Imveliso:
Into ebizwa ngokuba yi-duplex stainless steel kwisisombululo sayo esiqinileyo sesigaba se-ferrite kunye ne-austenite idibana nesiqingatha ngasinye, ngokubanzi umxholo ongaphantsi komxholo kufuneka ufikelele kwi-30%. Kwimeko ye-C ephantsi, umxholo we-Cr we-18% ukuya kwi-28%, umxholo we-Ni we-3% ukuya kwi-10%. Enye intsimbi iqulethe i-Mo, i-Cu, i-Nb, i-Ti, i-N kunye nezinye izinto zokudibanisa.
Iingenelo.
Intsimbi ineempawu zentsimbi ye-austenitic kunye ne-ferritic,
1. kuthelekiswa ne-ferrite, iplastiki, ubunzima obuphezulu, akukho brittleness yobushushu begumbi, ukuxhathisa kwi-corrosion ye-intergranular kunye nokusebenza kwe-welding kuyaphuculwa kakhulu, ngelixa i-mainta ining iron I-Qualified stainless steel 475 ℃ brittleness kunye ne-thermal conductivity ephezulu, kunye ne-superplasticity njalo njalo.
2. Ukuthelekisa kunye ne-austenitic stainless steel, amandla aphezulu kunye nokuchasana ne-intergranular corrosion kunye nokuchasana ne-chloride stress corrosion kuye kwaphucula kakhulu.
3. I-Duplex yensimbi engenasici inokumelana okuncomekayo kwi-pitting resistance corrosion, kodwa kunye necandelo le-nickel stainless steel.
