50Mn steel phaj yog nruab nrab -carbon manganese steel paub txog nws lub zog siab, hnav tsis kam, thiab nruab nrab hardenability, ua rau nws tsim nyog rau cov ntawv thov uas yuav tsum tau muaj cov qauv zoo thiab ua haujlwm ntev. Hauv qab no yog cov ncauj lus kom ntxaws txog nws cov khoom, kev tsim khoom, kev siv, thiab cov ntsiab lus tseem ceeb:

Material Classification thiab Standards

50Mn belongs rau lubcarbon{0}}manganese structural steelqeb, txhais los ntawm Suav tus qauvGB / T 699-2015 《Carbon Structural Steels nthuav qhia. Nws yog sib npaug rau ASTM A29 / A29M Qib 1050 (hloov nrog cov manganese siab dua) thiab DIN 17200 Qib C50E hauv qee daim ntawv thov, txawm hais tias muaj pes tsawg leeg yuav txawv raws li tus qauv.

Tshuaj muaj pes tsawg leeg

Cov tshuaj muaj pes tsawg leeg ntawm 50Mn (ib GB / T 699-2015) yog nruj me ntsis tswj kom sib npaug zog thiab kev ua tau zoo:

 

Cov pa roj carbon (C): 0.47-0.55% (thawj lub zog ntxiv, txhim kho hardness thiab hnav tsis kam).

Manganese (Mn): 0.70–1.00% (txhim kho hardenability, tensile zog, thiab txo brittleness).

Silicon (Si): Tsawg dua lossis sib npaug li 0.37% (pab deoxidation thiab txhim kho lub zog).

Phosphorus (P): Tsawg dua los yog sib npaug rau 0.035% (tseem txwv kom tsis txhob brittleness).

Sulfur (S): Tsawg dua lossis sib npaug li 0.035% (tsawg kawg kom tiv thaiv kub tawg thaum ua haujlwm).

 

 

 

 

Mechanical Properties

50Mn's mechanical kev ua tau zoo yog nyob ntawm kev kho cua sov, nrog qhov sib txawv tseem ceeb ntawm annealed thiab quenched -tempered (Q&T) hais tias:

 

Khoom	Lub Xeev Annealed	Quenched & Tempered (Q&T)	Test Standard
Tensile zog (σb)	Ntau dua lossis sib npaug li 645 MPa	785-980 MPa	GB/T 228.1-2010
Yield zog (σs/σ0.2)	Ntau dua lossis sib npaug li 390 MPa	Ntau dua lossis sib npaug li 635 MPa	GB/T 228.1-2010
Elongation (d 5)	Ntau dua lossis sib npaug li 17%	10–15%	GB/T 228.1-2010
Impact Toughness (kv)	Ntau tshaj lossis sib npaug rau 20 J / cm² (ntawm 20 degree)	Ntau dua lossis sib npaug li 30 J / cm² (ntawm 20 degree)	GB/T 229-2020
Hardness (HBW)	197–255	241-302 (tom qab tempering)	GB/T 231.1-2018
