Inconel Tube Manufacturer & Supplier

Inconel tube is a nickel-chromium superalloy tubular product designed for extreme temperatures and corrosive environments. These tubes come in grades 600 and 625, each with a distinct balance of nickel, chromium, molybdenum, and niobium. Inconel 600 contains 72% minimum nickel with 14 to 17% chromium, while Inconel 625 adds 8 to 10% molybdenum and 3.15 to 4.15% niobium. Tensile generally stays around 550 MPa (80 ksi) in annealed Alloy 600.

Inconel Tube Grades

Inconel tubes come in 2 primary grades targeting specific operating conditions.

Inconel 600 Tube (ASTM B163 / ASTM B167)

Inconel 600 tube contains 72% minimum nickel with 14 to 17% chromium. It resists chloride stress corrosion cracking and oxidation up to 1100°C (2012°F), serving nuclear steam generators and furnace equipment.

Inconel 625 Tube (ASTM B444)

Inconel 625 tube is solid-solution-strengthened with 8 to 10% molybdenum and 3.15 to 4.15% niobium. Annealed tubing delivers 827 MPa (120 ksi) minimum tensile strength for offshore oil and gas and chemical processing.

Inconel Tube Price

The pricing of Inconel 600 tube ranges from Rs 800 to 5,000 per kg in India and US $10 to $60/kg internationally. For 625, it goes from Rs 2,000 to 12,000 per kg in India and US $25 to $150/kg overseas. The final price depends on grade, size, form, and quantity.

Inconel Tube Industrial Applications

Inconel tubes serve 5 major industries where high-temperature and corrosion resistance are critical.

Aerospace & Gas Turbine

Inconel 625 tubing is used in jet engine fuel lines, exhaust ducting, and turbine cooling above 650°C.

Chemical Processing

Inconel 625 tubes reliably carry aggressive acids and chloride-bearing process streams in high-pressure, high-temperature chemical reactors.

Oil & Gas

Subsea umbilicals and downhole control lines use Inconel 625 tubing for sour gas (H2S) resistance per NACE MR0175.

Nuclear Power & Heat Exchangers

In the nuclear power sector, Inconel 600 tubes serve as steam generator tubing in pressurised water reactors.

Heat Exchangers & Condensers

ASTM B163 Inconel tubes are specified for heat exchangers and condensers handling seawater and corrosive media.

Inconel Tube vs Stainless Steel Tube

The table given below compares the two most favourable grades of their respective materials.
Inconel tubes outperform SS 316 above 650°C (1200°F) and in chloride stress corrosion cracking environments.

Property	Inconel 625 Tube	SS 316 Tube
Max Service Temperature	980°C (1796°F)	870°C (1598°F)
Tensile Strength (Annealed)	827 MPa (120 ksi)	515 MPa (75 ksi)
Chloride SCC Resistance	Excellent	Susceptible
Cost (per kg)	US $25 to $150	US $3 to $15

SS 316 suits moderate temperatures at a lower cost; Inconel is preferred for severe corrosion and high-temperature service.

What is the price of Inconel Tube per kg? +

Inconel 600 tubes cost Rs 800 to 5,000 per kg in India and US $10 to $60/kg internationally. Inconel 625 ranges from Rs 2,000 to 12,000 per kg in India and US $25 to $150/kg in other countries. Price depends on size, quantity, and market conditions.

What sizes are available for Inconel Tubes? +

Seamless Inconel tubes range from 1/4 inch to 12 inch OD. Wall thicknesses span 0.035 inch (0.89 mm) to 0.500 inch (12.70 mm). Custom sizes are available.

Can Inconel Tubes be bent? +

Inconel tubes can be bent using cold, hot, or mandrel methods. Annealed (Grade 1) tubes offer better formability.

What ASTM standards cover Inconel Tubes? +

ASTM B163 (heat exchanger tubes), ASTM B167 (600/601), and ASTM B444 (625) cover Inconel tubes.

What is the difference between Inconel Tube and Stainless Steel Tube? +

Inconel outperforms SS 316 above 650°C and in chloride SCC environments. SS 316 costs less for moderate temperatures.

How do I select the right Inconel Tube grade? +

Choose Inconel 600 for general high-temperature oxidation, Inconel 625 for severe chloride and acid corrosion.
