DIN 1.2714 L6 Caaryada Birta
Sharaxaad Gaaban:
1.2714 waa nooc ka mid ah qalabka birta, sidoo kale loo yaqaan L6 steel. Waxaa lagu gartaa adkeysigeeda heer sare ah, adkeysi sare leh, iyo iska caabin wanaagsan oo xirashada, taasoo ka dhigaysa mid ku habboon codsiyada kala duwan ee soo saarista dhinta been-abuurka ah, dhinta-dhimista, iyo aaladaha kale ee saameyn culus iyo xirashada.
DIN 1.2714 L6 Birta Caaryada:
Biraha birta ah ee laga sameeyay 1.2714 alloy ayaa inta badan lagu bixiyaa xaalad la jeexjeexay, taas oo u oggolaanaysa mashiinnada fudud iyo daaweynta kulaylka xiga. Waxaa lagu daweyn karaa kulaylka si loo gaaro qallafsanaanta la doonayo iyo heerarka adag ee ku habboon codsiga loogu talagalay. Sida qalabka kale ee qalabka, 1.2714 birta waxay u baahan tahay daaweyn kuleyl ah oo habboon si kor loogu qaado waxqabadkeeda. Tani waxay ku lug yeelan kartaa habab ay ka mid yihiin xinjirowga, deminta, iyo xanaaqa, iyadoo ku xiran sifooyinka la rabo. Birtan caadi ahaan waxay ka kooban tahay walxo ay ka mid yihiin chromium, nikkel, iyo molybdenum, kuwaas oo gacan ka geysta sifooyinkeeda farsamada. Magacaabista "1.2714" waa kood lambareed loo isticmaalo in lagu aqoonsado halabuurka gaarka ah iyo sifooyinka birta.
