Letlapa la tšepe la P460N la Khatello

P460N tšepe kereiti ke e 'ngoe ea grade ho En10028-3, eo e seng alloy le litšepe tsa alloy tse nang le thepa e phahameng e phahameng ea mocheso. Limaraka tsa P460N li sebelisoa ka holim'a tsohle bakeng sa ho etsa li-boilers, likepe tsa khatello le liphaephe tse tsamaisang metsi a chesang.

Sehlopha sa tšepe sa EN10028 se feta maemo a khale a BS le DIN.


Tšebeliso ea mantlha:
EN10028-3 P460N Sejana sa Khatello le Boiler Steel Plate li sebelisoa ka Sekopeng sa Khatello, Boiler, Litanka tsa polokelo le Mocheso oa Mocheso ka Oli, Morero oa Khase.
