Properties of 347 Stainless Steel Bars
347 Stainless Steel Bars Have Good Strength and Toughness
One of the most important mechanical properties of 347 stainless steel bars is their strength and toughness. This means they can withstand much force without breaking or bending. They are also resistant to wear and tear, making them ideal for use in high-stress environments.
347 Stainless Steel Bars Have Good Corrosion Resistance
Another important mechanical property of 347 stainless steel bars is their corrosion resistance. This means that they will not rust or corrode when exposed to moisture or other corrosive materials. They also resist staining and discoloration, making them ideal for food processing and medical applications.
347 Stainless Steel Bars Have Good Weldability
Another important mechanical property of 347 ss bars is good weldability. This means they can be easily welded to other metals without cracking or breaking. They are also resistant to heat, making them ideal for use in high-temperature applications.
347 Stainless Steel Bar Have Good Machinability
Another important mechanical property of 347 stainless steel bars is their good machinability. This means they can be easily cut, drilled, and machined without cracking or breaking. They are also resistant to heat, making them ideal for use in high-temperature applications.
347 Stainless Steel Bar Have Good Formability
Another important mechanical property of the stainless steel 347 bar is its good formability. This means they can be easily formed into shapes without cracking or breaking. They are also resistant to heat, making them ideal for use in high-temperature applications.
Composition:
347 stainless steel is an austenitic stainless steel, which means that it is a non-magnetic iron-based alloy that is highly resistant to corrosion and has a high level of toughness and ductility. Like other austenitic stainless steels, 347 contains high levels of chromium and nickel, which give it its corrosion resistance. It also contains small amounts of tantalum and columbium, which work to stabilize the steel and protect it from intergranular corrosion. The addition of these elements also helps to improve the strength and hardness of the alloy.
Applications:
347 stainless steel is used in various applications, including aerospace, automotive, and chemical processing industries. Its high-temperature resistance makes it ideal for use in jet engine parts, where it is used to create turbine blades, casings, and combustion chambers. It is also used in the production of chemical processing equipment, where it is used for pipes, valves, reactors, and heat exchangers. Other applications for 347 stainless steel include food and pharmaceutical processing and constructing chemical plants, oil refineries, and power plants.
Processing and Heat Treatment:
347 stainless steel can be easily formed by cold working and hot working and can be welded using various techniques, including gas tungsten arc welding, gas metal arc welding, and shielded metal arc welding. Heat-treated 347 stainless steel can help to improve its strength and hardness and to remove residual stresses in the metal. The alloy is heat-treated at temperatures between 1950 and 2150°F (1065 and 1175°C), followed by water quenching. This process helps to improve the alloy’s mechanical properties and ensure that it retains its excellent corrosion resistance.
Conclusion:
347 stainless steel is a versatile and highly useful alloy that is used in a wide variety of applications. Its excellent high-temperature resistance, corrosion resistance, and toughness make it an ideal material for use in the aerospace, automotive, and chemical processing industries. If you need a strong and reliable material for your next project, consider using 347 stainless steel bars. With their superior properties and excellent composition, they can help you to create a finished product that will stand the test of time.
