Taw qhia
AISI 321 / JIS SUS321 Austenite tshav kub resistant stainless hlau bar.
Hom 321 stainless hlau yog Ni - Cr - Ti austenitic stainless hlau, nws qhov kev ua tau zoo yog zoo li 304, tab sis vim yog koom nrog cov hlau titanium, ua kom nws muaj cov nplej zoo dua ua hauj corrosion thiab siab kub lub zog. Vim tias ntxiv cov titanium, ua rau nws ua tau zoo tswj kev tsim cov chromium carbide.
321 stainless hlau muaj qhov kub zoo heev Kev nyuaj siab Lub cev tsis meej (Cov kev nyuaj siab ua kom cov nyom) thiab cov siab kub siab ua haujlwm (Kev Nyuaj Ua Ntej) Kev nyuaj siab thiab cov khoom siv tshuab tau zoo dua li ntawm 304 stainless hlau.
Cov Qauv: ASTM, JIS, GB, EN (DIN, BS, NF) Los yog Raws li cov neeg yuav tsum tau muaj.

Seamless steel yeeb nkab txheej txheem:
Cov txheej txheem kev tsim ntawm kev ua haujlwm dav hlau seamless tau muab faib ua ob hom: cov khaub thuas sib twv thiab kub-dov. Cov txheej txheem ntau dua ntawm cov khaub thuas sib tw txias-kub seamless cov hlab tub raj feem ntau muaj cov nyom ntau dua li kub-dov. Lub raj raj dawb yuav tsum xub muab tso rau peb-yob tas mus li dov, thiab tom qab ntawd extruded. Hauv kev ntsuas sizing, yog hais tias qhov saum npoo tsis teb rau cov kab nrib pleb, cov yeeb nkab puag ncig yog txiav los ntawm lub tshuab txiav thiab txiav rau hauv qhov khoob ntawm kwv yees ib metre ntev. Tom qab ntawd nkag mus rau hauv cov txheej txheem annealing. Kev thov kom sib deev yuav tsum tau ntxuav cov kua qaub nrog cov kua nyeem kua qaub. Thaum de, xyuam xim seb puas muaj qhov loj ntawm cov hlwv rau saum npoo. Yog tias muaj qhov loj ntawm cov hlwv, qhov tsis zoo ntawm cov yeeb nkab steel tsis tuaj yeem ua tau raws li tus qauv teb. Cov tsos ntawm txias-dov seamless steel yeeb nkab yog luv dua li uas ntawm kub-kuav los tiag seamless steel yeeb. Lub tuab ntawm txias txias-dov seamless steel yeeb nkab yog feem ntau me dua li cov kub-kuav los tiag cov yeeb nkab steel, tab sis saum npoo zoo li ci dua li cov tuab-walled seamless steel yeeb nkab. Nws yog qhov ntxhib, thiab nws tsis muaj burr ntau. Qhov kub-dov seamless steel yeeb nkab feem ntau xa mus rau hauv lub xeev kub-txuas tom qab kev kho cua sov. Kub-kuav los tiag seamless steel kav yog yuav nruj kev xaiv phau ntawv los ntawm cov neeg ua haujlwm tom qab kev soj ntsuam zoo. Tom qab soj ntsuam zoo, lub nplaim roj, tom qab los ntawm ntau qhov kev sim txias txias. Tom qab txoj kev kho kub-dov, ib txoj kev sim perforation yog ua. Yog hais tias lub cheeb ntawm perforation loj dhau, kev qhia ncaj qha yuav tsum tau kho. Tom qab qhov ncaj, nws yuav pauv mus rau qhov ntsuas qhov khuam los ntawm lub tshuab ntsuas lub nrig rau qhov kev tshawb nrhiav qhov khuam. Thaum kawg, cov ntawv lo tau sau tseg thiab qhov kev qhia tshwj xeeb tau teem thiab tso rau hauv tsev rau khoom.
