Stainless steel is the main component of low-carbon nickel chromium alloy steel, nickel and chromium in accordance with the ratio of nickel into stainless steel and chrome series stainless steel series. Stainless steel in accordance with its organizational structure into austenite, martensite, ferrite and precipitation hardening stainless steel. Appearing on the market its high-quality stainless steel with chromium content should not be less than 18% nickel content of not less than 10%. Stainless steel sinks are now hot bar with stainless steel plate (thickness less than 3mm for plate thickness greater than 3mm for the plate).

stainless steel jewelry  Wholesale: Production

1. stainless steel jewelry  Wholesale: raw materials

Domestic stainless steel sink manufacturers of raw materials used for the 0.8-1.0MM thick, commonly used models for the Japanese (JIS) SUS304, corresponding to the Chinese (GB) 0Cr18Ni9 (0Cr19Ni9). Thin sheet over the sink affect the service life and strength, too thick easy to damage the washing utensils.

2. stainless steel jewelry  Wholesale: process

There are two kinds of stainless steel sink manufacturing process.

First, welding, stamping groove side, respectively, and Aqueduct, the two connected by welding, grinding of the weld to fill the surface treatment, generally in the facade can not see the weld marks. This production method is simple, small and simple die stamping equipment can generally use about 0.5-0.7MM stainless steel plate, and less wear and tear production, relatively low cost.

The other is a molding method, sink into with a single piece of sheet metal press, and on processing equipment, mold demanding, as a molding of the plate for high quality and scalability, the general use of 0.8-1MM plate stamping, using whole die, stamping equipment imports. Since the production of sheet forming in one cutting edge of loss, coupled with the molds and equipment investment, and therefore high cost.

Matte surface treatment to the main tank, there drawing, grinding, etc., so even if the old, scratch the above also be seen.
