304 has a wide range of uses, with good corrosion resistance, heat resistance, low temperature strength and mechanical properties; good hot workability such as stamping and bending, no heat treatment hardening phenomenon (non-magnetic, use temperature -196°C~800°C).According to the manufacturing method, it is divided into two types: hot rolling and cold rolling. According to the structural characteristics of the steel type, it is divided into five categories: austenite, austenite-ferrite, ferrite, martensite, and precipitation hardening. It is required to withstand the corrosion of various acids such as oxalic acid, sulfuric acid-iron sulfate, nitric acid, nitric acid-hydrofluoric acid, sulfuric acid-copper sulfate, phosphoric acid, formic acid, acetic acid, etc.

  It is widely used in chemical industry, food, medicine, papermaking, petroleum, atomic energy, etc. Industry, as well as various parts and components of construction, kitchenware, tableware, vehicles, and household appliances.The stainless steel plate has a smooth surface, high plasticity, toughness and mechanical strength, and is resistant to corrosion by acids, alkaline gases, solutions and other media. It is an alloy steel that is not easy to rust, but it is not absolutely rust-free.
