What are the key properties of Stainless Steel 321/321H Buttweld Fittings?
Stainless Steel 321/321H Buttweld Fittings are commonly used in various industries due to their excellent corrosion resistance and high-temperature strength. Stainless Steel 321/321H Buttweld Fittings offer superior resistance to corrosion in a wide range of environments, including organic acids and moderately reducing to moderately oxidizing media. These fittings exhibit good mechanical properties at elevated temperatures, making them suitable for high-temperature applications. Stainless Steel 321H contains higher carbon content than 321, which provides improved resistance to sensitization and intergranular corrosion.
What is the manufacturing process for Stainless Steel 321/321H Buttweld Fittings?
Stainless Steel 321/321H Buttweld Fittings are typically manufactured through a process called hot forming or cold forming. In the hot forming process, the fittings are shaped by heating the stainless steel material to a suitable temperature and then using mechanical deformation techniques like bending, extrusion, or forging. Cold forming involves shaping the fittings at room temperature using processes such as cold drawing, cold rolling, or cold pressing.

Are Stainless Steel 321/321H Buttweld Fittings corrosion-resistant?
Stainless Steel 321 Buttweld Fittings exhibit excellent corrosion resistance. They are resistant to a wide range of corrosive environments, including organic acids, alkaline solutions, and oxidizing and reducing media. This corrosion resistance makes them suitable for various industries, including chemical processing, oil and gas, and pharmaceuticals.
What is the maximum temperature range for using Stainless Steel 321/321H Buttweld Fittings?
Stainless Steel 321H Buttweld Fittings have a maximum service temperature of approximately 870°C (1600°F). They can maintain their mechanical strength and oxidation resistance within this temperature range.
What are the recommended welding techniques for Stainless Steel 321/321H Buttweld Fittings?
Stainless Steel 321/321H Buttweld Fittings can be welded using several techniques, including gas tungsten arc welding (GTAW/TIG), gas metal arc welding (GMAW/MIG), and shielded metal arc welding (SMAW). It is essential to use filler materials specifically designed for stainless steel 321/321H to ensure proper weld integrity and corrosion resistance.
Can Stainless Steel 321/321H Buttweld Fittings be used in high-pressure applications?
Stainless Steel 321/321H Buttweld Fittings can be used in high-pressure applications. Their robust mechanical properties, including strength and hardness, combined with excellent corrosion resistance, make them suitable for demanding environments where high pressure is involved. However, it is important to consider the specific requirements and consult relevant industry standards to ensure the fittings are appropriate for the intended high-pressure application.
Cutting and Shaping
Once the raw materials are selected, they undergo a precise cutting and shaping process.
Heating and Forming
Heating the materials to a specific temperature ensures they become malleable, facilitating the shaping process.
Welding and Joining
These processes ensure secure and leak-proof connections, enhancing the reliability and longevity.
Finishing and Quality Control
After this the buttweld fittings undergo comprehensive finishing and quality control procedures.
Packaging and Delivery
To reach their destination in pristine condition, we employ careful packaging techniques.
