About 304 Stainless Steel
Grade 304 is the most commonly used stainless steel. It is an austenitic, corrosion-resistant steel with excellent strength, toughness, fabrication characteristics and weldability. The low carbon version, 304L, may be required for full corrosion resistance when thicker sections are welded. The 304H version has a guaranteed minimum carbon content, which ensures good strength at high temperatures.
Typical Applications
- Brewing and dairy equipment
- Evaporators, drums, barrels
- Heat exchangers
- Hospital equipment
- Refrigeration parts
- Chemical and food processing
- Shop fittings, bench tops, kitchens
- Kitchen utensils, sinks, wash troughs
- Hand rails, dishwashers, clothes dryers
- Ovens, heating trays, air conditioning equipment
- Guttering and rain water goods
- Counters and display cabinets
- Commercial oven hoods, beer barrels

Available Products
We can supply 304 stainless steel as plate, coil, sheet, strip, round, hexagon, flat bar, angles, tube, pipe and welding consumables.
Finishing Options
No1 (hot rolled, annealed and pickled), 2D (cold rolled), 2B (cold rolled, skin passed), N4 (polished), BA (bright annealed). Flat products are available surface protected with white polyethylene (PE) film. Protection with blue poly vinyl chloride (PVC) for deep drawing or black PVC (for heavy forming) is also available.
Corrosion Resistance
Grade 304 stainless steel has excellent corrosion resistance in many environments. It gives good service in atmospheric conditions, resisting most environments except for marine conditions, or where industrial pollution is heavy. Best appearance is maintained where the design allows even rain washing of the surface. It has given excellent service in some situations in potable water. Pitting and crevice corrosion may occur at higher chloride content, and 200 ppm is accepted as the upper limit. Grade 304 stainless steel is not generally used in seawater, due to the probability of crevice corrosion developing under sediments, precipitation and biofouling.
Applications
- Architecture & Building: Surface, Pillar, Window frame, Stair hand-rail
- Kitchen Utensils: Washing machine drum, Gas range stove, Plate, Housewares, Hollowware
- Others: Computer components, Automotive trim
