Categories Characteristics
SUS304 7.93 205 or more 520 or more 40 or more Austenitic This is a typical type of steel made of austenitic stainless steel. We also use it for a wide variety of products.
SUS316 7.98 205 or more 520 or more 40 or more Austenitic Steel type excellent in heat resistance and corrosion resistance than SUS304. Use for products used in high-temperature environmental and corrosion environmental.
SUS316L 7.98 175 or more 480 or more 40 or more Austenitic Steel type with improved intergranular corrosion resistant comapred with SUS316. This is used for example to control sensitization.
SUS310S 7.98 205 or more 520 or more 40 or more Austenitic Steel type with excellent heat resistance and acid resistance. It is mainly used for wire conveyor belt related to heat treatment. ※2
AISI314 - - - - Austenitic This steel type has more oxidation resistance than SUS310S. On the other hand, resistance of intergranular corrosion or sigma-phase embrittlement is inferior. It is mainly used for wire conveyor belt related to heat treatment. ※2
SUS430 7.70 205 or more 450 or more 22 or more Ferritic This is common steel type among ferritic stainless steel. Although corrosion resistance is inferior to SUS304 above, it has strong magnetism.
