301 Stainless Plate

Gnee Stainless inventory now includes Alloy 301 (UNS S30100) in sheet and sheet coil with short delivery. This grade is inventoried in three conditions: 1/4 hard, 1/2 hard, Full hard.

Type 301 is an austenitic stainless steel with a nominal composition of 17 percent chromium and 7 percent nickel, which provides good strength and ductility when cold worked. 301 is well suited to welding, forming and drawing. It also has excellent corrosion resistance properties.

301 Stainless Plate 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).

PROCESSING HEAT TREATMENT

Solution Treatment (Annealing) – Heat to 1010-1120°C and cool rapidly.

Use low side of range for intermediate annealing.

This grade cannot be hardened by thermal treatment.

COLD WORKING

hardens at high rate, creating a very high strength from cold rolling and from roll forming.

more difficult to work than other austenitic stainless steels, due to its high work hardening rate.

strain-hardened austenitite steel undergoes partial transformation into martensitite steel during this process.

severe cold deformation can still occur, due to residual ductility.

Grade 301 becomes strongly magnetic when cold rolled

WELDING

Must be annealed for maximum corrosion resistance

Material will lose temper in the heat affected weld zone.

Welding and post weld annealing will both remove high strength induced by prior cold rolling.

Spot welding is commonly used to assemble cold rolled 301 components.
