Stainless Steel 17-4 PH Round Bar
Neminox steel and engineering co. is a certified manufacturing company that manufactures and supplies steel-grade products. We supply all types of flanges, pipes, weld fittings, fasteners, tubes, bars, etc. We always make sure that all the products are well tested and certified.
These Stainless Steel 17-4 PH round bars are made of austenitic steel with copper, tantalum, and niobium. These round bars are very ductile and strong with great stability. This grade is efficiently machined and formed. The heat tolerance of this grade is up to 1038°C (1900°F). This grade is 100% resistive to corrosion and other chemical fractions caused by erosion, humidity, and heat. Stainless steel 17-4 is also known as martensitic stainless steel. These round bars are non-magnetic, and they are exposed to the temperature of 800°C-1500°F (i.e., 400-816°C) it achieves chromium carbide precipitation.
The chemical composition also includes 3-5% nickel, 3-5% copper and 15-17% chromium. This grade is suitable for the petrochemical and chemical industries. These industries involve high-temperature applications; hence 17-4PH round bars are perfect for it.
- The diameter of round size bars starts from 3mm to 800mm
- The thickness of the flat bar varies from 2mm to 100mm, whereas the width of the bars starts from 10mm to 500mm
