ASTM A312 TP321H Stainless Steel Pipe

ASME SA 312 321H ERW Pipe & SS 321H Seamless Pipe manufacturer in India

ASTM A312 Tp321h is a high carbon version of the titanium stabilized austenitic stainless steel. It has 18% chromium and 8% nickel in the common composition and therefore is called as the 18/8 steel as well. Oshwin Overseas is a manufacturer and supplier of the ASTM A312 Gr.Tp321h pipe types in all kinds, scales and dimensions. There are different production methods such as electric fusion welding, electric resistant welding, cold drawing or hot rolling of the ASTM A312 Tp 321h pipes. The titanium addition in the SA312 Tp321h material composition makes it stronger and more corrosion resistant. It also provides the material last longing life under even corrosive environments. The higher carbon content makes it tougher, but it can compromise the strength compared to the low carbon versions. Due to the increased toughness, it can perform well under cryogenic temperatures as well.

Our A312 Tp 321h products are of superior quality and are tested to the international standards. Our products are used in laboratory equipment, architectural applications in marine environments, food processing industry, and in some chemical processing industries as well. The 321h Stainless Steel Pipe is seamless and has less absolute roughness. The SS 321h Erw Pipe of this type are used for extra strength and ease of welding. However, the SS 321h Welded Pipe has higher carbide precipitation rate than the low carbon material. Regardless of this fact, it is used in applications because of the toughness. You can contact us for further product details and pricing.

Know more about testing requirements for 321h pipe for petrochemical industry

The 321H material has titanium as a stabilizing agent along with nickel, chromium, manganese, silicon and other elements in the composition. The material is meant to be highly corrosion resistant, oxidation resistant and heat resistant. It is used in applications such as aircraft exhaust, welding equipment, chemical processing equipment and in jet engine parts.

To make sure that the components are up to the standards, they have to be tested. The intergranular corrosion tests are done with copper-copper sulfate in 16% sulfuric acid. This is to ensure that the material has less intergranular corrosion after welding as it was intended. The corrosion cracking test, the test for elevated temperature corrosion cracking and tensile and yield strength tests are few of them.

Not all materials require all the tests to be performed. Some are optional for manufacture to do only when the customer specifically asks. Some are mandatory for the manufacturer to issue certificates as per the test. The 321H pipes require the EN10204 3.1,3.2 certificates, so the manufacturer has to perform these tests. Also, when third party tests are needed, those tests are performed as well as approved laboratory tests when required.
