304 stainless steel sheet is a common material in stainless steel. It is a grade of stainless steel produced following the American ASTM standard. It has a density of 7.93 g/cm³ and is also called 18/8 stainless steel in the industry. High temperature resistant to 800℃, with good processing performance and high toughness, it is widely used in industry and furniture decoration industry and food and medical industry. Next, I will introduce you to the 304 stainless steel sheet.
How wide is the application range of 304 stainless steel sheets?
How to process 304 stainless steel sheets?
What rust causes should be paid attention to for 304 stainless steel sheets?
304 stainless steel sheet is the most widely used chrome-nickel stainless steel. As versatile steel, corrosion resistance, heat resistance, low-temperature strength, and mechanical performance are excellent. It has excellent heat processing performance such as press and bending, and no heat treatment hardening. 304 stainless steel sheet is suitable for food processing, storage, and transportation. Has good processing properties and weldability. Panel type heat exchanger, Jacobi tube, household products (1, 2 kinds of tableware, cupboard, indoor pipe, water heater, boiler, bathtub), car parts (wipers, mufflers, press products), medical equipment, building materials, chemicals, chemicals, food industry, Agriculture, ship parts, etc. 304 stainless steel sheet is a nationally recognized food-grade stainless steel.
Etching method: The etching method is to screen-print an acid-resistant protective film on the surface of a 304 stainless steel sheet, and then etch with ferrous chloride solution to form an artistic pattern.
Color spray method: The color spray method sprays pigment particles on 304 stainless steel sheets after screen printing to form a pear-like surface and form an artistic pattern.
Process: The process of color spray art processing of 304 stainless steel sheet products is: 304 stainless steel sheet products → silk screen → etching → alkali treatment → screen printing → oxidation coloring → alkali treatment → finished product.
The chemical coloring method of the 304 stainless steel sheet does not use pigments and dyes. Instead, 304 stainless steel sheet is soaked in a heated concentrated chromium sulfate solution for chemical coloring, which is characterized by good food resistance. The ink used in this processing method must have very strong acid resistance and generally use UV vulcanized ink with special properties that are compatible with the treatment process.
Chloride ions are widespread, such as salt, soil, and so on. 304 stainless steel sheet corrodes quickly in the presence of chloride ions, even exceeding that of ordinary low carbon steel. Therefore, there are requirements for the use environment of 304 stainless steel sheet, and it needs to be wiped frequently to remove dust and keep it clean and dry.
Solution treatment: The alloying elements are not dissolved into the matrix, resulting in low alloy content in the matrix structure of the 304 stainless steel sheet and poor corrosion resistance.
Intergranular corrosion: This material that does not contain titanium and niobium tends to intergranular corrosion. Adding titanium and niobium, together with stabilization treatment, can reduce the intergranular corrosion of 304 stainless steel sheets.
