Alloy Grade Selection Guide: SS 405 vs SS 410 vs SS 410S vs SS 415
SS 405 Pipes & Tubes – Non-Hardening Ferritic Alloy
Formulated with an aluminum addition (0.10–0.30%), Stainless Steel Grade 405 Pipes prevent air-hardening when cooling from elevated temperatures. This suppressed transformation makes SUS 405 tubing an exceptional choice for refinery annealing boxes, furnace linings, and quenching racks exposed to thermal cycling.
SS 410 Pipes & Tubes – General Purpose Martensitic Strength
Featuring a 12% chromium matrix, Stainless Steel Grade 410 Pipes can be quenched and tempered to achieve high tensile strength and Rockwell hardness. SUS 410 tubing resists atmospheric corrosion and mild chemical media, making it ideal for high-stress pump shafts, valve trim, and steam turbine components.
SS 410S Pipes & Tubes – Low-Carbon Weldable Variant
Restricting carbon content to a maximum of 0.08%, Stainless Steel Grade 410S Pipes prevent martensite formation during welding, eliminating heat-affected zone (HAZ) cracking. SUS 410S tubes excel in continuous automated welding lines, oil refinery fractionating trays, and vessel linings where post-weld heat treatment is unfeasible.
SS 415 Pipes & Tubes – Super-Martensitic High-Toughness Grade
Enriched with nickel (3.5–5.5%) and molybdenum (0.3–1.0%), Stainless Steel Grade 415 Pipes (UNS S41500 / F6NM) offer exceptional impact energy absorption at sub-zero temperatures. EN 1.4000 series variants provide excellent resistance to sulfide stress cracking (H2S) and cavitation-erosion in hydro-turbine units and offshore oilfield piping.
