Product Description:

304 and 304L ss forged fittings are highly versatile, corrosion-resistant components designed for piping systems that demand durability, strength, and superior resistance to chemical and environmental factors. These forged fittings are ideal for both low and high-pressure applications across various industries.

304 Stainless Steel

  • Often referred to as “18/8 stainless steel” due to its composition of 18% chromium and 8% nickel.
  • Offers excellent corrosion resistance, good strength, and weldability.
  • Suitable for general-purpose applications.

304L Stainless Steel

  • A low-carbon version of 304, designed to minimize carbide precipitation during welding.
  • Provides enhanced weldability and resistance to intergranular corrosion.
  • Ideal for use in environments where welding is required.

Key Features of 304/304L Stainless Steel Forged Fittings

  • Corrosion Resistance: Exceptional resistance to oxidation, pitting, and crevice corrosion in a wide range of environments.
  • High Strength and Durability: Excellent tensile and yield strength for demanding applications.
  • Heat Resistance: Performs well in temperatures up to 870°C in intermittent service and 925°C in continuous service.
  • Weldability: Suitable for welding with or without filler metals.
  • Ease of Fabrication: Can be readily machined, formed, and fabricated.

Common Applications

  • Chemical and Petrochemical: Processing and handling of chemicals and gases.
  • Food Processing: Equipment for food production and storage.
  • Pharmaceutical: High-purity systems for medical and pharmaceutical use.

FAQ

What is the difference between 304 and 304L stainless steel forged fittings?

The primary difference lies in the carbon content: 304L has a lower carbon content, making it more suitable for welding applications and reducing the risk of intergranular corrosion.

Can 304/304L stainless steel forged fittings be used in high-pressure systems?

Yes, these fittings are available in pressure classes up to 9000 and are ideal for high-pressure applications in various industries.

Are these fittings suitable for food-grade applications?

Absolutely! Both 304 and 304L stainless steel are commonly used in food processing equipment due to their excellent corrosion resistance and ease of cleaning.
