Tili ndi dongosolo lokwanira lokwanira ndipo limatha kusintha bwino komanso kukulitsa mitundu yatsopano ya S30900 \ / S30908 309s Mtengo Wapakati Wapakati pa Makasitomala 309 Tikumanga mtundu watsopano wamabizinesi ndikuwongolera kwambiri ndipo tikuyembekeza kuchita mgwirizano ndi abwenzi kunyumba ndi kunja. Kampani yathu imatenga umisiriwu poyendetsa kulimbikitsa mwayi wachuma wa kampani yathu.
Chifukwa cha kupangidwa kwa mankhwala a molybdenum (mo) ndi chromium (cr), a335 nthawi zambiri amatchedwa chromium Molybdenum chubu. Molybdenum amawonjezera mphamvu ya chitsulo komanso malire, kuvala kukana, kumathandizira bwino komanso kuumitsa. Molybdenum akuwonjezeka kukana kuwononga, kumalepheretsa kukula kwa tirigu, ndikupangitsa kuti Chromium zikhale zopanda vuto. Molybdenum ndiye chowonjezera chochuluka kwambiri chowonjezera kutentha kwambiri. Zimawonjezeranso kukana kwa zitsulo za chitsulo ndipo chimalepheretsa kuponderezedwa. Chromium (kapena Chrome) ndiye gawo loyambirira la chitsulo chosapanga dzimbiri. Chitsulo chilichonse chokhala ndi 12% kapena chinanso chachitsulo chimawerengedwa chitsulo chosapanga dzimbiri. Chromium sikuti ndizosasinthika malinga ndi kukana kwa oxidation pamatenthedwe kwambiri. Chromium imawonjezera kukula, zokolola ndi kuuma firiji.

ASTM A335 ndi lingaliro lamphamvu kwa chitoliro chaching'ono cha alrieric chitoliro cha kutentha kwambiri. Covers server levels: P1, P2, P5, P5b, P5c, P9, P11, P12, P15, P21, P22, P23, P91, P92, P122, of which P5, P9, P11, P22, P91, P92 are used in practice the most extensive. Izi zimatulutsa khoma locheperako komanso locheperako molybdenum (lomwe limadziwikanso kuti Cr-moly) mapaipi achitsulo opangira kutentha. Chipika cholamulidwa ndi izi zidzakhala zoyenera kugwada, mbanja ndi zopangidwa chimodzimodzi, komanso nsabwe zowala. ASTM A335 P11, P21, P91 ndi P91 ndi P91 imagwiritsidwa ntchito m'mafakitale a mphamvu ndi matebulo, pomwe P9 ndi P9 amagwiritsidwa ntchito makamaka pokonzanso mafuta.
Aisi 4130 kalasi ndi chitsulo chotsika chokhala ndi zinthu monga chromium ndi Molybdenum yowonjezera ngati kulimbikitsa othandizira pakugawidwa kwake. Aisi 4130 chitoliro chimalandira chipilala chothandizirana ndi kutentha kapena kugwiritsa ntchito njira kuposa chitsulo cha kaboni wamba.
Zitsulo zachitsulo ndi zitsulo zomwe zimagwirizanitsa ndi zinthu zosiyanasiyana zokwanira pakati pa 1.0% ndi 50% ndi kulemera kwake kuti musinthe mphamvu zake. Zitsulo za alloy zimasweka m'magulu awiri: zitsulo zotsika komanso zitsulo zazitali. Kusiyana pakati pa awiriwo kumatsutsidwa. Smith ndi Ismahemu amatanthauzira kusiyana kwa 4.0%, pomwe degarmo, et al. Nthawi zambiri, mawu akuti "alloy chitsulo" amatanthauza zitsulo zotsika kwambiri.
Chitoliro chachitsulo chachitsulo chimapangidwa ndi chitsulo. Ili ndi mawonekedwe athunthu a Austenite ndipo ali ndi vuto labwino kutchula mitundu ingapo yowononga. Mapaipi awa ndi machubu ndi njira yotsika mtengo kwambiri yogwiritsa ntchito nthawi yayitali.
