Inconel 600 Seamless Pipe with Creep Rupture Strength Above 700°C and Excellent Oxidation Resistance for Corrosion Resistant Applications

1. Product Attributes

Inconel 600 (UNS N06600 / EN 2.4816 / NCF 600) is a nickel-chromium alloy containing 14-17% Cr. It exhibits excellent oxidation resistance at high temperatures and is classified as a high-grade heat-resistant alloy. It demonstrates excellent corrosion resistance to various acidic and alkaline environments, making it widely used as a corrosion-resistant alloy in critical industrial applications.

2. Material Overview

Inconel 600 Alloy is a nickel-based alloy containing 14-17% Cr. It exhibits excellent oxidation resistance at high temperatures and is classified as a high-grade heat-resistant alloy. Furthermore, it demonstrates excellent corrosion resistance to various acidic and alkaline environments, making it widely used as a corrosion-resistant alloy. The alloy is specified under NAS 600 (US Standard), UNS N06600, EN 2.4816, and JIS NCF 600.

Key Characteristics:

• High-Temperature Oxidation Resistance: Excellent oxidation resistance at high temperatures; suitable for various environments except long-term continuous air oxidation.
• Corrosion Resistance: Excellent resistance to reducing, oxidizing, and nitriding media; outstanding stress corrosion cracking resistance at all temperatures.
• Creep Rupture Strength: Excellent creep rupture strength; recommended for use in environments above 700°C.
• Mechanical Properties: Superior mechanical properties at sub-zero, room, and high temperatures.
• Chlorine/HCl Resistance: Excellent resistance to dry chlorine and hydrogen chloride gases.

7. Material Characteristics

• Excellent Resistance to Reducing, Oxidizing, and Nitriding Media: Inconel 600 offers exceptional corrosion resistance across all three corrosive regimes. Its Cr content provides superior oxidation resistance, while high Ni content ensures outstanding performance in reducing environments.
• Excellent Stress Corrosion Cracking Resistance: Demonstrates outstanding resistance to stress corrosion cracking at both room temperature and high temperatures — a distinct advantage over standard austenitic stainless steels in chloride-containing environments.
• Excellent Dry Chlorine and HCl Gas Resistance: Provides reliable resistance to dry chlorine and hydrogen chloride gases, making it a preferred choice for chlorination processes and HCl production.
• Superior Mechanical Properties at All Temperatures: Maintains excellent mechanical strength and ductility from sub-zero temperatures through to 700°C+ operating conditions.
• Excellent Creep Rupture Strength Above 700°C: Recommended for applications above 700°C where long-term creep strength is critical. At 982°C, offers 30 MPa (10 hr) and 13 MPa (1000 hr) creep fracture strength.
• Good Weldability: Can be welded using TIG, MIG, and manual arc welding methods comparable to standard austenitic stainless steels.
