Introduction

Stainless steel surface by a chemical or electrochemical method for forming an oxide film in a specific solution, the oxide film of different thickness because visible light dry Browse behavior can get different colors. In this color processing, stainless steel can get a variety of colors. Fresh colored stainless steel color Yan, elegant appearance, commonly used in construction and decoration, hardware accessories and solar absorbers and other industries. Chemical method generally refers to stainless steel was immersed in an aqueous solution containing a specific coloring process chemicals carried in the process of generation of INCO table. Chemical method is not affected by the shape of the workpiece, and uniform coloring color, is the most commonly used stainless steel industrial coloring. Chemical coloring Quality also depends on the stability of stainless steel grades, surface condition of the workpiece and the colored liquid process conditions. Color reproducibility by the Color potential of control. Advantages electrochemical method is the color of good controllability and reproducibility, little affected by the surface condition of stainless steel, and low processing temperature. because This, and its industrial application gradually attention. Austenitic stainless steel suitable for chemical coloring, after coloring can get a satisfactory color appearance and good corrosion resistance; due to the ferritic Stainless steel corrosion tendency in coloring solution, was inferior to austenitic stainless steel bright color; the corrosion resistance of low chromium high carbon martensitic stainless steel Can poor, you can only get dark color, or to obtain a black surface. Stainless steel surface oxidation coloring Technical specifications and test methods Warning. This standard requires some substances and/or processes used, if appropriate measures are not taken, would be a health hazard. This standard We did not discuss any health hazards, safety or environmental matters and the use of standard regulations involved in the process. Producers, demand-side and/or standards to make With those who are responsible for establishing appropriate health, safety and environmental regulations and to take appropriate measures to comply with national, local and/or international laws and regulations Regulatory requirements. Compliance with this standard does not mean immunity from legal obligations.

1 Scope

This standard specifies the technical requirements, test methods and inspection rules of the stainless steel surface oxidation coloring. This standard applies to chemical or electrochemical oxidation colored stainless steel sheet, profiles and the workpiece, the high temperature oxidation of stainless steel You can also refer to the use of color. This standard does not apply to the use of other means of colored stainless steel, such as ion deposition, vapor deposition, organic coating and the like.
