13MnNiMoR yog lub zog muaj zog, siab tawv, qaug zog-resistant low-alloy steel, uas yog siv rau hauv kev tsim cov txuas hniav, cov hlab ntsha loj, cov ntug dej hiav txwv thiab lwm cov qauv tseem ceeb. Cov hlau no muaj kev tiv thaiv corrosion zoo heev ntawm qhov kub thiab txias zoo ntawm qhov kub thiab txias, ua rau nws siv dav hauv ntau hom kev siv.
Cov tshuaj muaj pes tsawg leeg ntawm 13MnNiMoR feem ntau muaj cov pa roj carbon, silicon, manganese, phosphorus, sulfur, chromium, npib tsib xee, tooj liab thiab lwm yam. Ntawm lawv, carbon yog lub ntsiab ntawm cov hlau, thiab cov ntsiab lus feem ntau yog 0.1% -0.2%. Silicon thiab manganese yog cov ntsiab lus alloying, uas tuaj yeem txhim kho lub zog thiab hardness ntawm hlau. Phosphorus thiab sulfur yog cov khoom tsis zoo thiab lawv cov ntsiab lus yuav tsum raug txo kom ntau li ntau tau. Chromium thiab npib tsib xee tuaj yeem txhim kho corrosion kuj ntawm hlau. Tooj liab tuaj yeem txhim kho atmospheric corrosion kuj ntawm hlau.
Cov khoom siv kho tshuab ntawm 13MnNiMoR feem ntau suav nrog lub zog tawm los, lub zog tensile, elongation thiab cuam tshuam toughness. Raws li cov kev xa khoom sib txawv thiab cov txheej txheem ua tiav, cov khoom siv zog ntawm 13MnNiMoR thaj tsam ntawm 240-410 MPa, lub zog tensile thaj tsam ntawm 490-620 MPa, qhov elongation Ntau dua lossis sib npaug li 18%, thiab qhov cuam tshuam toughness ntau dua tshaj los yog sib npaug 47 J / cm². Cov ntsuas kev ua tau zoo no qhia tau tias 13MnNiMoR muaj lub zog siab thiab hardness, zoo heev plasticity thiab toughness, thiab tuaj yeem tiv taus ntau yam kev ntxhov siab thiab deformation.
