Puas yog siab -frequency resistance welding (HFW) thiab hluav taws xob arc vuam (ERW) tib yam?
Tsis yog,HFWthiab ERW tsis zoo ib yam, txawm hais tiasHFWyog hom ERW. Qhov sib txawv tseem ceeb yog tias HFW siv siab - zaus tam sim no los ua kom sov cov npoo hlau los ntawm "cov nyhuv ntawm daim tawv nqaij thiab qhov sib thooj," uas ua rau cov vuam nrawm dua thiab meej dua; thaum ERW yog ib pawg dav dav uas suav nrog qis- zaus vuam thiab lwm yam kev siv vuam tsis kam.
Puas yog qib 43 steel S275?
Tsis yog, qib 43 steel tsis ncaj nraim rauS275, txawm hais tias lawv qhov tsawg kawg nkaus tawm lub zog zoo sib xws (kwv yees li 275 MPa).
Dab tsi yog qhov txawv ntawm ASTM A36 thiab S275?
ASTM A36 yog ua los ntawm cov pa roj carbon steel thiab qis- alloy steel, nrog rau qhov tsawg kawg nkaus lub zog ntawm 36,000 psi. S275JR, ntawm qhov tod tes, yog ua los ntawm carbon steel, manganese steel, thiab silicon steel, nrog rau qhov tsawg kawg nkaus lub zog ntawm 27,000 psi. Qhov no txhais tau hais tias ASTM A36 muaj lub zog ntau dua, thaum S275JR muaj qhov zoo dua ductility thiab machinability.
Dab tsi yog qhov zoo ntawm S275 steel?
Lub ntsiab zoo ntawm S275 steel yog nws zoo heev weldability thiab formability, ua rau nws yooj yim rau txheej txheem thiab haum rau dav thiab nruab nrab - siv zog ntawm tus nqi - zoo nqi.
Dab tsi yog cov ntawv thov ntawm S275 steel?
S275 hlauyog dav siv nyob rau hauv kev tsim kho daim ntawv thov, xws li structural Cheebtsam rau lub tsev thiab txuas hniav. Nws kuj tseem siv rau hauv kev lag luam tsheb, cov cuab yeej siv hnyav, kev lag luam roj thiab roj, thiab cov tshuab tsim khoom siv rau kev tsim khoom qis -load Cheebtsam xws li bushings thiab axles.
