ASME SB444 N06625 Inconel 625 Nickel Alloy Tube For Heat Exchanger, Marine Offshore Oil Gas & Chemical Processing

ASME SB444 N06625 (UNS N06625 / Alloy 625 / Inconel 625) is an austenitic superalloy pipe with a nickel-chromium matrix and solid solution strengthened by molybdenum and niobium. It is technically equivalent to the ASTM B444 standard. Due to its extremely high strength, excellent corrosion resistance, and good machinability, it has become the material of choice for critical components in many advanced industrial fields.

The ASME SB444 standard specifically addresses cold-worked seamless pipes and tubing, covering UNS N06625 and its variants, and is a key basis for the application of materials in the ASME Boiler and Pressure Vessel Code. Pipes under this standard are classified into two grades according to their heat treatment state to suit different working environments:

Grade 1 (annealed): Suitable for conventional high-temperature environments up to approximately 593°C (1100°F).

Grade 2 (solution annealed state): Suitable for high-temperature conditions above 593°C (1100°F) where higher requirements are placed on creep and fracture strength.

	Annealing – Grade 1	Solution Annealing – Grade 2
Typical Applications	Oil&Gas: production piping, riser liners	High-temperature combustion systems: refinery and offshore platform burners
	Chemical industry: superphosphoric acid equipment	Hot gas treatment: heat exchangers, expansion joints
	Marine engineering: seawater piping systems	Waste incineration: superheater tube panels
	Nuclear waste treatment equipment	Aerospace: high-temperature components
Selection Criteria	Applications requiring both high strength and excellent corrosion resistance, with service temperatures not exceeding 593°C (1100°F)	Applications where service temperatures exceed 593°C (1100°F) and long-term creep resistance is a critical requirement

Chemical Composition

Element	Composition (wt%)
Nickel (Ni)	Balance (≥ 58.0)
Chromium (Cr)	20.0 – 23.0
Molybdenum (Mo)	8.0 – 10.0
Niobium + Tantalum (Nb+Ta)	3.15 – 4.15
Iron (Fe)	≤ 5.0
Carbon (C)	≤ 0.10
Manganese (Mn)	≤ 0.50
Silicon (Si)	≤ 0.50
Phosphorus (P)	≤ 0.015
Sulfur (S)	≤ 0.015
Aluminum (Al)	≤ 0.40
Titanium (Ti)	≤ 0.40
Cobalt (Co)	≤ 1.0

Mechanical Properties

Property	Grade 1 (Annealed)	Grade 2 (Solution Annealed)
