Stainless Steel 316H Tubes Manufacturer

Silver Tubes manufactures and exports Stainless Steel 316H tubes from our stocking yard in Mumbai, India. Buyers approach us as a stainless steel 316H tube supplier when a line runs hot and the lower carbon grades begin to creep. The 316H grade carries 0.04 to 0.10% carbon, and that carbon is what holds tensile strength together above 500°C. Molybdenum at 2 to 3% covers the corrosion side, including pitting in chloride service. As a stainless steel 316H tubes manufacturer, we supply the grade in seamless and welded form, in outside diameters from 6 mm to 219 mm, with wall thickness cut to drawing. Material conforms to ASTM A213, A249, A269, and matching ASME SA specifications.

Why Choose Silver Tubes?

Silver Tubes runs as a professionally managed export house built by a young promoter team, and stock depth is where we compete. Our Mumbai warehouse carries every size in our supply scope, so most orders ship immediately instead of waiting on a mill run. Each lot passes an in-house quality check, and we arrange third party inspection whenever your specification calls for it. Customization is routine here: odd lengths, non-standard wall thickness, and mixed grade orders. Pricing stays competitive because we buy and stock in volume. Consignments leave on the committed date, which repeat buyers value most. Contact our desk for a quote against your size and quantity.

What is Stainless Steel 316H Tube?

Stainless Steel 316H tube is the high carbon variant of the 316 austenitic family. It shares the same base chemistry: 16 to 18% chromium, 10 to 14% nickel, and 2 to 3% molybdenum. Carbon is the only real point of difference. Standard 316 caps carbon at 0.08%, while the H grade holds a controlled band of 0.04 to 0.10%. That extra carbon forms stable carbides inside the grain structure, which is why 316H keeps its creep rupture strength through continuous service at 870°C. Minimum tensile strength sits at 515 MPa against a 205 MPa yield. The grade also specifies a coarser grain size, ASTM No. 6 or coarser, and resists sulfuric acid in process piping.

Features & Benefits of Stainless Steel 316H Tubes

  • High temperature strength: The tube holds its mechanical properties at 870°C continuous, 925°C intermittent.
  • Creep resistance: Above 500°C under sustained load, the coarse grain structure resists deformation better than 316L.
  • Corrosion resistance: Molybdenum at 2 to 3% blocks pitting and crevice attack in chloride and acidic media.
  • Weldability: Every standard fusion method applies. Specify solution annealing after welding on heavy wall sections.
  • Long service life: Predictable wall loss extends replacement intervals in superheater and heat exchanger bundles.
  • Oxidation resistance: The chromium oxide film re-forms after each thermal cycle, so scaling stays light.
  • Durability: Thermal shock and pressure cycling cause no measurable loss of ductility.
  • Easy fabrication: Tubes bend, flare, and expand cold at standard tube sheet ratios without cracking.

Frequently Asked Questions

Carbon separates the two grades. 316H holds 0.04 to 0.10%; standard 316 caps it at 0.08%.

Yes. The grade runs continuously at 870°C and tolerates 925°C intermittently.

We supply against ASTM A213, A249, A269, and A312, plus equivalent ASME SA grades.

Yes. Our mill produces outside diameters, wall thicknesses, and cut lengths to your drawing.

Yes. Both forms ship from stock. Seamless suits high pressure duty; welded works on lower pressure lines.

Refineries, power plants, petrochemical units, and heat exchanger fabricators order this grade regularly.

Yes. As an SS 316H tube supplier, we ship from Mumbai to the Gulf, Europe, Africa, and the Americas.
