Austenitic stainless steel is the most suitable coloring material

Among the commonly used primary stainless steels, austenitic stainless steel is the most suitable coloring material to obtain a satisfactory color appearance.

Ferritic stainless steel does not produce as bright a color as the former due to the increased possibility of corrosion in the coloring solution.

Low chromium high carbon martensite stainless steel, due to its poor corrosion resistance, can only get a dark color or black surface.

According to the report, austenitic stainless steel after the use of low temperature surface oxidation treatment coloring method, exposed in the industrial atmosphere for 6 years, in the Marine atmosphere exposed for 1 and a half years, soaked in boiling water for 28 days, or heated to 300℃ or so, its color luster are no change.

In addition, it can also withstand the general mold processing, drawing and bending processing and work hardening.
