Q580R steel phaj yog ib hom tempered high-strength steel phaj, Q580R yog qib tshiab, kev siv lub teb chaws tus qauv tshiab GB/T713.6-2023, tuaj yeem dov. Kev xa khoom: quenched thiab tempered tempered xeev, tempering kub tsis tsawg tshaj 600 degree, tib qib thiab Q580DR (-50 degree cuam tshuam).
Q580R Hom kev nthuav qhia
Q - yield zog "yield" thawj tsab ntawv ntawm lo lus hanyu pinyin;
580 - qhov kev txwv qis dua ntawm lub zog tawm los ntawm cov kev cai ntawm tus nqi qis dua, chav tsev yog MPa (MPa);
R - lub nkoj siab "Rong" ntawm thawj tsab ntawv ntawm hanyu pinyin.
Q580R steel phaj tshuaj muaj pes tsawg leeg yuav tsum ua raws li lub teb chaws tus qauv GB/T713 tshiab. Ntawm lawv, cov ntsiab lus tseem ceeb suav nrog carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel thiab lwm yam. Cov ntsiab lus thiab kev faib ua feem ntawm cov ntsiab lus ncaj qha cuam tshuam rau lub zog, toughness, corrosion kuj ntawm steel phaj.
Q580R steel phaj muaj cov cuab yeej zoo heev xws li lub zog siab, siab toughness, qaug zog thiab cuam tshuam tsis kam. Nws lub zog tensile tuaj yeem ncav cuag 690MPa lossis ntau dua, lub zog tawm los yog li 580MPa, thiab elongation yog ntau dua 16%. Tom qab qee qhov txheej txheem kho cua sov, nws lub zog thiab tawv tuaj yeem txhim kho ntxiv.
