316 stainless steel round bar

316 stainless steel round bar is an austenitic chromium-nickel steel that contains molybdenum, providing superior corrosion resistance and increased strength at elevated temperatures compared to 304 stainless steel. Commonly known as food-grade or marine-grade stainless steel, 316 stainless steel round bar is particularly suited for resisting a wide range of chemical and acidic corrodents, making it ideal for marine applications.

Typical uses of 316 stainless steel round bar include food production, pharmaceutical equipment, furnace parts, heat exchangers, valves and pumps, chemical equipment, and various marine applications. It is often offered in a lower carbon dual grade, 316/316L, enhancing machinability and corrosion resistance when welded.

Properties and Applications

316 stainless steel round bar is moderate to weld, cut, form, and machine with the appropriate equipment. Metals Depot stocks a wide range of 316 stainless steel round bars available for online purchase in ready-to-ship precut or mill lengths. Customers can also order custom cuts in small or large quantities.

This material is versatile, with applications in natural gas, petroleum, aerospace, food and beverage, industrial, cryogenic, architectural, and marine fields. 316 stainless steel round bar boasts high strength and excellent corrosion resistance, making it suitable for even the most corrosive marine environments. While it is stronger than 304 stainless steel, it is less malleable and machinable. It maintains its properties in both cryogenic and high-temperature conditions.

316L stainless steel round bar features very low carbon content, minimizing carbide precipitation during welding, which enhances its suitability for moisture-rich environments, such as in marine applications and paper processing equipment.
