Raws li peb cov kev sib tham yav dhau los ntawm cov txheej txheem kev daws teeb meem thiab kev ua haujlwm ntawm cov kub khiav stainless hlau bolts, cov txheej txheem tseem ceeb rau kev txiav txim siab seb cov kev kho mob puas tau raws li cov qauv hauv qab no:
Hardness Standard: Lub hardness ntawm 304/316 stainless hlau bolts tom qab kev kho mob yuav tsum tsawg tshaj li los yog sib npaug rau HB187, tsis muaj lub zos nyuaj me ntsis los tiv thaiv nkig tawg thaum lub sij hawm installation.
Metallographic Standard: Cov qauv metallographic yuav tsum yog ib qho tib yam -theem austenite uas tsis pom tseeb carbide nag lossis daus ntawm cov ciam teb nplej thiab tsis muaj qhov txawv txav loj loj.
Corrosion Resistance Standard: Tsis muaj qhov pom tseeb ntawm kev xeb yuav tsum tshwm sim li ntawm 3 feeb tom qab siv cov tshuaj ntsuam xyuas tshwj xeeb, thiab yuav tsum tsis muaj qhov cuam tshuam rau intergranular corrosion.
Residual Stress Standard: Kev ntsuam xyuas kev ntxhov siab yuav tsum paub meej tias qhov tsis muaj qhov tseem ceeb ntawm kev ntxhov siab sab hauv, thiab tsis muaj deformation lossis loosening yuav tsum tshwm sim nyob rau hauv siab - kub.
Txheej Txheem Traceability Standard: Lub Hoobkas daim ntawv tshaj tawm yuav tsum qhia meej tias qhov ntsuas kub, lub sijhawm, thiab txoj kev ua kom txias ua raws li cov txheej txheem kev kho mob rau cov khoom siv sib xws.
Cov qauv no tau ua raws li lub teb chaws tus qauv GB/T 1220 rau stainless hlau thaum tshav kub kub kev kho mob, kom ntseeg tau ntev -lub sij hawm kev cia siab ntawm kub khiav bolts.
