Stainless Steel 904L Long Weld Neck Flange Manufacturers in India – Sachiya Steel International Private Limited

For high-performance stainless steel products, Sachiya Steel International Private Limited is a leading Stainless Steel 904L Long Weld Neck Flange manufacturer in India. We specialize in durable and reliable flanges that cater to the needs of industries such as chemical processing, oil and gas, and pharmaceuticals. These flanges are built to withstand extreme environments while offering excellent corrosion resistance and strength.

Why Choose Stainless Steel 904L for Long Weld Neck Flanges?

Stainless Steel 904L is a low-carbon, high-alloy austenitic stainless steel known for its exceptional resistance to corrosion, particularly in harsh, acidic environments. Its high chromium and nickel content, along with the addition of copper, enhances resistance to reducing acids like sulfuric acid. Additionally, 904L Long Weld Neck Flanges are designed for high-stress applications. They ensure strong weld joints and withstand pressure effectively.

The long weld neck design reinforces the weld point, making it suitable for high-temperature and high-pressure systems. Moreover, the 904L stainless steel ensures superior corrosion resistance in aggressive chemical environments, making it ideal for industries working with corrosive substances, chemicals, or seawater.

Key Features of Stainless Steel 904L Long Weld Neck Flanges

• Corrosion Resistance: Highly resistant to acidic and chloride-containing environments.
• High Strength: Perfect for high-stress and high-pressure applications.
• Temperature Resistance: Suitable for both high and low-temperature conditions.
• Durability: Long weld neck design reduces stress at the joint, enhancing longevity.
• Low Carbon Content: Reduces the risk of intergranular corrosion after welding.
