About 318 Stainless Steel
Corrosion Resistance: 318 stainless steel is known for its
excellent corrosion resistance in highly corrosive environments,
including acidic and alkaline environments. It is resistant to
corrosion from chemicals, solvents, and salts.
Strength: 318 stainless steel has higher strength compared to other
austenitic stainless steels such as 304 and 316. It has a minimum
tensile strength of 620 MPa and a minimum yield strength of 275
MPa.
Weldability: 318 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.
Ductility: 318 stainless steel has good 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.
Magnetic Properties: 318 stainless steel is non-magnetic in the
annealed condition but may become slightly magnetic after cold
working.
Heat Resistance: 318 stainless steel has excellent heat resistance
up to 925°C (1700°F). It can be used in high-temperature
applications such as furnace parts, heat exchangers, and exhaust
systems.
