Grade 301 / 301L Stainless Steel Strip Coil
Stainless steel grade 301 is typically supplied as strips and wires
with tensile strength up to 1800 MPa, available in tempers ranging
from 1/16 Hard to Full Hard. This grade maintains sufficient
ductility even in ½ hard conditions and is ideal for aircraft
components, rail car parts, and architectural structures. Higher
tempers (¾ to full hard) provide excellent wear resistance and
spring characteristics.
Grade 301L, the low-carbon variant, offers superior ductility,
while 301LN contains higher nitrogen content for increased work
hardening rates. Grade 301 is specified in ASTM A666, with 301L
represented by JIS G4305 and 301LN by EN10088-2 as grade 1.4318.

Performance Characteristics
Corrosion Resistance
Grade 301 offers corrosion resistance similar to 304 stainless
steel, providing good performance in mildly corrosive environments
at ambient temperatures.
Heat Resistance
Excellent oxidation resistance for intermittent service up to 840°C
and continuous service up to 900°C.
Heat Treatment
Solution treatment annealing at 1010°C to 1120°C followed by rapid
cooling. Intermediate annealing uses lower temperature ranges. Not
suitable for thermal hardening.
Cold Working
High work hardening rates (approximately 14MPa increase per 1%
reduction) enable achievement of high strength through cold rolling
and forming operations. Non-magnetic when annealed, becomes
magnetic when cold worked.
Welding
Suitable for all standard welding methods using 308L filler metal.
Annealing required after welding for maximum corrosion resistance
(not necessary for 301L/301LN). Spot welding preserves component
strength.
Applications
- Rail car structural components
- Air frame sections
- Highway trailer components
- Automotive wheel covers
- Wiper blade clips and holders
- Stove element clips
- Screen frames
- Toaster springs
- Curtain walls
