Stainless steel grade 301 is usually supplied in the form of strips and wires, with a tensile strength of up to 1800 Mpa, to produce tempers ranging from 1/16 Hard to Full Hard. By subjecting grade 301 to controlled analysis it is capable of retaining sufficient ductility even in ½ hard conditions. This form of grade 301 may be used in aircraft, rail car components and architectural structures. Tempers of this grade, ranging from ¾ to full hard, may be used in applications requiring high wear resistance and spring features with simple form designs.

Grade |
Reason for choosing the alternate grade |
|
304 |
The lower work hardening rate of 304 is acceptable, giving better ductility required for forming. |
|
316 |
A higher corrosion resistance is required, and the lower work hardening rate of 316 can be compensated for. |
Stainless steel grade 301 is subjected to solution treatment annealing in temperatures ranging from 1010oC to 1120°C followed by rapid cooling. For intermediate annealing a low temperature range is chosen. Thermal hardening does not suit this grade of stainless steel.
Stainless steel grade 301 and low carbon variants of this grade are predominantly used as high strength stainless steel. The work hardening rates of these grades are very high, in the range of a 14MPa increase per 1% reduction in area of cold work. As a result of this characteristic high strength can be achieved from cold rolling and roll forming operations.
Through such forming methods strain hardened austenite may be partially transformed to martensite. In spite of achieving such high strengths, the residual ductility in the alloy is capable of causing severe cold deformation. The alloy is non-magnetic in the annealed condition, but shows strong magnetism when cold worked.
Stainless steel grade 301 is suitable for all forms of standard welding methods. The use of grade 308L as filler metal is recommended. Welded parts in grade 301 must be subjected to annealing in order to attain maximum corrosion resistance. For grades 301L and 301LN annealing is not necessary after welding. The purpose of welding followed by annealing is to remove the high strength brought about by cold rolling.
The process of spot welding is used to assemble the cold rolled 301 components; this rapid welding technique does not hamper the overall strength of the component.
