Biphase Stainless Steel
Alloy e phahameng ea mocheso
◆F51 (31803) ke tšepe e sa hloekang ea duplex e sebelisoang ka ho fetisisa, e sebelisoang haholo-holo ho hlahisa oli e bolila le khase, ho hloekisa oli, lik'hemik'hale, manyolo, petrochemical le masimo a mang, bakeng sa ho etsa lihlahisoa tsa mocheso, condensing coolers, joalo-joalo. tse atisang ho baka kutu le khatello ea maikutlo ea lisebelisoa tsa khatello. Sebakeng sa 304L, 316L austenitic tšepe e sa hloekang.
◆F53 (S32750) ke super duplex tšepe e sa hloekang e nang le naetrojene e kenyelletsoeng, e sebelisoang haholo-holo lik'hemik'hale, petrochemical le lisebelisoa tsa leoatleng tse hlokang matla a khethehileng le ho hanyetsa kutu.
◆F55 (S32760) ke super duplex stainless steel e nang le matla a phahameng, e hanyetsanang le chloride localized corrosion le stress corrosion, le weldable.
◆329 (S32900) e na le khanyetso e ntle ea oxidation, corrosion resistance, matla a phahameng, 'me e loketse libaka tse kang metsi a leoatle a hanyetsang ho senya.
◆ A4 steel (0Cr17Mn13Mo2N) ke tšepe e nang le likarolo tse peli, 'me ho hanyetsa ha eona ha kutu ho molemo ho feta ho sebelisoa ka tloaelo tšepe ea austenitic e nang le Mo content ea 2% -3%. E ka sebelisoa ho menontsha ea lik'hemik'hale tse nyane, lisebelisoa tse felletseng tsa urea, joalo-joalo.
◆S31050 e na le khanyetso e phahameng ea chloride stress corrosion cracking, khanyetso e babatsehang ea pitting corrosion le crevice corrosion.
◆ U3 e na le thepa e thibelang ho senya le ho thibela ho bola, 'me hangata e sebelisetsoa ho etsa li-valve cores, litulo tsa li-valve le likarolo tse ling tsa ka hare tsa li-valve.
◆HD e sebelisoa haholo indastering ea elektronike, indasteri ea lifoto, indasteri ea petrochemical, indasteri ea likoloi le lipompo tse ling tse laolang lebelo la oli ea motlakase.
◆C4 e loketse li-mixer tse kholo tse holimo, li-mixer, li-mixer, li-mixer tse holimo le liindasteri tse ling tsa mechine.
◆ DS-2 e na le ho hanyetsa kutu ka mocheso o phahameng o nang le sulfuric acid, 'me e loketse indasteri ea mechine ea indasteri ea mocheso e phahameng ea sulfuric acid.
