What Qualities Are Present in Hastelloy Screws?

Superior Corrosion Resistance: While other materials corrode quickly, these fasteners withstand attacks from sulfuric acid, hydrochloric acid, and chloride conditions. High-Temperature Performance: Because they can tolerate temperatures of up to 1,093°C without losing their mechanical properties or corrosion resistance, they are perfect for thermal processing applications.​​​​​​​​​​​​​​ Superior Mechanical Strength: Even under the most trying conditions, dependable fastening is guaranteed by exceptional tensile and yield strength.

Application

Chemical Processing Industry: Heat exchangers, pipeline systems, and reactor vessels that handle corrosive substances.

Petrochemical Sector: Refinery equipment, catalyst systems, and hydroprocessing units.

Aerospace Applications: Engine components, exhaust systems, and structural fasteners for high-temperature environments.

Marine Industry: Seawater handling apparatus, desalination systems, and offshore platforms.

Pharmaceutical Manufacturing: Sterile processing systems, reactor vessels, and clean room apparatus.

Production And Processing Technology

Consistent quality and performance are guaranteed by our sophisticated production process. To get the best mechanical qualities, we use controlled heat treatment after precise cold heading technology.

The production process includes automated thread rolling, customized heat treatment cycles, and precision machining. The necessary microstructure is achieved for every batch by solution annealing at 1,177°C and then rapidly quenching with water.

Sophisticated quality control systems monitor dimensional correctness, surface finish, and mechanical properties during production. This guarantees that each fastener satisfies your precise requirements.

What Is The Production Process Of Hastelloy Screws？

• Raw Material Inspection: Dimensional confirmation and a chemical composition analysis are performed on incoming alloy bars.
• Cutting and Preparation: Using cutting-edge machinery, we precisely cut to the necessary lengths.
• Cold Heading: The head geometry is produced by high-pressure forming while preserving the integrity of the material.
• Thread Rolling: Accurate pitch and excellent surface polish are guaranteed by precise thread rolling.
• Heat Treatment: To maximize corrosion resistance, solution annealing is followed by regulated cooling.
• Machining: Using CNC equipment to do secondary processes for unique characteristics.
• Surface finishing includes passivation, cleaning, and final finishing in accordance with client requirements.
• Packaging: Safe packaging to guard against harm while being transported and stored.

Inspection Of Quality

Every product meets strict criteria thanks to our extensive quality system. Sample products from each production batch are tested for tensile strength, hardness, and corrosion resistance. In dimensional inspection, precise measuring instruments are utilized to verify thread precision, head geometry, and overall dimensions. Surface finish testing ensures consistent look and function. Analysis of the alloy's chemical composition verifies that its content satisfies specifications. Tensile strength, yield strength, and elongation qualities are all verified by mechanical testing.
