SS 15-5 PH / 1.4545 Round Bars Suppliers and Exporters

SS 15-5 PH / 1.4545 Round Bars are precipitation-hardening stainless steel bars designed to deliver high strength, good corrosion resistance and reliable mechanical performance. Also known as UNS S15500 Stainless Steel, EN 1.4545 Stainless Steel and AISI XM-12, this chromium-nickel-copper alloy develops its final mechanical properties through controlled ageing heat treatment.

SS 15-5 PH Round Bar Overview

Compared with conventional stainless steel grades, SS 15-5 PH Stainless Steel is particularly useful for precision-engineered components that require a combination of strength, toughness and dimensional stability. Its composition and metallurgical structure can provide improved transverse toughness compared with 17-4 PH in suitable product conditions.

Mehta Metal Industries welcomes enquiries for SS 15-5 PH / 1.4545 Round Bars in specified diameters, lengths, finishes and heat-treatment conditions, subject to availability and order requirements.

Frequently Asked Questions

  • 1. What is SS 15-5 PH stainless steel?
    SS 15-5 PH is a martensitic precipitation-hardening stainless steel containing chromium, nickel and copper, with niobium used as a stabilising and hardening addition. Controlled ageing increases its strength and hardness.
  • 2. Is 15-5 PH the same as UNS S15500 and 1.4545?
    UNS S15500 and material number 1.4545 are commonly associated with 15-5 PH stainless steel. The EN designation is X5CrNiCu15-5, and XM-12 is a designation used in relevant ASTM specifications. Confirm the governing standard before substituting material.
  • 3. What is the difference between 15-5 PH and 17-4 PH?
    Both are precipitation-hardening stainless steels with broadly similar strengthening mechanisms. Their chromium and nickel ranges differ, and 15-5 PH is designed to reduce delta ferrite and improve transverse toughness in suitable product conditions. The best choice depends on the component, loading direction, specification and required heat treatment.
  • 4. What heat-treatment conditions are available for 15-5 PH round bars?
    Common ageing conditions include H900, H1025 and H1150. Each produces a different balance of strength, hardness and toughness. The required condition should be specified according to the component design and applicable standard.
  • 5. What are the main applications of 15-5 PH round bars?
    Typical applications include aerospace components, pump and valve parts, oil and gas equipment, industrial machinery and precision-engineered components. Suitability depends on service conditions and verified material properties.
  • 6. Does 15-5 PH stainless steel resist corrosion?
    It provides good corrosion resistance in many industrial environments. However, performance depends on the environment, surface condition, heat treatment, temperature and exposure to chlorides or other aggressive chemicals. Confirm suitability for the intended application.
  • 7. Can SS 15-5 PH round bars be supplied with a Material Test Certificate?
    MTC and inspection requirements can be included in the enquiry. Confirm the availability and scope of the documentation for the specific material and order.
