1. EN 10297 X2NiCrAlTi32-20 yog dab tsi?
Teb:
TS EN 10297 X2NiCrAlTi32-20nickel-chromium-aluminium-titanium alloyed austenitic stainless hlau seamless rajstandardized raws li EN 10297, tsim rau siab -kub thiab corrosive ib puag ncig.
Lub ntsiab lus tseem ceeb:32% Ni, 20% Cr, nrog ntxiv ntawm Al (aluminium) thiab Ti (titanium) rau oxidation kuj thiab stabilization.
Qib sib npaug:Zoo ib yam li UNS N08330 (Incoloy 330) lossis DIN 1.4886.
Feature tseem ceeb:Tshwj xeebthermal stability(txog 1100 degree) thiab tiv taus carburization / sulfidation.
2. Cov khoom siv tshuab yog dab tsi?
Teb (kev kho mob annealed):
Tensile zog:600-850 MPa
Yield zog (0.2% offset):Ntau dua lossis sib npaug li 250 MPa
Elongation:Ntau dua lossis sib npaug li 30%
Hardness:Tsawg dua lossis sib npaug li 220 HB
Nco tseg:Aluminium thiab titanium txhim khu kev nkag siab ntawm qhov kub siab.
3. Nws txawv li cas ntawm cov txheej txheem cua sov-cov hlau tiv taus zoo li 310S (X8CrNi25-21)?
Teb:
Al/Ti Stabilization:X2NiCrAlTi32-20 resistscarburizationthiabhlau plua plavzoo dua 310S vim Al / Ti oxide txheej tsim.
Nickel Cov ntsiab lus:Siab dua Ni (32% vs. 25%) txhim kho kev tiv thaiv kom tsis txhob muaj huab cua (xws li hydrogen- ib puag ncig nplua nuj).
Daim ntawv thov:Nyiam raupetrochemical cracking rauvthiabthermal ua khoom siv.
4. Cov txheej txheem tsim khoom tseem ceeb yog dab tsi?
Teb:
Vuam:Siv TIG nrogERNiCr-3 (Inconel 82)muab tub lim. Ua ntej- cua sov rau 150-200℃kom tsis txhob tawg.
Machining:Kev ua haujlwm siab- tus nqi hardening yuav tsum muaj cov cuab yeej carbide thiab tus nqi pub tsawg.
Kev kho cua sov:Kev daws anneal ntawm 1050-1150℃tom qab txias txias kom ua kom zoo dua microstructure.
5. Qib no feem ntau siv qhov twg?
Teb:
Petrochemical:Ethylene cracking tubes, hloov kho qhov cub.
Kev tsim hluav taws xob:Superheater raj hauv thee / biomass boilers.
Aerospace:Exhaust Cheebtsam thiab afterburners.
Kev kho cua sov:Annealing fixtures thiab radiant tubes.
