Product Description

Alloy 601 Offshore Flange Pipeline Forged Flange

Material Overview

Alloy 601, also known as Inconel 601 or UNS N06601, is a high-temperature, oxidation-resistant nickel-chromium alloy designed for demanding industrial applications. Its consistent chemical composition ensures reliable performance across various standards and suppliers.

Chemical Composition

Element	Composition (% by weight)
Nickel (Ni)	58.0–63.0%
Chromium (Cr)	21.0–25.0%
Iron (Fe)	Balance (remainder after other elements)
Aluminum (Al)	1.0–1.7%
Carbon (C)	≤ 0.10%
Manganese (Mn)	≤ 1.0%
Silicon (Si)	≤ 0.50%
Sulfur (S)	≤ 0.015%
Copper (Cu)	≤ 1.0%

Additional specifications may include Titanium (Ti) up to approximately 0.6% maximum, typically at very low or residual levels.

Key Element Functions

High Nickel (Ni) Content
- Provides excellent high-temperature strength
- Ensures resistance to corrosive environments
- Maintains toughness and stability at elevated temperatures
High Chromium (Cr) Content
- Delivers strong oxidation resistance in air at high temperatures (up to 1100–1200°C)
- Forms a stable, protective oxide layer on the surface
Aluminum (Al) Addition
- Enhances resistance to high-temperature oxidation
- Reduces spalling (flaking) of the oxide scale
- Improves performance in cyclic heating conditions
Iron (Fe) as Balance
- Helps control manufacturing costs
- Adjusts mechanical properties while preserving high-temperature capability

Typical Applications

Furnace components and heat-treating equipment
Petrochemical processing equipment
Catalyst support grids
Combustion chambers
High-temperature fixtures

Important Note: For design, welding, or material selection purposes, always verify the exact composition limits in relevant standards (such as ASTM B166/B167/B168 for N06601) or consult material certificates from suppliers, as minor variations may exist between producers and product forms.
