321 stainless steel is a Ni-Cr-Ti type austenitic stainless steel with abrasion resistance, high temperature resistance, creep resistance, etc. It is used to manufacture wear-resistant acid containers and linings and pipelines of wear-resistant equipment.
321 stainless steel is a Ni-Cr-Ti type austenitic stainless steel. Its properties are very similar to 304, but due to the addition of metallic titanium, it has better resistance to grain boundary corrosion and high temperature strength. The addition of metallic titanium effectively controls the formation of chromium carbide.

Oil and gas industry:321 stainless steel pipesare often used in the manufacture of transmission pipelines, oil well pipes, valves, etc., and can work in high-temperature and highly corrosive environments.
Chemical plants and fertilizer plants: Using 321 stainless steel pipes in chemical processing equipment ensures the durability of the equipment, especially when handling highly corrosive chemicals.
High-Temperature Furnace Coal Refining Industry:321 stainless steel pipesare used to manufacture flue gas exhaust pipes and heat exchangers because they can maintain their structure and function under extreme high-temperature conditions.
Food and Pharmaceutical Industries: 321 stainless steel pipe is used for fluid transfer and storage due to its corrosion-resistant and non-reactive properties, as well as applications in food processing and pharmaceutical production facilities.
Construction and decoration industry: 321 stainless steel pipe can be used in various construction and decoration projects, such as railings, stair handrails, or outdoor furniture, to provide beautiful and long-lasting use.
The manufacturing process of stainless steel and alloys involves multiple steps to transform raw materials into flat,rectangular sheets or plates made of stainless steel and alloys. Here are a few key steps for stainless steel and alloys:
Molten stainless steel and alloys are cast into large ingots or billets through a casting process.
During the hot rolling process,the thickness of the steel ingot is gradually reduced and elongated to form long strips or coils.
Annealing involves heating stainless steel and alloys to a specific temperature and then slowly cooling it.
Cold rolling is carried out through rolling mills to reduce thickness to meet customer specifications.
