Product Description

Product Description

 

Introduction

LORK is a special stainless steel manufacturer with 20 years of manufacturing experience.
 

Alloy 660 is a precipitation hardening austenitic stainless steel known for its impressive strength at high temperatures up to 700°C. Also sold under the names, UNS S66286, and A-286 alloy, Alloy 660 gains its strength from a high degree of uniformity. It has an impressive yield strength minimum of 105,000 psi and is commonly used in high temperature fastening and bolting materials.

Stainless Steel 660 Applications

- Gas turbine forgings, 
- Fasteners, 
- Superchargers, 
- Cryogenic equipment, 
- Missile components, 
- Corrosive deep well hardware 
- Jet engines.

Cold working

Super alloy A-286 is capable of being readily cold worked and a solution anneal heat treatment is recommended when this alloy is work hardened due to severe cold forming. This solution anneal heat treatment will thus enable softening of super alloy A-286.
Welding
Welding methods used for stainless steels are also recommended for super alloy A-286. The area to be welded should be clean. Post welding heat treatment or preheating is not recommended for this alloy. Better welding results can be obtained when this alloy is solution annealed.
Forging
Heavy forging and light forging are suitable for super alloy A-286. Heavy forging is carried out between 1010-1204°C (1850-2200°F) and light forging between 871-1010°C (1600-1850°F).
Forming
Conventional forming methods are used to readily hot or cold form super alloy A-286.
Machinability
Conventional machining techniques are used to readily machine super alloy A-286. This machining process involves turning, drilling and milling. In the turning operations, the usage of cemented carbide tools is recommended for high cutting rates.
Aging
Super alloy A-286 is first solution heat treated at 982°C (1800°F) before the aging process. Aging takes place for 16 h at 718°C (1325°F) after which this alloy is cooled in air.
Hardening
Super alloy A-286 is hardened by the cold working process and is also capable of being age hardened due to the presence of titanium in this alloy.
Heat Treatment
Super alloy A-286 is solution annealed at 982°C (1800°F), oil quenched, held for 16 h at 718°C (1325°F) and finally cooled in air. This heat treatment improves the strength of super alloy A-286.
