ASTM A511 Stainless Steel Tube
ASTM A511 stainless steel tubes shall be made by a seamless process and by either cold working or hot working as specified. It is usually manufactured by hot-working steel and then cold finishing the hot-worked tubing to produce the desired shape, dimensions, and properties All austenitic tubes shall be furnished in the annealed condition.
Stainless steel alloys offer unrivaled performance across demanding industrial applications. However, not all stainless tubing provides equal quality, consistency, and corrosion resistance.
That’s why design and procurement engineers globally specify premium ASTM A511 seamless tubing for mission-critical components and assemblies. As an ISO-certified manufacturer of top-tier stainless pipes and tubes, XYZ Company delivers ASTM A511 products that meet even the strictest standards of excellence.

What is ASTM A511 Stainless Steel Tubing?
ASTM A511 defines materials, properties, manufacturing methods, and testing procedures for seamless austenitic stainless tubing used in severe-service applications. This standard covers straight lengths of round, rectangular, and square tubing in sizes up to 12 inches (305mm) and wall thicknesses up to 2 inches (51mm).
ASTM A511 tubes feature austenitic stainless grades including 304, 304L, 316, 316L—premium steel alloys optimized for strength, weldability and elevated temperature and pressure performance. These tubes suit extensive fabrication while resisting corrosion in harsh conditions.

A511 is a standard specification for seamless stainless steel mechanical tubing. It covers various grades of stainless steel tubes that are suitable for mechanical applications, such as bearings, cylinders, and other components requiring high strength and corrosion resistance. The standard specifies the dimensions, tolerances, and mechanical properties of the tubes. It is commonly used in industries such as automotive, aerospace, and machinery.
