S30400 steel sheet comprehensive information

1. Basic performance

Chemical composition: carbon (C) ≤ 0.08%, chromium (Cr) 18-20%, nickel (Ni) 8-10.5%, and containing elements such as manganese and silicon. Low carbon design reduces the risk of sensitization.

Corrosion resistance: Suitable for atmospheric, freshwater, and weak acid environments, but sensitive to intergranular corrosion (requires solution treatment or 304L version after welding).

Heat resistance: The working temperature range is -196 ° C to 800 ° C. Long term high temperature (425-860 ° C) may cause sensitization, and attention should be paid to antioxidant treatment.

Mechanical properties: non-magnetic in annealed state, weak magnetism may occur after cold processing; Combining high strength and toughness.

2. Processing and Supply

Processing technology:

Cold processing: Suitable for forming processes such as stretching, bending, and stamping, the surface of cold-rolled plates can achieve a 2B smoothness.

Hot processing: supports forging, hot rolling, etc., temperature control is required to avoid chromium carbide precipitation.

Welding: TIG/MIG welding is recommended, and solution treatment (especially for thick plates) is recommended after welding to reduce stress.

Specifications and Customization:

Common thickness: 0.5-100mm, width can reach 1500mm, surface treatment includes film sticking, flattening, slitting, etc.

Support non-standard customization, such as special requirements for wear resistance, high temperature resistance, etc.

3. Application Fields

Food and healthcare: food processing equipment, storage tanks, surgical instruments, etc. (compliant with food grade standards).

Industrial field: corrosion-resistant components such as chemical reactors, petroleum pipelines, and automotive exhaust systems.

Architectural Decoration: Scenes that combine aesthetics and durability, such as handrails, door and window accessories.
