ASTM A511 MT316L stainless steel Seamless Pipe

ASTM A511 standard covers seamless (welded seamless) tubing for mechanical applications requiring strength and durability. The MT316L designation indicates a specific stainless steel composition that provides improved performance under corrosive conditions.

GNEE's ASTM A511 MT316L seamless tubing is a cold-finished mechanical tubing made from a specific grade of stainless steel (316L) and cold-rolled. It is designed for high-corrosion-resistance applications. Typical applications include heat exchangers, condenser tubing, instrumentation, automotive parts, food processing equipment, pharmaceutical machinery, and marine components.
