Qib 630 stainless hlau ({17-4 pH): cov khoom, lub zog, thiab cov ntawv thov

 

Cov Qauv Tseem Ceeb & Cov Lus Qhia

• ASTM A564 (Txheem rau kub / txias-ua tiav-tiav lawm)
• Ams 5604, Ams 5643 (Aerospace Cov Khoom Siv Tshwj Xeeb)
• NACE MR0175 ua raws li kev pab qaub (roj & roj)

 

Cov Khoom Ntawm Qib 630 Stainless Hlau

 

1. corrosion tsis kam

Piv rauQeb 304 Stainless HlauNyob rau hauv feem ntau ib puag ncig .

Zoo heev tiv taus rau kev ntxhov siab corrosion cracking (SCC), tshwj xeeb tshaj yog thaum muaj hnub nyoog ntau dua .

Tsis tsim nyog rau cov chloride ib puag ncigYog tsis muaj kev tiv thaiv kab tiv thaiv .

Ua raws liNACE MR0175rau cov roj av ntws mus & roj av (tiv taus sulfide-inducles SCC) .

2.} pa hluav taws

Kev Ua Haujlwm: -29℃rau 343 degree({-20℃f rau 650℃f) .

Zam kev ntev ntev ntawm 370-500℃(700-930℃f)kom tiv thaiv embittlement .

Oxidation tsis kamyog qis dua rau 304/316 tab sis txaus rau ntau cov ntawv thov kub siab-{3}}

{{03. lub zog & cov khoom siv mechanical

Qib 630 yogib qho ntawm cov hlau muaj zog tshaj plaws, surpassing Austenitic (e {.}}}}}}}}} {}} {}}

4. weldability

Tuaj yeem welded tsis muaj preheatingsiv cov qauv txheej txheem zoo sib xws rau 300-} series stainless hlau .

Pom zoo muab tub lim hlau: 17-7 pH(rau txuam weld proferties) .

Tom qab-Weld Kev Kho Cua Sovrestores tag nrho lub zog thiab corrosion tsis kam .

 

Cov ntawv thov ntawm qib 630 (17-4 pH) stainless hlau

Vim nws lub zog siab, corrosion tsis kam, thiab kub ua kom kub, qib 630 tau siv dav hauv:

Roj & Roj Kev Lag Luam

• Downhole cov cuab yeej, li qub, WHEHHEAD Cheebtsam
• Twj tso qoob loo, cov khoom siv tshuab hluav taws xob, thiab cov khoom siv Drilling (NACE MR0175 ua raws li)

Aerospace & Tiv Thaiv

• Cov dav hlau tsaws iav, Turbine Cov Hniav, Cheebtsam
• Missile thiab Rocket Qauv

Industrial & Tshuaj Lom

• Kev loj-siab li qub, zog, thiab shafts
• Nuclear Khibe Casks, Reactor Cheebtsam
• Ntawv Zeb Machinery, Khoom Siv Ua Yeeb Yam

Tooling & Raug

• Moulding tuag, siab-zog ceev ceev
• Kev phais, cov khoom siv roj teeb

 

Vim li cas thiaj xaiv qib 630 (17-4 pH)?

Qib 630 Stainless Hlau muaj kev sib xyaw ua ke, xeb kev ua haujlwm tseem ceeb rau kev ua kom pom cov khoom tseem ceeb, thaum nws cov dej num tseem ceeb muab kev hloov kho hauv kev ua kom huv si.

 

Rau cov phiaj xwm yuav tsum muaj lub zog muaj zog yam tsis muaj kev txi ua hauj lwm, qib 630 ({}}}}} p p) yog qhov tsis muaj zog ntawm cov hlwv los yog ob qho tib si stainless hlau {2}
