What is Stainless Steel 316 Welded Tubing?

Stainless steel 316 welded tubing is manufactured by rolling and welding flat strips or plates of grade 316 stainless steel into cylindrical shapes. The tube is perfect for structural and fluid transfer applications, as the welding process produces a strong, clean seam.Β  Its high molybdenum content provides exceptional resistance to corrosion, particularly from aggressive cleaning agents, acids, and chlorides. They are a durable, effective option made for applications, require both formability and strength. It effectively manages fabrication, bending, and welding without sacrificing integrity. These durable Stainless Steel 316 Tube Properties make it an ideal choice for engineers and decision-makers working in harsh or hygiene-critical environments.

Benifits of Stainless Steel 316 Welded Tubing

Benefits of Stainless Steel 316 Welded Tubing

The Benefits of 316 Stainless Steel Tubing are known for its balanced performance, durability, and ease of use.

  • Excellent corrosion resistance: Resists damage from acids, chlorides, and harsh cleaning agents. Delivers long-term surface integrity in corrosive environments.
  • High strength and heat resistance: Withstands high temperatures and mechanical stress without losing form or reliability.
  • Cost-effective compared to seamless tubing: Offers a balance of strength, quality, and affordability. A smart option when seamless tubes aren’t necessary.
  • Easy fabrication and welding: Welded construction simplifies handling, shaping and joining. Cuts down on fabrication time and effort.
  • Reliable under long-term pressure: Maintains form and strength under constant use. Known for its extended service life and low maintenance needs.

316 vs 304 Welded Stainless Steel Tubing – Key Differences

When choosing between Stainless Steel Welded Tubing grades 304 and 316, the decision typically depends on the working environment, expected exposure to corrosive elements, and budget considerations.

Offers Better Corrosion Resistance
The biggest difference between 304 and 316 welded tubing is the presence of molybdenum in 316. Its resistance to acids, chlorides and industrial chemicals is increased by this addition which makes it the best choice in harsh situations.

More cost-effective for standard applications
Β If your project doesn’t involve harsh chemicals, saltwater, or acidic solutions, Stainless Steel 304 Welded Tubing is a smart, budget-friendly option. It performs well in dry indoor settings, architectural frameworks, and general fabrication.

Excels in Harsh or Chemical-Rich Environments
Β Salt spray, seawater, and chemical vapors can quickly break down standard stainless steel. That’s where 316 is ideal, commonly found in marine fittings, boat rails, offshore platforms, and chemical tanks.

Works Well in Food Prep and Residential Areas
With good resistance to oxidation and most mild chemicals, 304 works great in food prep equipment, sinks, countertops, and freshwater pipelines where exposure isn’t overly aggressive.

Preferred in Hygienic and High-Cleanliness Applications
Environments with regular washdowns or contact with acids require metal that won’t corrode or contaminate. 316 tubing excels here, especially in pharmaceutical lines, dairy plants, breweries and commercial kitchens.

Durability and lifecycle costs
While 316 is more costly initially, it pays over time by decreasing maintenance, corrosion-related failures and part replacements, particularly in harsh situations. When comparing 316 vs 304 SS tube it’s important to weigh performance over time, not just initial pricing.

The difference between 304 and 316 welded tubing is determined by the environment, exposure, and the amount of time the tubing is expected to function properly.

Heat & Corrosion Resistance Ratings

SS 316 welded tubing offers excellent heat and corrosion resistance, making it ideal for demanding industrial and marine applications. It can withstand intermittent high-temperature exposure up to 925Β°C (1697Β°F) and continuous service temperatures up to 870Β°C (1598Β°F) without loss of strength or oxidation issues. The presence of molybdenum enhances its resistance to chloride-induced pitting and crevice corrosion, which are common in seawater, brine, and chemical processing environments. This makes SS 316 welded tubing highly durable and reliable, even in acidic or aggressive media, ensuring long-term performance with minimal degradation.

SS Welded 316 Tubing Manufacturing Process

We manufacture SS 316 welded tubing using advanced processes to ensure superior corrosion resistance, weld integrity, and precise dimensions.

SS Welded 316 Tubing Manufacturing Process
  • High-quality 316 stainless steel strips or coils are selected as raw material.
  • The strips are formed into tubes using precision roll forming techniques.
  • Automatic Tungsten Inert Gas (TIG) welding ensures a strong, clean weld seam.
  • Welded tubes undergo solution annealing to enhance mechanical properties and corrosion resistance.
  • Pickling and passivation are performed to remove heat tint and restore the stainless steel’s corrosion resistance.
  • Non-destructive testing, such as eddy current and ultrasonic testing, verifies weld integrity and internal soundness.
  • Final dimensional and surface inspections are carried out in accordance with ASTM A269 or ASTM A249 standards.

Packaging & Delivery of ASTM A312 TP316 Welded Tubing
