304 Stainless Steel: Attributes
- Corrosion Resistance: 304 has excellent corrosion resistance in a wide range of atmospheric environments and when in contact with different corrosive substances.
- Heat Resistance: 304 has good resistance to oxidation and can be used at temperatures up to 870°C.
- Machinability: 304 has superior machinability giving higher machining rates and lower tool wear in many operations. 304 stainless can be machined, folded or roll-formed into a variety of components for applications.
- Weldability: Datum 304 stainless steel has excellent forming and welding characteristics both with and without fillers. Post-weld annealing is not required when welding thin sections.
- Hardness Range: 3370-410HV.
- Tensile: 1130 N/mm².

Datum FG 304 Stainless Steel is produced with the tightest thickness tolerance on the market, the same as our Datum PhD 304 Stainless Steel, and is available in gauges from 0.08mm to 0.25mm from stock and widths up to 610mm and any sheet length or coil.
Datum FG 304 Stainless Steel is perfectly suited to laser cutting and chemical etching. The fine grain structure of this material ensures that cut edges are clean and precise, with a wall finish that is smoother than standard 304 Stainless material. The images opposite show the effect of different annealing process when the material is half etched.
