What is 321H/321 stainless steel sheet?
321H/321 stainless steel sheet is a type of austenitic stainless steel that contains titanium as a stabilizing element. It has excellent resistance to intergranular corrosion and can withstand high temperatures up to 800-1500°F. 321H stainless steel has a higher carbon content than 321 stainless steel, making it more suitable for high-temperature applications requiring greater strength and creep resistance. Due to their excellent resistance to oxidation, high strength, and low maintenance requirements, these sheets are widely used in various industries, such as chemical processing, oil and gas, and aerospace.
What are the features of 321H/321 stainless steel sheets?
The 321H/321 SS Sheet features include corrosion resistance, high-temperature resistance, strength, versatility, and low maintenance requirements. They are highly resistant to intergranular corrosion, stress corrosion cracking, and pitting. Adding titanium and carbon gives these sheets superior strength and resistance to creep, making them ideal for high-temperature applications. They are also highly formable, weldable, and machinable, making them suitable for various industrial applications.
What are the advantages of 321H/321 stainless steel sheets?
The advantages of the 321H/321 SS Sheet include excellent resistance to intergranular corrosion, stress corrosion cracking, and pitting, high-temperature resistance, superior strength and resistance to creep, versatility, and low maintenance requirements.
What are the applications of 321H/321 stainless steel sheets?
321H/321 stainless steel sheet is widely used in various applications, including chemical processing, oil and gas, aerospace, and marine environments. They are suitable for high-temperature applications and components exposed to corrosive environments. These sheets are used for pressure vessels, heat exchangers, expansion bellows, and exhaust systems. They are used in the manufacturing of food and pharmaceutical industries and in structural components for the construction industry.
