I-ASTM A312 304L 316L 6mtr Iipayipi zeNtsimbi Engenamthungo Ezingwevu Ezimhlophe Umphezulu Ofakwe I-Pickled
Umbhobho wentsimbi engatyiwayosisiqwenga eside sentsimbi ye-alloy enganyangekiyo ngumhlwa. Icandelo layo eliphambili yintsimbi, equlethe ubuncinane i-10.5% ye-chromium (Cr). Izinto ezifana ne-nickel (Ni) kunye ne-molybdenum (Mo) zihlala zongezwa ukuphucula iipropati ezithile. Iimpawu zayo ezibalaseleyo kukumelana kwayo okugqwesileyo kokugqwala kunye ne-oxidation, ngenxa yefilimu exineneyo eyenziwe kumphezulu wayo, evumela ukusetyenziswa kwayo ngokubanzi kwiindawo ezifumileyo, ezibolayo ngamakhemikhali, okanye ezishushu kakhulu. Umbhobho wentsimbi engatyiwayo ukwanika amandla agqwesileyo, ukuqina, ucoceko (kulula ukuwucoca nokubulala iintsholongwane), kunye nokusebenza kakuhle komatshini kunye nokuwelda. Izinto eziqhelekileyo ziquka iintsimbi ezingatyiwayo ze-austenitic ezifana ne-304 (injongo eqhelekileyo) kunye ne-316 (enganyangekiyo ngakumbi kumhlwa, equlethe i-molybdenum). Ukusetyenziswa kwayo kwahlukahlukene kakhulu, kuquka ukuhombisa izakhiwo (ii-handrails, ii-guardrails), ukuthuthwa kolwelo (amanzi, igesi, i-chemical media), ukucutshungulwa kokutya neziselo, izixhobo zonyango, ukuveliswa kweemoto, amashishini amandla (ipetroli, amandla enyukliya), iimpahla zasekhaya, kunye nezixhobo ezichanekileyo. Sisixhobo esibalulekileyo esibalulekileyo kushishino nakubomi banamhlanje. Unyango lomphezulu olufana nokupholisha kunye nokugquma isanti lungasetyenziswa ukuhlangabezana neemfuno zobuhle kunye nokusebenza. Ngokubanzi, imibhobho yentsimbi engagqwaliyo zezona zinto zikhethwayo zemibhobho kwiindawo ezininzi ngenxa yokuqina kwayo, ucoceko, ubuhle bayo, kunye nokuguquguquka kwayo.

Umbhobho wentsimbi engenamthungo we-ASTM osemgangathweni ophezulu omelana nobushushu 431 631 Ityhubhu yentsimbi engagqwaliyo
Iipayipi zentsimbi engagqwali zenziwe ngentsimbi engagqwali enomxholo we-chromium ≥10.5% (ezifana neeklasi eziqhelekileyo ezingama-304 kunye nama-316L). Zinamandla aphezulu (amandla okutsalwa ≥515MPa), ukumelana nokugqwala okugqwesileyo (ifilimu yokuthambisa umphezulu ayimelani nokugqwala kwe-asidi/ityuwa) kunye nokhuseleko lococeko (ukugqitywa komphezulu womgangatho wokutya i-Ra≤0.8μm). Zenziwe ngeenkqubo zombhobho wokuqengqeleka obandayo ongenamthungo okanye welding oqhelekileyo kwaye zisetyenziswa kakhulu kwiipayipi zeekhemikhali (316L ezimelana ne-asidi), izakhiwo zezakhiwo (ii-304 curtain wall keels), izixhobo zonyango (iipayipi ezicocekileyo ezicocekileyo) kunye nezixhobo zamandla (iipayipi zokudlulisa ubushushu obuphantsi kakhulu be-LNG). Zezona zixhobo ziphambili kwicandelo lokuvelisa eliphezulu.
