Stainless Steel 321H Pipe Manufacturer | Stainless Steel 321H Pipe Supplier | Stainless Steel 321H Pipe Exporters.

321H is an alloy stabilized with the help of titanium. The Stainless Steel 321H Pipe/ Tube is 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 Pipe is the higher carbon version of the 321 alloy. These pipes have a carbon concentration of 0.04-0.10. This allows it to possess increased creep resistance and strength.321H Stainless Steel Tube have 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 Tubing is widely used in petroleum refineries, boiler tubes, high-pressure steam pipes, heavy-duty exhausts, manifolds, etc. We are the leading supplier of the Stainless Steel 321H Pipe/ Tube in India. We aim to produce the best in the market products at the most reasonable rates.

MK Seamless 321 Stainless Steel Pipes, Size: 1/2-10 inch Dia at Rs  240/kilogram in Mumbai


The 321H pipes and can be manufactured seamlessly or welding procedures. The SS 321H Seamless Pipe is 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 Pipe doesn’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 Pipe is produced through fusion welding procedures. These pipes can be elongated by 40% and still have excellent performance and strength. The AISI 321H Schedule 40 Pipe is 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 Pipe along with our other products can be customized in different shapes and sizes as per your requirements.
The DIN 1.4878 Stainless Steel Round Pipe is a standard pipe used throughout this grade. These pipes are mainly used in supplying fluids and gases from place to place. The SA 312 TP 321H Square Pipe cannot be hardened by hot-rolling them like most other products in these grades. These pipes are used in providing support and maintaining structural integrity. The ASTM A312 Gr.TP 321H Rectangular Pipe is known for its use in aerospace and storage capabilities due to the strength and hardness its possess. If you have any queries or want to know more about our ASTM A312 TP 321Hcontact us for more information.
