A105 mea uamea paipa

O le A105 o le numera masani a Amerika ASTM, ma o le A o loʻo faʻatusalia le uamea faʻapipiʻi masani.
Igoa masani: u'amea u'amea forgings mo vaega paipa.Talu ai na o le tasi le carbon steel forging ua faʻamaonia i lenei tulaga, A105 e oʻo lava i le carbon steel grade of forging.O le A105 foi o se mea faʻapitoa, lea e patino i le sila faʻapitoa ma o se uʻamea malulu malulu.A105 o se u'amea maualalo kaponi forging, tutusa ma 20 sila.E lua tulaga, o le tasi o le American standard ASTM A105 / A105M Carbon Steel Forgings mo Piping Components, ma le isi o le Chinese standard GB / T12228-2006 Tulaga Faʻapitoa mo Carbon Steel Forgings mo Valves Faʻamoemoega Lautele.
Tulaga 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
O mea fa'ainisinia o lo'o i le va o le sila Numera 20 ma le sila 16Mn.
