Product Description

ASTM AISI AUSTENITE 904LThickness 1.5 mm Stainless Steel Strip Coil For Car Pipe

 

1. Products Details

 

China GB BESN ASTM
00Cr20Ni25Mo4.5Cu 1.4539 904L

 

Features

 

Grade 904L stainless steel is a non-stabilized austenitic stainless steel with low carbon content. This high alloy stainless steel is added with copper to improve its resistance to strong reducing acids, such as sulphuric acid. The steel is also resistant to stress corrosion cracking and crevice corrosion. Grade 904L is non-magnetic, and offers excellent formability, toughness and weldability.

Fabrication

 

Grade 904L stainless steels are high purity steels with low sulphur content. They can be machined using any standard methods. These grades can be readily bent to a small radius under cold conditions. Although subsequent annealing is not required in most cases, it should be carried out when the fabrication is performed under severe stress corrosion cracking conditions.

 

Corrosion Resistance

 

Grade 904L stainless steels have excellent resistance to warm seawater and chloride attack. The high resistance of grade 904L against stress corrosion cracking is due to the presence of high amounts of nickel in its composition. Moreover, the addition of copper to these grades develops resistance to sulphuric acid and other reducing agents in both aggressive and mild conditions

The corrosion resistance of grade 904L is intermediate between super austenitic grades, with 6% molybdenum content, and standard 316L austenitic grades. Grade 904L is less resistant to nitric acid than grades 304L and 310L, which are free of molybdenum.

 

Application

 

Some of the major applications of grade 904L stainless steels include:

1. Wiring in electrostatic precipitators,Oil refinery components

2. Pulp and paper processing industries

3.Seawater cooling devices

4. Sulphuric acid processing plants
