1. Introduction:
Industries operating in high-temperature environments—like aerospace, petrochemical, and thermal processing—frequently face the issue of material degradation due to oxidation and intergranular corrosion. Traditional stainless steel variants tend to lose their strength and integrity at elevated temperatures, leading to premature failures, safety hazards, and costly downtimes.
This problem calls for a material that can maintain mechanical properties and resist scaling at high temperatures. That's where Stainless Steel 321 Plates step in.
2. Product Introduction:
Stainless Steel 321 Plates are titanium-stabilized austenitic stainless steel sheets specifically designed to resist intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 427°C – 816°C (800°F – 1500°F). These plates are an enhanced version of 304 stainless steel, enriched with titanium to improve thermal stability and weldability.
They are manufactured in compliance with international standards such as ASTM A240 / ASME SA240, ensuring quality, durability, and performance.
3. Advantages of Stainless Steel 321 Plates
