Peb Qhov Zoo
● Peb tau koom nrog steel pob ntau lawm ntau tshaj 26 xyoo;
● Peb muab ntau qhov ntau thiab tsawg ntawm 3.175mm txog 38.1mm.Qhov ntau thiab tsawg thiab ntsuas tsis tau tsim tau raws li kev thov tshwj xeeb (xws li 5.1mm, 5.15mm, 5.2mm, 5.3mm 5.4mm rau lub rooj taug kev; 14.0mm rau cam ncej thiab CV sib koom, thiab lwm yam);
● Peb muaj cov khoom lag luam dav dav.Feem ntau ntawm cov qauv loj (3.175mm ~ 38.1mm) thiab ntsuas ntsuas (-8 ~ + 8) muaj, uas tuaj yeem xa tuaj sai;
● Txhua pob khoom raug tshuaj xyuas los ntawm cov tshuab sophisticated: roundness tester, roughness tester, metallographic tsom tsom iav, hardness tester (HRC thiab HV) kom lav qhov zoo.
FAQ
Q: Kuv yuav xaiv lub hom stainless hlau tsim nyog (304 (L) / 316 (L) / 420 (C) / 440 (C))?Dab tsi yog qhov txawv ntawm 300 thiab 400 series stainless hlau pob?
A: Txhawm rau xaiv cov khoom lag luam hlau zoo rau cov khoom tsis muaj steel hlau, peb yuav tsum paub zoo txog cov khoom ntawm txhua hom thiab daim ntawv thov ntawm cov khoom.Feem ntau siv stainless hlau pob tuaj yeem muab faib ua ob pawg: 300 series thiab 400 series.
300 series "austenitic" stainless hlau npas muaj ntau cov chromium thiab npib tsib xee thiab yog cov theoretically tsis-sib nqus (qhov tseeb yog cov hlau nplaum tsawg heev. Tsis yog-sib nqus yuav tsum tau kho cua sov ntxiv.).Feem ntau lawv raug tsim tsis muaj txheej txheem kho cua sov.Lawv muaj kev tiv thaiv corrosion zoo dua li 400 series (qhov tseeb, qhov siab tshaj plaws corrosion kuj ntawm cov stainless pawg. Txawm hais tias 300 series pob yog tag nrho cov resistant, txawm li cas los xij 316 thiab 304 pob qhia sib txawv rau qee yam khoom. Yog xav paub ntxiv, thov mus saib nplooj ntawv ntawm txawv stainless hlau pob).Lawv tsis nkig tsawg, yog li tuaj yeem siv rau kev siv sealing.400 series stainless hlau pob muaj ntau cov pa roj carbon ntau, uas ua rau nws sib nqus thiab ntau hardness.Lawv tuaj yeem kho tau yooj yim thaum tshav kub kub xws li chrome steel npas lossis carbon steel pob kom nce hardness.400 series stainless hlau pob yog feem ntau siv rau cov ntawv thov uas xav tau dej-ua haujlwm, lub zog, hardness thiab hnav tsis kam.
Q: Koj qhov kev lees paub zoo li cas?
A: Tag nrho cov khoom tsim tawm yog 100% txheeb xyuas los ntawm kev txheeb xyuas thiab txheeb xyuas los ntawm lub tshuab photoelectric defect detector.Ua ntej ntim cov qauv pob los ntawm ntau yog xa mus rau qhov kawg kev tshuaj ntsuam xyuas kom paub qhov roughness, roundness, hardness, variation, crush load thiab vibration raws li tus qauv.Yog tias tag nrho cov kev xav tau ua tiav, daim ntawv tshuaj ntsuam xyuas yuav raug ua rau tus neeg siv khoom.Peb lub chaw soj ntsuam sophisticated yog nruab nrog siab precision tshuab thiab khoom siv: Rockwell hardness tester, Vickers hardness tester, crushing load tshuab, roughness meter, roundness meter, txoj kab uas hla sib piv, metallographic microscope, vibration ntsuas ntsuas, thiab lwm yam.
