alloy karfe buty pipe pipe p12 bututu Astm A335 A cikin hannun jari
Abubuwan da ke ciki na A335 abu ya ƙunshi carbon, manganese, phosphorus, sulhium, molybdenum, comlel, aluminum, aluminum, titanium da kuma zirconia. Akwai nau'ikan bututu guda biyu da kuma bututu mai welded. An zana bututu mai laushi daga albarkatun ƙasa guda ɗaya, yayin da ASM A335 Gr P91 DID PE1 Belded bututun mai da aka welded daga tsiri ko takardar. Welding na iya zama Helical ko mai nisa daga wannan ƙarshen zuwa ɗayan don samar da bututun. Thearancin ya ba da ƙarfin ƙarfin bututu na bututu shine 415pta kuma mafi karancin ƙarfin tensile shine 585psa.
Sakamakon sunadarai na molybdenum (mo) da Chromium (cr), ana kiransa A335 yayin da ake magana a kai kamar yadda Chromium Moolybdenum bututu. Molybdenum yana ƙara ƙarfin ƙarfe da kuma iyaka na roba, sanye da juriya, ingancin tasiri da ƙarfi. Molybdenum yana ƙaruwa zuwa juriya ga mai laushi, yana hana ci gaban hatsi, kuma yana sanya Chromium Karfe ƙasa mai saukin kamuwa. Molybdenum shine mafi inganci sau ɗaya don inganta ƙarfin zazzabi na zazzabi. Hakanan inganta juriya daga lalata ƙarfe da kuma hana ciwon lalata. Chromium (ko Chrome) shine ainihin bangaren ƙarfe na bakin karfe. Duk wani karfe tare da 12% ko fiye chromium ana ganin bakin karfe. Chromium kusan ba a iya amfani dashi ba dangane da juriya ga tsayayya ga hadawa da hadawa a tsananin yanayin zafi. Chromumum yana ƙaruwa da tensile, yawan amfanin ƙasa da ƙarfi a ɗakin zazzabi.
Alloy da bututun ƙarfe na bakin karfe suna da kyau don aikace-aikacen masu inganci, waɗanda aka zaɓa don tsadar su, da machinble, da kuma jingin jiki masu lalata. Muna samarwa kayan don masana'antu daban-daban kamar: sarrafa abinci, makamashi, gyara tsiro, da mai binciken mai da gas.
