Astm A335 GR.P91 Steel Pripe Plipe pamtengo pa Tonni
Timapereka mitundu yosiyanasiyana ya Astm A335 P9 Anoy shalve zitsulo zosasangalatsa pogwiritsa ntchito zida zapamwamba kwambiri. Izi alloy steel p9 raw mabatani amapangidwa pakati pa 2250¡f \ / 1750¡c (1230¡c) kwa mphindi 30 Awa ndi mapaipi omwe amapangidwa pamtengo wapadziko lonse lapansi. Izi zaphokoso p9 Mapaipi osawoneka bwino amapezekanso mosiyanasiyana, magiredi, makulidwe, makulidwe malinga ndi zomwe makasitomala amafuna.
Kulankhula mosamalitsa, zitsulo zilizonse ndi cholocha, koma sikuti zipewa zonse zimatchedwa "alloy zitsulo". Zitsulo zosavuta kwambiri ndi chitsulo (chomata) ndi kaboni (c) (pafupifupi 0.1% mpaka 1%, kutengera mtundu) ndi osazindikira kudzera zodetsa); Izi zimatchedwa masitepe a kaboni. Komabe, mawu oti "alloy chitsulo" ndiye mawu okhazikika ponena za zitsulo ndi zinthu zina zoyatsira zopangidwa mwadala kuphatikiza kaboni. Malonda wamba amaphatikizapo Manganese (chofala kwambiri), nickel, chromium, molybdenum, vadicon, ndi a Boron. Malonda ochepa amaphatikizapo aluminium, cobat, mkuwa, Cehium, natani, kugwedeza, ndi zirkenium.
Matumba achitsulo a Asm A335 Chitoliro chachitsulo chimadziwika kuti chitoliro cha chrome molybdenum chitoliro ndi zinthu za mankhwala molybdenum ndi chromium. Molybdenum amatha kusintha zinthu zopanga zitsulo monga mphamvu, zotanuka, kuvala kukana, kukana ndi mphamvu.
