H13 Tuam Txhab Hlau Phaj Kev Muag Khoom

AISI H13 Kub ua hauj lwm cuab yeej hlau (TIAB SA 1.2344) yog cov cuab yeej steel qib txheem rau kev ua haujlwm kub. Cov yam ntxwv tseem ceeb ntawm qib no yog kev sib xyaw ua ke ntawm cov ntsiab lus alloyed ntawm Cr, Mo thiab V, uas muab kev hnav zoo rau thermal shock. Nws paub zoo tias nws lub zog loj, thiab kub ua haujlwm. Nws yog siv ntau rau tuag casting nyob rau hauv lub caij txias heading teb. Lub xub ntiag ntawm high vanadium nyob rau hauv DIN 1.2344 tuaj yeem tswj qhov puas ntawm qhov kub thiab txias. Nws yeej ib txwm muab ib tug uniform thiab siab ntawm machinability. Cov cuab yeej hlau no feem ntau yog siv rau txhuas, magnesium thiab zinc tuag casting.

H13 Tsim Dimensions

Round: dia 10-700 hli
Pav ca: 6-120 x 40-1200 mm
Thaiv: 80-600 x 100-1600 mm

Yam ntxwv
1. Cua txias hardened kub ua hauj lwm cuab yeej steel, feem ntau lug siv.
2. High toughness Zoo txias & thermal qaug zog tsis kam.
3. Me me distortion, deformation thiab oxide daim tawv nqaij tom qab kev kho cua sov thaum lub sij hawm cua txias.
4. Zoo tiv thaiv los ntawm undermining ntawm fusing Aluminium.

Forging Technique

Kev kho cua sov

Annealing
750 txog 800 degree (1382 txog 1472 degree F)
Kev tswj kom txias qeeb hauv qhov cub ntawm tus nqi ntawm 10 txog 20 degree / hr (50 txog 68 degree F / hr) mus rau
kwv yees. 600 degree (1112 degree F), ntxiv txias hauv huab cua.
Hardness tom qab annealing: max. 235 HB.

Hardening
1020 txog 1080 degree (1868 txog 1976 degree F)
Roj, ntsev da dej (500 - 550 degree / 932-1022 degree F), cua
Tuav lub sij hawm tom qab kub sib npaug: 15 mus rau 30 feeb.
Tau txais hardness:
52 - 56 HRC hauv roj lossis ntsev da dej,
50 - 54 HRC hauv huab cua.
Kev ntxhov siab
600 txog 650 degree (1112 txog 1202 degree F)
Ua kom txias qeeb hauv qhov cub; npaj los txo kev ntxhov siab los ntawm kev siv tshuab dav dav, lossis hauv cov duab nyuaj.
Tom qab ua cua sov, tuav hauv nruab nrab cua rau 1 - 2 teev.

Tempering
Ua cua sov qeeb rau tempering kub tam sim ntawd tom qab hardening / sij hawm nyob rau hauv qhov cub
1 teev rau txhua 20 hli ntawm workpiece thickness, tab sis tsawg kawg yog 2 teev / txias hauv huab cua.
Nws raug nquahu kom npau taws tsawg kawg ob zaug.
Ib lub voj voog thib peb rau lub hom phiaj ntawm kev txo kev ntxhov siab tuaj yeem ua tau zoo.
1st tempering approx. 30 degree ({2}} degree F) siab tshaj qhov siab tshaj plaws thib ob hardness.
2nd tempering rau qhov xav tau ua haujlwm hardness.
Daim ntawv qhia tempering qhia qhov nruab nrab tempered hardness qhov tseem ceeb.
3rd rau kev ntxhov siab ntawm qhov kub ntawm 30 - 50 degree (86 txog 122 degree F) qis tshaj plaws
tempering kub.

Daim ntawv thov

● Rau kev ua txhuas thiab tooj liab alloy tuag casting pwm thaum tuag kab noj hniav kub yog qis dua 600 degree

● Rau kev ua forging tuag, forging xovxwm pwm, pwm rauj thaiv kom zoo forging tshuab siv.
