416R

416R (Barrel Quality) Stainless Bar

416R stainless bar is a low sulfur, pre-hardened variant of 416 stainless suitable for manufacturing high quality precision rifle and pistol barrels. With a 12% chromium content 416R provides improved general corrosion resistance over alloy steels commonly used or barrel applications.

Machinability

• An optimized sulfur content ensures excellent machinability while avoiding inclusions detrimental to performance in the field.
• All material is stocked in the hardened and stress relieved condition.
• Stress relief as the final step minimizes residual stresses in the bar and improves dimensional stability during gun drilling and reaming.

Quality & Consistency

• 100% Eddy Current inspected to detect surface defects.
• 100% Ultrasonically inspected to ensure internal soundness.
• Hardness range controlled to Rockwell C 26-32.
• DFARs compliant, with 100% USA melt and manufactured Bar also available.
• Controlled lengths of 144 inches +2”, -0”.
