Stainless steel 304 is an alloy made of Chromium and Nickel. It is a grade of stainless steel that contains a minimum of 18% chromium and 8% nickel, in addition to a maximum of 0.08% carbon. A chromium content of at least 11% is necessary for the formation of the protective layer. It is not very electrically or thermally conductive and is non-magnetic. It has a higher corrosion resistance than regular steel and is widely used because of the ease in which it is formed into various shapes. Stainless Steel is highly ductile and has high strength.

Grade 304 of stainless steel is a standard “18/8” stainless that has high resistance to corrosion and oxidation due to the chromium content in it. It can be easily welded, has excellent toughness, even at cryogenic temperatures and can be easily fabricated. Stainless steel 304 has applications in a variety of purposes, like, in making utensils, screws, and various machinery parts.


Stainless Steel 304 Tube Fittings are a broad range of stainless steel fittings that are exclusively used in various pipelines and joints in various applications. The products available in the list of fittings are screwed ends and socket weld fittings, which includes elbow, tee, socket, reducer, reducing bushing, hose collar, hex nipple, barrel nipple, end cap and plug union. These products are available in all sizes and specifications and offer superior strength, great connectivity, and excellent rigidity. These fittings offer excellent weld ability with or without filler metals. They are designed to perform extremely well even in harsh conditions and are highly in demand. Stainless Steel 304 Tube fittings show great strength even at elevated temperatures and have excellent weld-ability with and without filler metals. These fittings offer zero leakage even under tough working conditions. Stainless Steel 304 Tube Fittings have good high-pressure corrosion/extreme temperature resistance. They are leak-proof joints that are capable of satisfying high-pressure vacuum and vibration applications

Typically, Stainless Steel 304 Tube Fittings are used in applications high reliability, extreme strength and great quality are required. They are also used in household premises and buildings.
