Biphase Stainless Steel
Ingxubevange yobushushu obuphezulu
◆F51 (31803) yeyona duplex isetyenziswa kakhulu intsimbi stainless, ikakhulu esetyenziswa kwi oyile omuncu kunye negesi imveliso kakuhle, ekucokiseni ioli, imichiza, isichumisi, petrochemical kunye nezinye iinkalo, ukwenzela ukuveliswa kokutshintshiselana kobushushu, ukupholisa okupholileyo, njl. ezithambekele ekufakeni i-corrosion kunye noxinzelelo lwe-corrosion yezixhobo zoxinzelelo. Endaweni ye-304L, i-316L i-austenitic stainless steel.
◆ F53 (S32750) i-super duplex steel stainless ene-nitrogen eyongeziweyo, esetyenziswa kakhulu kwiikhemikhali, i-petrochemical kunye nezixhobo zaselwandle ezifuna amandla akhethekileyo kunye nokuxhathisa ukubola.
I-◆F55 (S32760) yintsimbi ye-super duplex enamandla amakhulu, ukuxhathisa okuphezulu kwi-kloride yendawo ye-corrosion kunye ne-corrosion yoxinzelelo, kunye ne-weldable.
I-◆329 (S32900) inokumelana ne-oxidation efanelekileyo, ukuxhathisa ukubola, amandla aphezulu, kwaye ifanelekile kwiindawo ezifana nokuxhathisa ukubola kwamanzi olwandle.
◆ Insimbi ye-A4 (0Cr17Mn13Mo2N) yintsimbi ye-double-phase, kwaye ukuxhathisa kwayo kwe-corrosion kungcono kuneyona nto isetyenziswa ngokuqhelekileyo i-austenitic steel kunye ne-Mo content of 2% -3%. Inokuthi isetyenziswe kwizichumisi ezincinci zeekhemikhali, izixhobo ze-urea ezijikelezayo, njl.
I-◆S31050 inokumelana okuphezulu kwi-chloride yoxinzelelo lwe-corrosion cracking, ukuchasana okugqwesileyo kwi-pitting corrosion kunye ne-crevice corrosion.
◆ I-U3 ineempawu zokunqanda ukukhuhla kunye ne-anti-corrosion, kwaye isoloko isetyenziselwa ukwenza i-valve cores, izihlalo zevalve kunye nezinye iinxalenye zangaphakathi zevalvu.
◆HD isetyenziswa ngokubanzi kwishishini le-elektroniki, imboni ye-photoelectric, i-petrochemical industry, i-automobile industry kunye nezinye iimpompo ze-oyile zombane ezilawula isantya.
◆C4 ilungele imixube emikhulu emi nkqo, abaxubi, abaxube, abaxube abathe tye kunye namanye amashishini oomatshini.
◆DS-2 inokumelana nomhlwa kubushushu obuphezulu obugxininise kwi-asidi yesulfuric, kwaye ifanelekile kushishino loomatshini kushishino lobushushu obuphezulu obugxininiswe kwi-asidi ye-sulfuric.
