Anti - Corrosion 174PH/SUS630/F51/2205 Stainless Steel Coils: Ideal for Chemical Tank Lining

Product Overview

Our anti - corrosion 174PH/SUS630/F51/2205 stainless steel coils are a top - notch solution for chemical tank lining. These coils are manufactured with the highest precision and quality standards, ensuring long - lasting performance in harsh chemical environments. With a surface treatment of polished finish, they not only offer excellent corrosion resistance but also a smooth and aesthetically pleasing appearance.

Material and Standard

Material Composition

• 174PH/SUS630: This grade of stainless steel contains a balanced composition of chromium, nickel, copper, and other elements. Chromium provides a passive oxide layer on the surface, which is crucial for corrosion resistance. Nickel enhances the toughness and ductility of the steel, while copper contributes to its precipitation - hardening properties, allowing for high strength.
• F51/2205: F51/2205 is a duplex stainless steel. It combines the advantages of austenitic and ferritic stainless steels. The austenitic phase provides good toughness and weldability, while the ferritic phase offers high strength and resistance to stress - corrosion cracking.

Standard Compliance

These stainless steel coils adhere to the ASTM standard. ASTM standards are globally recognized for their strict requirements in terms of material properties, dimensions, and testing methods. By meeting ASTM standards, our coils ensure compatibility with international industry norms and can be used in various applications around the world.

Manufacturing Technique

The coils are produced using the hot - rolled technique. Hot rolling involves heating the steel above its recrystallization temperature and then passing it through rollers to achieve the desired thickness and shape. This process has several advantages:

• Improved Grain Structure: Hot rolling refines the grain structure of the steel, enhancing its mechanical properties such as strength and ductility.
• Cost - Effective: It is a relatively cost - effective manufacturing method, which allows us to offer high - quality products at a competitive price.
• Large - Scale Production: Hot rolling enables large - scale production of stainless steel coils, ensuring a stable supply for our customers.

Anti - Corrosion Performance

Resistance to Chemicals

Our stainless steel coils are highly resistant to a wide range of chemicals commonly found in chemical tanks, such as acids, alkalis, and salts. For example, in sulfuric acid environments, the passive oxide layer on the surface of the steel prevents the acid from reacting with the metal, thus protecting the tank lining from corrosion. In alkaline solutions, the steel maintains its integrity and does not undergo significant degradation.

Resistance to Stress - Corrosion Cracking

Stress - corrosion cracking is a major concern in chemical tank applications. The F51/2205 duplex stainless steel in our coils has excellent resistance to stress - corrosion cracking. Its unique duplex microstructure can effectively prevent the propagation of cracks under the combined action of tensile stress and a corrosive environment.

Application in Chemical Tank Lining

Durability

When used as a lining for chemical tanks, our stainless steel coils significantly extend the service life of the tanks. The anti - corrosion properties prevent the tanks from being damaged by the chemicals they store, reducing the need for frequent repairs and replacements.

Compatibility

The coils are compatible with various types of chemical tank materials and construction methods. They can be easily welded or bonded to the tank structure, ensuring a tight and secure lining. This compatibility also allows for seamless integration into existing tank systems during retrofitting projects.
