303 stainless steel (UNS S30303) is a non-magnetic, austenitic, free-machining stainless steel product. This product is slightly modified based on the stainless steel product based on 10% chromium and 8% nickel. It has stronger machinability. Good mechanical and corrosion-resistant properties are also maintained. Delivery status: Generally delivered in heat treatment status.

303 stainless steel (UNS S30303)is used in petroleum, electronics, chemical industry, medicine, textile, food, machinery, construction, nuclear power, aerospace, military industry, and other industries. 303303 stainless steel is a free-cutting stainless steel containing sulfur and selenium respectively. It is used in situations where easy cutting and high surface brightness are mainly required. 303 stainless steel improves cutting performance and high-temperature resistance bonding performance. Best for automatic lathes, bolts, and nuts.
S30300 stainless steelis widely used in the chemical industry, food, medical equipment, and other fields. For example, in the chemical industry, this material can be used to make equipment such as transportation pipes and reactors; in the food field, it can be used to make storage tanks, cooking utensils, and other equipment; in the field of medical equipment, it can be used to make surgical instruments, Implants, and other products.
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.
