Better intergranular corrosion resistance than 316, can be used in very severe conditions, with less work hardeding, no-magnetic Sea water treatment equipments, chemical industry, dye making, paper mill, herb acid, fertilizer production equipments, photography, food processing industry, coastal installations SUS321 With the addition of Ti, thereby prevent intergranular corrosion. Heat- resistant, high-temperature resistant and antioxidizing in high- temperature Heat-resistant material,???? automobiles, aerocraft ventilation pipings, boiler cover, pipings, chemical devices and heat-exchanger SUS steel has lower Cr? Ni content than 304.lts strength increased by cold working Trains, aircraft, belt converyors, vehicles spring SUS301L 301L is made by lower carbon 301 type. Better intergranular corrosion resistance than 301, strength increased by cold working Frame of Trains, building exterior material
