718 limuuamea 718 palasitika uʻamea uamea gaosia e Suetena ASSAB o loʻo i ai mea faʻainisinia, machinability, ma tekinolosi faʻagaioiga faigofie, o lea e faʻaaogaina lautele i le gaosiga o gaosiga ma gaosiga o gaosiga.E le gata i lea, o le 718 die steel na muamua faʻamaʻaina i le maaa o 41 ~ 47HRC ina ua uma ona tuʻua le fale gaosi oloa e ala i se gaosiga faʻapitoa, lea e mafai ona faʻaitiitia ai fesoʻotaʻiga togafitiga vevela i nisi o galuega faatino ma faʻaleleia manuia tau tamaoaiga.

Henglei 718 mate uamea, 3Cr2NiMo o lo tatou atunuu o se tulaga uamea faaleleia mai le P20 (3Cr2Mo), ma o lona tulaga lelei ua matua faaleleia e faatumuina ai le faaletonu o le P20 mate uamea ma fetaui ma taimi e le mafai e le P20 mate uamea ona ausia manaoga.I le faaopoopo atu i togi uamea masani a Saina ua taʻua i luga, o togi uʻamea o loʻo faʻaalia nei i le maketi uamea i loʻu atunuu o le P20 + Ni.Suetena 718, 718H (ASSAB), PX5\PX4 (Iapani Datong Special Steel), GS-711, GS-738, GS-312, GS-318 (Siamani Thyssen), Austria's M238 ECOPLUS (Bai Lu Company), CS718 (Saina) Great Wall Special Steel), SWP20 (Shanghai Nu. 5 Steel Company), ma isi, e le gata i le le faʻaaogaina mo vaega palasitika palasitika ma manaʻoga faʻafefete, o le taimi nei o se uʻamea masani masani mo le faʻaaogaina lautele o le faʻaogaina o palasitika. uamea.E masani ona taʻua o le "uila palasitika", ma o le fou faatoa atiina ae togi uʻamea e masani ona faʻaaogaina o se faʻatusatusaga masani.

Falegaosimea: ASSAB 718 HB: 290-310

Tulaga tu'uina atu: O lo'o tu'uina atu le sila i se tulaga fa'afefeteina.A maeʻa le maliliega, e mafai foi ona faia le tuʻuina atu e aunoa ma le faʻafefe.

718 u'amea o se Swedish ASSAB fa'ata muamua fa'amaa'a acid-fa'amaonia palasitika li'a uamea.O le uʻamea e muaʻi faʻamaʻaina, faʻatasi ai ma mea toniga, maualuga le mama, faʻalelei faʻalelei ma faʻataʻitaʻiga o ata.E iai fo'i le malosi maualuga, lelei le fa'atinoina o le eletise ma le fa'atinoina o le dermatoglyph.E mafai foʻi ona faʻaaogaina le uamea muamua i totonu o le paʻu e aunoa ma le tineia, ma o le flange e mafai ona faʻamaʻaina afi e faʻateleina ai le maaa i le 52HRC.

O le uamea e lelei machinability ma ofuina tete'e, ma toniga maaa tufatufaina.E iai fo'i le lelei o le fa'alelei, fa'atekonolosi fa'agaioiga faigofie ma le tau fa'atatau, o lea la e telē le fua.
