Product Description

ALLOY 20 N08020 ALLOY 28 N08028 ALLOY 31 33 58 59 STAINLESS STEEL PIPE

Introduction

INCOLOY alloys are composed of nickel-chromium-iron as the primary elements. Additives that are used in this alloy to enhance its strength, corrosion resistance include molybdenum, copper and nitrogen. These alloys are classified as super alloys due to their high strength and ability to function at high temperatures.

INCOLOY alloy belongs to the austenitic stainless steel group and is resistant to a variety of corrosive environments. The combination of chromium and molybdenum make this alloy resistant to both oxidizing and reducing acids and salts. The copper content makes it resistant to sulfuric acid.
