Products Description
17-4 Stainless Steel Square Metal Tubes
What Is 17-4 Stainless Steel Used For?
Oil and Gas
17-4 stainless steel is a good choice for the oil and gas industry because of its ability to withstand harsh conditions and corrosive environments. The alloy is highly resistant to corrosion caused by saltwater and chemicals, making it well suited for use in offshore and coastal environments.
Additionally, 17-4 stainless steel has a high strength-to-weight ratio, which makes it ideal for use in the oil and gas industry where weight and size are often critical factors.
Petrochemical
In the petrochemical industry, 17-4 stainless steel is commonly used in the production of process equipment, such as heat exchangers, pumps, and valves. Additionally, 17-4 stainless steel is used for tanks, reactors, and other vessels that are used to store and transport chemicals and petrochemicals.
The alloy maintains its structural integrity at high temperatures, making it suitable for use in applications like the production of heat exchangers and other equipment that is used in the processing and transportation of petrochemicals.
Aerospace
17-4 stainless steel can be used in the production of aircraft engine components, such as turbine blades and rotors, as well as in the production of aircraft instruments and structural components like landing gear.
The alloy is well-suited for use in aerospace components that are exposed to high loads and harsh environments, such as high altitude and extreme temperatures.
Food Processing
In the food processing industry, corrosion-resistant 17-4 stainless steel is often used in the production of food processing equipment, such as storage tanks, conveyors, and processing machinery. The alloy is magnetic, making it ideal for use in food environments where magnets are used to ensure contaminants are removed.
Additionally, the high strength and durability of 17-4 stainless steel make it well suited for use in applications that require frequent sanitation and cleaning processes.
Paper / Pulp
In the paper and pulp industry, 17-4 stainless steel is used when creating equipment that processes pulp such as tanks, pumps, valves, and heat exchangers. Because the parts may be exposed to high temperatures, it's important to use a resilient alloy like 17-4.

17-4 Stainless Steel Square Metal Tubes
17-4 stainless is an age-hardening martensitic stainless combining high strength with the corrosion resistance of stainless steel. Hardening is achieved by a short-time, simple low-temperature treatment. Unlike conventional martensitic stainless steels, such as type 410, 17-4 is quite weldable. The strength, corrosion resistance and simplified fabrication can make 17-4 stainless a cost-effective replacement for high strength carbon steels as well as other stainless grades.At the solution treating temperature, 1900°F, the metal is austenitic but undergoes transformation to a low-carbon martensitic structure during cooling to room temperature. This transformation is not complete until the temperature drops to 90°F. Subsequent heating to temperatures of 900-1150°F for one to four hours precipitation strengthens the alloy. This hardening treatment also tempers the martensitic structure, increasing ductility and toughness.
