Steel Types	Properties and applications
SUS304	General-purpose stainless steel: Used to make general chemical equipment, food equipment and nuclear power equipment, and in construction and household supplies.
SUS304L	304 ultra-low carbon steel: More resistant to intergranular corrosion than 304. Used when heat-treatment after welding is not possible.
SUS316	Stainless steel made by adding molybdenum to 304 for improved corrosion resistance. Used in items such as ship parts.
SUS316L	316 ultra-low carbon steel: Has higher intergranular corrosion resistance. Used in areas requiring resistance to corrosion and pitting.
SUS317	Higher corrosion resistance than 316. Used to make equipment for applications such as papermaking and dyeing.
SUS317L	317 ultra-low carbon steel: Has higher intergranular corrosion resistance than 317.
SUS309S	Has higher corrosion resistance than 304. Used mainly as a heat-resistant steel.
SUS310S	Has higher oxidation resistance than 309. Used mainly as a heat-resistant steel.Hi
SUS321	Made by adding titanium to 304 to increase intergranular corrosion resistance.
High Nickel alloy	Has very high oxidation and heat resistance. Used in corrosive and high-temperature environments.
