This stainless steel tube comes in either welded or seamless forms. Welded pipes are formed by welding larger pieces of metal together, while seamless pipes are produced through a hot rolling process that creates one piece without seams or joints. Ultimately, the type of pipe you require depends on your application; be sure to review material specifications prior to ordering.
This alloy contains 22-24% chromium and 12-15% nickel with up to 0.08% carbon, as well as traces of other elements like molybdenum, silicon, phosphorus and sulfur.
Its high corrosion resistance and formability/ductility make it ideal for fabrication projects. Plus, its high chromium and nickel content gives it superior strength at temperatures up to 2000 degree Fahrenheit.
Contrary to 304, this alloy contains more nickel which increases its resistance to sulfate and sulphide attack. As such, it is frequently employed in furnaces, incinerators, catalytic recovery systems and rotary kilns.
This austenitic chromium-nickel stainless steel is highly heat resistant and can be joined using either resistance or fusion welding techniques. Furthermore, it may be annealed after cold working to increase its strength.
Machine and fabricate this metal according to standard shop fabrication practices. It can be headed, upset, drawn and stamped for added strength while cold working can increase tensile and yield strengths.
Alloy 309 ss has a low carbon content, which helps minimize carbide precipitation during welding. This can reduce weld spatter and enhance weldability.
This alloy can withstand temperatures up to 1900 degrees Fahrenheit without cycling and may slightly decrease with frequent thermal cycling. Furthermore, its high chromium and alloying elements further contribute to its strength.
It is an ideal material for applications such as incinerators, furnaces, burners, kilns, annealing and carburizing boxes, combustion chambers, salt pots and thermo wells. Furthermore, it has found use in petroleum refining facilities where high heat resistance is necessary.
Due to its superior corrosion resistance, this material is an ideal substitute for 304 steel in piping and vessels. It boasts higher tensile and shear strengths than the stainless steel equivalent, making it more durable overall.
This stainless steel is capable of being formed into various components such as rods, bars, plates and sheets forgings pipe fittings and flanges. Additionally, it can be cut into shaped pieces that can be machined or drilled according to your project requirements.
This stainless steel tubing boasts an incredible tensile strength, making it the ideal material for structural piping systems and supports that will last years to come. Being more resistant to rust than carbon steel and aluminum, stainless steel tubing makes a great choice for applications requiring long-lasting durability – especially when installed in corrosive environments.
