Uhlobo lokuqala luhlobo lwe-alloy ephantsi, emele ibakala le-UNS S32304 (23Cr-4Ni-0.1N). Insimbi ayinayo i-molybdenum, kwaye ixabiso le-PREN li-24-25. Ingasetyenziswa endaweni ye-AISI304 okanye i-316 ngokumalunga noxinzelelo lwe-corrosion resistance.
Uhlobo lwesibini luhlobo lwe-alloy ephakathi, ibakala elimele i-UNS S31803 (22Cr-5Ni-3Mo-0.15N), ixabiso le-PREN yi-32-33, kunye nokuchasana kwe-corrosion phakathi kwe-AISI 316L kunye ne-6% Mo + N austenitic stainless. intsimbi. phakathi.
Uhlobo lwesithathu luhlobo lwe-alloy ephezulu, ngokubanzi iqulethe i-25% ye-Cr, iqulethe i-molybdenum kunye ne-nitrogen, kwaye enye iqulethe i-copper kunye ne-tungsten. Umgangatho oqhelekileyo ngu-UNSS32550 (25Cr-6Ni-3Mo-2Cu-0.2N), kunye nexabiso le-PREN yi-38-39 Ukuxhatshazwa kwe-corrosion yolu hlobo lwensimbi luphezulu kune-22% ye-Cr duplex insimbi engenasici.
Uhlobo lwesine luyi-super duplex yensimbi engenasici, equkethe i-molybdenum ephezulu kunye ne-nitrogen. Umgangatho oqhelekileyo ngu-UNS S32750 (25Cr-7Ni-3.7Mo-0.3N), kwaye ezinye ziqulethe i-tungsten kunye nobhedu. Ixabiso le-PREN likhulu kune-40, elingasetyenziselwa iimeko ezinzima eziPhakathi, kunye nokumelana nokugqwesa okubanzi kunye neempawu zomatshini, ezifaniswa ne-super austenitic stainless steel.
