E9310 Stainless Steel Aircraft Quality Bars
Type 9310 is a vacuum degassed, carburizing steel containing approximately 1.25% chromium, 3.25% nickel, and .12% molybdenum. This alloy is suitable for heavy sectioned components because of its high hardenability and fatigue resistance, and because of its high core strength and hardness offering a narrow hardness range between light and heavy sections. It offers excellent ductility and toughness, and may be used without carburizing. Most applications of 9310 do call for use in the carburized state, which increases its wear and abrasion resistance to a high degree. It passes the most rigid magnetic particle inspections.
Used principally in the carburized state where extreme core hardness is required in combination with a minimal hardness range.
