Common Procurement Pitfalls Thaum Hloov Sib Nqus Alloy 825:
- Daim ntawv pov thawj yuav tsum tau rau export xaj: Cov neeg siv khoom txawv teb chaws feem ntau xav tau MTC cimUNS N08825. Kev kos npe tsuas yog NS142 lossis 2.4858 ib leeg tuaj yeem raug tsis lees paub hauv cov phiaj xwm roj av / thoob ntiaj teb tshuaj lom neeg. EN 10204 3.1 / 3.2 daim ntawv pov thawj tshuaj xyuas tau pom zoo.
- Trace element tolerance sib txawv: Cov qauv sib txawv tso cai me me sib txawv rau S, C, Ti. Tsawg-sulfur tshav kub yog nyiam rau pickling & hnyav-welding fabrications. Cov pa roj carbon ntau ua rau muaj kev pheej hmoo ntawm inter-granular corrosion tom qab vuam.
- NACE qaub-gas limitation: Tsuas yog cov cua sov tau ntawv pov thawj UNS N08825 hauv kev daws teeb meem-nplua nuj txaus siab NACE MR0175. Tsis txhob cia siab rau cov npe lag luam sib npaug.
- NS142 domestic vs export: Hauv tsev NS142 tuaj yeem phim UNS N08825; ib txwm hais kom zeb tau lees paub ua raws li UNS N08825 rau kev xa khoom hla ciam teb.

FAQ:
Qhov txawv ntawm alloy 20 thiab INCOLOY 825 yog dab tsi?
Alloy 20 muaj zog nruab nrab, zoo ductility, thiab zoo weldability. Nws tuaj yeem tsim tau yooj yim rau hauv cov kav dej, cov ntawv txheeb, thiab cov fittings, ua rau nws muaj ntau yam rau cov khoom siv tshuaj. Incoloy 825 muab siab zog tensile thiab tawm los zog, superior toughness, thiab zoo heev ua hauj lwm nyob rau hauv siab kub.
Dab tsi yog qhov txawv ntawm INCOLOY 825 thiab AISI 316?
Hauv cov ntsiab lus, ob qho tib si Incoloy 825 thiab SS316 yog siab -kev ua tau zoo stainless hlau alloys nrog kev siv dav.Incoloy 825 muaj qhov tshwj xeeb corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv kev txo qhov chaw, thaum SS316 excels nyob rau hauv marine thiab tshuaj ib puag ncig..
Qhov txawv ntawm Inconel 925 thiab 825 yog dab tsi?
Alloy 825 (Incoloy 825, UNS N08825, 2.4858) thiab Alloy 925 (Incoloy 925, UNS N09925) yogyuav luag zoo tib yam nyob rau hauv muaj pes tsawg leeg, thiab yog li muab zoo heev corrosion kuj thiab lub cev muaj zog. Txawm li cas los xij, Alloy 925 muab qhov muaj zog ntau dua li nws tau txais txiaj ntsig los ntawm kev ua kom muaj zog los nag.
Qhov txawv ntawm INCOLOY 800 thiab 825 yog dab tsi?
Incoloy 800 muaj kev ntseeg siab siab - qhov kub thiab txias ntawm tus nqi qis, ua rau nws tsim nyog rau cov ntawv thov uas qhov kev pheej hmoo corrosion tseem nyob nruab nrab. Incoloy 825, nrog rau nws cov kev tiv thaiv zoo tshaj rau cov kua qaub thiab cov tshuaj chlorides, dhau los ua qhov kev xaiv zoo tshaj plaws rau cov chaw muaj tshuaj lom neeg hnyav, txawm tias nws txhais tau tias tus nqi siab dua.
INCOLOY txhais li cas?
Incoloy yog lub npe nrov rau ib pawg hlau sib xyaw, hu ua superalloys, feem ntau ua los ntawm npib tsib xee, hlau, thiab chromium. Nws yog tsim los kom muaj zog thiab tiv thaiv xeb los yog kev puas tsuaj hauv qhov chaw kub heev thiab cov tshuaj hnyav.
Puas yog Inconel 825 xeb?
Tus cwj pwm zoo ntawm INCOLOY 825 yog nws cov qib siab ntawm corrosion kuj. Nyob rau hauv ob qho tib si txo thiab oxidize ib puag ncig, lub alloyresists dav corrosion, pitting, crevice corrosion, intergranular corrosion, thiab kev nyuaj siab -corrosion cracking.
