2304 (UNS S32304) stainless steel is a duplex stainless steel composed of 23% chromium, 4% nickel and a small amount of other alloying elements, and does not contain molybdenum. This dual-phase structure gives it high strength and good corrosion resistance. Among them, austenite has good toughness and strength, while ferrite has good corrosion resistance. This dual-phase structure not only improves the material's mechanical properties, but also improves its corrosion resistance, giving it a longer service life in harsh environments.

2304 stainless steelis a duplex stainless steel with the following main uses:
Construction field: It can be used to manufacture structural parts such as bridges, high-rise buildings, and public facilities. Due to its high strength and excellent corrosion resistance, it can improve the safety and stability of the structure.
Chemical industry: used to manufacture equipment such as pipelines, storage tanks, and reactors. Due to its corrosion resistance and excellent high-temperature resistance, it can effectively improve the reliability and service life of the equipment.
Petroleum and marine industry: It can be used to manufacture equipment such as oil and gas pipelines, offshore platforms, and subsea pipelines. Due to its high strength and excellent corrosion resistance, it can effectively improve the safety and stability of the equipment.
Food processing and catering equipment: often used to make kitchen tableware and equipment, such as pots, bowls, plates, knives, etc., with good corrosion resistance and easy cleaning.
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.
