SS Round Rod 304 304l 316 316l 321 Stainless Steel Round Bar 8mm
Product Description
Equivalent to the domestic grade 0Cr18Ni10Ti 321 stainless steel is a Ni-Cr-Mo austenitic stainless steel, its performance is very similar to 304, but due to the addition of metallic titanium, it has better resistance to intergranular corrosion and high temperature strength. Due to the addition of titanium, it effectively controls the formation of chromium carbide. 321 austenitic stainless steel has good corrosion resistance in the atmosphere and is widely used in petrochemical, electric power, bridge and automobile industries [1]. However, the "stainlessness" of stainless steel is not absolute. Due to the special service environment, stainless steel will also corrode. Factors such as medium concentration, pH value, and temperature will have a greater impact on the corrosion resistance of stainless steel. For example, long-term use within the sensitization temperature range of 450 to 850°C will cause intergranular corrosion of stainless steel. The mechanism is that C combines with Cr at the grain boundary to form Cr23C6 and precipitate, which reduces the Cr content at the grain boundary. This is the so-called "chromium depletion". The Cr element is one of the main elements that inhibit intergranular corrosion. When the Cr content at the grain boundary is less than 12%, the probability of intergranular corrosion will increase.
