Introduction
LORK is a special stainless steel manufacturer with 20 years of manufacturing experience.
Steel used for valve parts, tanks, CNC parts and tooling in aerospace industry. Resistant to acids and chlorides commonly occuring in river water. Sufficiently resistant to ammonia and nitrogen tetroxide in mild temperature. Rust may occure in a marine atmosphere.
The steel has better stress corrosion cracking resistance and resistance to reducing acids and chloride containing pleas than 1.4568 steel. It also has limited resistance to crevice corrosion and pitting.
Weldable, but less weldable than 17-4 PH, which is caused by high Al content.
632 Stainless Steel 15-7PH Applications
Grade 15-7 stainless steel is used in the following applications:
- Diaphragms
- Welded and brazed honeycomb panels
- Retaining rings
- Aircraft bulkheads
- Springs
- Other applications requiring high strength at elevated temperatures
Grade 15-7 stainless steel can be welded using common arc and resistance methods. Inert gas shielding is avoided in order to prevent oxidation of aluminum.
Annealing
Grade 15-7 stainless steel is annealed at 1038°C (1900°F) followed by cooling rapidly.
Machinability
Grade 15-7 stainless steel has good machinability in the hardened condition.
Cold Working
Grade 15-7 stainless steel is limited to cold working.
Hot Working
Grade 15-7 stainless steel has good hot working capacity. This process should be followed by annealing in order to respond heat treatment.
