H13 Kub ua hauj lwm cuab tam Steel Bar Chaw muag khoom
Hom: Phaj / Round Bar / Flat Bar
Khoom Description
H13 yog kub ua haujlwm tuag hlau, kev ua raws li tus qauv GB / T1299-2000. ; Qib 4Cr5MoSiV1; alloy cuab yeej steel hu ua cov hlau sib koom ua ke, carbon steel yog raws li qhov sib ntxiv ntawm cov ntsiab lus alloying thiab tsim cov hlau. Ntawm lawv, suav nrog: ntsuas cov cuab yeej nrog cov cuab yeej txiav, cuam tshuam cov hlau, ua haujlwm txias tuag steel, kub tuag steel, tsis muaj hlau nplaum hlau, yas pwm hlau.
A. Electroslag remelting steel, cov hlau muaj lub siab hardenability thiab thermal cracking kuj,
B. Muaj cov ntsiab lus ntau dua ntawm cov pa roj carbon thiab vanadium, zoo hnav tsis kam, toughness kuj tsis muaj zog, nrog rau cov cua sov zoo.
C. Kub kub nrog zoo zog thiab hardness, siab hnav kuj thiab toughness,
D. Cov khoom siv zoo heev thiab kev ua haujlwm siab rau tempering stability.
1.Full hardness (52-54HRC) yas pwm uas yuav tsum tau ntau dua rau polishing thiab ntev, xws li Bakelite yas pwm.
2. Tuag casting pwm ntawm txhuas, zinc thiab txhuas alloy (xws li cav radiator, teeb, thiab kho kom zoo nkauj).
3.Aluminium extrusion pwm xws li Aluminium qhov rai & qhov rooj, lub computer radiator.
4. Kub forging pwm xws li pib txuas rods, crank, stainless noj hmo riam.
5.Low yielding cooper thiab aluminium alloy extrusion thiab tuag casting pwm.

Kev kho cua sov ntawm H13 / 1.2344 / SKD61 steel
Kub txoj kev
Forging: 1100 txog 900ºC, qeeb txias hauv qhov cub.
Annealing: 750 txog 800ºC, qeeb txias hauv qhov cub (10-20ºC / hr), nqis mus rau 600ºC, txias hauv huab cua. Hardness tom qab annealing: max. 230 HB.
Kev ntxhov siab: 600 txog 650ºC, qeeb qeeb hauv qhov cub. Tuav hauv nruab nrab qhov chaw rau 1 mus rau 2 teev.
Hardening: 1020 txog 1080ºC, roj / cua, tuav 20 mus rau 30 feeb. Hardness, 52 txog 56 HRC hauv roj, 50 txog 54 HRC hauv huab cua.
Kub kub: 560-580ºC. Maj mam cua sov rau tempering kub txoj cai tom qab hardening. Pom zoo kom npau taws tsawg kawg ob zaug. Qhov thib ob tempering kub yuav tsum yog approx. 20 txog 30ºC qis dua thawj tempering.
