S44094 Y11Cr17 Martensitic Stainless Steel
S44094 Y11Cr17 is a martensitic stainless steel with a higher chromium percentage compared to the other grades (17%), making it a ‘super’ martensitic stainless steel. The higher chromium percentage of this grade provides enhanced corrosion resistance and general durability, making it well-suited for a variety of applications.
This stainless steel offers outstanding strength to weight ratio and is a great choice for a variety of applications such as aircraft jet engines, valves and pumps, as well as medical devices, food and beverage processing components, chemical processing plants, and more. It is also an excellent choice for parts and components with low-cost requirements.
S44094 Y11Cr17 is easy to machine and weld, providing excellent fabrication and working characteristics. It is also resistant to most organic and inorganic chemicals, making it an ideal choice for acidic environments. It has a high melting point and good hot strength, allowing for better thermal properties when compared to other materials.
S44094 Y11Cr17 is most commonly supplied in the form of cold-rolled sheets and strips, hot rolled sheets and strips, bars and forgings, as well as castings. As a ‘super’ martensitic stainless steel, this grade is used in a wide range of applications in the petrochemical engineering, aerospace and chemical processing industries.
It is typically used in heat exchanger tubes and components, heaters and vessels, parts in demanding chemical and pressure containment systems, as well as valve bodies and fasteners. This grade of stainless steel is also used in vacuum and cryogenic systems, due to its excellent formability, weldability and creep strength.
S44094 Y11Cr17 has a maximum chromium content of 17%, making it one of the highest chromium containing stainless steels on the market. This allows for increased corrosion resistance for various aggressive media, and improved performance in corrosive environments.
This grade of stainless steel is also characterized by increased ageing resistance, allowing for less frequent thermal treatments of components and parts manufactured with this material. It is also particularly resistant to pitting and stress-corrosion, with excellent resistance to cracking.
S44094 Y11Cr17 features a number of additional benefits, making it a great choice for a range of applications. It has good formability and surface finish, with excellent strength and surface hardness. This stainless steel also has excellent tensile, compressive, fatigue and impact strength.
Overall, S44094 Y11Cr17 is an excellent choice for a wide range of general-purpose applications. It is highly robust and cost effective, making it perfect for low cost requirements in a variety of industrial and engineering applications. As such, it is the ideal choice for components and parts exposed to high temperatures, corrosive chemicals and other media, and is well-suited for applications in the aerospace, petrochemical and chemical industries.
