Hnav resistant steel phaj yog high-carbon alloy steel phaj.Qhov no txhais tau hais tias Wear resistant steel phaj yog ib qho nyuaj vim qhov sib ntxiv ntawm carbon, thiab formable thiab huab cua resistant vim ntxiv alloys.
Cov pa roj carbon ntxiv thaum lub sij hawm tsim cov hlau phaj ua kom muaj zog thiab tawv, tab sis txo lub zog.Yog li ntawd, Wear resistant steel phaj yog siv nyob rau hauv daim ntaub ntawv uas abrasions thiab hnav thiab tsim kua muag yog lub ntsiab ua rau tsis ua hauj lwm, xws li industrial manufacturing, mining, kev tsim kho thiab cov khoom tuav.Hnav resistant steel phaj tsis zoo tagnrho rau kev siv cov qauv siv xws li kev txhawb nqa beams hauv cov choj lossis cov tsev.
Qhov kev sib txawv ntawm kev puas ntsoog resistant steel phaj yog Brinell Hardness Number (BHN), uas qhia txog cov khoom qib hardness.Cov ntaub ntawv nrog BHNs siab dua muaj cov qib hardness ntau dua, thaum cov khoom siv nrog BHNs qis dua muaj qis dua ntawm hardness:
NM360 Hnav Resistant Steel Phaj: 320-400 BHN Feem ntau
NM400 Hnav Resistant Steel Phaj: 360-440 BHN Feem ntau
NM450 Hnav Resistant Steel Phaj: 460-544 BHN Feem ntau
Hnav-resistant steel rau kev tsim kho tshuab, nws yuav tsum muaj cov yam ntxwv zoo xws li hnav tsis kam, siab toughness, cuam tshuam tsis kam, vuam yooj yim, thiab yooj yim sib sau.Lub ntsiab qhia ntawm hnav tsis kam yog nto hardness.Qhov siab dua qhov hardness, qhov zoo dua qhov hnav tsis kam.
Impact resistance Txij li qhov cuam tshuam tau hais, NM hnav-tiv taus steel phaj muaj qhov cuam tshuam zoo, thiab muaj peev xwm tiv thaiv cov dents yog qhov zoo dua li cov qauv hlau zoo tib yam thaum raug hnyav.
Tau kawg, lub zog siab kuj yog qhov tseem ceeb ntawm kev ua tau zoo ntawm cov hlau hnav-resistant.Yog tsis muaj lub zog siab, tsis muaj kev cuam tshuam siab thiab hardness.Txawm li cas los xij, txawm tias lub zog tawm ntawm cov hlau tsis muaj zog tshaj 1000 MPa, qhov kub ntawm qhov cuam tshuam qis ntawm -40 ° C tseem tuaj yeem ncav cuag ntau dua 20J.Qhov no tso cai rau kev tsim kho tshuab tsheb kom nyab xeeb siv ntau qhov chaw hnyav.
