304 stainless steel (coil) plate

Source:Wuxi Xinzheng Special Steel   DateTime:2018-09-18

  304 stainless steel roll plate is divided into austenite stainless steel cold roll and stainless steel hot roll.

  304 stainless steel (coil) plate features: beautiful surface, diversified use possibilities;

  Good corrosion resistance;

  Longer than ordinary steel;

  Good corrosion resistance;

  High temperature oxidation resistance and high strength, therefore, fire resistance;

  Good plastic, good welding performance.

  It has good corrosion resistance, corrosion resistance and processing performance.

  304 stainless steel is the most widely used chrome-nickel stainless steel. As a kind of widely used steel, it has good corrosion resistance, heat resistance, low temperature strength and mechanical properties.

  Punching, bending, such as hot workability is good, no heat treatment hardening phenomenon (using the temperature to 196 ℃ ~ 800 ℃).

  Corrosion resistance in the atmosphere, if it is industrial atmosphere or heavily polluted areas, it needs timely cleaning to avoid corrosion.

  Suitable for food processing, storage and transportation.

  Good processing performance and weldability.

  Plate heat exchanger, corrugated pipe, household goods (1, 2 kinds of tableware, cabinets, indoor pipeline, water heater, boiler, bath), auto parts () windshield wiper, muffler, molded products, medical appliances, building materials, chemical, food industry, agriculture, Marine parts, etc.

  304 stainless steel is food grade stainless steel recognized by the state.
