316 Pipe

Stainless Steel 316 Pipe: Superior Welding & Forming Performance

 316 stainless steel pipe is a type of austenitic stainless steel pipe known for its excellent corrosion resistance, particularly in harsh environments.
It is readily brake or roll formed into a variety of parts for applications in the industrial, architectural, and transportation fields.

Main Alloying Elements

Chromium (Cr)

~16-18%
(Provides corrosion resistance)

Nickel (Ni)

~10-14%
(Enhances ductility & toughness)

Molybdenum (Mo)

2-3%
(key for resisting chlorides & acidic environments)

Carbon (C)

Low
(Typically ≤0.08%, improves weldability)

Manganese (Mn)

≤2%
Aids in hot workability.

Silicon (Si)

1%
Enhances strength and oxidation resistance.

Phosphorus (P)

≤0.045%
Trace elements (improve machinability).

Sulfur (S)

≤0.045%
Trace elements (improve machinability).

Advantages

  • Superior corrosion resistance.
  • Good high-temperature strength (up to ~870°C / 1600°F intermittently).
  • Excellent formability and weldability.

Standards & Certifications

ASTM A312

(Seamless/welded pipes for high-temp service).

ASTM A269

(Stainless tubing for general corrosion resistance).

ASME SA312/SA269

(Pressure vessel applications).

Common Applications

  • Marine environments (shipbuilding, offshore platforms).
  • Chemical & pharmaceutical processing (acid-resistant pipes).
  • Food & beverage industry (sanitary tubing).
  • Medical devices & surgical instruments.
  • Architectural applications in coastal areas.

Types of 316 Stainless Steel Pipes

  • Seamless Pipes: Higher pressure resistance, used in critical applications.
  • Welded Pipes: More economical, suitable for low/medium-pressure systems.
  • Schedule Variants: Sch 10, 40, 80, 160 (thickness varies for pressure requirements).
