Performance and application of 310S stainless steel pipe

310S stainless steel pipe is a high-performance austenitic stainless steel known for its high chromium and nickel content, along with a low carbon composition. This combination gives it excellent heat resistance, corrosion resistance, and oxidation resistance, making it widely used in various industries.

Let’s explore its performance in detail through the following aspects:

1. Chemical Composition

The key elements in 310S stainless steel pipe include:

Chromium (Cr) – 20%: Enhances corrosion and oxidation resistance.

Nickel (Ni) – 8%: Improves heat resistance and strength.

Carbon (C) – 0.08%: Maintains structural integrity at high temperatures.

This composition ensures that 310S stainless steel pipe performs well in harsh environments, including high-temperature and corrosive conditions.

2. Physical Properties

310S stainless steel pipe is valued for its:

High hardness and wear resistance, thanks to its elevated chromium content.

Good toughness and plasticity, preventing fractures and allowing for various shaping processes.

3. Corrosion Resistance

310S stainless steel pipes exhibit outstanding corrosion resistance, including:

Resistance to high-temperature oxidation, maintaining structural integrity in extreme heat.

Strong protection against acids, alkalis, and salts, making it ideal for chemical industries.

Good resistance to chloride ion corrosion, preventing pitting and crevice corrosion.

Effective corrosion resistance in seawater, allowing for marine applications.

4. High-Temperature Performance

High melting point (~1475°C) ensures durability in extreme heat.

Excellent thermal stability allows it to maintain strength and structure over prolonged exposure to high temperatures.

Good cold working performance, making it adaptable to manufacturing techniques such as cold rolling and cold drawing.

5. Application Fields

Due to its superior properties, 310S stainless steel pipe is widely used in industries such as:
