SUS321 isimbi ine tensile simba ≥ 520 uye ine mamiriro ezvinhu goho simba ≥ 205.

1. Hunhu Uye Kuwanda Kwekushandisa

Iko kuwedzerwa kweTi kunovandudza kuramba kweiyo intergranular ngura uye haina kukurudzirwa sechikamu chekushongedza.

2.Rorrosion Nemishonga

SUS321, SUS347, uye SUS348 isimbi dzesimbi dzisina kugadzikana dzino simbiswa ne titanium, niobium uye tantalum, uye inokodzera

shandisa senhengo dzakaunganidzwa patembiricha dzakakwirira. 348 isimbi isina simbi inokodzera indasitiri yemagetsi yenyukireya, ine chokwadi

zvinorambidzwa pamubatanidzwa wekufinha uye kuchera.

3. Chemical Kuumbwa

•  - Carbon C : ≤ 0.08

4. Mechanical Properties

• Nzvimbo shrinkage ψ (%): ≥ 50
• Kuoma: ≤187HB; ≤90HRB; ≤200HV

5. Heat Treatment Specifications Uye Metallographic Organization

Pisai kurapwa maratidziro:

• 1) mhinduro yakasimba 920 ~ 1150 ° C kukurumidza kutonhora;
• 2) zvinoenderana nezvinodiwa nechinodikanwa chinogona kudzikamiswa, kupisa kwekushisa kurapwa kuri 850 ~ 930 ° C,asi zvinofanirwa kudomwa muchibvumirano.

Batanidza kuchinyorwa ichi: Simbi Genus: SUS321

Dzokorora Chirevo: Kana pasina mirairo yakakosha, zvinyorwa zvese zviri pasaiti ino ndezvepakutanga. Ndokumbira uratidze kwakabva kudhindazve: https://www.cncmachiningptj.com/, thanks!
