What is ultra-low carbon stainless steel? Stainless steel plate manufacturer Shandong Baowu Steel Group tells you that ultra-low carbon stainless steel refers to austenitic stainless steel with a carbon content of less than 0.03% or ferritic stainless steel with a carbon content of less than 0.01%. corrosion susceptibility.
Has anyone told you what are the specific grades of ultra-low carbon stainless steel?
The above materials are specific grades of ultra-low carbon stainless steel. Please see the following for their characteristics and uses:
301L stainless steel (022Cr17Ni7), which is an ultra-low carbon steel of 301 stainless steel (12Cr17Ni7), has good intergranular corrosion resistance and weldability, and is used for railway vehicles.
304L stainless steel (022Cr19Ni10), steel with lower carbon content than 304 stainless steel (06Cr19Ni10), has superior resistance to intergranular corrosion, and does not undergo heat treatment after welding.
316L stainless steel (022Cr17Ni12M2), which is an ultra-low carbon steel of 316 stainless steel (0Cr17Ni12Mo2). Ultra-low carbon austenitic stainless steel has good corrosion resistance to various inorganic acids, alkalis, and salts (such as sulfuric acid, sulfuric acid, phosphoric acid, acetic acid, formic acid, chloride salts, halogens, sulfites, etc.). Due to the low carbon content, the coal joint performance is good, suitable for multi-layer welding, generally no heat treatment is required after coal, and there is no tendency of knife-edge corrosion after welding. It can be used in the manufacture of industrial equipment such as synthetic fibers, petrochemicals, textiles, fertilizers, printing and dyeing, and atomic energy, such as towers, tanks, containers, and pipelines.
904L stainless steel (015Cr21N26Mo5Cu2), high Mo stainless steel, fully resistant to sulfuric acid, phosphoric acid, acetic acid and other corrosion, and can solve the problems of chloride pitting corrosion, crevice corrosion and stress corrosion. It is mainly used for towers, tanks, tubes, heat exchangers, etc. in petrochemical, chemical, fertilizer, and ocean development.
317L stainless steel (022Cr19Ni13Mo3), which is an ultra-low carbon steel of 317 stainless steel (06Cr19Ni13Mo3), has better resistance to intergranular corrosion than 317 stainless steel (06Cr19Ni13Mo3), and is mainly used for condenser tubes in power stations.
SUH409L stainless steel (022Cr11Ti), ultra-low carbon steel, good welding performance, used for automotive exhaust treatment devices.
SUS410L stainless steel (022Cr12), good bending performance and processability of welding parts. It is mostly used in the container industry.
SUS436L stainless steel (019Cr18MoTi), adding Mo to the steel to improve the pitting corrosion resistance, crevice corrosion resistance and strength of the steel.
SUS430J1L stainless steel (019Cr18CuNb), ultra-low C, N control, added Nb, Cu, is a medium Cr ultra-pure ferritic stainless steel, with excellent surface quality and cold forming performance, used for exterior decoration parts of automobiles and buildings , home appliances, etc.
Note: The characteristics and uses of ultra-low carbon stainless steel such as 301L, 304L, 316L, 904L, 317L, SUH409L, SUS410L, SUS430J1L are all derived from the national standard “GB/TSUS436L, 3280-2015 Stainless Steel Cold-rolled Steel Sheet and Strip”, stainless steel plate Organized by the manufacturer Shandong Baowu Steel Group
