Virami Steel Hub is a leading manufacturer, supplier, stockist, and exporter of premium quality Stainless Steel 15-5PH Round Bars in Mumbai, India. We supply SS 15-5PH round bars across India and export globally to the USA, Canada, Europe, Russia, Middle East, Australia, and Southeast Asia. Our materials are manufactured as per international quality standards and undergo stringent inspection procedures to ensure superior strength, corrosion resistance, and dimensional accuracy.
Stainless Steel 15-5PH Round Bars are widely used in aerospace, petrochemical, nuclear, marine, defense, and high-pressure industrial applications due to their excellent combination of high strength, toughness, and corrosion resistance.
Stainless Steel 15-5PH (UNS S15500) is a martensitic precipitation-hardening stainless steel. It is an improved version of 17-4PH stainless steel with enhanced toughness and transverse mechanical properties. The alloy achieves high strength through a heat treatment process known as precipitation hardening (aging).
The name 15-5PH represents:
SS 15-5PH Round Bars are solid cylindrical bars used for machining high-strength components such as shafts, fasteners, valve parts, and structural aerospace components.
Role of Major Alloying Elements
Mechanical properties vary depending on aging condition (H900, H1025, H1075, H1150).
Typical Mechanical Properties (H900 Condition - Maximum Strength)
Typical Mechanical Properties (H1150 Condition - Improved Toughness)
One of the key advantages of 15-5PH is its precipitation hardening capability.
Step 1: Solution Annealing
Step 2: Aging (Precipitation Hardening)
Aging temperatures include:
SS 15-5PH offers:
Although not as corrosion resistant as 316 stainless steel, it performs very well in aerospace and industrial environments.
Machinability is good in solution-treated condition and becomes more difficult after aging.
Machining Recommendations:
Precipitation hardening should be performed after machining for best dimensional control.
SS 15-5PH can be welded using:
Welding is typically performed in solution-treated condition. Post-weld aging is recommended to restore mechanical properties.
