Corrosion-resistant alloy forgings GBn 276-88
Introduction
Corrosion resistant alloys are a special family of metal alloys, consisting of metals that are highly resistant to corrosion. Corrosion is a destruction process of an object, caused by a chemical reaction between the metal and its surrounding environment. This can be accelerated by o......
