Jay Hind Metal & Tubes supply a wide range of Stainless Steel 321 / 321H Seamless U Tubes to our clients which are sturdy in construction and ensure long life. We supply products to national and international customer’s at most reasonable rates. The production of SS tubes is made from reliable raw materials. These tubes are formed in the hollow shaped under latest machines. Seamless tubes are mainly utilized in various engineering and industrial sectors.
General corrosion resistance:
Alloy 321/ 321H offer similar resistance to general and local corrosion same as conventional grades. This alloy also resists moderate and aggressive organic acids. It has good resistance to atmospheric corrosion. It has higher chromium content that provides resistance to oxidizing solutions such as nitric acids. These tubes perform well in fresh water with low and high levels of chlorides.
In higher chloride levels it is susceptible to crevice and pitting corrosion cracking. It is prone to stress corrosion cracking even in high temperatures. It has sufficient resistance to intergranular attacks (IGA).
These tubes are formed with both hot and cold forming process. These are annealed or hot worked to acquire higher mechanical attributes. These are weldable too.
We consistently provide the highest quality products and services. We ensure our raw materials are of the highest quality. The training teams on standard procedures and documents implement thorough quality control in all production process. Those tests are tensile test, positive material test, micro/ macro test, hardness test, destructive/non-destructive test, chemical analysis, proof load test, fatigue test, and flexure test. Secondary tests are compression test, torsion test, creep test, drop weight test, mechanical test, IGC test, flaring test, radiographic test, pitting corrosion test, and ultrasonic test.
Lastly, third party inspection is performed to ensure final quality.
These are delivered in the form of bundles or placed in wooden cases, cartons, boxes, and pallets with plastic end cap support. The packaging can be customized as per the convenience of customers.
Stainless Steel 321 / 321H Seamless U Tubes are available in different finishes and treatments, one can place online orders.
