Stainless Steel – Austenitic – 1.4307 (304l) Bar And Section
Steel with slightly worse corrosion resistance than AISI 304 / 1.4301 because of comparatively excessive carbon content. 304 / 304L chrome steel is resistant in opposition to atmospheric corrosion and can be used in moderately oxidation and reduction environments. This alloy has excellent resistance in opposition to intergranular corrosion in its welded state and has great energy hand toughness at cryogenic temperatures. The lower carbon content minimizes carbide precipitation as a result of heat enter, for instance throughout welding, giving improved resistance in opposition to intergranular corrosion.
Their well-balanced materials properties make them appropriate for the fabrication of many products. Fusion welding efficiency for sort 304 chrome steel is great both with and without fillers. Recommended filler rods and electrodes for chrome steel 304 is grade 308 stainless-steel. Grade 321 could also be used if post-weld warmth therapy is not potential. View our full 304L stainless steel vary, from stainless steel 304L pipes and stainless steel 304L profiles to chrome steel 304L rods and stainless steel 304L seamless pipes.
- In addition, the 18/8 Cr-Ni grades are prone to mechanical sawing, water slicing and all types of thermal slicing (plasma and laser).
- Acid resistant stainless-steel with the addition of nitrogen, decreased carbon content and elevated chromium 18-20% and nickel 10-12%.
- Over time, years of expertise and apply, many types of modified 304 steel have been developed, with restricted carbon content and even elevated or decreased content material of nickel, chromium, sulphur and phosphorus, such as 1.4305, 1.4306, 1.4307 and 1.4310.
- Otherwise, the improved version of grade 1.4307 / AISI 304L. Used where regular 304 or 304L materials isn’t sufficient and increased corrosion resistance is required.
X5CrNi18-10 and S30400 steel 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, the danger of sensitisation for intergranular corrosion after welding sheets as much as 6 mm thick is strongly reduced when in comparison with other austenitic CrNi standards grades with regular carbon content. The austenitic CrNi normal grades are essentially the most broadly used group of stainless steels.

Stainless steel 304 / chrome steel 304L is non-magnetic in its annealed state, but could turn into barely magnetic on account of cold processing or welding. It is straightforward to weld and process using commonplace manufacturing techniques. 304L is commonly doubly licensed as 304 and 304L The low carbon content of chrome steel 304L mixed with the addition of nitrogen makes it possible for 304L to fulfill the mechanical property requirements of 304.
It’s suitable for a wide variety of applications that require good formability and weldability, and may be delivered with a wide range of surface finishes. in the welded conditions, 1.4307 ought to rather be specified if welding of bigger sections is required and no resolution annealing remedy after welding may be carried out. Surface circumstances plays an necessary role within the corrosion resistance of this steel with polished surfaces exhibiting far superior corrosion resistance compared with rougher surfaces on the identical materials.
1.4307 / AISI 304 L is an austenitic chromium-nickel stainless-steel with a low carbon content material. Fabrication strategies A240 304L Stainless steel plate, like forging, that involve hot working should happen after uniform heating to °C.
