ASTM A789 S31803 Embedded G Fin Tube With Aluminum Gr 1100 For Cooling Systems

ASTM A789 S31803 Embedded G Fin Tube With Aluminum Gr. 1100 For Cooling Systems

ASTM A 789 Specification for seamless and welded ferritic / austenitic stainless steel tubing for general service requiring general corrosion resistance, with particular emphasis on resistance to stress corrosion cracking.

Chemical Composition (%) max

Mechanical Properties

Duplex stainless steel possesses both austenitic and ferritic structures, and is resistant to chloride stress corrosion, pitting corrosion and crevice corrosion. It is suitable for handling media containing acids, alkalis and salts.Higher mechanical strength than ordinary austenitic stainless steel, capable of withstanding high-pressure environments.

The duplex stainless steel G fin tube is an ideal solution for efficient heat transfer and corrosion resistance in harsh environments. It performs particularly well in situations where traditional stainless steel or carbon steel cannot meet the requirements.The corrosion resistance, strength and weldability of duplex stainless steel are superior to those of 304/316L stainless steel.
