Waxaan macaamiisheenna u soo dirnay xaashi bir ah oo 321 ah oo aan daxal lahayn 1*1220*2440 oo ka timid UAE.

sifooyinka dabiiciga ah

Bir aan miridh lahayn oo 321 ah waa bir aan miridh lahayn oo austenitic ah oo titanium-ku xasiliyay (oo la mid ah 304 laakiin leh titanium lagu daray si looga hortago roobabka chromium carbide). Waxay bixisaa iska caabin heer sare ah oo heer sare ah iyo iska caabin daxalka oo isku dhafan.

Halabuurka Kiimikada ee Caadiga ah (%):

Walax Halabuurka

Chromium (Cr) 17.0 – 19.0

Nikkel (Ni) 9.0 – 12.0

Kaarboon (C) ≤0.08

Manganese (Mn) ≤2.0

Silikoon (Si) ≤1.0

Fosfooraska (P) ≤0.045

Sulfur (S) ≤0.03

Titanium (Ti) ≥5×C (ugu yaraan 0.4%)

Bir (Fe) Dheelitirnaan

Astaamaha Muhiimka ah

✔Xasillooni heer sare ah (ilaa 800-900)°C)

✔Waxay iska caabisaa roobabka carbide (dareen-celinta) inta lagu jiro alxanka

✔Iska caabin oksaydh iyo daxal wanaagsan (ka wanaagsan 304 deegaanno qaar)

Codsiyada

Iyada oo ay ugu wacan tahay iska caabbinta kulaylka iyo alxanka, birta aan miridhku lahayn ee 321 waxaa si ballaaran loogu isticmaalaa:

Qaybaha Matoorka Hawada Sare iyo Jet (nidaamyada qiiqa, qolalka gubashada)

Qalabka Kiimikada iyo Kiimikada Batroolku (beddelka kulaylka, weelasha cadaadiska)

Dhuumaha iyo Kuleyliyaha Heerkulka Sare (xasilloonida kulaylka)

Nidaamyada Qiiqa Gawaarida (noocyada kala duwan, kuwa wax ka beddela kicinta)

Qalabka Habaynta Cuntada iyo Daawooyinka (halka alxanka loo baahan yahay)

Qaybaha Daaweynta Kulaylka & Foornada (sababtoo ah iska caabbinta oksaydhka)
