9310Vac Melt

פלדה זו היא סגסוגת הניתנת לפחמון המיוצרת על ידי אלקטרודת ואקום. יש לה כושר חיסום גבוה, קשיות גבוהה בליבה ועמידות בפני התעייפות, דבר ההופך אותה לאידיאלית לשימוש בהילוכים למנועים של מטוסים.

Alloy Steels -> 9130 vac melt

General Characteristics

9310 VAC-ARC is a premium quality alloy carburizing steel produced by the vacuum consumable electrode process. It has a high hardenability, high core hardness and high fatigue strength, all of which make it ideally suited for critical aircraft engine gears.
