Stainless Steel – Austenitic – 1.4307 (304l) Bar And Section

Steel with slightly worse corrosion resistance than AISI 304 / 1.4301 because of relatively excessive carbon content. 304 / 304L stainless steel is resistant towards atmospheric corrosion and can be utilized in moderately oxidation and reduction environments. This alloy has excellent resistance against intergranular corrosion in its welded state and has great energy hand toughness at cryogenic temperatures. The lower carbon content minimizes carbide precipitation on account of warmth input, for instance throughout welding, giving improved resistance in opposition to intergranular corrosion.

Their nicely-balanced material properties make them appropriate for the fabrication of many merchandise. Fusion welding performance for kind 304 chrome steel is great each with and without fillers. Recommended filler rods and electrodes for chrome steel 304 is grade 308 chrome steel. Grade 321 may be used if post-weld heat remedy is not possible. View our full 304L stainless steel vary, from stainless steel 304L pipes and stainless-steel 304L profiles to stainless-steel 304L rods and chrome steel 304L seamless pipes.

Corrosion Resistance

• In addition, the 18/eight Cr-Ni grades are susceptible to mechanical sawing, water cutting and all forms of thermal cutting (plasma and laser).
• Acid resistant chrome steel with the addition of nitrogen, reduced carbon content material and elevated chromium 18-20% and nickel 10-12%.
• Otherwise, the improved version of grade 1.4307 / AISI 304L. Used where regular 304 or 304L materials just isn’t adequate and increased corrosion resistance is required.

X5CrNi18-10 and S30400 metal is a mass-produced grade, appearing in most types of semi-completed products, ranging from pipes, sheets, bars, profiles or strips. Due to its low carbon content material, the chance of sensitisation for intergranular corrosion after welding sheets up to 6 mm thick is strongly decreased when in comparison with other austenitic CrNi requirements grades with normal carbon content. The austenitic CrNi standard grades are essentially the most broadly used group of stainless steels.

General Characteristics

Stainless metal 304 / stainless-steel 304L is non-magnetic in its annealed state, but may become barely magnetic on account of chilly processing or welding. It is straightforward to weld and course of using commonplace manufacturing techniques. 304L is often doubly licensed as 304 and 304L The low carbon content of stainless-steel 304L combined with the addition of nitrogen makes it possible for 304L to fulfill the mechanical property requirements of 304.

It’s suitable for all kinds of functions that require good formability and weldability, and may be delivered with quite a lot of surface finishes. in the welded circumstances, 1.4307 ought to rather be specified if welding of bigger sections is required and no resolution annealing therapy after welding can be carried out. Surface conditions performs an necessary role within the corrosion resistance of this metal with polished surfaces exhibiting far superior corrosion resistance in contrast with rougher surfaces on the same materials.

1.4307 / AISI 304 L is an austenitic chromium-nickel stainless-steel with a low carbon content. Fabrication methods A240 304L Stainless steel plate, like forging, that involve sizzling working should happen after uniform heating to °C.
