Hordhac
Biraha birta ah waxaa loo yaqaanaa birta-daawaha sare.Waxay ka kooban yihiin 4-30% chromium.Waxa loo kala saaray biraha martensitic, austenitic, iyo biraha ferritic oo ku salaysan qaabdhismeedkooda crystalline.
Fasalka 317 birta aan dahsoon waa nooc wax laga beddelay oo ah 316 bir aan-qabin.Waxay leedahay awood sare iyo iska caabin daxalka.Xaashidan xogeed ee soo socota waxa ay ku siinaysaa tafaasiil dheeraad ah oo ku saabsan darajada 317 ee birta aan-qabin.
