Stellite 6 utawa kobalt 6 wesi adhedhasar kobaltdiprodhuksi dening casting centrifugal utawa wedhi ngecor, digunakake ing bushings lan nyandhang dering kanggo nambah resistance nyandhang.
kahanan:Casting, nyuda stres sadurunge diproses
Perawatan panas:relief kaku: panas casting kanggo minimal 800 ℃, tahan kanggo 1-4 jam cooling alon.
Proses: Kabeh casting saka kumpulan padha kudu kualitas padha tanpa pori, pori, hard panggonan, shrinkage cacat, retak utawa liyane defects mbebayani.Single castings karo bolongan isolasi ngisor 0,5 mm ora diijini kanggo ndandani, kepasang utawa gandheng.
Casting setengah rampung kanggo mesin final EMS bakal diwenehake ing "Status Inspeksi Mesin" kanggo ngidini casting dipriksa sadurunge dikirim.

Aplikasi:
Stellite6B alloy iku salah siji saka kobalt basis nyandhang tahan wesi Bai, nyandhang resistance lan kateguhan, bisa adaptasi kanggo paling kahanan, sawetara saka sudhut aplikasi, atose ing 37-45HRC; Iku utamané dipigunakaké kanggo kimia nyandhang-nolak piring, nyandhang- rod resisting, kursi tutup kimia uap, pangayoman agul-agul turbin uap, bushing anti-erosi, hot dip galvanis submerged roller lan bagean liyane; Dibandhingake karo WR6 (Stellite6) WR6B, WR6B wis luwih tahan nyandhang suhu dhuwur
