ASTM A182 qhia txog tensile thiab hardness yuav tsum tau rau ntau yam alloy thiab stainless hlau qib siv nyob rau hauv high-kub kev pab cuam daim ntawv thov, xws li yeeb nkab flanges, fittings, thiab li qub. Tensile yuav tsum tau hais txog qhov tsawg kawg nkaus lub zog ntawm cov khoom yuav tsum muaj, suav nrog lub zog tawm los, lub zog tensile kawg, thiab elongation. Hardness yuav tsum tau qhia qhov siab tshaj plaws hardness tso cai rau cov khoom siv machinability thiab tsis kam mus deformation.
Nws yog ib qho tseem ceeb kom nco ntsoov ntau qhov kev txiav txim siab txog cov cai no:
1. Ua raws li:Cov neeg tsim khoom yuav tsum xyuas kom meej tias cov ntaub ntawv uas lawv tsim tau raws li qhov yuav tsum tau muaj tensile thiab hardness tau teev tseg hauv ASTM A182.
2. Kev xaiv cov khoom siv:Cov kws tsim qauv tsim thiab cov neeg yuav khoom yuav tsum ua tib zoo xav txog qhov xav tau lub zog tensile thiab hardness qib raws li daim ntawv thov thiab kev ua haujlwm.
3. Quality Assurance:Cov txheej txheem tswj kev ua tau zoo, suav nrog cov khoom siv kuaj thiab tshuaj xyuas, yog qhov tseem ceeb rau kev txheeb xyuas kev ua raws li ASTM A182 cov cai thiab ua kom cov khoom zoo thiab kev ua haujlwm zoo.
4. Kev kho cua sov:Cov txheej txheem kho cua sov kom zoo yog qhov tseem ceeb kom ua tiav cov khoom xav tau thiab cov qib hardness tau teev tseg hauv ASTM A182 rau qib steel sib txawv.
5. Vuam:Cov txheej txheem vuam yuav tsum raug xaiv thiab ua raws li cov qauv tsim nyog thiab cov lus qhia kom tsis txhob cuam tshuam cov khoom siv kho tshuab thiab hardness ntawm cov khoom.
6. Cov ntaub ntawv:Cov ntaub ntawv tsim nyog, suav nrog cov ntaub ntawv xeem cov ntaub ntawv (MTRs), yuav tsum tau khaws cia kom ua tau raws li ASTM A182 cov kev cai thiab kev taug qab ntawm cov ntaub ntawv siv hauv kev tsim kho lossis kev siv hauv kev lag luam.
