1. EN 10297 X6CrNiMoTi17-12-2 yog dab tsi?
Teb:
TS EN 10297 X6CrNiMoTi17-12-2stabilized austenitic stainless hlau seamless rajRaws li European tus qauv EN 10297. Nws yog titanium -stabilized variant ntawm 316Ti (AISI 316Ti), tsim los tiv thaiv rhiab heev thaum vuam.
Lub ntsiab lus tseem ceeb:17% Cr, 12% Ni, 2% Mo, thiab titanium (Ti) Ntau dua lossis sib npaug li 5 × C cov ntsiab lus los khi cov pa roj carbon.
Qib sib npaug:UNS S31635, DIN 1.4571.
Feature tseem ceeb:Superior intergranular corrosion kuj tom qab vuam los yog siab - kub raug.
2. Cov khoom siv tshuab yog dab tsi?
Teb (kev kho mob annealed):
Tensile zog:520-720 MPa
Yield zog (0.2% offset):Ntau dua lossis sib npaug li 205 MPa
Elongation:Ntau dua lossis sib npaug li 40%
Hardness:Tsawg dua lossis sib npaug li 215 HB
Nco tseg:Ti stabilization txo cov nag lossis daus carbide, tswj cov ductility hauv cov qauv welded.
3. Nws txawv li cas ntawm cov qib uas tsis yog -stabilized zoo li X5CrNiMo17-12-2 (316L)?
Teb:
Stabilization:Ti hauv X6CrNiMoTi17-12-2 tiv thaiv chromium carbide tsim (sensitization) ntawm 450-850 degree, tsis zoo li 316L.
Daim ntawv thov:Nyiam rau welded Cheebtsam hauvsiab - qhov kub thiab txias(piv txwv li, tso pa tawm, cua kub exchangers).
Kev pauv - tawm:Me ntsis txo machinability vim Ti carbides.
4. Cov txheej txheem tsim khoom tseem ceeb yog dab tsi?
Teb:
Vuam:Siv cov khoom siv hlau sib txuam (xws li ER316Ti). Tsis muaj kev tshaj tawm -weld kho cua sov xav tau rau feem ntau.
Machining:Ti nce cov cuab yeej hnav; siv cov cuab yeej ntse carbide thiab qis qis.
Kev tiv thaiv corrosion: Avoid prolonged exposure to temperatures >850℃los tiv thaiv σ-theem embrittlement.
5. Qhov qhab nia no feem ntau siv rau qhov twg?
Teb:
Automotive:Exhaust manifolds, turbocharger qhov chaw (tiv thaiv thermal cycling).
Kev ua tshuaj lom neeg:Piping rau acidic/chloride-nplua nuj media.
Zog:Boiler raj, superheater Cheebtsam.
Kev kho mob:Implantable li (biocompatible, ruaj khov tom qab sterilization).
