Frequently Asked Questions

  • 1. What is SS 17-4 PH stainless steel?
    SS 17-4 PH is a martensitic precipitation-hardening stainless steel that combines high strength with useful corrosion resistance. Its properties can be adjusted through suitable ageing heat treatments.
  • 2. Is 1.4542 the same as UNS S17400?
    Yes. Material number 1.4542 and UNS S17400 are widely used designations for 17-4 PH stainless steel. The designation AISI 630 is also commonly associated with this alloy. Always verify the applicable product standard and specification.
  • 3. What is the difference between 17-4 PH and ordinary stainless steel?
    Unlike common austenitic grades such as 304 or 316, 17-4 PH can be strengthened through precipitation hardening. It is often selected where higher strength is needed alongside corrosion resistance, although its corrosion performance depends on the environment and heat-treatment condition.
  • 4. What heat-treatment conditions are available for 17-4 PH round bars?
    17-4 PH can be supplied in a solution-treated condition or precipitation-hardened conditions such as H900 and H1150, depending on the product specification and supply capability. These conditions provide different combinations of strength, hardness and toughness.
  • 5. Are 17-4 PH round bars corrosion-resistant?
    They offer useful corrosion resistance in many industrial environments. However, resistance is not universal; chloride exposure, temperature, stress, surface condition and heat treatment can affect performance. The alloy should be assessed for the actual service environment.
  • 6. Which industries use SS 17-4 PH round bars?
    Typical applications include aerospace, oil and gas, pump and valve manufacturing, chemical processing, marine engineering and general machinery. Suitability depends on the component design and specified material condition.
  • 7. Can I request a Material Test Certificate?
    MTC and inspection-documentation requirements can be included in your enquiry. Confirm the availability and scope of the documentation before placing the order.
  • 8. How can I request a quote for SS 17-4 PH / 1.4542 Round Bars?
    Provide the required diameter, length, quantity, heat-treatment condition, applicable standard, documentation needs and delivery destination to Mehta Metal Industries. Pricing and delivery are confirmed subject to specification and availability.
