1. Stainless Steel 301 Pipe 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

2. Stainless Steel 301 Pipe 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).

3. Stainless Steel 301 Pipe 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.

4. Stainless Steel 301 Pipe 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.

5. Stainless Steel 301 Pipe Welding:

• must be annealed for maximum corrosion resistance
• more difficult to work than other austenitic stainless steels, due to its high work hardening rate..
• must be annealed for maximum corrosion resistance
• 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..
• material will lose temper in the heat affected weld zone.
