304 is a universal stainless steel, which contains more than 18% chromium and more than 8% nickel, and its density is 7.93 g/cm³。
Characteristic:
It has good corrosion resistance, heat resistance (service temperature: -196 ℃~ 800 ℃), low temperature strength and mechanical properties. Its stamping, bending and other hot workability is good, no heat treatment hardening phenomenon. It has good processability and weldability.
Application:
It is widely used in industry and furniture decoration industry (for making curtain walls, side walls, roofs and other building purposes)And food medical industry, suitable for food processing, storage and transportation.
Marking method:
The common marking methods are 06Cr19Ni10 and SUS 304, in which 06Cr19Ni10 generally refers to production under national standard, ASTM 304 refers to production under American standard, and SUS 304 refers to production under Japanese standard.
Processing method
Etching
The stainless steel surface is covered with a layer of screen printed acid resistant protective film, and then etched with ferrous chloride solution to draw the desired artistic pattern.
Color spraying
After screen printing, the pigment particles are sprayed to form a pear skin like surface to shape the desired artistic pattern.
