ASTM A240 SS304 STAINLESS STEEL PRECISION STEEL STRIP for Car Decorations
ASTM A240 SS304 stainless steel is the most widely used chromium-nickel stainless steel. As a widely used steel, it has good corrosion resistance, heat resistance, low-temperature strength and mechanical properties; it has good hot working properties such as stamping and bending.
Resistant to corrosion in the atmosphere, if it is an industrial atmosphere or a heavily polluted area, it needs to be cleaned in time to avoid corrosion. Suitable for food processing, storage and transportation. Good processing performance and weldability. Plate heat exchanger, bellows, household products (1 type, 2 types of tableware, cabinets, indoor plumbing, water heaters, boilers, bathtubs), automotive parts (windshield wipers, mufflers, molded products), medical equipment, building materials, chemical, food industry, agriculture, ship parts, agriculture, marine parts and so on.
