GENERAL PROPERTIES
Stainless steel grade 301 is a commonly available austenitic stainless with good corrosion resistance and elevated carbon to allow for cold working to a variety of tempers. It can be obtained in the 1/4 hard, 1/2 hard, and full hard.
Specifications: S30100
APPLICATIONS:
High strength and excellent corrosion resistance make Type 301 Stainless Steel useful for a wide variety of applications. Typical uses include:
aircraft structural parts
trailer bodies
utensils
architectural and automotive rim
roof drainage products
conveyor belts
variety of industrial applications.
STANDARDS:
ASTM/ASME: UNS S30200
EURONORM: X 12 CrNi 17 7
DIN: 1.4310
RESISTANCE
CORROSION RESISTANCE
Good resistance in applications involving external exposure to mildly corrosive conditions at ambient temperatures.
Resists outdoor, industrial, marine, and mild chemical environments
susceptible to carbide precipitation during welding, which restricts its use in some applications
Similar to resistance of Stainless Steel grade 304
HEAT RESISTANCE
Can be exposed continuously without appreciable scaling to a max of 1600°F(871°C).
Maximum exposure temperature is about 1450°F (788°C), for intermittent exposure
Has an oxidation weight gain of 10mg/cm 2 in 1,000 hours, in temperatures over 1600°F (871°C).
