Look!National standard chemical composition of SUS420F stainless steel

Material name: Martensitic stainless steel

Brand: SUS420F

Standard: JIS (G 4303 steel bar)

●SUS420F features and applications:

SUS420 "cutting grade" martensitic steel, the earliest stainless steel similar to Brinell high chromium steel. Also used in surgical knives, can do very bright. SUS420F (13Cr-0.3C-High S) is a steel grade that improves the free cutting performance of SUS420J2 steel. SUS420F corresponds to Chinese GB Y3Cr13.

Executive standards: UNS N06625, SME SB–443, STM B443, MS 5599, DIN/EN2.4856, JIS G4902, NCF 625

Supporting welding consumables: welding rod grade lloy112, standard WS 5.11 (ENiCrMo-3). Welding wire grade lloy625, standard WS 5.14 (ERNiCrMo-3).

Performance characteristics: Excellent resistance to pitting corrosion, crevice corrosion, intergranular corrosion and erosion Resistance to inorganic acids such as phosphoric acid, sulfuric acid, etc. Also has alkali and organic acid corrosion resistance in oxidizing and reducing environments

Fields of application: Components of organic chemical process processes containing chlorides, especially where acid chloride catalysts are used, manufacture of digesters and bleaching tanks in the pulp and paper industry, absorption towers, reheaters, flue gas desulfurization systems in flue gas desulfurization systems Gas inlet baffles, fans (humid), agitator baffles and flues, etc., equipment and components used in acidic gas environments, acetic anhydride reaction generators, and sulfuric acid condensers.

Heat Treatment: High-quality properties can be achieved without heat treatment
