Vim li cas thiaj xaiv 317L Tshaj 316L?
Thaum tus qauv 316L yog lub hauv paus kev xaiv rau kev ua dej hiav txwv thiab tshuaj lom neeg, cov txheej txheem hnyav hnyav yuav tsum muaj kev txhim kho ntawm Alloy 317L:
Elevated Molybdenum Cov ntsiab lus:Muaj3.0% mus rau 4.0% Mo(piv rau 2.0%–3.0% hauv 316L), 317L muab ntau dua Pitting Resistance Equivalent Number (PREN), ua rau nws muaj zog tiv thaiv halide ib puag ncig uas muaj chlorides lossis bromides.
Superior Creep Strength:Cov alloy ua kom pom cov khoom zoo heev nyob rau hauv kev ntxhov siab thermal, muab kev nkag siab dua - mus rau - kev txwv tsis pub muaj zog thiab tensile kev ua tau zoo dua li cov qauv 18-8 stainless hlau.
Fabricability zoo heev:317L tuaj yeem tsim tau yooj yim thiab welded siv cov txheej txheem khw tsim khoom. Siv cov khoom sib xyaw ua ke cov hlau, xws liSWB 317L, xyuas kom lub weld cheeb tsam tswj zoo tib yam corrosion kuj rau lub hauv paus hlau.
