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.
