Recently, due to the 8-month Russia-Ukraine conflict and the coming winter, the European energy crisis has been intensifying. Natural gas prices in many places have reached record highs, and LNG ship freight rates have continued to rise. Experts say the situation may be worse next year.

Use diamond cone or quenched steel ball indenter to press the indenter into the material surface under the action of test pressure F. After holding for a specified time, remove the main test force and maintain the initial test force. Calculate the hardness value with the residual indentation depth increment. During actual measurement, the Rockwell hardness value can be directly read out through the dial of the testing machine.

UNS N10276 is a tungsten-containing nickel-chromium-molybdenum-alloy with very low silicon and carbon content. The alloy has excellent corrosion resistance to most corrosive media in both oxidizing and reducing states. Excellent resistance to pitting corrosion, crevice corrosion and stress corrosion cracking. The alloy is suitable for use in various chemical process industries containing oxidizing and reducing media. Hastelloy C-276 is one of only a few materials that are resistant to moist chlorine, hypochlorite and chlorine dioxide solutions, and the alloy has significant resistance to high concentrations of chloride solutions (e.g. ferric chloride and copper chloride).
