ʻO W6Mo5Cr4V2(M2) nā kaola kila ʻōwili wela

ʻO M2 ka molybdenum molybdenum kiʻekiʻe-wikiwiki kila, loaʻa nā pono o ka inhomogeneity carbide liʻiliʻi a me ka paʻakikī kiʻekiʻe. ʻO ka maʻalahi o ka overheating, pono e hoʻomalu pono i ka wela wela, ʻoi aku ka palekana o ka mālama wela. Ma muli o kona paʻakikī a me ka hiki ke hoʻohana ʻia, hoʻohana ʻia i ka hana ʻana o ka ʻoki ʻana i ka paʻakikī o ka ʻoki ʻana i nā mea paahana. ʻOi aku ka nui o ke kila kiʻekiʻe M2 me ka carbide orientation, no laila ʻoi aku ka paʻakikī o ka mālama ʻana i ka wela no ka haʻalulu a me nā haʻalulu haʻalulu.

SAE M2 Mea Paahana Steel Material Mechanical Properties

ʻO ka paʻakikī, Rockwell C (ua wela ma 621°C, kinai ʻia ma 1204°C): 62 HRC.

Paʻakiki, Rockwell C (hoʻopiʻi ʻia ma 1204°C) ): 65 HRC
