Birta Qaabaynta DIN 1.2714 L6
Sharaxaad Gaaban:
1.2714 waa nooc ka mid ah birta qalabka birta ah, oo sidoo kale loo yaqaan birta L6. Waxaa lagu gartaa adkeysigeeda aadka u wanaagsan, adkaanta sare, iyo iska caabbinta xirashada wanaagsan, taasoo ka dhigaysa mid ku habboon codsiyada kala duwan ee soo saarista maydadka been abuurka ah, maydadka lagu shubo maydadka, iyo qalabka kale ee la kulma saameyn iyo xirasho culus.
Birta Qaabaynta DIN 1.2714 L6:
Birta laga sameeyay birta 1.2714 waxaa badanaa lagu bixiyaa xaalad annealed ah, taasoo u oggolaanaysa farsamayn fudud iyo daaweynta kulaylka dambe. Waxaa lagu daweyn karaa kulaylka si loo gaaro heerarka adkeysiga iyo adkaanta la rabo ee ku habboon codsiga loogu talagalay. Sida birta kale ee qalabka, birta 1.2714 waxay u baahan tahay daaweyn kuleyl oo habboon si loo kordhiyo waxqabadkeeda. Tani waxay ku lug yeelan kartaa hababka sida annealing, deminta, iyo tempering, iyadoo ku xiran sifooyinka la rabo. Birtan waxay caadi ahaan ka kooban tahay walxo sida chromium, nickel, iyo molybdenum, kuwaas oo gacan ka geysta sifooyinkeeda farsamada. Magaca "1.2714" waa lambar tiro ah oo loo isticmaalo in lagu aqoonsado halabuurka gaarka ah iyo sifooyinka birta.
