NM400/NM 450 tahan aus pelat baja
NM450 minangka piring nyandhang kekuatan dhuwur.
Jeneng: N kanggo resistensi (nai), M minangka huruf pinyin pisanan saka rong karakter Cina kanggo grinding (mo),
lan 450 nggantosi atose Brinell rata-rata piring baja iki
Perawatan panas: tempering suhu dhuwur, quenching + tempering (quenching lan tempering)
Aplikasi: NM450 nyandhang-tahan piring baja digunakake digunakake ing mesin pertambangan, mesin pertambangan batu bara,
mesin pangayoman lingkungan, mesin construction, etc., lan uga umum digunakake minangka dhuwur-kekuatan
baja struktural kanthi kekuatan ngasilake ≥850MPa.
Fungsi: Iku utamané kanggo nyedhiyani pangayoman ing kesempatan utawa bagean sing perlu nyandhang resistance, supaya urip
peralatan maneh, downtime pangopènan disebabake pangopènan suda, lan investasi ibukutha
salaras suda.
Kinerja: Ngasilake luwih saka 950, lan kekuatan tarik yaiku 1180.
NM450 cocog karo standar lan kelas asing JFE:NK-EH450/HARDOX450/DILLDUR:450V
