18-8 series stainless steel is 304?

Yes The standard components of 18-8 stainless steel are 18% chromium and 8% nickel, which can resist chemical oxidation. It is a non-magnetic stainless steel, and its metallographic structure will not be changed by heat treatment. This kind of stainless steel is No.304 in jis code, so it is also called 304 stainless steel.

Products such as: corrosion resistant containers, tableware, furniture, railings, medical equipment. GB brand is 0Cr 18Ni9.

Extended data:

Process flow: The process flow of the artistic processing method of color spraying of stainless steel products is: stainless steel products → screen printing → etching → alkali treatment → screen printing → oxidation coloring → alkali treatment → finished products. The technological process of etching stainless steel products is as follows: stainless steel products → screen printing → etching → alkali treatment → oxidation coloring → finished products.

The chemical coloring method of stainless steel does not use pigments and dyes, but soaks stainless steel in heated concentrated sulfuric acid chromium solution for chemical coloring, which is characterized by good food resistance. The ink used in this processing method should have very strong acid resistance, and generally use UV curing ink with special properties suitable for processing technology.

Stamping: Stainless steel products, especially stainless steel strips, are often stamped with a punch. Stamping includes two ways: straight punching and stretching. Generally, the hardness below 1/2 is stretch bending, and the hardness above 1/2 is straight punching.
