Nhanganyaya yeSimbi Isina Kusimba ye17-4ph

17-4 simbi isina ngura (630) isimbi isina ngura inoomesa chromium-copper precipitation inoshandiswa pakushandisa inoda simba rakawanda uye inodzivirira ngura zvine mwero. Simba rayo guru ndiro
yakachengetwa kusvika panosvika madhigirii Fahrenheit mazana matanhatu (316 degrees)

Kuramba Kuora

Alloy 17-4 PH inokwanisa kukurira kurwiswa nengura zviri nani kupfuura chero simbi dzisingatsvimbi dzakajairwa uye yakafanana neAlloy 304 mune zvakawanda zvemidziyo.

Kana paine njodzi dzinogona kukonzera kuputika kwengura, tembiricha dzinonyanya kuchembera dzinofanira kusarudzwa pamusoro pe550°C (1022°F), zviri nani 590°C (1094°F). 1022°F (550°C) ndiyo tembiricha yepamusoro yekupisa chloride media.

1094°F (590°C) ndiyo tembiricha yepamusoro yekudziya muH2S media.

Chiumbwa ichi chinogona kutsemuka kana kukanganiswa kana chikaiswa mumvura yegungwa isingamire kwenguva yakareba.

Haina ngura mune mamwe maindasitiri emakemikari, peturu, mapepa, mukaka uye kugadzira chikafu (zvakaenzana ne304L grade).
