Main characteristics and uses of precipitation hardening stainless steel S51778 0Cr17Ni7Al

Introduction

0Cr17Ni7Al alloy is an austenite non-magnetic precipitation hardening (PH) stainless steel. This alloy has good corrosion resistance, wear resistance and processability, and is often used in industry, such as aerospace, petrochemical and marine engineering.

Chemical Composition

0Cr17Ni7Al is composed of 0.03-0.15% carbon, 18.0-20.0% chromium, 7.0-10.0% nickel, 1.5-2.5% molybdenum, 2.5-3.5% aluminum and 0.5-1.5% manganese by weight.

Main Features

This alloy exhibits precipitation hardening characteristics. When solution treated it is non-magnetic, but following solution treatment, high temperatures can be used to induce precipitation hardening that increases yield strength, tensile strength and hardness. Therefore, high temperature processes should be avoided when annealing this alloy as it can destroy the PH characteristics and magnetic properties.

This alloys displays good corrosion resistance to both oxidizing and non-oxidizing acids, including nitric, sulfuric, hydrochloric and phosphoric acids. The corrosion resistance is further enhanced by the addition of molybdenum and aluminum.

This alloy has good resistance to chloride attack and demonstrates excellent mechanical properties in both hot and cold-worked conditions.

Applications

0Cr17Ni7Al is a versatile alloy and is applied in a number of industries. It finds use in chemical and food processing plant, architecture, and construction as well as in furniture and kitchen equipment. It is often used for components that require good wear resistance and corrosion resistance.
