Dab tsi yog cov paib zog zog ntawm stpg370 yeeb nkab

1. Mechanical Performance index
Lub zog tensile: ntau dua los yog sib npaug rau 370 MPa (Yam tsawg kawg nkaus tus nqi yuav tsum tau los ntawm JIS G3454 Txuj Ci);
Paib tau taw tes / tawm lub zog: ntau dua los yog sib npaug rau 215 MPa (lub zog tseem ceeb ntawm cov khoom los pib yas deformation);
Elongation:
Longitudinal (No. 11, 12 Zawm): Loj dua lossis sib npaug rau 30%;
Transverse (No. 5 hnoos qeev): Loj dua lossis sib npaug 25%;
POBE TEST YUAV TSUM:
Welded qhov chaw yuav tsum tau dhau 2/3 yeeb nkab Thia Thia Thomtion Dreadation ntsuas;
Cov khoom siv ntawm niam txiv yuav tsum hla dhau 1/3 yeeb nkab ntawm txoj kab uas hla kev deformation xeem.
2. Daim Ntawv Thov Kev Ua Haujlwm Zoo
Kev ua haujlwm txias: Haum rau cov kab kos txias, dov thiab lwm cov txheej txheem, elongation kom tau raws li cov kev xav tau ntawm precision leeg);
Corrosion Kuj: raws li ib tug carbon hlau, nws yuav tsum tau txhim kho los ntawm kev kho mob saum npoo (EG plating) kom txhim kho kev thauj khoom ntawm cov khoom tsis muaj zog corrosive.
3. Kev thov cov xwm txheej thiab kev txheeb xyuas
Kev siv tau: Hauv txoj kab nrog Jis G3454 txheem txheej txheem phab ntsa tuab tsawg dua lossis sib npaug rau 8 hli steel yeeb nkab tsis muaj. 15, No. 5 yuav tsum tau ua;
Kev Siv: Roj / Roj / Roj Kev Tsim Kho, Kev Tsim Kho Cov Tub Ntxhais, Kev Tsim Kho Qes Rau Cov Tshuab Hydraulic Thiab Lwm Yam Tsawg Thiab Nruab Nrab Lo Loadarios.
Ntsiab lus: Stpg370 yuav siv ntau dua lossis sib npaug ntawm 370 MPA tensile lub zog thiab ntau dua los yog sib npaug ntawm 21%) thiab txias ua zog
