We use #304 and #306 grade stainless steel in our products. It contains a maximum of 0.15% carbon, a minimum of 18% chromium and sufficient nickel to retain an austenitic structure at all temperatures. Grade #304 and #306 is the most versatile and the most widely used of all stainless steels. Its chemical composition, mechanical properties, weld ability and corrosion resistance provide the best all-round performance stainless steel.
