JIS G4304/4312 SUS 304 Stainless steel

JIS G4304/4312 SUS 304 is a common type of stainless steel, also known as "18-8" stainless steel because it contains approximately 18% chromium (Cr) and 8% nickel (Ni). This stainless steel has excellent corrosion resistance, workability and weldability, and is widely used in various industrial fields.

JIS G4304/4312 SUS 304 Stainless steel features:

Excellent corrosion resistance: Due to the high content of chromium, JIS G4304/4312 SUS 304 stainless steel has excellent corrosion resistance, especially in terms of oxidation resistance, acid resistance, resistance to pore corrosion and atmospheric crevices corrosion.

Good workability: This stainless steel material has good cold workability and weldability, which can meet a variety of complex processing needs.

High and low temperature performance: JIS G4304/4312 SUS 304 can maintain good heat resistance and strength at both high and extremely low temperatures, with excellent high temperature strength, high temperature oxidation and low temperature toughness.

The main chemical composition of JIS G4304/4312 SUS 304 includes iron, chromium, nickel and other elements, of which chromium content accounts for about 18% and nickel content accounts for about 8%. In addition, small amounts of carbon, silicon, manganese, phosphorus, sulfur and other elements may be included to meet their specific physical and chemical properties requirements.

JIS G4304/4312 SUS 304 is usually delivered in hot or cold rolled condition. Depending on the specific production standards and customer requirements, annealing, pickling or other surface treatments may also be required.

Due to its excellent corrosion resistance and processability, JIS G4304/4312 SUS 304 is widely used in many fields. For example, it can be used to make corrosion-resistant and formable equipment and parts, such as kitchenware, medical equipment, chemical equipment, building components, etc. In addition, due to its good heat resistance, it is also used to make parts in high temperature environments, such as automobile exhaust pipes, boilers, etc.
