Stainless Steel 15-5PH Pipe Fittings Manufacturer, Supplier, and Exporter in India
Introduction
Stainless Steel 15-5PH pipe fittings are a premium-grade solution for industries requiring a combination of strength, corrosion resistance, and toughness. As a precipitation-hardening stainless steel, 15-5PH offers a unique balance of properties that make it ideal for aerospace, marine, petrochemical, and nuclear applications.
At Mcneil Instruments, we are proud to be a leading manufacturer, supplier, and exporter of 15-5PH stainless steel pipe fittings in India, offering unmatched quality, technical compliance, and global delivery across sectors.
What is 15-5PH Stainless Steel?
15-5PH (UNS S15500) is a martensitic, precipitation-hardening stainless steel. It is derived from the more common 17-4PH stainless steel, but with improved toughness, weldability, and superior transverse properties. Thanks to its low carbon content and balanced chemistry, 15-5PH delivers:
- Excellent corrosion resistance in marine and chemical environments.
- High strength with exceptional mechanical properties up to 600°F (316°C).
- Good machinability and weldability, even in the hardened condition.
- Low distortion during heat treatment, making it ideal for precision fittings.

Why Choose 15-5PH Over 17-4PH?
While both 15-5PH and 17-4PH are PH stainless steels, 15-5PH is preferred where:
- Higher transverse toughness is critical.
- Better weldability and formability is required.
- Superior metallurgical consistency and minimized delta ferrite are needed.
