9310 VAR / AMS 6265 Round Bar: Material Profile
9310 is a nickel-chromium-molybdenum carburizing steel used for components that need a wear-resistant surface and a tough core. Gear manufacturers use this alloy family for demanding transmission and aerospace applications.
AMS 6265 covers premium aircraft-quality 9310 with vacuum consumable-electrode remelting. It is a specific material requirement, separate from a general 9310 grade designation.
Ohio Bar & Metal reviews round-bar inquiries by specification, incoming condition, diameter and production quantity. Include approved-source restrictions and the delivery schedule with the material callout.

Ordering 9310 VAR for Production
Melt route and specification
State AMS 6265 and the required revision. If the drawing also specifies a mill, customer standard or a different melting route, include that exact requirement.
Stock before carburizing
Give the incoming bar condition and dimensional allowance. Identify any customer requirements for cleanliness, hardenability or inspection without substituting finished-gear properties for bar acceptance criteria.
Run size and releases
List pounds or pieces with units, cut lengths, the first production release and annual demand if known. Specify whether heat-lot continuity is required across releases.
AMS 6265: Purchasing Questions
Is AMS 6265 the same as ordinary 9310?
9310 identifies the alloy family. AMS 6265 adds a specific premium aircraft-quality requirement and remelting route. Material must be quoted and certified to the complete purchase callout.
Should I include carburizing requirements with the inquiry?
Include the requirements that apply to the material being purchased. If carburizing occurs after machining, distinguish those finished-part requirements from the required condition of the incoming bar.
Can the inquiry cover truckload or scheduled quantities?
Yes. Send the total requirement and individual release sizes. Available dimensions, source approval, processing and schedule are confirmed during quote review.
