Stainless Steel Wire: Specifications & Parameters
Alloy Series & Primary Grades
Grade / UNSSeries / TypeKey CharacteristicsTypical Applications
302 / S30200Austenitic (Cr-Ni)General-purpose, good corrosion
resistance, high strength
General engineering wire, springs, fasteners
302HQ / S30430Austenitic (Cr-Ni-Cu)Optimized for cold heading, low work hardeningFasteners, screws, bolts
303 / S30300Austenitic (free-machining)Contains sulfur for improved machinabilityMachined components, shafts, fittings
304 / S30400Austenitic (Cr-Ni)Most widely used, excellent mechanical properties and corrosion resistanceGeneral engineering, springs, mesh, fasteners, welding wire
304L / S30403Austenitic (low carbon)Lower carbon content (≤0.03%) for improved intergranular corrosion resistanceWelding applications, heavy-gauge sections, corrosive environments
310S / S31008Austenitic (high Cr-Ni)Excellent heat resistance and corrosion resistanceHigh-temperature applications, furnace components
316 / S31600Austenitic (Cr-Ni-Mo)Molybdenum addition for superior corrosion resistance, good creep strength at high temperaturesMarine, chemical, medical, high-corrosion environments
316L / S31603Austenitic (low carbon)Low carbon version of 316, excellent intergranular corrosion resistanceWelding, pharmaceutical, marine
321 / S32100Austenitic (stabilized)Titanium addition for stabilization against intergranular corrosionHigh-temperature service, exhaust systems
347 / S34700Austenitic (stabilized)Niobium/columbium stabilizationHigh-temperature, corrosive service
410 / S41000Martensitic (Cr)Magnetic, hardenable by heat treatment, moderate corrosion resistanceFasteners, valve parts, springs, cutlery
416 / S41600Martensitic (free-machining)Contains sulfur, high machinabilityMachined parts, shafts
430 / S43000Ferritic (Cr)Magnetic, good corrosion resistance, lower cost than austenitic gradesAppliances, architectural trim, automotive
431 / S43100Martensitic (high Cr-Ni)Very high tensile strength, good corrosion resistanceHigh-strength shafts, marine components
