431. Acciaio con massiccia presenza di piombo e zolfo che aiuta le lavorazioni meccaniche (fresature, torniture ecc) senza influire nelle caratteristiche meccaniche. Acciaio martensitico temprabile con buona resistenza a corrosione. Idoneo per costruzione valvole, alberi per pompe e porta elica. Stato di fornitura: bonificato. Gamma: tondi. C. Si.
AISI 431 stainless steel is a martensitic stainless steel formulated for primary forming into wrought products. 431 is the AISI designation for this material. S43100 is the UNS number. Additionally, the British Standard (BS) designation is 431S29. It can have a moderately high tensile strength among the wrought martensitic stainless steels in
AISI 431 bead-on-plates were deposited on AISI 1010 by laser cladding, since it is a well-known corrosion-resistant material. The effects of laser power, scanning speed, powder feed rate and focal distance on the coatings' geometry and dilution ratios, as well as microstructure evolution, iron dilution and microhardness of the beads were …
