654 SMO Stainless Hlau Phaj (UNS S32654, ASTM A240)

Khoom Taw Qhia

Thaum koj ntsib 654 SMO stainless hlau hauv koj cov txheej txheem kev yuav khoom, koj tab tom sawv ntawm "qhov kawg ntawm cov hlau tsis muaj steel hlau tsis zoo rau kev ua haujlwm pyramid." Qhov no tsis yog ib qho kev yuav khoom, tab sis yog ib qho kev daws teeb meem kev yuav khoom rau qhov chaw corrosive heev.

Nws yog super austenitic stainless hlau (SMO yog cov ntawv luv rau super austenitic stainless hlau). Nws cov txiaj ntsig tseem ceeb nyob hauv kev ua tiav qhov tsis tau pom dua ua ntej rau hauv cheeb tsam corrosion los ntawm cov chromium siab, molybdenum, thiab nitrogen cov ntsiab lus.

Kev Qhia Txog Kev Muag Khoom thiab Cov Qauv Kev Lag Luam

Koj 654 SMO stainless hlau phaj nug specifications yuav tsum nruj raws li kev pom zoo.

1. Txiav txim siab cov qauv thiab qib:

Tus qauv rau cov khoom siv hlau peb feem ntau muab yog ASTM A240 / A480. Cov qib sib koom ua ke feem ntau yog UNS S32654. Tus lej no yuav tsum tau siv; nws yog tus cim thoob ntiaj teb.

2. Qhia meej txog cov ntsiab lus tshwj xeeb thiab qhov kev xa khoom xa tuaj (Cretical Clause):

Raws li cov neeg siv khoom xav tau yav dhau los thiab cov khoom siv hauv kev lag luam, peb khaws cov khoom me me ntawm cov khoom no nrog cov lus qhia hauv qab no: thickness: 0.3mm - 150.0mm, dav: 1000mm - 3000mm. Qhov ntev tuaj yeem txiav raws li koj xav tau. Koj lub hauv paus ntsiab lus yuav tsum sib txuas lus nrog koj cov engineers thiab muab cov khoom tshwj xeeb thickness, dav, ntev, thiab nruj kam rau ua (xws li, thickness ± 5%).

Kev xa khoom xa tuaj: Yuav tsum tau hais meej meej hauv cov ntawv loj xws li "Kev daws teeb meem Annealed & Quenched". Qhov no tsuas yog txoj hauv kev kom tau txais cov austenite zoo ib yam thiab pom kev tiv thaiv corrosion.

3. Cov Ntsiab Cai Kev Ua Haujlwm (Tus Ntsuj Plig ntawm Daim Ntawv Pom Zoo Ua Haujlwm):

Cov ntaub ntawv tiv thaiv corrosion yuav tsum tau teev tseg: "Tus neeg muag khoom yuav tsum muab ASTM G48 Method Ib qho tseem ceeb pitting ntsuas kub ntsuas rau cov khoom siv no, thiab tus nqi CPT yuav tsum siab dua lossis sib npaug li 80 degree."

PREn tus nqi yuav tsum raug xam: "Raws li qhov muaj pes tsawg leeg hauv daim ntawv pov thawj zoo, cov khoom siv tus nqi PREn (%Cr + 3.3 × %Mo + 30 × %N) yuav tsum Ntau dua lossis sib npaug rau 54."

4. Cov Lus Qhia Tshwj Xeeb (Cov Nqi Ntxiv, tab sis tsim nyog):

Nto zoo: 2B (txias dov ci), No.1 (kub dov pickled), los yog polished nto. Qhov saum npoo siab yog xav tau rau cov phaj kub exchangers.

Tsis yog -kev kuaj kev puas tsuaj: Puas yog yuav tsum tau kuaj UT? Nws yog feem ntau yuav tsum tau rau siab - cov hlab ntsha siab.

Intergranular corrosion testing: Kev ntsuam xyuas raws li ASTM A262 Practice E (Streicher) thiab yuav tsum muaj daim ntawv qhia.

Ntim: Yuav tsum siv VCI los tiv thaiv- ntawv xeb lossis yas zaj duab xis rau kev ntim khoom cais kom tsis txhob muaj cov tshuaj chloride ion paug thiab puas.

Kev ua haujlwm nyuaj thiab cov ntsiab lus tseem ceeb

(Kev nkag siab txog cov laj thawj rau tus nqi exorbitant)

654 SMO stainless hlau yog ib qho nyuaj heev rau kev ua haujlwm kub vim nws cov ntsiab lus alloy siab, uas ua rau lub qhov rais ua haujlwm nqaim heev. Qhov kub dov kub yuav tsum tau tswj kom meej heev; txwv tsis pub, kev tawg yooj yim tuaj yeem tshwm sim. Qhov no ncaj qha ua rau cov nqi slab siab. Txawm hais tias yuav cov khoom siv raw, machining qhov yooj yim, lossis precision-machined qhov chaw, cov ntsiab lus hauv qab no yuav tsum raug sau tseg los ntawm cov neeg ua haujlwm paub txog kev ua haujlwm theem nrab:

Machining Challenges:

Lub zog siab heev thiab kev ua haujlwm hardening ua rau nws nyuaj heev rau tshuab. Cov cuab yeej hnav yog 5-10 npaug ntau dua thaum machining 316L stainless hlau.

Carbide los yog coated cov cuab yeej, tsawg txiav ceev, thiab siab -flow coolant yog yuav tsum tau.

Vuam Yuav tsum muaj -Tier Expertise:

Ultra- cov khoom siv hluav taws xob siab molybdenum (xws li Sanicro® 65 lossis Alloy 625) yuav tsum tau siv.

Kev tswj xyuas nruj ntawm cov khoom siv hluav taws xob thiab kev sib tshuam ntawm qhov kub thiab txias, nrog rau kev tiv thaiv rov qab kom zoo, yog qhov tseem ceeb los tiv thaiv kev txo qis hauv corrosion ntawm cov hlau vuam.

Ib -Stop Procurement Strongly Recommended:

Rau cov khoom siv tseem ceeb (xws li cov hlab ntsha siab), nws raug pom zoo kom hu ncaj qha rau ASME -cov chaw tsim khoom siab siab nrog kev paub txog kev siv tshuab 654 SMO. Lawv yuav tswj tag nrho cov txheej txheem los ntawm kev yuav cov phaj, txiav, sib sau, vuam, thiab kev kho cua sov, ua rau muaj kev tswj xyuas zoo dua. Kev yuav cov phaj koj tus kheej thiab tom qab ntawd outsourcing txoj haujlwm yog qhov txaus ntshai heev.
