NM400 /NM 450 e roala poleiti ea tšepe ea ho hanyetsa
NM450 ke poleiti ea ho roala e matla haholo.
Ho reha lebitso: N ke ea khanyetso (nai), M ke tlhaku ea pele ea pinyin ea litlhaku tse peli tsa Sechaena bakeng sa ho sila (mo),
'me 450 e emela boima bo tloaelehileng ba Brinell ba poleiti ena ea tšepe
Phekolo ea mocheso: mocheso o phahameng oa mocheso, ho tima + ho futhumatsa (ho tima le ho kokobetsa)
Kopo: Letlapa la tšepe le sa sebetseng la NM450 le sebelisoa haholo mecheng ea merafo, mechini ea merafo ea mashala,
mechine e sireletsang tikoloho, mechine ea kaho, joalo-joalo, 'me e boetse e sebelisoa ka tloaelo e le matla a phahameng
tšepe ea sebopeho e nang le matla a tlhahiso ≥850MPa.
Mosebetsi: Ke haholo-holo ho fana ka tšireletso liketsahalong kapa likarolo tse hlokang ho hanyetsoa, e le hore bophelo ba
thepa e telele, ho theoha ha nako ea tlhokomelo e bakoang ke tlhokomelo e fokotsehile, le lichelete tsa lichelete
e fokotsehile joalo.
Ts'ebetso: Lihlahisoa li feta 950, 'me matla a thata ke 1180.
NM450 e lumellana le litekanyetso le litekanyetso tsa linaheng tse ling JFE:NK-EH450/HARDOX450/DILLDUR:450V
