What is 304 / 304L?
304 is the grade most stainless steel work starts from, and it is the right answer for the majority of atmospheric, water and food-contact service. The L variant caps carbon at 0.03% to prevent chromium carbide precipitation at grain boundaries during welding, which is what causes weld decay in heavier sections. Where chlorides are present, 304 pits, and the conversation should move to 316.
Designations
Stainless Steel 304 and 304L is also designated UNS S30400 / S30403, EN 1.4301 / 1.4306, AISI 304 / 304L, JIS SUS304 / SUS304L, GB S30408 / S30403 and Werkstoff X5CrNi18-9 / X2CrNi19-11. Quote the designation your specification uses and we will supply to it.
Why choose 304 / 304L round Bars
Widest availability and shortest lead time of any stainless grade, Excellent formability and weldability, Good resistance to atmospheric and fresh-water corrosion and Food-contact and potable-water approved. It is non-magnetic, with excellent weldability and fair machinability, and is used in continuous service in air up to about 870 °C.
Limitations to specify around
Pits in chloride environments, including coastal air and seawater, Not suitable for sulphuric, hydrochloric or reducing acid service, Work-hardens rapidly, which makes heavy machining slow and Non-L variant risks sensitisation in welded sections above 6 mm. We state these plainly so the grade is chosen for the right service.
