Frequently Asked Questions

  • 1. What is SS 420 / 1.4021 stainless steel?
    SS 420 is a hardenable martensitic stainless steel containing chromium. EN 1.4021, designated X20Cr13, is a commonly associated grade used for applications requiring hardness, strength and moderate corrosion resistance.
  • 2. Is AISI 420 the same as UNS S42000?
    AISI 420 is commonly identified by UNS S42000. However, different 420 variants and product standards can have different chemical composition limits. Confirm the exact material specification before purchasing.
  • 3. Is DIN 1.4021 Steel equivalent to AISI 420?
    EN material number 1.4021 and designation X20Cr13 are commonly cross-referenced with AISI 420. This is a nearest-equivalent relationship rather than a guarantee that all requirements are identical. Verify chemistry and mechanical properties against the governing standard.
  • 4. Can SS 420 round bars be hardened?
    Yes. SS 420 can be hardened through suitable heat treatment, typically involving hardening and tempering. The achievable properties depend on carbon content, processing and the required final condition.
  • 5. What is the corrosion resistance of SS 420 Stainless Steel?
    SS 420 offers moderate corrosion resistance in suitable environments. Its corrosion performance depends on surface finish, heat treatment and exposure conditions. It is generally less resistant to aggressive chloride environments than many common austenitic stainless steel grades.
  • 6. What are the main applications of SS 420 round bars?
    Typical applications include cutlery, blades, pump and valve components, shafts, industrial machinery and selected automotive parts. Suitability depends on the required hardness, mechanical loading and service environment.
  • 7. Can I request a Material Test Certificate?
    Yes, MTC requirements can be included in the enquiry. Confirm the availability and scope of documentation for the specific material and order.
  • 8. How can I get a quotation for SS 420 / 1.4021 Round Bars?
    Provide the required grade, diameter, length, quantity, heat-treatment condition, applicable standard and delivery destination to Mehta Metal Industries. Pricing and delivery details are confirmed subject to availability and order requirements.
