Zoo thiab ntau ntawm stainless hlau welded yeeb nkab

Me txoj kab uas hla stainless hlau welded yeeb nkab yog tsim tsis tu ncua on-line. Qhov tuab ntawm phab ntsa tuab, ntau dua kev nqis peev ntawm chav tsev thiab cov khoom siv fusion, thiab kev lag luam tsawg dua thiab siv tau. Lub thinner phab ntsa thickness yog, qhov qis ntawm cov tswv yim-tso zis piv yuav yog; Qhov thib ob, cov txheej txheem ntawm cov khoom txiav txim siab nws qhov zoo thiab qhov tsis zoo. Feem ntau, cov welded steel yeeb nkab muaj qhov ua tau zoo, cov phab ntsa tuab tuab, qhov ci ntsa iab sab hauv thiab sab nraud ntawm cov yeeb nkab (qhov ci ntsa iab ntawm cov yeeb nkab steel tau txiav txim siab los ntawm qib qib ntawm cov hlau phaj), thiab tuaj yeem ua qhov loj me. Yog li ntawd, nws embodies nws kev lag luam thiab zoo nkauj nyob rau hauv daim ntawv thov ntawm high-precision, nruab nrab thiab tsis tshua muaj siab kua.

316L stainless hlau welded yeeb nkab yog ib qho yooj yim yeeb nkab, yog li nws kuj muaj ntau yam tsim nyog ntsuas ntawm hardness, nrog rau ntau yam. Cov hauv qab no yog hais txog hardness ntsuas ntawm 16L stainless hlau welded yeeb nkab. Raws li cov kev sim sib txawv thiab daim ntawv thov, qhov nyuaj tuaj yeem muab faib ua Brinell hardness, Rockwell hardness, Vickers hardness, shore hardness, microhardness thiab kub hardness. Brinell, Rockwell thiab Vickers hardness feem ntau yog siv rau cov kav dej.

1.Brinell hardness (HB) nias lub pob steel lossis cemented carbide pob nrog ib txoj kab uas hla mus rau hauv cov qauv saum npoo nrog lub zog ntsuas (f), tshem tawm qhov kev xeem quab yuam tom qab lub sijhawm tuav, ntsuas qhov indentation txoj kab uas hla (L) ntawm tus qauv nto, thiab Brinell hardness tus nqi yog cov quotient tau los ntawm kev faib cov kev xeem quab yuam los ntawm indentation spherical nto cheeb tsam. Qhia nyob rau hauv HBS (steel pob), chav tsev yog n / mm2 (MPA), thiab cov mis laij lej yog raws li nram no: F - xeem quab yuam nias rau saum npoo ntawm 316L stainless hlau welded yeeb nkab qauv, N, D - txoj kab uas hla ntawm steel pob rau kev xeem, MMD - uniform diameter ntawm indentation, mm. Kev txiav txim siab ntawm Brinell hardness yog qhov tseeb dua thiab txhim khu kev qha, tab sis feem ntau HBS tsuas yog tsim rau cov khoom siv hlau hauv qab 450N / mm2 (MPA), tsis yog rau cov hlau hnyav lossis nyias 316L stainless hlau welded yeeb nkab. Nyob rau hauv 316L stainless hlau welded yeeb nkab, Brinell hardness yog feem ntau siv. Indentation txoj kab uas hla D feem ntau yog siv los qhia qhov hardness ntawm cov khoom, uas yog intuitive thiab yooj yim.

Piv txwv li, 120hbs10 / 1000130 qhia tias Brinell hardness tus nqi ntsuas los ntawm kev siv lub 10 hli txoj kab uas hla steel pob nyob rau hauv qhov kev txiav txim ntawm 1000kgf (9.807kn) xeem quab yuam rau 30s yog 120N / mm2 (MPA).

2.Rockwell hardness (HK) Rockwell hardness test, zoo li Brinell hardness test, yog ib qho kev xeem indentation. Qhov txawv yog tias nws ntsuas qhov tob indentation, uas yog, nyob rau hauv qhov kev txiav txim ntawm thawj zaug Yong xeem quab yuam (FO) thiab tag nrho cov kev xeem quab yuam (f), nias lub indenter (steel mill cone lossis steel pob) rau hauv cov qauv saum npoo, tshem tawm. lub ntsiab kev xeem quab yuam tom qab txhais lub sij hawm tuav, thiab xam cov hardness tus nqi nrog ntsuas residual indentation tob increment (E). Nws tus nqi yog tus lej tsis paub, sawv cev los ntawm lub cim hr. Cov nplais siv suav nrog 9 nplai xws li a, B, C, D, e, F, G, h thiab K. Cov nplais feem ntau siv rau kev sim hardness ntawm 316L stainless hlau welded yeeb nkab feem ntau yog a, B thiab C, piv txwv li HRA, HRB thiab HRC. Tus nqi hardness yog xam los ntawm cov qauv hauv qab no: thaum ntsuas a thiab C siv rau kev xeem, HR = 100-e. thaum scale B siv rau kev xeem, HR = 130-e. nyob rau hauv cov mis, e - residual indentation qhov tob increment, uas yog qhia nyob rau hauv lub delimited unit ntawm 0.002mm, uas yog, thaum lub axial txav ntawm lub indenter yog ib chav tsev (0.002mm), nws yog sib npaug rau ib tug xov tooj ntawm Rockwell hardness. kev hloov.
