Properties and Applications of Each Grades

Austenitic steels
Grade Properties Applications
SUS303 Addition of Sulphur and Phosphor results in good heat and corrosion resistance, improves machinability Automatically machined parts, shafts, bolts, nuts, rivets, etc.
SUS304 Most versatile and most widely used stainless steel with good formability, corrosion resistance and weldability Food processing, chemical appara- tuses, nuclear power systems, semi- conductor manufacturing equipment
SUS304L Low carbon version of SUS304 with intergranular corrosion resistance. Suitable for areas where no heat can be applied after welding Chemical apparatuses, petroleum refining, paper manufacturing, etc.
SUS310S Good formability due to lower work hardening than SUS304. Also has oxidation and heat resistance. Combustion equipment, boilers, aircraft parts, cool rolling equipment, spinning , specialized drawing , etc.
SUS316 Adding molybdenum to SUS304 gives better overall corrosion resistant properties than SUS304. Low magnetization characteristics after machining. Various pitting corrosion resistant instruments, sea water pumps, piping members, boat components, valves, etc.
SUS316L Low carbon version of SUS316 with better intergranular corrosion resistance Petrochemistry devices, staining devices, textile machines, food preparation equipment
SUS317 Higher level of Molybdenum than SUS316 to increase corrosion resistance Chemical processing tubes operating in areas where acid resistance is required
SUS317L Low carbon version of SUS317 with better inter-granular corrosion resistance Chemical processing tubes operating in areas where acid resistance is required
SUS321 Titanium added to SUS304 to increase intergranular corrosion resistance and corrosion resistance Chemical, paper, dye, fertilizer industries
SUS347 Niobium (Nb) added to SUS304 to increase intergranular resistance Chemical, paper, dye, fertilizer industries
NCF600 Good high temperature properties such as heat resistance, corrosion resistance, and acid resistance Spacecraft, nuclear industry, components for industrial use turbines and assemblies, jet engines for aircraft
Austenitic ferritic steels
Grade Properties Applications
SUS329J4L Good pitting corrosion resistance and stress corrosion cracking resistance (SCC) under highly-concentrated chloride situations such as sea water Sea water heat exchangers, salt works, etc.
Precipitation hardening steel
Grade Properties Applications
SUS631 Addition of Aluminium (Al) results in precipitation hardening Springs, steel belts, washers, measuring instruments components
Titanium
Grade Properties Applications
TTP340C Good corrosion resistance, particularly seawater resistance Equipment and tools for chemical, petroleum refining, pulp paper industries
TTP340WC Good corrosion resistance, particularly seawater resistance Equipment and tools for chemical, petroleum refining, pulp paper industries
