305 Stainless Steel Supply

305 Stainless Steel Properties

Corrosion Resistance: 305 stainless steel is known for its excellent corrosion resistance in a wide range of environments, including acidic and alkaline environments. It is resistant to corrosion from chemicals, solvents, and salts.

Ductility: 305 stainless steel has high ductility, which means that it can be easily formed and shaped without cracking or breaking. This property makes it ideal for applications that require complex shapes or designs.

Strength: 305 stainless steel has moderate strength, making it suitable for applications that require moderate mechanical strength. It has a minimum tensile strength of 620 MPa and a minimum yield strength of 275 MPa.

Weldability: 305 stainless steel is known for its good weldability, making it a popular choice for welding, brazing, and soldering. It can be welded using common welding techniques, such as TIG, MIG, and stick welding.

Magnetic Properties: 305 stainless steel is non-magnetic in the annealed condition but may become slightly magnetic after cold working.

Heat Resistance: 305 stainless steel has good heat resistance up to 870°C (1600°F). It can be used in high-temperature applications such as furnace parts, heat exchangers, and exhaust systems.
