What are Stainless Steel 321/321H Flanges?

The major distinction with 321 and 321H is in the level of carbon—321H having greater carbon to provide improved high-temperature strength. The flanges are extremely well suited to service in repeated thermal cycling, pressure, and stress applications. Having excellent mechanical properties and high metallurgical properties, Stainless Steel 321/321H Flanges are perfectly suited to piping systems calling for oxidation and corrosion resistance, especially in the petrochemical and refinery and aerospace industries.

Meta Aerospace boasts itself to be among the highest rated Stainless Steel 321/321H Flanges Manufacturers with an extensive line of flange products including weld neck flanges, slip-on flanges, socket weld flanges, blind flanges, and threaded flanges. All products are designed through advanced technology and rigorous quality checks to provide maximum structure and long service life under extreme conditions.

They are known to exhibit superior forming and weld characteristics. Another highlight of Stainless Steel 321/321H Flanges is high creep strength and resistance to scaling up to 870°C (1600°F). Their stabilized condition prevents sensitization, and thus they are perfectly suited for heat-affected zone welding and repeated exposure to high temperatures. They possess better cryogenic temperature toughness and sound ductility and surpass several other stainless grades in vital uses.

Meta Aerospace is one of the prominent Stainless Steel 321/321H Flanges Suppliers dedicated to quality, prompt delivery, and affordable price. Our products adhere to international standards like ASTM A182, ASME SA182, and DIN specifications and cater to diversified industrial needs of customers spread globally. The flanges are supplied in pressure classes like 150#, 300#, 600#, and 900#, suited to meet both ANSI and custom designing specifications.

Uses and Applications Stainless Steel 321/321H Flanges?

The flanges are suitable for operations demanding longevity, leakage-proof joints, and resistance to corrosive media. They are reliable and maintain structure under highly acidic or basic conditions too.

• In the oil and gas sector, these flanges are used in high pressure piping and offshore rigs.
• In the petrochemical and chemical sector, these flanges are appreciated for withstanding corrosive chemicals and solvents.
• In the power generation sector, the flanges are used in steam turbines and heat exchangers owing to temperature withstanding capabilities.
• In the pharmaceutical and food processing sector, the hygienic qualities are important in SS 304/304L flanges.
• In marine application too, these flanges are an important part of the system with superior performance in saltwater environments.
• In the automotive and aerospace markets, these are used in engine parts and exhaust systems where strength and corrosion resistance are paramount.
