316 / 316L

Overview and Applications

316 / 316L Stainless Steel Equal Angle is a corrosion-resistant austenitic structural profile featuring two equal legs forming a precise 90-degree angle. Designed for framing, reinforcement, and load-bearing structural applications, its symmetrical geometry ensures balanced stress distribution and enhanced structural stability. Manufactured in accordance with ASTM A276 and related specifications, 316 stainless steel equal angle provides superior corrosion resistance, particularly in marine and chloride-exposed environments. The low-carbon 316L grade enhances weldability and reduces the risk of carbide precipitation, making it ideal for welded structural assemblies in aggressive service conditions.

Performance & Material Advantages

316 / 316L stainless steel equal angle offers enhanced resistance to pitting, crevice corrosion, and chemical exposure due to its molybdenum content (approximately 2–3%). With a composition of approximately 16–18% chromium, 10–14% nickel, and added molybdenum, this alloy provides superior performance in marine, coastal, and chemically aggressive environments. Its equal leg configuration improves structural reinforcement capability and load-bearing efficiency. With excellent weldability, formability, and dimensional stability, 316 stainless steel angle is suitable for structural supports, marine hardware, processing equipment frameworks, and heavy-duty industrial fabrication.

Technical Specifications

316 / 316L stainless steel equal angle is produced in compliance with ASTM A276 standards, ensuring controlled chemical composition and consistent mechanical properties. This molybdenum-bearing austenitic stainless steel provides enhanced corrosion resistance compared to 304 grades. Available in various leg sizes, thicknesses, and standard lengths, 316 stainless steel equal angle is typically supplied in hot-rolled condition for structural and fabrication applications requiring improved environmental resistance.
