Kev siv cov hlau stainless

Hardness

Stainless hlau raj feem ntau siv brinell, Rockwell, Vickers peb hardness ntsuas los ntsuas nws hardness.

Brinell hardness

Nyob rau hauv cov txheej txheem stainless hlau raj, brinell hardness yog siv dav tshaj plaws, feem ntau rau indentation txoj kab uas hla los qhia cov hardness ntawm cov khoom, ob qho tib si intuitive thiab yooj yim.Txawm li cas los xij, nws tsis haum rau cov kav hlau uas tawv lossis nyias.

Rockwell hardness

Rockwell hardness test ntawm stainless hlau raj yog tib yam li brinell hardness test, uas yog indentation test method.Qhov txawv yog tias nws ntsuas qhov tob ntawm qhov indentation.Rockwell hardness test yog ib txoj kev siv dav siv tam sim no, ntawm cov HRC tsuas yog thib ob rau Brinell hardness HB hauv cov yeeb nkab steel.Rockwell hardness tuaj yeem siv los txiav txim siab los ntawm cov khoom muag muag heev rau cov khoom siv hlau nyuaj, nws ua rau Brinell txoj kev tsis yog, yog yooj yim dua li txoj kev brinell, tuaj yeem ncaj qha los ntawm lub tshuab hardness dial nyeem hardness tus nqi.Txawm li cas los xij, vim qhov me me indentation, tus nqi hardness tsis yog raws li txoj kev buchwald.

Vickers hardness

Stainless hlau raj Vickers hardness test kuj yog ib qho kev xeem indentation, tuaj yeem siv los txiav txim siab hardness ntawm cov ntaub ntawv hlau nyias thiab txheej txheej.Nws muaj cov txiaj ntsig tseem ceeb ntawm Brinell thiab Rockwell txoj hauv kev thiab kov yeej lawv qhov tsis zoo, tab sis nws tsis yooj yim li Rockwell txoj kev thiab tsis tshua siv hauv cov qauv yeeb nkab steel.

Kev sim hardness

Sab hauv txoj kab uas hla ntawm stainless hlau yeeb nkab yog ntau tshaj 6.0 hli, thiab phab ntsa thickness yog tsawg tshaj li 13 hli.Lub annealed stainless hlau yeeb nkab tuaj yeem kuaj los ntawm W-B75 Hom Wechsler hardness tester.Nws yog qhov nrawm heev thiab yooj yim, thiab haum rau kev tshuaj xyuas sai thiab tsis muaj kev puas tsuaj ntawm cov yeeb nkab steel hlau.Stainless hlau yeeb nkab puab txoj kab uas hla yog ntau tshaj 30 hli, phab ntsa thickness yog ntau tshaj 1.2 hli stainless hlau yeeb nkab, rockwell hardness tester, kuaj HRB, HRC hardness.Stainless hlau raj nrog lub taub sab hauv siab dua 30 hli thiab phab ntsa thickness tsawg dua 1.2 hli tau sim rau HRT lossis HRN hardness los ntawm nto Rockwell hardness tester.Rau cov kav hlau tsis muaj steel nrog lub taub sab hauv tsawg dua 0mm thiab ntau dua 4.8mm, rockwell hardness tester yog siv los kuaj HR15T hardness.Thaum txoj kab uas hla ntawm stainless hlau yeeb nkab yog ntau dua 26 hli, koj tuaj yeem siv Rockwell los yog nto Rockwell hardness tester los ntsuas qhov hardness ntawm sab hauv phab ntsa ntawm cov yeeb nkab.

Txoj kev loj hlob ntawm stainless hlau

Tag nrho ob qhov kawg ntawm qhov qhib thiab hollow seem, thiab nws qhov ntev thiab ntu ncig ntawm cov hlau loj, tuaj yeem hu ua steel yeeb nkab.Thaum qhov ntev thiab ntu ib ncig ntawm qhov sib piv me me, tuaj yeem hu ua ntu yeeb nkab lossis cov yeeb nkab fittings, lawv txhua tus yog nyob rau hauv qeb ntawm cov khoom siv yeeb nkab.

Rau ntau tshaj 60 xyoo, architects tau siv cov hlau tsis muaj steel los tsim cov khoom siv nyiaj txiag ruaj khov.Ntau lub tsev uas twb muaj lawm qhia txog qhov tseeb ntawm qhov kev xaiv no.Qee qhov zoo nkauj heev, xws li Chrysler Tsev hauv New York City.Tab sis nyob rau hauv ntau lwm yam kev siv, stainless hlau plays ib tug tsawg txaus ntshai tab sis tseem ceeb luag hauj lwm nyob rau hauv kev zoo nkauj thiab kev ua tau zoo ntawm lub tsev.Stainless hlau, piv txwv li, yog cov khoom ntawm kev xaiv rau cov neeg tsim qauv tsim kev taug kev hauv cov chaw tsheb loj vim tias nws tiv taus ntau dua rau kev puas tsuaj thiab creasing dua lwm cov hlau ntawm tib lub thickness.

Stainless hlau tau siv los ua cov khoom siv rau kev tsim kho vaj tse tshiab thiab kev kho dua tshiab ntawm cov chaw keeb kwm rau ntau tshaj 70 xyoo.Cov qauv tsim thaum ntxov tau ua raws li cov hauv paus ntsiab lus ntawm kev suav.Niaj hnub no, cov qauv tsim tshwj xeeb, xws li ANSI / ASCE-8-90 "Design Code for Cold-formed Stainless Steel Structural Parts" tus qauv thiab "Structural Stainless Steel Design Manual" luam tawm ua ke los ntawm NiDI thiab Euro Inox, tau ua kom yooj yim rau kev tsim qauv ntawm ntev-lub neej, zoo-tswj cov khoom siv rau cov tsev.

Stainless hlau xa tawm yog ib feem tseem ceeb ntawm Tuam Tshoj txoj kev lag luam xa tawm, nws ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa Tuam Tshoj txoj kev lag luam kev loj hlob, tab sis los ntawm cov xwm txheej tam sim no ntawm Tuam Tshoj stainless hlau kev lag luam txawv teb chaws, Tuam Tshoj stainless hlau xa tawm ntsib ntau dua kev tiv thaiv.

Txij li thaum xyoo tas los, txawv teb chaws feem ntau tuaj rau stainless hlau casting khoom nyob rau hauv Tuam Tshoj "ob rov qab" cov lus, nws muaj ib tug zoo ntxim rau cov stainless hlau casting kev lag luam nyob rau hauv Tuam Tshoj, thiab exports yog ib feem zoo ntawm stainless hlau kev lag luam kev loj hlob nyob rau hauv peb lub teb chaws. , nyob rau hauv txoj kev loj hlob ntawm kev lag luam muaj kev lag luam loj loj, nyob rau hauv lub ntsej muag ntawm kev lag luam poob qis, kev loj hlob qeeb, Stainless hlau kev lag luam kev loj hlob nyob rau hauv peb lub teb chaws yuav tsum tsis tu ncua txhim kho cov khoom zoo, zoo dua kev loj hlob ntawm kev lag luam tawm txawv teb chaws thiab tiv thaiv kev lag luam tiv thaiv, cov khoom lag luam thiab kev tiv thaiv ib puag ncig, kev siv hluav taws xob, tib neeg ib puag ncig, txhim khu kev sib tw ntawm cov khoom siv stainless hlau, tsuas yog nyob rau hauv txoj kev no tuaj yeem ua haujlwm tsis zoo hauv kev lag luam txawv teb chaws.
