Product Introduction

Products Description

1.4462 duplex stainless steel is a cost effective solution for many applications where the 300 series stainless steels are susceptible to chloride stress corrosion cracking. Stress corrosion cracking occurs when stainless steels are subjected to tensile stress, while in contact with solutions containing chlorides. Increasing temperatures also increase the susceptibility of stainless steels to stress corrosion cracking.

The combination of chromium, molybdenum and nitrogen convey the good resistance of 2205 to chloride pitting and crevice corrosion. This resistance is extremely important for services such as marine environments, brackish water, bleaching operations, closed loop water systems and some food processing applications. The high chromium, molybdenum and nitrogen contents of 1.4462 provide corrosion resistance superior to common stainless steels, such as, 316L and 317L in most environments.

What are the characteristics of Duplex 1.4462?

High resistance to chloride stress corrosion cracking
Resistance to chloride pitting and crevice corrosion
Good general corrosion resistance
Good sulfide stress corrosion resistance
High Strength
Good weldability and workability

In what applications is Duplex 1.4462 used?

Chemical process vessels, piping and heat exchangers
Pulp mill digesters, bleach washers, chip pre-steaming vessels
Food processing equipment
Oil field piping and heat exchangers
Flue gas desulfurization equipment
