Stainless Steel 304 Pipes

Stainless Steel 304 pipe is renowned for its remarkable chemical composition and outstanding strength. The chief elements of SS 304 pipes are iron, chromium, and nickel, along with other minor elements such as carbon, nitrogen, and manganese. It is a standard 18/8 alloy in various forms and finishes compared to other grades. These work together to make the ss 304 pipes resistant to oxidation, corrosion, and many chemicals, including those that require heat resistance. 304 pipe also has a low thermal conductivity, limiting the loss of heat from piping systems. It’s easy to see why 304 stainless steel is considered one of the most versatile alloys today!

304 stainless steel pipe is an incredibly versatile material with many advantages when it comes to plumbing and water transportation. It can be readily sourced from any 304 stainless steel pipe supplier, and with many different lengths, thicknesses, and bends available, it can easily be tailored to fit almost any application. 304 stainless steel pipe price lists are competitive for such a high-quality product, but the variety of sizes ensures cost savings since exact measurements can be ordered. Furthermore, providing long-lasting performance for years to come.

304-grade stainless steel has a stable austenitic structure, which makes it possible to be deep-drawn without immediate annealing. UNS S30400 can be brake or rolled and formed into different components for industrial, transportation, and architectural purposes. Pitting and crevice corrosion can be of concern in warm chloride environments. AISI 304 stainless steel may also undergo stress corrosion cracking at temperatures above 60 degrees Celsius. High-temperature strength executed by 304-grade pipes makes them usable in structural and pressure-containing applications. 304 pipes are used in applications like food processing equipment, kitchen appliances, heat exchangers, architectural paneling, chemical containers, threaded fasteners, and other industrial purposes.

304 pipe can be available in various finishes and sizes to meet the application requirements from our list of trusted suppliers and manufacturers.

Stainless Steel 304 Pipe covers a wide range of sizes according to the ASTM, ASME, and API standards. The range includes welded SS 304 pipes and electric fusion welded pipes. The nominal bore size of a Stainless Steel 304 Seamless Pipe ranges from ½ inches to 16 inches, its ERW pipes range from ½ inches to 24 inches, and its EFW pipes range from 6 to 100 inches. All pipe sizes range from 1/8 inch to 30 inches.

The pressure rating for 304 stainless steel pipe depends on the pipe size and schedule. Generally, the higher the wall thickness or schedule number, the higher the pressure rating. For example, a 1-inch Schedule 40 pipe has a pressure rating of 310 PSI, while a 1-inch Schedule 80 pipe has a pressure rating of 580 PSI.

The price of 304 stainless steel per square foot in Indian Rupees (INR) will depend on the current exchange rate. Generally, it is estimated that 304 stainless steel costs between ₹222 and ₹1,110 per square foot when converting from USD to INR. However, this price can fluctuate depending on the current exchange rate.

The price of a 304 stainless steel pipe will depend on the desired size, length, and grade of material. Generally speaking, prices for smaller-sized pipes can range from ₹1,163 to ₹3,855 per meter in India. Larger-sized pipes 4 inches or larger and usually priced between ₹4,000 and ₹7,000 per meter; this can vary depending on availability and grade.

Stainless steel 304 is a versatile material widely used in constructing pipes and pipe fittings. The following are some of the critical specifications for 304 stainless steel pipes:

  • ASTM A312: Standard specification for seamless, welded, and heavily cold-worked austenitic stainless steel pipes.
  • ASTM A358: Standard specification for electric-fusion-welded austenitic chromium-nickel stainless steel pipe for high-temperature service.
  • ASTM A376: Standard seamless austenitic steel pipe specification for high-temperature central station service.
  • ASTM A778: Standard specification for welded, unannealed austenitic stainless steel tubular products.
  • ASME SA312: Standard specification for seamless, welded, and heavily cold-worked austenitic stainless steel pipes.

The pressure rating of 304 Stainless Steel pipes is determined based on the material's yield strength, which ranges from 25 to 40 ksi (kilopounds per square inch). For example, a Type 304 stainless steel pipe with an outer diameter of 2 inches and a wall thickness of 0.25 inches has a pressure rating range of 20-30 KSI. For larger diameters and thicker walls, the pressure rating increases accordingly. The temperature can also affect the pressure rating of these pipes, as higher temperatures may lead to decreased strength.

304 stainless steel pipes are available in a wide range of sizes. The most commonly used sizes are:

  • NPS (National Pipe Size): 1/8" to 12"
  • DN (Diameter Nominal): 6 to 300

In terms of wall thickness, 304 stainless steel pipes are available in several schedules, including:

  • Schedule 5: Wall thickness of 0.083 inches (2.11 mm) and above
  • Schedule 10: Wall thickness of 0.109 inches (2.77 mm) and above
  • Schedule 40: Wall thickness of 0.133 inches (3.38 mm) and above
  • Schedule 80: Wall thickness of 0.179 inches (4.55 mm) and above
