Ipleyiti yentsimbi yentsimbi yeP275N

EN10028 P275N ipleyiti yentsimbi / ishidi, phantsi komgangatho we-EN, sinokujonga ipleyiti yensimbi ye-P275N / ishidi yeebhoyila kunye ne-Pressure Vessels steels. ipleyiti yentsimbi kunye neshiti elisetyenziselwa ikakhulu ukwakha iinqanawa zoxinzelelo kunye neebhoyila kunye nemibhobho yolwelo olushushu.

Phantsi komgangatho we-EN10028_3,ipleyiti yentsimbi P275N iya kuba phantsi kwemeko yonikezelo oluQhelekileyo xa kusetyenzwa.Olu didi lwentsimbi lwe-P275NH kunye ne-P275N lusetyenziswa ikakhulu kwiinqanawa zoxinzelelo kunye nezibiyile zohluke kwezinye iipleyiti zentsimbi ze-carbon_manganese ezinokumelana noxinzelelo oluphezulu kuwo onke amaqondo obushushu xa zisetyenziswa.
