Special alloy material that is corrosion resistant, heat resistant, and abrasion resistant

Special alloy material that is corrosion resistant, heat resistant, and abrasion resistant

Features

These are nickel-based corrosion-resistant alloys.
We handle materials that provide excellent corrosion resistance in harsh environments that stainless materials cannot withstand.

Applications

  • Tower tanks
  • Heat exchangers
  • Centrifuges
  • Driers
  • Pipes (seamless pipes and pipes)
  • Couplers
  • Bolts
  • Nuts
  • Evaporators for salt production
  • Flue-gas desulfurization equipment
  • Semiconductor manufacturing equipment

FAQ

Can you provide estimates, including processing?
Yes, we can. We can create an estimate based on your technical drawings.
(See the page (7) Finished products from specialty alloys (devices, machinery, and parts))
Can you provide advice on selecting materials?
Yes, we can.
Do have an inventory of sheets and bars?
We always keep sheets and bars in stock. Please contact us for details.
Do you cut materials?
We can cut even one bar or sheet from our inventory.
Do you sell by the piece?
We sell by the piece from our inventory.
Is it possible to specify the outer diameter and wall thickness?
Yes.
Do you handle small pipes?
It depends on the material, but we handle pipes as small as 1.59 in diameter.
