Stainless Hlau Hlau, Kuj Known li Stainless Hlau Hlau

Stainless hlau hlau, kuj hu ua stainless hlau hlau, ua los ntawm stainless hlau rau ntawm ntau hom ntau hom kev sib txawv thiab cov qauv ntawm cov khoom siv silk, lub hauv paus chiv keeb ntawm Teb Chaws Asmeskas, lub Netherlands, Nyij Pooj, feem ntau puag ncig los yog ca . Cov kev sib txhuam hauv kev sib raug zoo yog qhov zoo, raug nyiaj tsis zoo hlau tsis xaim hlau yog 304 thiab 316 xim hlau xaim.

Stainless steel wire drawing Kos tus qauv hlau los yog xaim hlau los ntawm lub qhov tuag ntawm qhov kos duab tuag ntawm qhov kev txiav txim ntawm kev kos duab los ua ib txoj yas hlau ntawm ib qho me me hla hlau hlau los yog cov hlau tsis yog hlau. Txhua hom hlau thiab hlau los ntawm ntau hom ntoo sib hloov thiab qhov loj ntawm cov hlau yuav siv los rub tawm ntau lawm. Tsav tawm lub xaim, qhov loj ntawm qhov tseeb, tus dav saum npoo, thiab kev siv cov khoom kos thiab tuag yog yooj yim, yooj yim los tsim.

Nyob hauv txoj kev sib tw, kev nyuaj siab tawm ntawm σ1 ntawm txoj kev tawm dag zog ntawm thaj tsam ntawm cov kab hauv qhov kos yog siv rau tus tuag. Yuav kom cov yas deformation ntawm cov hlau hauv lub qhov tuag, qhov tensile nyuab siab σ1 yuav tsum muaj ntau dua qhov deformation tsis kam ntawm cov hlau hauv cov cheeb tsam deformation ntawm qhov tuag qhov. Txhawm rau tiv thaiv cov xaim los ntawm kev ua deformed tom qab tuag qhov deformed, Pulling txheej txheem, lub tensile nyuab siab σ1 yuav tsum muaj tsawg tshaj li qhov kev txwv qis ntawm cov kos vias tom qab lub qhov tuag qhov, yog li qhov kev tsim nyog rau kev paub txog kev kos duab feem ntau Sau raws li: σT <σ1><> Qhov ratio ntawm K mus rau lawv qhov sib piv yog hu ua txoj kev nyab xeeb ntawm kev kos duab.

Mob

Thiab yields txwv σs yog ze ntawm nws lub zog txwv σb. Nyob rau hauv cov khoom, σb yog siv instead of σs. Yog li, qhov xwm txheej ntawm txoj kev kos duab tau hais tau tias yog σT <σ1><> Qhov kev nyab xeeb ntawm kev nyab xeeb ntawm K ntawm kev kos duab tau hais tau los ntawm qhov sib piv ntawm σb rau σ1.

Kev nyab xeeb kev nyab xeeb

Txoj kev ntsuas txoj kev nyab xeeb muaj nqis K yog feem ntau ntawm 1.40 ~ 2.0, K <1.40 uas="" cuam="" tshuam="" rau="" stress="" σ1="" loj="" heev,="" lub="" qhov="" tuag="" tom="" qab="" lub="" xaim="" txuas="" ntxiv="" deformation="" tshwm="" sim="" los="" yog="" rub="" tawm="" qhov="" tshwm="" sim="" ntawm="" kev="" kos="" duab="" tsis="" ruaj=""> K> 2.0 qhia tau tias qhov tensile siab σ1 me me, tus nqi ntawm daim duab deformation me heev, rub txoj kev ntxiv. Nyob rau hauv daim duab ntawm txoj kab uas tsis pub tshaj ntawm 0.05mm ultra-fine hlau, hnav pwm nyuaj, txhawm rau txhim kho kom ruaj ntseg ntawm txoj kev sib tw los txo cov naj npawb ntawm rub thiab hnav tuaj yeem ua kom zoo ntawm kev kos duab, Tus nqi yuav siab tshaj 2.0.

Txheej txheem cwj pwm cov editor

Txoj kev nyuab siab ntawm txoj kab xaim hlau yog qhov peb lub hauv paus tsev kawm ntawv kev nyuaj siab ntawm ob txoj kev nyuab siab, uas yog yooj yim mus cuag lub xeev deformation lub cev tshaj li qhov peb sab kev nruj siab. Lub xeev deformation ntawm txoj kev kos yog ib txoj kev lag luam uas yog kev ua kom ob tog sib deformation uas yog ob txoj kev sib nraus deformation yog qhov ua rau lub cev tsis sib haum xeeb, uas yog qhov tsis zoo rau cov khoom siv hlau, thiab nws yooj yim tsim thiab nthuav tawm cov teeb meem ntawm qhov tsis ncaj. Kev rhuav tshem ntawm cov txheej txheem kab xaim yog txwv tsis pub muaj kev nyab xeeb. Tus deformation ntawm cov hlau yog me me, thiab tus naj npawb ntawm cov kis tau ntau dua. Vim li no, feem ntau cov vev-nruas qis siv ceev yog siv ntau zuj zus.

Feem ntau hauv raws li lub austenite, ferrite, ob-txoj kev tsis muaj stainless hlau thiab Markov stainless hlau, tsuas yog muab faib ua 2 series, 3 series, 4 series, 5 series thiab 6 series ntawm stainless hlau.

316 thiab 317 steel hlau (317 steel hlau tsis pom kev hauv qab) yog molybdenum stainless hlau. 317 stainless hlau hauv cov molybdenum cov ntsiab lus me ntsis siab dua nyob rau hauv 316 steel hlau vim lub molybdenum hlau, tag nrho kev ua tau zoo ntawm cov hlau yog zoo tshaj 310 thiab 304 stainless hlau, kub kub, thaum sulfuric acid concentration ntawm tsawg dua 15% thiab Siab dua 85% Cov kav hlau muaj ntau yam siv. 316 tsis muaj hlau tsis zoo kuj ua rau chloride yaig, yog li nws yog siv rau hauv cov kev sib xyuam xim. 316L stainless hlau ntau tshaj carbon cov ntsiab lus ntawm 0.03, yuav siv tom qab welding tsis tau annealed thiab xav tau kev tiv thaiv siab tshaj plaws nyob rau hauv kev siv.

Kev tawg rau ntawm qhov ntsuas kub ntawm qhov ntau ntawm 1850 txog 2050 degrees, tom qab ntawd chwv sai sai, thiab tom qab txias txias. 316 stainless hlau tsis tau superheated rau harden.

Welding

316 stainless hlau muaj zoo vuam kev kawm. Txhua txoj kev ntsuas welding yuav siv tau rau qhov txuas. Vuam siv tau raws li kev siv 316 Cb, 316L los yog 309 Cb stainless hlau muab tubular lossis vuam electrodes. Rau qhov zoo tshaj plaws corrosion kuj, 316 stainless hlau welded seem yuav tsum tau tom qab weld annealing. Yog tias siv 316L stainless hlau, tsis muaj qhov yuav tsum tau tiv thaiv kev tiv thaiv.
