60Si2Mn wela olokaa kila poepoe kaola

ʻO ke kila puna 60Si2Mn he kila puna silico-manganese i hoʻohana nui ʻia me ka ikaika iki, elasticity a me ka paʻakikī ma mua o 55Si2Mn. ʻO 60Si2Mn ʻoihana kila punawai e hoʻopuka i nā pūnāwai pālahalaha me ka ukana nui a i ʻole nā ​​pūnāwai coil me ke anawaena ma lalo o 30mm. He kūpono hoʻi ia no ka hana ʻana i nā pūnāwai pale wela me ka mea ʻaʻohe corrosive me ka mahana hana ma lalo o 250 °C a me nā haʻahaʻa ʻokoʻa a me ke koʻikoʻi kiʻekiʻe. ʻO nā pūnāwai coil koʻikoʻi nui no ka hana ʻana ma lalo, a me nā ʻōnaehana hoʻoheheʻe automotive.

Mea Kimia:

C(%)	Si(%)	Mn(%)	P(%)	S(%)	Cr(%)	Ni(%)	Cu(%)	Ke koʻikoʻi hua (Mpa)	ʻO ke kaumaha (Mpa)	Elongation (%)

Nā waiwai mīkini:

Ka ikaika wili σb (MPa): ≥ 1274 (130)
Ka ikaika hua σs (MPa): ≥1176 (120)
Elongation δ10 (%): ≥5
Hoʻemi ʻāpana ψ (%): ≥25
Paʻakikī: ka'ōwili wela, ≤321HB; kaha kiʻi anu + mālama wela, ≤321HB

Hōʻike wela:

60Si2Mn wela lāʻau kiko'ī: quenching 870 °C ± 20 ° C, aila hooluolu; ka hoʻoheheʻe ʻana 480 ° C ± 50 ° C (pono kūikawā, ± 30 ° C).
ʻO ka hui metallographic: tempered troostite.

Ke kūlana hoʻouna: Hāʻawiʻia ke kila wela i ka wela a iʻole ka wela wela, a hāʻawiʻia ke kila anuanu ma ke kūlana wela.
ʻO nā kikoʻī hāʻawi ʻōwili wela: 2.0 ~ 18.0mm, me ka ʻole o ka annealing. ʻO nā kikoʻī o ka hāʻawi ʻana i ke anuanu: 0.3 ~ 4.3mm (mea hao)

ʻano hoʻomaʻamaʻa wela

ʻO 60Si2Mn nā hana lapaʻau wela ka isothermal tempering a me ka grading quenching, sub-temperature quenching a me ka wela wela kiʻekiʻe, deformation wela kaʻina hana. Hiki i ke ala ke hoʻomaikaʻi maikaʻi i ka ikaika a me ke ola lawelawe o 60Si2Mn puna kila. No ke kila puna ka 60Si2Mn, kūpono no ka hana ʻana i ka puna lau kaʻa. 60Si2Mn pūnāwai kila wela lapaʻau isothermal tempering a me grading quenching, sub-mahana quenching a me kiʻekiʻe wela tempering, deformation wela kaʻina hana. Hiki i ke ala ke hoʻomaikaʻi maikaʻi i ka ikaika a me ke ola lawelawe o 60Si2Mn puna kila.

mānoanoa

60Si2Mn mānoanoa o 7.85g / cm3. 60Si2Mn ua hoʻohana nui ʻia ke kila manganese puna kila, ikaika, elasticity a me ka paʻakikī ma mua o 55Si2Mn kiʻekiʻe iki. He kūpono no nā kaʻa kaʻaahi, ʻoihana tractor kaʻa e hana i kahi haʻahaʻa nui o nā pūnāwai palahalaha a i ʻole ke anawaena uea o 30mm ma lalo o ka puna coil.
