Ntawm no yog cov ncauj lus kom ntxaws saib ntawm25Cro4, 34CRRRO4, thiab 42CRMO4 lub zog qis alloy hlau daim hlau, tsom mus rau lawv muaj pes tsawg leeg, cov khoom, kev siv, thiab cov kev qhia tshwj xeeb:

1. Kev Rov Ntxiv thiab Tshuaj Lom Zem

Cov qhab nia rauEuropean en 10083-3Txheem rau quenched thiab tempered alloy hlau. Cov kev paub npe hu ua:

 

Cov lej (25\/34\/42): Kwv yees cov ntsiab lus carbon cov ntsiab lus ({{0}}}}}}. 34%, 0.42%).

Crroco4: ~ 1% chromium (CR) thiab ~ {0. 25% molybdenum (mo) raws li cov ntsiab lus tseem ceeb.

 

Teem nqi	C	Si	Mn	Cr	Mo	P \/ s (max)	Cov yam ntxwv tseem ceeb
25Cro4	0.22-0.29	0.15-0.40	0.60-0.90	0.90-1.20	0.15-0.30	0.025	Cov pa roj carbon, siab nruj thiab weldability
34QRO4	0.30-0.37	0.15-0.40	0.60-0.90	0.90-1.20	0.15-0.30	0.025	Ntsuas lub zog thiab hnav tsis kam
42Crmo4	0.38-0.45	0.15-0.40	0.60-0.90	0.90-1.20	0.15-0.30	0.025	Muaj zog, zoo tagnrho rau cov ntawv thov hnyav-plaub hau

 

Qhov tseem ceeb alloy luag hauj lwm:

 

Cr: Txhim kho hardness, corrosion kuj, thiab cov tawv me.

Mo: Txhim kho kom muaj zog kub-zog, tiv thaiv kev npau taws txias, thiab boosts hnav tsis kam.

Nruab nrab-cov pa roj carbon ntau: Cov zog nce tensile thiab hardness (tshwj xeeb tshaj yog nyob rau 34 \/ 42crmo4).

 

 

 

Cov Kev Siv Raug Raug

(1) 25Crmo4

Cov ntawv thov qis-rau-nruab nrab:

Welded qauv: Cov nkoj siab, cov kav dej, thiab boiler cov khoom siv (vim yog Weldability zoo).

Automotive: Kis Shaft, zog, thiab kauj knuckles hauv cov tsheb me.

Txuas lub zog txuas ntxiv: Cua Turbine Hub Sib Txuas yuav tsum muaj kev nruj.

(2) 34crmo4

Nruab Nrab-rau-Hnyav Cov Kev Siv Hnyav:
