GENERAL
Txawm hais tias muaj cov pa roj carbon ntau, cov ntsiab lus hlau nyob rau hauv cov ces kaum me me los ua kom cov hlau tsis muaj zog hauv kev lees paub, ncav cuag hardness ntawm 57 txog 62 HRC tom qab tempering. Nws muaj cov yam ntxwv zoo ntawm machinability, hnav tsis kam thiab polishing teb.
Chemical composition – C ({{0}}.95) • Mn (1.2) • Cr (0.5) • W (0.5)
Supply conditions – It is supplied in an annealed state with a hardness of 200HB approx.
APPLICATIONS
Kev siv ntawm Gnee O1 steel yog siv rau hauv cov ntawv txias thiab peripheral daim ntaub ntawv thiab cov cuab yeej, uas yuav tsum tau hnav tsis kam, tshwj xeeb tshaj yog nyob rau hauv lub hnub txiav. Nws feem ntau yog siv hauv steelworks rau cov uas tsis yog -ferrous hlau thiab hlau, cov cuab yeej siv rau kev ua haujlwm ntawm cov ntoo, cov plooj (porcelain matrices), ntsuas cov cuab yeej uas muaj qhov ruaj khov siab, xws li hardness gauges, cov qauv, cov cai, xyaum, txiab, lub kaum sab xis grinders. txias, cutters, punches, phem, Split tuag.
KEV KHO MOB
Kev ntxhov siab: Hauv cov cuab yeej ntawm cov duab nyuaj, tshem tawm cov khoom siv sib txawv hauv kev ua kom nyias nyias, hloov pauv sai sai hauv ntu, thiab lwm yam, kev kho kev ntxhov siab yuav tsum tau ua kom txo qis qhov sib txawv ntawm qhov sib txawv thiab cov duab thaum lub sij hawm quenching thiab tempering. Kev kho mob yuav tsum nyob nruab nrab ntawm 500 thiab 600 degrees tsawg dua ob teev thiab tom qab ntawd maj mam txias ntawm 300 degrees thiab tom qab ntawd txias.
Temple: Precalentar el horno to 600 degree C. Austenize from temperature between 790 – 820 degree and cool in water. Heat for 1 hour for every 25 mm of thickness and add 1 additional hour for every 25 mm. Accept cold heat with agitation, air in rest in a bath of molten salt at approximately 200 degree C. Then cool the air in calm.
Template : It must be done immediately after the temple when the temperature reaches approximately 70ºC The temperature of the template must be selected according to the specified hardness. As this steel does not have secondary hardening, tempered it must be around 200 degree during hardness between 59-61 HRC, but never below 180 degree . For this use as a guide below the curve of the temple. Keep at the tempering temperature for at least 1 hour for every 25 mm of thickness. The use of a minimum of 2 hours. The double tempered is recommended for greater dimensional stability.
Cooling at 820ºC. tempered twice of 2 hours each.
EDM and milling: The Gnee O1 steel is susceptible to the appearance of cracks after these processes. When carrying out outside the box, the electroerosion and rectification may cause surface retemper, the deterioration of the heat treatment in the region and give rise to the formation of cracks. In extreme cases it can cause la pérdida de la herramienta. It is important to remove the tempered layer before using it. Preferably build a new temple after finishing the tool for stress relief. In this case the temperature is 50 degree lower than the tempering.Temperature of 820 degree . tempered twice of 2 hours each.
