Product Description

Product Description

Introduction

HAYNES 25 alloy (UNS R30605) is a cobalt-nickel-chromium-tungsten alloy that combines excellent high-temperature strength with good resistance to oxidizing environments up to 1800°F (980°C) for prolonged exposures, and excellent resistance to sulfidation. It can be fabricated and formed by conventional techniques, and has been used for cast components. Other attractive features include excellent resistance to metal galling.

• Characteristic
•  
• Outstanding high temperature strength
• Oxidation resistant to 1800° F
• Galling resistant
• Resistant to marine environments, acids and body fluids

 

Corrosion Resistance

HAYNES 25 (L605) resistance to high temperature oxidation and carburization is good. The alloy, while not primarily intended for aqueous corrosion, is also resistant to corrosion by acids such as hydrochloric and acid, as well as being resistant to wet chlorine solutions.

Density: 0.330 lbs./cubic inch

Technology

Machinability
Traditional machining methods and tooling such as carbide tools or high-speed steel tools can be used for HAYNES(r) 25. However it is not suitable to use carbide tools while milling, drilling or tapping. In these cases, it is better to use only high-speed steel tools

Forming
HAYNES(r) 25 can be formed by machining, cold working, welding, and forging.

Welding
HAYNES(r) 25 is weldable using metal-arc welding, gas-tungsten arc welding, and shielded metal-arc welding. It is not suitable to use submerged-arc welding method.

The surface to be welded should be clean and free from hydrocarbon products or grease.

Forging
HAYNES(r) is basically forged in the annealed condition for optimum properties.

Hot Working
Hot working of HAYNES(r) 25 can be performed if required.

Cold Working
HAYNES(r) 25 can be cold worked using conventional tooling.

Annealing
Solution annealing of HAYNES(r) 25 can be performed in case of extreme cold working at 1204°C (2200°F) and then followed by air cooling.

Aging
Age-hardening heat treatment can be performed on HAYNES(r) 25 at 482°C (900°F) after solution annealing heat treatment is completed.

Hardening
HAYNES(r) 25 can be hardened by cold working only. If required an aging heat treatment can be performed to slightly improve hardness and strength.

Applications

 

• Gas turbine engine combustion chambers and afterburners
• High temperature ball bearings and bearing races
• Springs
• Heart valves

HAYNES(r) 25 can be used in gas turbine high temperature components and industrial furnace applications such as liners, muffles, and structural parts.
