17-7 ph stainless steel rod, AMS 5644 Steel 17-7 PH Hex Bar, UNS S17700 Flat bar Suppliers in China.
Stainless Steel 17-7 Bright /Square and Cold Finished Bars Manufacturers.
17-7 Ph Stainless Steel Round Bar is made up of a chromium, nickel aluminum alloy. High Temperature Fasteners Inc. is a leading manufacturer and supplier of the different types of bars from this material grade. The material has carbon, phosphorus, silicon, iron, manganese, sulfur, 17% chromium, 7% nickel and 0.75% aluminum in the composition. The 17-7 Ph Stainless Steel Rod has 1170MPa minimum tensile strength and 965MPa minimum yield strength.
These are very high values compared to ordinary austenitic stainless steels. Due to these high mechanical values, the AMS 5644 Steel 17-7 PH Hex Bar and other types are used in aerospace, chemical processing equipment, oil and gas, petroleum refinery, food grade stainless steel equipment and in other general metalworking applications as well. The dimensions of the bars are covered by EN, DIN, ASTM, AISI, ASME and other international standards.
The UNS S17700 Flat Bar can come in different finishes like black, bright polished and so on with the surface treated with hot rolled pickled, sand blasting finished, cold drawn, bright and so on. The Stainless Steel 17-7 Square Bars are also used in the similar capacity but with having much more strength due to the shape. As a leading supplier and manufacturer, we produce and supply the bars in all different types. Please feel free to contact us for more information and pricing.
