Description about 321/321H stainless steel and comparison with normal 304
Both 304 and 321 are 300 series stainless steels and they have little difference in corrosion resistance. However, in the heat-resistant conditions of 500-600 degrees Celsius, 321 material stainless steel is mostly used. In addition, a heat-resistant steel has been specially developed abroad and is called 321H. Its carbon content is slightly higher than that of 321, similar to domestic 1Cr18Ni9Ti. The appropriate amount of Ti is added to the stainless steel to improve its resistance to intergranular corrosion. This is due to the fact that in the early stage of stainless steel production, because the smelting technology was not high enough to reduce the carbon content in the steel, it was only possible to achieve this by adding other elements. With the advancement of technology, it has been possible to produce low-carbon and ultra-low-carbon stainless steel varieties. Therefore, 304 materials have been widely used. At this time, the characteristics of heat resistance of 321 or 321H or 1Cr18Ni9Ti are apparent.

304 is 0Cr18Ni9Ti, 321 is based on 304 plus Ti to improve the tendency of intergranular corrosion.

321 stainless steel in which Ti exists as a stabilizing element, but it is also a hot-strength steel species, is much better than 316L in high temperature. 321 stainless steel in organic acids of different concentrations, different temperatures, especially in the oxidizing medium Good abrasion resistance, used to make linings and conveying pipes for wear-resistant acid containers and wear-resistant equipment.

321 stainless steel is a Ni-Cr-Mo type austenitic stainless steel, its performance is very similar to 304, but due to the addition of metallic titanium, it has a better resistance to grain boundary corrosion and high temperature strength. Due to the addition of metallic titanium, it effectively controls the formation of chromium carbide.

321 stainless steel has excellent stress Rupture performance and high temperature resistance (Creep Resistance) stress mechanical properties are better than 304 stainless steel.
