1. EN 10297 X5CrNiMo17-12-2 yog dab tsi?
Teb:
TS EN 10297 X5CrNiMo17-12-2seamless stainless hlau rajstandardized raws li European cai EN 10297. Nws belongs rau lubaustenitic stainless hlautsev neeg (zoo ib yam li AISI 316L) nrog kev ua haujlwm siab corrosion, zoo heev weldability, thiab txhua yam muaj zog.
Kev sib xyaw:17% Cr, 12% Ni, 2% Mo, qis carbon (0.07% max).
Kev siv:Hydraulic systems, aerospace, chemical processing, thiab marine applications.
2. Dab tsi yog cov khoom siv ntawm cov hlau no?
Teb:Tej yam khoom (annealed condition):
Tensile zog:500-700 MPa
Yield zog (0.2% offset):Ntau tshaj lossis sib npaug li 200 MPa
Elongation:Ntau dua lossis sib npaug li 40%
Hardness:Tsawg dua lossis sib npaug li 215 HB
Nco tseg:Cov khoom sib txawv nrog kev kho cua sov thiab kev ua haujlwm txias.
3. X5CrNiMo17-12-2 piv rau AISI 316L li cas?
Teb:
Zoo sib xws:Ob leeg yog austenitic, muaj kev tiv thaiv corrosion zoo heev (tshwj xeeb tshaj yog tiv thaiv chlorides), thiab muaj Mo rau pitting kuj.
Qhov txawv:TS EN 10297 Kev ntsuas nruj dua rau cov raj seamless, thaum AISI 316L yog cov qauv siv dav dua. X5CrNiMo17-12-2 tej zaum yuav tau hloov me ntsis Cr/Ni piv rau European cov cai.
4. Cov txheej txheem vuam thiab fabrication yog dab tsi?
Teb:
Vuam:Siv txoj kev TIG/MIG nrog cov khoom siv hlau sib xws (xws li ER316L). Pre/post-weld heat treatment tsis tshua xav tau.
Machining:Tsawg carbon cov ntsiab lus txo cov carbide nag lossis daus; siv cov cuab yeej ntse thiab ua kom txias txaus.
Corrosion Risk:Tsis txhob cuam tshuam ntev mus rau 450-850℃kom tsis txhob hnov qab.
5. Qhov twg yog EN 10297 X5CrNiMo17-12-2 nquag siv?
Teb:
Roj & Roj:Subsea Cheebtsam.
Kev kho mob:Cov cuab yeej phais (biocompatible).
Kev lag luam zaub mov:Hygienic tubing (resists acidic ib puag ncig).
Automotive:High -txoj kev tso pa tawm.
