Kiah Metallurgical is a renowned manufacturer, supplier and exporter of SS 904L Nuts, which cannot be hardened by heat treatment. Stainless Steel 904L Hex Head Nuts is used in acid processing equipment,  condenser tubes, gas washing, etc. Stainless Steel 904L Square Nuts is fully austenitic and is less sensitive to precipitation of ferrite and sigma phases than conventional austenitic grades with high molybdenum content. Stainless Steel 904L Lock Nuts are often used for Hydrometallurgy and Food and beverage. Stainless Steel 904L Eye Nuts is also used for heat exchangers, acid production and pickling equipment. Stainless Steel 904L Wing Nuts is extremely resistant to heat up to 400 degrees Celsius. A higher resistance to pitting and crevice corrosion in Stainless Steel 904L T-Nuts is required. The high resistance of Stainless Steel 904L Panel Nuts against stress corrosion cracking is due to the presence of high amounts of nickel in its composition.



Stainless Steel 904L Nuts

Although primarily developed for its resistance to sulphuric acid, Stainless Steel 904L Coupling Nuts also has a very high resistance to a wide range of environments. These Stainless Steel 904L Dome Nuts have applications in piping systems, pollution control equipment, heat exchanges, and bleaching systems. Stainless Steel 904L Acorn Nuts also offer good resistance to other inorganic acids such as hot phosphoric acid as well as most organic acids. For maximum corrosion resistance, these 904L Stainless Steel Nuts are recommended to use filler metals of equal or higher alloy content.
