The performance of stainless steel plate introduced the knowledge 409

From the analysis of metallography, because the 409 stainless steel plate containing chromium and chromium film formed on the surface of thin film, the separated invasion and 430 stainless sheet in oxygen corrosion effect. In order to maintain the inherent in 409 stainless steel plate corrosion resistance steel must contain at least stainless steel plate  chromium. 409 stainless steel is one kind of universal, which is widely used in production requirements of good comprehensive performance (corrosion resistance and moldability) equipment and parts. 304 stainless steel plate is a brand produced in accordance with the standards of stainless steel. The equivalent of 409 stainless steel. The 409 nickel containing 9%. 409 is the most stainless steel iron  used stainless steel, heat-resistant steel. Used in food production equipment, chemical equipment and nuclear power.
