What is Stainless Steel 321/321H Bars and Wires?
Stainless Steel 321 Bars and Wires are a type of austenitic stainless steel alloy that contains titanium. The addition of titanium provides stabilization against chromium carbide precipitation, which can lead to intergranular corrosion. These bars and wires are available in various sizes and shapes, such as round bars, hex bars, square bars, and wire coils. They are known for their excellent corrosion resistance, high-temperature strength, and weldability.

Stainless Steel 321H Bars and Wires are a high-carbon version of Stainless Steel 321 Bars and Wires. The "H" in 321H is "high carbon," indicating a higher carbon content than standard Stainless Steel 321. This increased carbon content provides the material with improved high-temperature strength and hardness, making it suitable for high-temperature applications. Adding titanium to Stainless Steel 321H makes it resistant to sensitization and intergranular corrosion.

What are the key properties and characteristics of Stainless Steel 321/321H bars and wires?
Stainless Steel 321/321H Bars and Wires are known for their excellent corrosion resistance, high-temperature strength, and weldability. They also exhibit exceptional resistance to intergranular corrosion and oxidation in challenging environments. Other notable properties and characteristics include their low thermal conductivity, high mechanical strength, and long-lasting durability. Additionally, they can be easily fabricated and machined, making them suitable for various applications in various industries.
What are the common applications and industries where Stainless Steel 321/321H bars and wires are utilized?
Stainless Steel 321/321H bars and wires are commonly used in several industries, including aerospace, chemical processing, oil and gas, power generation, and pharmaceuticals. They are utilized in various applications such as heat exchangers, furnace parts, expansion bellows, aircraft exhaust stacks, manifolds, and chemical processing equipment. Additionally, they manufacture high-temperature sensors, boiler baffles, and firewalls due to their excellent thermal stability and mechanical strength.
How does the composition of Stainless Steel 321/321H bars and wires differ from other stainless steel alloys?
The primary difference between Stainless Steel 321/321H bars and wires and other stainless steel alloys is the addition of titanium. The titanium content in Stainless Steel 321/321H helps prevent chromium carbide precipitates from forming during high-temperature exposure, which can lead to intergranular corrosion. That makes it more resistant to sensitization and intergranular corrosion than other stainless steel grades. Additionally, Stainless Steel 321/321H has a higher carbon content than 304 or 316 stainless steel, which increases its strength and hardness.
