SA387 GR22 Cov Hlau Hlau Hlau yog ib hom chromium {2} Kuv tau lees paub rau lawv cov khoom siv neeg kho tshuab (corrosion. Lawv feem ntau tsim rau high - siab} siab, siab}} kub (HPHT) hauv kev lag luam tseem ceeb. Hauv qab no yog cov ncauj lus kom ntxaws saib xyuas:

Tshuaj Muaj Tshuaj

Cov ntsiab lus tseem ceeb tshaj plaws hauv Sa387 Gr22 daim hlau pab rau lawv cov khoom lag luam zoo siab:

 

Chromium (cr): 2.00-2.50% - Cov ntaub ntawv ntom xim oxide kom tiv thaiv siab- kub oxidation thiab txhim kho corrosion tsis kam.

Molybdenum (mo): 0.90-1.10% - txhim kho cov ferrite lawb tawm (tiv taus rau deformation nyob rau hauv ntev {}} kub ntxhov siab ntawm cov tshuab ntsuas kub.

Carbon (c): Tsawg dua los yog sib npaug rau 0.15% - tshuav hluav taws xob muaj zog thiab weldability; Cov ntsiab lus muaj cov roj carbon tsawg tsawg tsawg kev pheej hmoo ntawm cov tawv nqaij tawv thiab tawg thaum lub sij hawm vuam.

Lwm cov khoom: manganese (mn), silicon (Si), phosphorus (p), cov kev txwv nruj (nrog nruj qoj ib ce kom paub tseeb thiab ua tau zoo).

Cov Khoom Siv Neeg Kho Tshuab

Tom qab txheem kev kho cua sov (li qub + tempering), sa387 gr22 daim phiaj pom cov ntse hauv qab no cov khoom siv:

 

 

 

 

 

 

 

 

Lub zog tensile: 415-585 mpa

Paib lub zog: Ntau dua los yog sib npaug rau 205 MPa

Elongation: Ntau dua los yog sib npaug rau 22% (hauv 200 hli gauge ntev)

Kev Cuam Tshuam: Zoo nruj ntawm chav thiab nce qhov kub thiab txias, ua kom muaj kev tsis kam mus rau brittle lov tsis tshua muaj kev thauj khoom.

Cov Khoom Siv Tseem Ceeb

Siab - kub kev ua tau zoo

Kev Pabcuam Kub: Tuaj yeem ua haujlwm ntev - sij hawm hauv kub txog li 550 degree. Ntawm cov cua nabatures, lawv tswj lub zog ruaj khov, kom muaj zog, ua rau lawv muaj zog, ua rau lawv haum rau kev ua kom sov tas li.

Cov quav: Molybdenum lub sijhawm muaj cov qoob loo muaj kev phom sij thiab kev cuam tshuam cov kev pheej hmoo ntawm cov tub rog muaj kev phom sij
