Applications
- AISI 302 (1.4319, S30200) stainless steel is one kind of chrome-nickel stainless and heat-resisting steels. AISI 302 stainless steel is non-magnetic, extremely tough and ductile. Therefore, AISI 302 stainless steel is suitable in light industry, heavy industry, daily necessities and the decoration industry.

Heat treatment
AISI 302 annealing temperature is 1010-1120 degree Celsius , recommended temperature is 1400 degree Celsius
Oven stress-relief temperature and time for wire: 345 degree Celsius, 30 minutes.
Typical stress relief temperature for SS302 steel spring wire: 425-480 degree Celsius based on 30 min at temperature, only suitable for stress relief after coiling and not valid for stress relieving after shot peening. When the spring is to be used at a high temperature, the stress relief temperature should be close to the upper limit of this range to minimize relaxation in use. Otherwise, lower temperature are better.
AISI 302 typical forging temperature range is 925-1260 degree Celsius
