Steelage Alloys has been rated among the top manufacturers, suppliers, dealers, and exporters of SS 304 Seamless Pipes in India. Our products are available in the best quality stainless steel and are made to the standards of the best industry. We are producing Stainless Steel 304 304 Seamless Pipes with high grade raw materials and advanced production methods.We use high grade raw materials and modern manufacturing methods in producing Stainless Steel 304 304 Seamless pipes. The SS 304 is a very flexible and widely used grade of stainless steel since it has good resistance to corrosion, high strength, as well as durability. Our seamless pipes are unique in the sense of their smooth surface, the correct size, and long life as they can be used in a variety of applications.

Introduction to Stainless Steel 304 Seamless Pipes

The seamless pipes which are SS 304 form the foundation of the modern day industrial piping because of their resistance to corrosion, strength and versatility. They are also austenitic stainless steel that has 18 percent chromium and 8 percent nickel, which means that they are suitable in high temperature and high-pressure application and where high hygiene and reliability are important. The seamless pipes are produced without welded joints and without any welding resulting in consistent mechanical properties and leak-free performance.

Why Choose SS 304 Seamless Pipes?

  • Excellent corrosion resistance in various environments
  • High mechanical strength and toughness
  • Superior weldability and formability
  • Hygienic properties suitable for food and pharmaceutical industries
  • Leak-proof construction essential for critical high-pressure applications

Manufacturing Process Overview

  • Pipes are produced using extrusion and pilgering from stainless steel billets.
  • Solution annealing process is adopted to relieve stresses and provide uniform mechanical properties.
  • Non-destructive testing (NDT), hydrostatic testing, and ultrasonic inspection are performed to assure quality.
  • Dimensional checks including wall thickness, diameter, and length are meticulously verified.

Key Features and Benefits of SS 304 Seamless Pipes

  • High Corrosion Resistance – Performs exceptionally well in acidic and oxidizing environments.
  • Excellent Weldability – Easy to fabricate and join using standard welding methods.
  • Temperature Resistance – Retains strength and stability at high temperatures.
  • Smooth Finish – Seamless design offers a clean, polished surface ideal for hygiene-critical industries.
  • Long Service Life – With minimal maintenance, these pipes offer extended durability.

Chemical Composition of SS 304
