316 stainless steel

316 stainless steel

316 is a member of the 18/8 chromium nickel family of austenitic stainless steels, with an addition of 2% molybdenum for improved corrosion resistance, particularly to localised corrosion in chloride containing environments. We can provide various sizes of 316 stainless steel tubes, plates, rolls, etc.

Introduction

Grade 316 Stainless Steel is the second most commonly used stainless steel, behind 304 stainless steel. It is an austenitic, corrosion-resistant steel with excellent strength, toughness, fabrication characteristics and weldability. The low carbon version, 316L, may be required for full corrosion resistance when thicker sections are welded. The 316H version has a guaranteed minimum carbon content, which ensures good strength at high temperatures.

The low carbon version, 316L, may be required for full corrosion resistance when sections thicker than about 5 mm are welded. The version with guaranteed high carbon, 316H, may be required for elevated temperature service, such as pressure vessels.
