4 cr13tus qauv: GB/T 1220-1992. 4Cr13 yam ntxwv yog siab dua 3Cr13 hardness thiab zoo corrosion kuj tom qab quenching.
4Cr13 steel phaj tshuaj muaj pes tsawg leeg:

C	Si	Mn	S	P	Cr	Ni
0.36~0.45	Tsawg dua lossis sib npaug rau 0.60	Tsawg dua lossis sib npaug rau 0.80	Tsawg dua lossis sib npaug rau 0.030	Tsawg dua lossis sib npaug rau 0.035	12.00~14.00	Tsawg dua lossis sib npaug rau 0.60

4 cr13steel phaj mechanical khoom
Hardness: annealing, tsawg dua 201HB, indentation txoj kab uas hla 3.9 ~ 4.3mm; quenching, ntau tshaj 50HV
Specification thiab metallographic qauv ntawm kev kho cua sov:
Cov lus qhia tshwj xeeb rau kev kho cua sov: 1) annealing ntawm 800 ~ 900 DEG C lossis chilled ntawm 750 DEG C; 2) quenching, 1050 ~ 1100 DEG C, roj txias. (3) Tempering, ceev txias ntawm 200 ~ 300 DEG C.
Microstructure: lub microstructure yog tus cwj pwm los ntawm Martensite.

Tus me nyuam raws li txoj cai: 4Cr13 steel phaj yog xa nyob rau hauv annealed mob. Forging: roj quenching rau qee qhov tawg rhiab heev ntawm cov hlau tuag, forging cua sov kom ceev cua sov, nyiam dua preheating hauv 650-750 degrees, forging kub yog 1130-1150 degrees, qhov kawg forging kub yuav tsum siab tshaj {{4} } } degrees, qhov siab tshaj plaws kub ntawm ingot forging. Qhov ntsuas kub qis dua yuav tsum tau noj thaum lub sijhawm forging.

Gnee steelyog tshwj xeeb hauv kev muab 4Cr13 steel phaj. Peb muaj 17 xyoo dhau los hauv kev xa tawm ntawm 4Cr13 steel phaj. Thov koj xav tiv tauj peb.

Kev kho cua sov ntawm 4Cr13 steel

1. Kev sib tw
750 txog 800 degree rau li 2 mus rau 5 teev
qeeb tswj cua txias ntawm 10 txog 20 degree ib teev mus txog 650 degree;
ntxiv txias hauv huab cua, max. 200 HB

2. Hardening
1000 rau 1050 degree
15 mus rau 30 feeb kom curing kub
quenching hauv roj / compressed roj / da dej kub
Tau txais hardness: 53-56 HRC

3. Kub kub
qeeb cua sov kom tempering kub tam sim ntawd tom qab hardening, mus rau 180 mus rau 300 degree nyob ntawm seb xav tau hardness
1h rau 20 mm:m. 2 teev
