Product Description

Product Description

 

Introduction

J92205 is a duplex stainless steel. It features excellent seawater corrosion resistance and has nearly twice the strength of common stainless steels. This alloy also goes by the name CD3MN. As an alloy it is one of the more commonly used duplex stainless steels.
 

Duplex 4A is a duplex stainless steel containing elements like cobalt, chromium, and nickel. It combines features of both austenitic and ferritic stainless steels, offering higher strength and corrosion resistance, particularly in chloride-containing environments.
