ASTM A376 TP304 Seamless Austenitic Stainless
Super austenitic stainless steel is a highly alloyed stainless steel whose composition is designed to provide higher corrosion resistance and mechanical properties than conventional austenitic stainless steel.
Products description:
High corrosion resistance: Especially excellent performance in inorganic and organic acids and their mixtures, but also excellent universal corrosion resistance.
Excellent structural stability: can maintain the stability and reliability of the material in a variety of harsh environments.
Improved mechanical properties: including high strength, high toughness, etc., so that it can show excellent performance in a variety of applications.
Excellent machinability: easy to manufacture and process into a variety of shapes and sizes.

Application field
Due to its excellent properties, super austenitic stainless steel is widely used in many fields:
Oil and gas industry: used in the manufacture of submarine pipelines, oil Wells and petroleum equipment to resist salt corrosion and seawater corrosion.
Chemical industry: Manufacture chemical reactors, storage tanks and pipes to cope with the corrosion of various chemicals.
Medical and bioengineering: Manufacturing artificial joints, surgical instruments and medical devices, etc., due to their good biocompatibility and corrosion resistance to biological fluids and medical environments.
Marine industry: Manufacture of ships and Marine equipment to resist the corrosion of seawater and the Marine environment.
In other fields, such as food processing, environmental protection equipment, pulp and paper industry, super austenitic stainless steel is also widely used to provide high corrosion resistance and durability of the material.
Manufacturing process
The manufacturing process of super austenitic stainless steel pipe usually includes the steps of billet preparation, tube billet heating, cross rolling perforation, periodic tube rolling, solution treatment, deep processing and finishing. These steps together ensure the quality and performance of the product.
