Khoom Taw qhia

H13 steel yog qhov nrov tshaj plaws thiab muaj ntau yam, ua haujlwm kub pwm hlau, muab qhov sib npaug zoo ntawm cov tawv nqaij, tiv thaiv tshav kub, thiab kub siab zog, ntxiv rau kev hnav tsis kam. H13 steel tuaj yeem tiv taus softening rau 550 degree thiab muaj kev tiv thaiv zoo rau kev ntsuas kub. Yuav Nitride nrog cov ntaub ntawv hardness tshaj 1000 VPN Feem ntau muab annealed rau HB 230 max.

Kev kho saum npoo
Vim tias nws qhov kub thiab txias (1000 F), H13 steel yuav raug kho los ntawm cov txheej txheem kho saum npoo feem ntau, suav nrog cov pa thiab ion nitriding, titanium nitriding, thiab lwm yam txheej txheem lossis kev kho mob. Nitrided nto hardness yuav yog 60/65 HRC.

Txheej txheem
H13 cov khoom yog softer thaum lub sij hawm kub forging, thiaj li yuav zam dhau heev bending, qhov ntev ntawm cov cav tov zoo tib yam tsis ntau tshaj 9 meters, nyob rau hauv cov ntaub ntawv ntawm Radial forging khoom, lub H13 steel forging rounds bar tuaj yeem ncav cuag qhov siab tshaj plaws ntawm 15 meters. .
Hauv kev tsim khoom, H13 ingots xav tau maj mam txias. Tom qab ingot tso pwm, nws yuav tsum tau siv annealed ua ntej forged.
Raws li kev xa khoom rau cov neeg siv khoom, H13 pom zoo kom annealing ntxiv rau saum npoo ci ( tshem tawm cov tawv nqaij dub oxide), vim tias cov nickel siab yog qhov ua rau tawg.

Daim ntawv thov
H13 steel yog cov cua hardening, 5 feem pua chromium tuag steel, uas yog ib qho kev xaiv zoo heev rau ntau yam kev ua haujlwm kub thiab kev ua haujlwm txias. Cov ntawv thov muaj xws li tuag casting tuag rau txhuas, magnesium thiab zinc, extrusion tuag rau txhuas thiab tooj dag, liners, mandrels, siab pads, followers, bolsters, tuag rooj, tuag tuav thiab adapter rings rau tooj liab thiab tooj dag extrusion. H13 steel yog siv los tsim kub stamping thiab xovxwm forge tuag, cais kub taub hau tuag, gripper tuag, kub xuas nrig ntaus, tho thiab trimming cov cuab yeej. Lwm yam kev siv xws li yas pwm, shear blades rau kub ua hauj lwm thiab kub swaging tuag.
