Cov yam ntxwv ntawm H21 tuag steel:
Cov seem steel tuaj yeem ua kom tawv hauv qab 80mm. Qhov no yog txaus rau cov txheej saum npoo yuav tsum tau loj saum forging tuag, kub nias tuag thiab ca forging tshuab tuag nrog siab hardness thiab siab hnav tsis kam. Cov hlau no muaj qhov kub hloov pauv siab thiab zoo thermal qaug zog tiv thaiv qhov txias thiab kub hloov pauv. Cov hlau no tuaj yeem siv los ua cov punch thiab tuag nrog kev ntxhov siab nyob rau hauv qhov kub thiab txias, tab sis tsis cuam tshuam rau kev thauj khoom, xws li xuas nrig ntaus thiab tuag siv lub tshuab forging, ntxig, tooj liab alloy extrusion tuag, tuag casting tuag, xws li rov qab extrusion tuag; Nws kuj tseem siv tau los ua cov hlau kub kub hauv qab kub. Tungsten-muaj kub-ua haujlwm tuag hlau, uas ua rau cov ntsiab lus ntawm Mo los ntawm 2 feem pua, thiab ntxiv cov ntsiab lus ntawm Mn kom txhim kho qhov kub thiab txias ntawm cov hlau, thiab ua tau raws li qhov xav tau ntawm cov khoom loj ntawm aluminium alloy tuag-casting. pwm. Cov hlau muaj lub zog thermal, siab thermal stability, zoo hnav tsis kam thiab thev naus laus zis, thiab ua haujlwm kub txog 650 degree
H21 steel, tungsten uas muaj cov haujlwm kub tuag steel, muaj ntau cov chromium thiab tungsten cov ntsiab lus uas yooj yim rau kev tsim carbides, yog li nws muaj zog thiab hardness ntawm qhov kub thiab txias, thiab nws hardness ncav cuag HB-300 ntawm 650 degree. , tab sis nws toughness thiab plasticity tsis zoo.
