DIN 1.6580 / 30CrNiMo8 30cr2ni2mo alyaj ba asye

Alman DIN estanda 30CrNiMo8 se asye tanpere, ekivalan a Lachin 30Cr2Ni2Mo.

karakteristik 30crnimo8 gen fòs segondè segondè, fòs tansib ak fatig fòs, osi byen ke ase plastisite ak severite. Editè metòd editè Jeneralman, fouro elektrik ak oksijèn tèt konvètisè tèt yo adopte pou smelting, pandan y ap rafine ekstèn, elektwosklag remelting oswa tretman vakyòm, endiksyon vakyòm fouye oswa doub vakyòm sant ak apwopriye tretman chalè yo adopte pou moun ki gen kondisyon segondè.

aplikasyon 1.6580 30crnimo8 se lajman ki itilize nan veso presyon ki wo ak presyon segondè ak fluctuation souvan, men tou, nan tiyo presyon, mwazi plastik, estrikti enpòtan ak sou sa. Pou egzanp, arbr prensipal la nan FD70A ak FD77A van turbine ansanm nan faktori vapè turbin adopte-wo kalite asye (30CrNiMo8) fòje
