MERIH STAINLESS is an established manufacturer and distributor in Istanbul, Turkey, focusing on high-performance stainless steel fasteners like Stainless Steel 422 Stud Bolts. As a company whose reputation is founded upon precision engineering and consistent quality, MERIH STAINLESS supplies a diverse range of industries including aerospace, power generation, and petrochemical processing. Their dedication to providing robust, heat-resistant, corrosion-tolerant fastening products has earned them a choice partner locally and globally. Through incorporating cutting-edge manufacturing technology with robust quality control processes, MERIH STAINLESS ensures that its products comply with high global standards and stringent industrial demands.
Stainless Steel 422 Stud Bolts are produced from a hardenability martensitic stainless steel alloy with about 0.2–0.25% carbon, 11–13% chromium, 0.8–1.0% molybdenum, and trace amounts of tungsten, vanadium, and nickel. This special composition gives a combination of high strength, oxidation resistance, and superior creep resistance at high temperatures. The alloy may be heat treated to attain tensile strengths of 895–1035 MPa and yield strengths of 620–895 MPa. The alloy also possesses toughness and hardness at elevated temperatures with a Rockwell hardness of up to 45 HRC depending on the heat treatment condition.

Stainless Steel 422 Stud Bolts find extensive applications in high-temperature strength and corrosion-resistant applications. Examples include steam and gas turbines, aerospace engine parts, power generation equipment, and high-pressure vessels. Since they can retain mechanical properties under high thermal stress, they are well suited for thermal cycling or long-duration high-heat environments. Additionally, their moderate corrosion resistance makes them suitable for use in oxidizing environments, for example, in combustion systems. Because of these characteristics, 422 stud bolts are also commonly selected for mechanical and structural joints where durability and heat resistance are required.
