the following steps that (1) a steel blank raw material is smelted; (2) coarse-smelted molten steel is subjected to refining; (3) pouring is carried out to obtain a steel blank; (4) the steel blank is subjected to first annealing treatment; (5) the steel blank is subjectedto thermal treatment and then hot rolling; (6) hot-rolled stainless steel is subjected to first acid pickling; (7) the stainless steel is cold-rolled; (8) the stainless steel is subjected to secondary annealing treatment; (9) the stainless steel is subjected to electrolysis and secondary acid pickling; and (10) the surface of the stainless steel is subjected to polishing and burr removal, and thus the stainless steel material special for the faucets is obtained. The prepared stainless steel is dense in material structure, smooth in surface, good in corrosion resistance, excellent in mechanical performance and easy to machine.

Description

technical field [0001] The invention belongs to the technical field of stainless steel materials, and in particular relates to a processing technology for special stainless steel materials for faucets. Background technique [0002] Faucets are not only widely used in daily life, but also in other fields such as laboratories, factory crafts, etc., and with the development of the economy, faucets used in daily life are increasingly required to be cheap, high-quality, Beautiful, so the faucet manufacturing process is also constantly using new materials and new technology. The faucets currently used are generally made of brass, stainless steel and other materials. Among them, brass is easy to stretch and easy to make with common processes, so it is widely used in the faucet manufacturing process. Because pure copper is soft and in order to reduce costs, When making a faucet with brass, zinc and a small amount of lead and other elements are added to the brass. However, because ...
