Possible Alternative Grades
A list of the possible alternatives to grade 301 stainless steels is given in Table 5.
Table 5 - Possible alternative grades to 301 grade stainless steel
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.
Corrosion Resistance
The resistance to corrosion offered by stainless steel grade 301 is similar to that offered by 304. This grade exhibits good resistance to corrosion in mildly corrosive environments at ambient temperatures.
Heat Resistance
Grade 301 exhibits good oxidation resistance for intermittent services up to 840°C and for continuous service up to 900°C.
Heat Treatment
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.
Cold Working
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.
Welding
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.
Applications
Some of the typical applications of grade 301 stainless steels are listed below:
- Making 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
