Vim lub siab yield point, siab hardness thiab tseem ceeb txias ua hauj lwm hardening nyhuv ntawm stainless hlau,stainless hlau dabtsi yog khoovmuaj cov yam ntxwv hauv qab no:
1) Vim tias cov thermal conductivity tsis zoo dua li cov hlau tsis tshua muaj carbon tsawg thiab qhov elongation tsawg, qhov xav tau deformation quab yuam loj;
2) 321 stainless hlau daim ntawv muaj ib tug muaj zog rebound tendency piv nrog carbon steel thaum khoov;
3) Vim qhov qis elongation ntawm stainless hlau daim hlau piv rau carbon steel, lub dabtsi yog khoov lub kaum sab xis R ntawm lub workpiece thaum lub sij hawm khoov yuav tsum muaj ntau tshaj li ntawm cov hlau, txwv tsis pub tej zaum yuav tawg:
4) VimLub siab hardness ntawm SUS304 stainless hlau phajthiab qhov tseem ceeb ntawm kev ua haujlwm txias txias, thaum xaiv cov cuab yeej khoov xovxwm, koj yuav tsum xaiv cov cuab yeej steel nrog kev kho cua sov ntawm qhov siab tshaj 60HRC. Nws qhov roughness saum npoo yog qhov kev txiav txim ntawm qhov loj dua li cov pa roj carbon steel xovxwm dabtsi yog khoov cov cuab yeej.
Raws li cov yam ntxwv saum toj no, feem ntau hais lus:
1. Nyob rau hauv chav tsev loj, lub phaj thicker, qhov ntau dua qhov yuav tsum tau khoov quab yuam, thiab raws li lub phaj thickness nce, cov npoo rau dabtsi yog khoov quab yuam yuav tsum ntau dua thaum xaiv cov khoom dabtsi yog khoov;
2. Nyob rau hauv chav tsev loj, lub zog tensile ntau dua, qhov me me ntawm qhov elongation, qhov ntau dua qhov yuav tsum tau muaj zog dabtsi yog khoov, thiab lub kaum sab xis yuav tsum loj dua;
3. Thaum lub phaj thickness sib haum mus rau lub vojvoog dabtsi yog khoov nyob rau hauv tus tsim daim duab, raws li kev paub, qhov nthuav loj ntawm ib tug dabtsi yog khoov workpiece yog cov sum ntawm txoj cai-angled sab rho tawm ob lub phaj thicknesses, uas muaj peev xwm ua tau raws li qhov tsim nyog cov cai. . Tus nqi nthuav dav tuaj yeem suav tau raws li cov qauv empirical. Simplifying cov txheej txheem suav zoo heev txhim kho kev tsim khoom;
4. Qhov ntau dua lub zog ntawm cov khoom siv, qhov ntau dua elastic rov qab. Kom tau txais 90-degree kaum raustainless hlau bent ib feem, lub kaum sab xis ntawm cov xovxwm riam yuav tsum tau tsim kom me me. Piv nrog carbon steel nrog tib lub phaj tuab, stainless hlau muaj lub kaum sab xis loj dua. Kev saib xyuas tshwj xeeb yuav tsum tau them rau qhov no, txwv tsis pub cov kab nrib pleb yuav tshwm sim thiab cuam tshuam rau lub zog ntawm lub workpiece.
