Features: 304 stainless steel is the most widely used kind of
chrome-nickel stainless steel, as a kind of steel with a wide range
of USES, has a good corrosion resistance, heat resistance, low
temperature strength and mechanical characteristics;Stamping,
bending and other thermal processing, no heat treatment hardening
phenomenon (temperature -196ºC~800ºC)..Corrosion resistance in the
atmosphere, if it is industrial atmosphere or heavily polluted
areas, the need for timely cleaning to avoid corrosion.Suitable for
food processing, storage and transportation.It has good
machinability and weldability.Plate heat exchanger, corrugated
pipe, household goods (1 or 2 types of tableware, cabinets, indoor
pipelines, water heaters, boilers, bathtubs), auto parts
(windshield wipers, mufflers, molded products), medical appliances,
building materials, chemicals, food industry, agriculture, ship
parts, etc.304 stainless steel is food grade stainless steel
approved by the state.
