R H Alloys is the largest Stainless Steel 321 Sheet Supplier in India. Stainless Steel 321 sheet is a high-performance, heat-resistant material primarily known for its excellent resistance to oxidation and corrosion, particularly in high-temperature environments. This grade is alloyed with titanium, which stabilizes the material and helps prevent carbide precipitation in welding and high-temperature applications. It’s a popular choice for use in aerospace, chemical processing, and power generation industries, as well as in high-temperature exhaust systems and heat exchangers. Stainless Steel 321 offers superior weldability compared to other stainless steel grades, making it a versatile option for complex, large-scale projects.

The presence of titanium in Stainless Steel 321 also enhances its ability to resist scaling and pitting corrosion, especially in acidic and chloride-rich environments. It retains its strength and durability even when exposed to temperatures up to 900°F (482°C), which is a key reason it’s often used in environments subject to elevated heat or thermal cycling. While 321 stainless steel is similar to 304, its higher resistance to heat and corrosion makes it a preferred material for applications where temperatures can fluctuate, ensuring longevity and reliability.
