Stainless Steel 420 is a martensitic stainless steel, typically composed of 12–14% chromium and 0.15% carbon, along with trace elements of manganese, silicon, and nickel. This blend results in high hardness, excellent wear resistance, and decent corrosion resistance when properly heat-treated. Its mechanical properties boast tensile strength between 580–800 MPa and hardness levels reaching up to 50 HRC, depending on the heat treatment process. Its ease of machining and hardening makes it perfect for precision components that demand strength, toughness, and abrasion resistance.
With outstanding corrosion resistance, Stainless Steel 904L Seamless Tubing is ideal for high-pressure applications. Typically available in sizes ranging from 1/8″ to 8″ in diameter and custom lengths, it offers uniform strength and durability without weld seams.
Welded stainless steel tubing provides good corrosion resistance and is often used in less critical applications. Sizes generally range from 1/2″ to 12″ in diameter. Its manufacturing process involves welding a flat-rolled stainless steel sheet into a tube shape.
Stainless steel heat exchanger tubes are highly corrosion-resistant and designed for thermal conductivity. Available in various sizes, typically from 1/2″ to 4″ in diameter and up to 20 feet long. Essential for efficient heat transfer in industrial processes.
Instrumentation stainless steel tubing offers excellent corrosion resistance and is used for precise control systems. Standard sizes range from 1/16″ to 1″ in diameter. It ensures reliable performance in various high-pressure and high-temperature applications.
Boiler tubes of stainless steel are known for their exceptional corrosion and high-temperature resistance. Available in sizes from 1/2″ to 4″ in diameter. Designed for use in power generation and industrial boilers to handle high-pressure steam.
Stainless steel U-tubes provide high corrosion resistance and are used in heat exchangers and condensers. Sizes usually range from 1/2″ to 4″ in diameter. They are fabricated into a U shape to fit specific thermal or fluid flow requirements.
Condenser tubes made of stainless steel are highly corrosion-resistant and used in cooling systems. Commonly available in diameters from 1/2″ to 4″ and lengths up to 20 feet. Essential for efficient heat exchange in cooling applications.
Stainless steel fin tubes offer enhanced heat transfer efficiency and corrosion resistance. Sizes range from 1/2″ to 4″ in diameter with various fin heights and thicknesses. They are used in applications with critical heat exchange efficiency, such as HVAC systems.
