1.4539 stainless steel, also known as 317LN, is an excellent choice for structural H-sections in a variety of industrial applications requiring good corrosion resistance, mechanical strength and thermal stability. Here are the main advantages of using 1.4539 stainless steel for H-shaped structural steel:

1.4539 stainless steel contains 18-20% chromium, 11-14% nickel and 3-4% molybdenum, providing excellent resistance to pitting, crevice and stress corrosion cracking.
This corrosion resistance makes 1.4539 Structural H-profiles suitable for use in environments exposed to a wide range of acids, chlorides and other corrosive media, such as the chemical processing, petrochemical and marine industries.

1.4539 stainless steel has good resistance to a wide range of chemicals, including organic and inorganic acids and various alkaline solutions.
The high molybdenum content in the alloy increases its resistance to localized corrosion, making the 1.4539 Structure H-profile suitable for chemical processing, pharmaceutical and food processing applications.

1.4539 stainless steel maintains its mechanical properties and corrosion resistance at temperatures ranging from low temperatures to high temperatures up to 600°C (1112°F).
This thermal stability is particularly beneficial for applications involving temperature fluctuations or exposure to high temperatures, such as in heat exchangers or high-temperature chemical processes.

1.4539 stainless steel can be easily welded using a variety of techniques, including TIG, MIG, and plasma arc welding.
The material’s high ductility and formability make it easy to manufacture, including bending, rolling and machining, to produce a variety of structural H-profiles with different sizes and cross-sectional shapes.
This manufacturing flexibility enables the design and construction of complex structures and parts using 1.4539 stainless steel.

1.4539 stainless steel has good mechanical strength, with typical tensile strength of 520 to 680 MPa and yield strength of 240 to 400 MPa.
The material’s ductility and toughness make 1.4539 Structural H-profiles suitable for applications where high mechanical loads and impact forces are expected, such as load-bearing structures, equipment frames and industrial facilities.

The smooth, non-porous surface of 1.4539 stainless steel, combined with its excellent corrosion resistance, makes it easy to clean and maintain a high level of hygiene.
This property is particularly important in food processing, pharmaceuticals and other industries where cleanliness and hygiene are critical.

While 1.4539 stainless steel may not offer the same level of corrosion resistance as UNS N08904 (904L) in the harshest environments, it still offers excellent performance and is a widely used material for structural H-sections in a variety of industrial applications , especially where good corrosion resistance, mechanical strength and manufacturing flexibility are necessary.
