9310H carburizing steel
9310H carburizing steel
(OP)
Can someone explain the intention behing this steel's chemistry and it's preferred applications? Is it widely used? I am trying to expand my horizon on carburizing grades. I believe I have a firm grasp of 8620H/4120H steels and their intent, but know little about 9310H.
-Thanks-

The AISI Type 9310H contains;
0.07-.13%C
0.4-0.7% Mn
1.0-1.45% Cr
2.95-3.55% Ni
0.08-.15% mo
The nickel content in this steel is the key alloying element that promotes both case and core toughness during carburizing. Nickel reduces the martensite start temperature and combined with chromium enhances hardenability. Timken and other alloy steel manufacturers recommend carburized 9310H for high performance applications because of enhanced toughness and high fatigue strength.

In my experience this is the best gear material you can get unless you go to a tool steel grade or maraging steel. The high Nickel content is also the key to touhgness and fatigue strength mentioned above.

Macsteel is another producer that you should investigate. For fatigue data of carburized gears, I would recommend reviewing the following keyword search at Scirus:

The following link has several conference papers on fatigue of carburized gears published over the past 20 years at the ICSP:
