FAQ

  • Q Is 430 stainless steel magnetic?

    A
    Yes, it is fully magnetic in all conditions.

  • Q Why is 430 cheaper than 304?

    A
    Because it does not contain nickel, which  lowers cost but also reduces toughness and  corrosion resistance.

  • Q Can 440C be machined easily?

    A
    It is harder to machine than lower-carbon  steels, but machinability improves in the  annealed condition.

  • Q Is 440C stainless steel corrosion resistant?

    A
    It has moderate corrosion resistance, but less  t han 304 or 316, so it is not suitable for marine  environments.

  • Q Why is 440C used for knives and bearings?

    A
    Because it provides high hardness, wear  resistance, and good edge retention.

  • Q Can 420 stainless steel be mirror-polished?

    A
    Yes, it has excellent polishability and is often  used for high-shine surfaces like cutlery and  medical tools.

  • Q How does 420 compare to 440C?

    A
    420 is tougher but less hard and wear-resistant  t han 440C, making it better for applications  needing durability over extreme hardness.

  • Q Why is 420 called surgical stainless steel?

    A
    Because it is widely used for surgical tools due  to its polishability, hardness, and acceptable  c orrosion resistance.

  • Q Where is A286 commonly used?

    A
    In aerospace engines, gas turbines, and high  t emperature fastening systems.

  • Q Is A286 corrosion resistant?

    A
    Yes, it has corrosion resistance comparable to  316, plus excellent oxidation resistance at high  heat.

  • Q Why is A286 considered a high-temperature alloy?

    A
    Because it retains high strength and stability up  to 700 °C.

  • Q What industries use Nitronic 60 most?

    A
    Oil & gas, marine, and machinery industries that  require anti-galling fasteners and valves.

  • Q Does Nitronic 60 have good corrosion resistance?

    A
    Yes, it is similar to 304/316, but its main  advantage is wear resistance.

  • Q Why is Nitronic 60 special compared to 304/316?

    A
    Because it resists galling and wear far better,  even under heavy sliding contact.

  • Q What surface treatments are available for stainless steel?

    A
    Passivation, bead blasting, polishing, black  oxide, and plating are commonly applied to  improve performance and aesthetics.

  • Q What industries most often request stainless steel parts?

    A
    Aerospace, automotive, medical, food  processing, and consumer goods industries  commonly specify stainless steel for strength  a nd durability.

  • Q Is stainless steel suitable for high-precision parts?

    A
    Yes. With CNC machining, stainless steel  delivers excellent dimensional stability and  wear resistance for complex, high-tolerance  components.

  • Q Which stainless steel grades are typically machined?

    A
    Grades such as 303 and 304 are common for general parts, 316/316L for marine and medical, and 17-4PH for aerospace and highstrength applications.

  • Q Why choose stainless steel instead of carbon steel?

    A
    Stainless steel provides superior corrosion  r esistance and hygiene, making it suitable for  medical, food, and marine applications, whereas  carbon steel requires protective coatings.

  • Q Is C101 easy to machine?

    A
    Yes, but its softness requires sharp tooling and  proper machining parameters to avoid  deformation.
