Letlapa la tšepe la P460NH la Khatello

P460NH, eo ho thoeng ke ho ba le matla a bonyane a tlhahiso ea 460 MPa, ke boemo bo phahameng ba khatello ea sejana sa tšepe se sebelisoang ha ho etsoa boiler le ho etsoa ha sekepe sa khatello. Ke tšepe ea lijo-thollo e tloaelehileng e nang le litšobotsi tse ntle tsa weldability.
