Kev Piav Qhia Luv:

UNS S31254 Cov Hlau Stainless Hlau. UNS S31254 yog cov hlau stainless hlau super austenitic uas muaj cov molybdenum thiab nitrogen ntau, muab kev tiv thaiv zoo rau kev xeb pitting thiab crevice nrog rau lub zog siab piv rau cov hlau stainless hlau austenitic ib txwm muaj xws li 316L. UNS S31254 yog qib austenitic uas cov chromium, molybdenum thiab nitrogen ntxiv rau muab kev tiv thaiv zoo rau kev xeb pitting hauv dej hiav txwv. Cov hlau no muaj tus lej Pitting Resistance Equivalent Number nruab nrab (‚PREN' = Cr+3.3Mo+16N) ntawm 43.8. Cov kev sim qhia tau tias muaj kev tiv thaiv zoo rau kev tawm tsam crevice-corrosion hauv dej hiav txwv thiab rau kev ntxhov siab corrosion cracking hauv cov kub concentrated sodium chloride. Piv nrog CrNiMo 17 12 2.5 steels, nws qhia tau tias muaj kev tiv thaiv corrosion zoo dua hauv ntau cov kua qaub ntawm cov concentration zoo sib xws thiab nws lub zog tso zis yog kwv yees li 50%. Zoo weldability siv Ni-Cr-Mo consumables. Kev ua kom quench annealing thiab lub sijhawm luv luv hauv 600-1000 ° C ntau yam zam kev txhim kho ntawm cov theem sigma uas tsis zoo, uas yuav ua rau embrittle thiab ua rau tsis kam corrosion.
