321H is an alloy stabilized with the help of titanium. The Stainless Steel 321H Pipe/ Tubeis an austenitic steel, which is designed to work at carbide precipitation temperatures, which the other grades can't work. In this grade pipes, and tubes can work at temperatures ranging from 800-1500 degrees F. The Stainless Steel 321H Pipeis the higher carbon version of the 321 alloy.
These pipes have a carbon concentration of 0.04-0.10. This allows it to posses increased creep resistance and strength.321H Stainless Steel Tubehave an outer diameter of 6mm-250mm and its thickness ranges from 0.3mm-50mm. These tubes are available in a variety of grades. The Stainless Steel 1.4878 Tubingis widely used in petroleum refineries, boiler tubes, high-pressure steam pipes, heavy-duty exhausts, manifolds, etc.
The 321H pipes and can be manufactured seamlessly or welding procedures. The SS 321H Seamless Pipeis produced from a single piece of steel. These pipes have a tensile strength of above 515Mpa and yield strength of above 205Mpa. The 321H SS Welded Pipedoesn't suffer from post weld carburization or corrosion in this grade. These welded pipes are strong, durable and don't require high maintenance. The UNS S32109 ERW Pipeis produced through fusion welding procedures.
These pipes can be elongated by 40% and still have excellent performance and strength. The AISI 321H Schedule 40 Pipeis very ductile and has excellent low temperature toughness. These pipes can be easily welded through most standard welding processes. The SS grade 1.4878 Polished Pipeis produced after cold-rolling this pipes. These polished pipes are smooth which gives it added protection against corrosion and other corrosive mediums. The 321H Stainless Steel Pipealong with our other products can be customized in different shapes and sizes as per your requirements.
