17-4PH 630 Pa uamea
Fa'amatalaga Puupuu:
Saky Steel's 17-4PH / 630 / 1.4542 o se tasi o uʻamea sili ona lauiloa ma sili ona masani ona faʻaogaina chromium-nickel uʻamea faʻapipiʻi faʻatasi ma mea faʻapipiʻi kopa, ua faʻamaʻaʻaina ma le martensitic structure. O loʻo faʻaalia i le maualuga o le corrosion resistance aʻo tumau pea le malosi o meatotino, e aofia ai le maaa. O le uamea e mafai ona galue i le vevela mai le -29 ℃ i le 343 ℃, aʻo faʻatumauina tulaga lelei. E le gata i lea, o mea o loʻo i totonu o lenei vasega o loʻo faʻaalia e ala i le lelei o le ductility ma o lo latou faʻafefeteina e faʻatusatusa i le 1.4301 / X5CrNi18-10.
17-4PH, e taʻua foi o le UNS S17400, o se uʻamea faʻamaʻaina martensitic. O se mea fa'apitoa ma fa'aaogaina lautele i pisinisi eseese, e pei o le aerospace, faaniukilia, petrochemical, ma le gaosiga o mea'ai.
17-4PH o loʻo i ai le malosi maualuga, lelei le faʻafefeteina, ma le malosi lelei pe a faʻatusatusa i isi uʻamea uʻamea. O se faʻafefiloi o le 17% chromium, 4% nickel, 4% copper, ma se vaega itiiti o le molybdenum ma le niobium. O le tuʻufaʻatasia o nei elemene e tuʻuina atu ai i le sila ona uiga faʻapitoa.
I le aotelega, 17-4PH o se mea sili ona lelei ma aoga e ofoina atu se paleni lelei o meatotino mo le tele o faʻaoga.
