Hastelloy B2 stud bolts are made of nickel-molybdenum alloy which are known for their outstanding resistance to reducing environments, such as sulfuric, acetic and phosphoric acids, hydrogen chloride gas and other non oxidizing gases. They have excellent resistance to pitting and stress corrosion cracking, while they are not recommended in oxidizing chemical media in the presence of ferric or cupric salts. These stud bolts can be used in as-welded condition as they resist the formation of grain-boundary carbide precipitates in the weld heat-affected area.
Due to their reliable performance they are widely accepted in the areas of geothermal, solar energy, oil and gas, chemical and pharmaceutical industries. The benefits of Hastelloy B2 stud bolts are high resistance to uniform attack, outstanding localized corrosion resistance and excellent stress corrosion cracking resistance. They have high temperature strength in
