304

304 stainless steel is standard chrome 18 – nickel 8 Austenitic stainless steel, as the most familiar and most frequently used alloy in the stainless steel family.

304 contains both chromium (usually 18%) and nickel (usually 8%) metals as the main non-iron constituents, it is an Austenite steel, it has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, it is not very electrically or thermally conductive, and is non-magnetic, and has a higher corrosion resistance than regular steel.
