P275N Pressure Vessel Steel Plate

EN10028 P275N simbi ndiro/sheet, pasi peEN chiyero, tinogona kutarisa P275N simbi ndiro/sheet remaboilers uye Pressure Vessels steels. EN10028 P275N simbi ndiro/sheet ndeye boilers uye Pressure Vessels simbi, chinhu chakajairika. simbi ndiro uye pepa iro rinonyanya kushandiswa kuvaka kumanikidza midziyo uye boilers uye pombi dzemvura inopisa.

Pasi pechiyero EN10028_3,ndiro yesimbi P275N ichave iri pasi peNormalized delivery condition painogadziriswa.Izi simbi giredhi P275NH neP275N inonyanya kushandiswa mumidziyo yekumanikidza uye maboilers inosiyana kubva kune mamwe carbon_manganese structural simbi ndiro dzine kupikisa kwayo kukuru kumanikidziro patembiricha yose kana ichishandiswa.
