FAQ

  • Q Can steel parts achieve high dimensional accuracy?

    A
    Yes. With CNC machining and proper heat  treatment, steel maintains excellent precision  and durability

  • Q Which grades of steel are best for CNC machining?

    A
    Mild steel (1018) is ideal for general parts,  m edium carbon steel (1045) for stronger  components, and alloy steels like 4140/4340 for  high-performance applications.

  • Q How does steel compare with stainless steel in performance?

    A
    Steel is more cost-effective and strong but  requires coatings or treatments to prevent  corrosion, unlike stainless steel which has  natural resistance.

  • Q What are the typical applications of 15-5?

    A
    It is commonly used for aerospace components,  marine shafts, valves, gears, and structural  parts requiring high strength and corrosion  resistance.

  • Q How does 15-5 compare to 17-4 PH?

    A
    15-5 offers better toughness and weldability  t han 17-4 PH, while maintaining similar strength  levels.

  • Q What is Stainless Steel 15-5 used for?

    A
    It is widely used in aerospace, marine, and  chemical equipment due to its combination of  strength, toughness, and corrosion resistance.

  • Q What are the typical applications of 17-4 PH?

    A
    It is commonly used for shafts, gears, turbine  blades, fittings, and structural components in  aerospace and marine equipment.

  • Q How does 17-4 PH compare to 15-5?

    A
    17-4 PH provides excellent strength and  corrosion resistance, while 15-5 offers slightly  better toughness and weldability.

  • Q What is Stainless Steel 17-4 PH used for?

    A
    It is widely applied in aerospace, marine,  nuclear, and chemical industries for its strength  and corrosion resistance.

  • Q Can Duplex 2205 be welded easily?

    A
    Yes, it has good weldability, but heat input must  be controlled to maintain the duplex structure.

  • Q Is 2205 suitable for seawater?

    A
    Yes, it resists seawater corrosion better than  316L.

  • Q Why use Duplex 2205 instead of 316?

    A
    Because 2205 offers higher strength and better  resistance to chloride stress corrosion cracking.

  • Q Does 301 become magnetic after forming?

    A
    Yes, cold working induces martensite, making it  partially magnetic.

  • Q Can 301 be used in cryogenic conditions?

    A
    Yes, it maintains toughness at very low  t emperatures.

  • Q How does 301 compare to 304?

    A
    301 has higher strength but slightly lower  corrosion resistance.

  • Q Does the sulfur in 303 affect corrosion resistance?

    A
    Yes, sulfur improves machinability but reduces  corrosion resistance compared to 304.

  • Q Is 303 suitable for marine use?

    A
    No, its corrosion resistance is lower than  304/316 and not recommended for marine  environments.

  • Q Why choose 303 instead of 304?

    A
    303 is easier to machine, saving time and cost in  CNC processing.

  • Q Is 321 stainless steel magnetic?

    A
    In the annealed state, 321 is non-magnetic, but  slight magnetism may appear after cold  working.

  • Q What is the maximum service temperature for 321?

    A
    It is generally used up to 870 °C (1600 °F) for  oxidation resistance, and up to 925 °C (1700 °F)  for intermittent service.
