A105 mea kila paipu

ʻO A105 ka helu maʻamau o ʻAmelika ASTM, a ʻo A ke kila kila maʻamau.
inoa maʻamau: kalapona kila forgings no ka paipu.No ka mea, hoʻokahi wale nō kalapona kalapona kalapona i kuhikuhi ʻia i loko o kēia maʻamau, ʻo A105 ʻo ia hoʻi kahi pae kila kalapona o ka forging.ʻO A105 kekahi code waiwai, nona ke kila kūikawā a he kila hoʻoheheʻe ʻia.ʻO A105 kahi hao kalapona haʻahaʻa e hoʻoheheʻe ʻia, e like me 20 kila.ʻElua mau kūlana, hoʻokahi ka American standard ASTM A105/A105M Carbon Steel Forgings for Piping Components, a ʻo kekahi ʻo ka China standard GB/T12228-2006 Technical Conditions for Carbon Steel Forgings for General Purpose Valves.
Hui C: ≤ 0.35 Si: ≤ 0.35 Mn: 0.6-1.05 S: ≤ 0.050 P: ≤ 0.040, Cu ≤ 0.4 Ni ≤ 0.4 Mo ≤ 0.12 V ≤ 0.08 Cr 3.0
ʻO nā waiwai mechanical ma waena o No. 20 forged steel a me 16Mn forged steel.
