ʻO CrWMn nā kaola kila ʻōwili wela

CrWMn make kila papa mea paahana kila, aila quenching haʻahaʻa deformation anu hana make steel.The kila wearability, ma muli o ka hui 'ana i ka lehulehu hakina o 1.20% ~ 1.60% o tungsten, hana carbide no laila ma hope o quenching a me ka haʻahaʻa wela e loaʻa ⼀ paakiki a abrasion resistance.Tungsten kokua i ka malama i na hua maikai mai ka hana ana i ke kila i oi aku ka pliable.The steel is sensible to forming carbon, which can cause the blade spalling.Although ka ikaika, paakiki a me ka oolea o ke kila. loaʻa nā hemahema e like me ka maʻalahi a me ka wili ʻana ma muli o ka carbide segregation. ʻO ke kinai ʻana i ke kila kalapona, a ua hoʻemi ʻia ka laulā noi. ʻO ka paʻakikī a me ke kūpaʻa abrasion o ke kila a me ka paʻakikī o ke kila chromium a me ke kila silikona chromium ma hope maikai ke kinai ana, a maikai ka oolea.
ʻAʻole hiki i ka CrWMn ke hoʻohana nui ʻia no ke kila kila kila i nā koi o ka ʻāpana keʻa nui, ʻoi aku ka paʻakikī o ke ʻano o nā ʻāpana make, koi liʻiliʻi i ka deformation quenching.
1) Hoʻohana nui ʻia kēia ʻano kila i ka hana ʻana i ke kila lahilahi, ka metala non-ferrous, nā mea kumu o ka ukana māmā a me ke ʻano paʻakikī o ka make ʻana o ke anu, ʻoi aku ka nui o nā ʻano o ka uaki, nā mea kani, nā mea pāʻani a me nā ʻoihana huahana, etc. ʻAʻole kūpono ka pale ʻana i ka pā kila austenite, ka pepa kila silika a me ka pā kila ikaika kiʻekiʻe.

2) hiki ke hoʻohana ʻia ka mānoanoa o ke kila no ka hana ʻana i nā mea <1 mm o ka blanking die complex shaped punch, concave die, set piece, a me nā ⼀ strands of deep drawing die. Manaʻo ʻia ka hana ʻana o Punch i ka 58 a i ka 62 HRC paʻakikī, a ʻo ka concave mold production i manaʻo i ka paʻakikī 60 ~ 64 HRC.

3) Hoʻohana ʻia ia no ka hoʻokomo ʻana i ka punch die me ke kūpaʻa ʻaʻahu kiʻekiʻe a me ke ʻano paʻakikī i ka make ʻana. ʻO ka paʻakikī o ka punch make e ʻōlelo ʻia he 58 ~ 62HRC a ʻo 60-64hrc e ʻōlelo ʻia he 60-64hrc i ka wā e make ai ka punch.

4) A convex make a concave make no ke anu extrusion make o alumini parts.The paakiki o 60 ~ 62HRC ua paipai 'ia no punch make a me 62 ~ 64HRC no ka punch make.

5) No ke anuanu extrusion make o nā ʻāpana keleawe a me ke anuanu extrusion make a make i nā ʻāpana kila, ʻo ka paʻakikī i ʻōlelo ʻia ʻo 62-64hrc.

6) Ma hope o ka hana ʻia ʻana, hiki ke hoʻohana ʻia e hana i nā ʻāpana veneer nui i hoʻohana ʻia ma nā mīkini kaomi ʻoi aku ma mua o 1mm, e hoʻonui pinepine i ka paʻakikī o ke kila i 50-55hrc. Eia nō naʻe, pono e hōʻemi ʻia a pale ʻia paha nā hemahema o ka ʻiʻo e like me ka banded carbide structure a i ʻole chromatography wai.
