1. Understanding 316 Stainless Steel Pipes

1.1 What is 316 Stainless Steel?

316 stainless steel is an austenitic chromium-nickel alloy that contains molybdenum, enhancing its resistance to corrosion, pitting, and crevice corrosion—especially in chloride-rich environments (e.g., seawater, chemical processing).

1.2 Key Properties

- Corrosion Resistance: Superior to 304 stainless steel due to molybdenum content.

- High-Temperature Strength: Maintains structural integrity at elevated temperatures.

- Weldability & Formability: Easy to fabricate and weld.

- Hygienic Properties: Ideal for food, pharmaceutical, and medical applications.

1.3 Common Types of 316 Stainless Steel Pipes

- Seamless Pipes: No welded joints, ideal for high-pressure applications.

- Welded Pipes: Cost-effective for general-purpose use.

- Schedule 10/40/80: Different wall thicknesses for varying pressure requirements.
