Whether you are in the oil and gas industry, petrochemical sector, or dealing with other demanding environments, our flanges are built to last. Stainless Steel 321 offers unique properties like enhanced corrosion resistance and excellent stability, even in extreme conditions. This makes it the perfect choice for industries that require long-lasting, reliable components.

Why Stainless Steel 321?

Stainless Steel 321 is a titanium-stabilized grade, known for its resistance to intergranular corrosion, especially at elevated temperatures. This makes it a go-to material for applications requiring stability and longevity in environments that experience temperatures up to 870°C. The addition of titanium helps in preventing carbide precipitation, which can weaken the material over time.

At Sachiya Steel International, we focus on delivering flanges that are not only strong but also corrosion-resistant, making them ideal for long-term use in industries that deal with aggressive chemicals, high pressures, and high temperatures.
