As a leading Stainless Steel 904L Pipe Manufacturer, we focus on producing stainless steel pipes that exceed global standards and meet the expectations of clients across industries.

Our SS 904L pipes are manufactured with precision using high-quality raw materials and cutting-edge technology. Each product is carefully tested to ensure consistent performance, making them suitable for industries such as oil and gas, chemical processing, marine engineering, and power generation.

What Makes SS 904L Stainless Steel Special?

Stainless Steel 904L (UNS N08904) is a low-carbon, high-alloy austenitic stainless steel that offers superior corrosion resistance compared to other grades like 304 and 316. Its high nickel, molybdenum, and copper content enhances resistance to reducing acids and chloride attack.

This alloy was originally developed for use in aggressive chemical environments, particularly where sulfuric acid is present. Today, it’s widely used for applications where both mechanical strength and corrosion resistance are critical.

Chemical Composition of SS 904L:

• Chromium (Cr): 19 – 23%

• Nickel (Ni): 23 – 28%

• Molybdenum (Mo): 4 – 5%

• Copper (Cu): 1 – 2%

• Carbon (C): Max 0.02%

• Iron (Fe): Balance

This composition provides the alloy with exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking.

SS 904L Pipe Manufacturing Excellence

As a reputed SS 904L Pipe Manufacturer, we follow a systematic and high-precision production process. Our facility is equipped with advanced machinery and quality control systems that ensure superior dimensional accuracy and flawless performance.

1. Raw Material Selection

We source only high-quality stainless steel billets and coils from certified suppliers. Each batch is tested for its chemical composition and mechanical properties before processing.

2. Hot Forming and Extrusion

In seamless pipe production, solid billets are heated and pierced to create a hollow tube. The tube is then elongated and sized using extrusion or pilgering techniques. For welded pipes, SS 904L sheets are rolled and joined using TIG or laser welding.

3. Heat Treatment

Pipes undergo solution annealing at temperatures between 1090°C and 1175°C, followed by rapid cooling. This step enhances the material’s corrosion resistance and ductility.

4. Pickling and Surface Cleaning

Pipes are treated with acid solutions to remove scale and impurities, ensuring a smooth, clean surface finish.

5. Inspection and Testing

To guarantee quality, our SS 904L pipes undergo:

• Hydrostatic Pressure Test

• Eddy Current Test

• Ultrasonic Test

• Dimensional and Visual Inspection

• Flattening and Flaring Tests

6. Finishing and Marking

Pipes are polished (bright or mirror finish) as per customer requirements. Each pipe is marked with grade, size, standard, and heat number before packaging.
