Womic Stainless Steel Co., Ltd
316H Stainless Steel Pipe combines corrosion resistance, high-temperature strength, and structural reliability. Its increased carbon content enhances creep strength and improves mechanical stability at temperatures above 500°C.
Key characteristics include:
1.Excellent high-temperature strength and creep
resistance.
2.Superior corrosion resistance in chloride and chemical environments.
3.Good oxidation resistance under elevated temperature conditions.
4.Strong mechanical stability for high-pressure industrial systems.
5.High durability and long service life in harsh operating environments.
6.Good weldability and fabrication performance for industrial piping systems.
316H Stainless Steel Pipe is produced according to multiple international standards to ensure compatibility with global engineering projects.
Common standards include:
ASTM A312 / A213 / A269 – TP316H Stainless Steel Pipe and
Tube
ASTM A358 – Electric Fusion Welded 316H Stainless Steel Pipe
EN 10216-5 – 1.4401 / 1.4404 related grades
JIS G3459 – SUS316H Stainless Steel Pipe
GB/T 14976 – 06Cr17Ni12Mo2H Stainless Steel Pipe
These standards specify the chemical composition, mechanical properties, manufacturing requirements, inspection methods, and testing procedures necessary to ensure high-quality stainless steel pipes for industrial applications.
Womic Steel supplies316H Stainless Steel Pipesin a wide range of sizes to meet various engineering requirements.
Seamless Pipe Size Range:
OD: 6 mm – 630 mm

Wall Thickness: 2 mm – 40 mm
Standard pipe schedules available include SCH5, SCH10, SCH20, SCH40, SCH80, SCH160, and XXS.
Custom sizes and special specifications can also be produced according to project requirements.
The chemical composition of 316H Stainless Steel Pipe is carefully controlled to achieve both corrosion resistance and high-temperature mechanical performance.
Typical chemical composition (ASTM standard):
Carbon (C): 0.04 – 0.10%
Chromium (Cr): 16.0 – 18.0%
Nickel (Ni): 10.0 – 14.0%
Molybdenum (Mo): 2.0 – 3.0%
Manganese (Mn): ≤ 2.0%
Silicon (Si): ≤ 1.0%
Phosphorus (P): ≤ 0.045%
Sulfur (S): ≤ 0.03%
The presence of molybdenum significantly improves resistance to pitting and crevice corrosion, while the higher carbon content increases creep strength at elevated temperatures.
316H Stainless Steel Pipe provides reliable mechanical strength for both high-pressure and high-temperature environments.
Typical mechanical properties include:
Yield Strength: ≥ 205 MPa
Tensile Strength: ≥ 515 MPa
Elongation: ≥ 35%
Hardness: ≤ 201 HBW
These properties ensure that the pipe maintains structural integrity under demanding industrial conditions such as high-temperature steam systems and chemical processing plants.
Different specifications can be customized according to special requirements.

Womic Steel adopts advanced production technology to ensure each316H Seamless Stainless Steel Pipemeets exact specifications and flawless surface quality.
1. Raw Material Selection:High-quality316HStainless Steel Pipe billets from certified mills (Baosteel, TISCO, POSCO).
2. Heating and Piercing:Billets heated to a controlled temperature and pierced using a rotary piercing mill to form hollow shells.
3. Hot Rolling:Shells elongated and rolled to desired size.
4. Cold Drawing / Cold Pilgering:Pipes refined to precise dimensions and improved surface finish.
5. Solution Annealing:Heat treatment to restore corrosion resistance and ductility.
6. Pickling & Passivation:Removal of oxides and creation of passive film for enhanced corrosion protection.
7. Straightening and Dimensional Calibration:Ensures consistent roundness and wall uniformity.
8. Final Inspection & Marking:Each pipe tested, marked with grade, heat number, and standard before packing.
This process guarantees a smooth internal bore, high structural integrity, and exceptional corrosion resistance across all batches of Womic Steel’s316HSeamless Steel Pipe.
Womic Steel utilizes state-of-the-art manufacturing technology to ensure every316HWelded Stainless Steel Pipe meets precise specifications and delivers excellent surface quality and performance.
1. Raw Material Selection:High-quality316Hstainless steel strips/coils from certified suppliers (e.g., Baosteel, TISCO, POSCO).
2. Slitting & Uncoiling:The steel coil is slit to the required width and uncoiled for feeding into the forming mill.
3. Forming & Welding:The strip is progressively formed into a cylindrical shape and the edges are welded together using advanced TIG or Plasma welding techniques to create a solid weld seam.
4. Weld Seam Treatment:The external weld bead is removed to achieve a smooth surface, and the internal bead may be controlled or treated for bore cleanliness.
5. Solution Annealing:A full heat treatment process is applied to dissolve carbides, restore corrosion resistance, and relieve stresses from welding and forming.
6. Sizing & Calibration:The pipe is passed through a sizing mill to achieve the final precise outer diameter and roundness.
7. Straightening:The pipe is straightened to ensure optimal linearity.
8. Pickling & Passivation:Chemical treatment removes scale and impurities, while promoting the formation of a protective passive oxide layer on the surface, including the weld zone.
9. Non-Destructive Testing (NDT):The weld seam is inspected using methods like Eddy Current or Ultrasonic Testing to ensure integrity and quality.
10. Final Inspection & Marking:Each pipe undergoes dimensional checks, visual inspection, and is marked with grade, heat number, and relevant standards before packaging.
This controlled process guarantees a consistent weld seam, excellent dimensional accuracy, and superior corrosion resistance for every batch of Womic Steel's316HWelded Steel Pipes.
Outside Diameter:6mm – 1219mm (1/4" – 48")
