ASTM B709/W. Nr. 1.4563/Alloy 28 Nickel Alloy Tube for Heat Exchanger Superalloy Incoloy 28 Alloy Pipe

Introduction

Alloy 28 (UNS N08028, W. Nr. 1.4563, Sanicro 28) is a nickel-iron-chromium alloy with additions of molybdenum and copper. It has excellent resistance to both reducing and oxidizing acids, to stress-corrosion cracking, and to localise attack such as pitting and crevice corrosion. The alloy is especially resistant to sulphuric and phosphoric acid. Used for chemical processing, pollution control equipment, oil and gas well piping, nuclear fuel reprocessing, acid production and pickling equipment.

Application

▪ Chemical and petrochemical processing industry
▪ Downhole service in deep sour gas wells.
