The 446 alloy belongs to a ferritic stainless steel grade. A 446 Stainless Steel Pipe is produced with a chemical composition of iron, chromium, manganese, silicon, nickel carbon, phosphorous, and sulfur. The content allows these pipes to have enhanced corrosion and oxidation resistant properties. The Stainless Steel 446 Pipe is a high-strength component that has low alloys embedded in them. These pipes showcase an excellent density of 7.80 g/cm3 in the system. Stainless Steel 446 Tube exhibits superior mechanical properties. These tubes have a minimum tensile strength of 550mpa with a minimum yield strength of 345mpa. These tubes have an elongation at a break of 20% with a hardness of Brinell 159. Designed with a thermal conductivity of 21.6 W/mK, the A312 GR TP446 Tubing can be customized in different shapes and sizes as per customer requirements.
The pipes in the 416 SS grade can be designed in seamless, welded, and erw configurations. Stainless Steel 446 Seamless Pipe is made up of a single metal grade without any filler or welded part. These pipes showcase enhanced strength and outstanding load-bearing capacity in comparison to other pipes in this range. The Stainless Steel 446 Welded Pipe, on the contrary, has welds or seams as sheets or strips are welded using standard welding procedures. These pipes offer a cost-effective solution to seamless pipe grades. A Stainless Steel 446 ERW Pipe is manufactured as metal is rolled and welded longitudinally using a high voltage current. For the welding process to take place efficiently these pipes don’t require any filler material. The versatile AISI 446 Round Pipe is a common feature in boiler baffles, annealing boxes, industrial mufflers, glass molds, furnace parts, kiln linings, oil burnet components, X-ray tubes, etc. To know more about our products or their price point, contact us for more.
