Alloy 20 Forged Fittings
Arrow Piping Solutions is one of the leading manufacturers, suppliers, distributors, and exporters of Alloy 20 products. We offer a wide range of forged fittings made from Alloy 20 that are widely appreciated for their strength, corrosion resistance, and suitability for harsh industrial environments.
Alloy 20, also known as Carpenter 20 or Alloy 20Cb-3®, is an austenitic stainless steel developed primarily for applications involving sulfuric acid. This alloy offers excellent resistance to corrosion, pitting, and stress-corrosion cracking. With the inclusion of elements like nickel, chromium, molybdenum, and copper, Alloy 20 performs well in both hot and cold working conditions, making it ideal for various industries.

We are maintaining our quality standards higher, and for this, we have our own set of procedures. We check and verify quality as well as the performance of Fittings in the whole manufacturing process, which helps to avoid defects. We perform different tests at various stages of production which ensure accuracy of Fittings. We also perform tests to check the authenticity of alloy 20 before use it in Fitting manufacturing. To check other standards, we test Alloy 20 Forged Fittings with flattening test, hardness test, and other non-destructive tests. Along with quality testing, we are also taking care of convenient doorstep service at affordable rates and by following deadlines.
