SS 309S / SS 309H ucingo

I-SS 309S insimbi engenasici yintsimbi exutywe kakhulu ye-austenitic esetyenziselwa ukuxhathisa okugqwesileyo kwi-oxidation, ubushushu obuphezulu, amandla, kunye nokuxhathisa ukurhubuluza. Umxholo we-nickel ophantsi we-Stainless Steel 309, xa kuthelekiswa ne-Stainless Steel 310, ukwandisa ukuchasana kwayo nokuhlaselwa kwe-hydrogen sulfide (H2S) kumaqondo aphezulu. Iqinile kwaye i-ductile kwaye ingenziwa lula kwaye yenziwe ngoomatshini. I-SS 309S yinguqulelo yekhabhoni ephantsi, kwaye iyacetyiswa ukuba, isetyenziswe apho uvakalelo kunye nokonakala okulandelayo ngenxa yobushushu obuphezulu becondensates ngexesha lokuvalwa kunokuba ngumngeni. I-Stainless Steel 309S isetyenziselwa ukumelana nobushushu obuphezulu be-oxidation kunye nokumelana nohlaselo lwe-H2S. I-309S Stainless Steels inokuqulunqwa, isitampu kwaye izotywe ngokulula. I-in-process annealing idla ngokufuneka ukunyusa i-ductility kunye nokunciphisa ubulukhuni.
