06Cr19Ni10 Metal Wire Mesh Product Chemical Composition, Material Properties and Standards Introduction
06Cr19Ni10 is a high alloy steel that can resist corrosion in air or chemical corrosive media. 06Cr19Ni10 stainless steel is the 0Cr18Ni9 stainless steel wire mesh product in the old standard.

and performance
The mechanism of stainless steel rust prevention is that alloy elements form a dense oxide film, which isolates oxygen from contact and prevents further oxidation. Therefore, stainless steel is not "stainless".
The rust phenomenon of 06Cr19Ni10 material[2] may be caused by the following reasons:
1. Chloride ions exist in the use environment. Chloride ions are widely present, such as salt, sweat, sea water, sea breeze, soil, etc. Stainless steel corrodes very quickly in the environment where chloride ions exist, even more than ordinary low-carbon steel. Therefore, there are requirements for the use environment of stainless steel, and it needs to be wiped frequently to remove dust and keep it clean and dry. (In this way, it can be classified as "improper use".) There is an example in the United States: a company used an oak container to hold a solution containing chloride ions. The container has been used for nearly a hundred years. It was planned to be replaced in the 1990s. Because the oak material is not modern enough, the container leaked due to corrosion 16 days after it was replaced with stainless steel.
2. No solid solution treatment. The alloy elements are not dissolved into the matrix, resulting in a low alloy content in the matrix structure and poor corrosion resistance.
3. This material without titanium and niobium has a natural tendency to intergranular corrosion. Adding titanium and niobium, combined with stabilization treatment, can reduce intergranular corrosion. A high alloy steel that can resist corrosion in air or chemical corrosive media. Stainless steel has a beautiful surface and good corrosion resistance. It does not need to be treated by surface treatment such as color plating, but exerts the inherent surface properties of stainless steel. It is a kind of steel used in many aspects. It is usually called stainless steel. Representative performance includes 13 chromium steel, 18-8 chromium-nickel steel and other high alloy steels. From the perspective of metallography, because stainless steel contains chromium, a very thin chromium film is formed on the surface. This film isolates the oxygen invading from the steel and plays a role in corrosion resistance.
06Cr19Ni10 is a universal stainless steel. It is widely used in the manufacture of equipment and parts that require good comprehensive performance (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 12% chromium.
06Cr19Ni10 stainless steel is a grade of stainless steel produced according to the American ASTM standard.
06Cr19Ni10 is the most widely used stainless steel and heat-resistant steel. It is used for food production equipment, general chemical equipment, nuclear energy, etc.
06Cr19Ni10 stainless steel is the most widely used chromium-nickel stainless steel with good corrosion resistance, heat resistance, low temperature strength and mechanical properties. It is corrosion resistant in the atmosphere. If it is an industrial atmosphere or a heavily polluted area, it needs to be cleaned in time to avoid corrosion. It is suitable for food processing, storage and transportation. It has good processing performance and weldability.
