  • Alloy steel composition and chain products fabricated in such alloy steel
    Patent number: 6146583
    Abstract: A steel alloy for fabricating into chain links particularly for a mining chain having a composition including nickel in the range of 0.3 to 1.5%, particularly 1%, chromium in the range of 0.2 to 1.0%, particularly 0.5%, molybdenum in the range of 0.1 to 1.0%, particularly 0.75%, carbon in the range of 0.15 to 0.28%, particularly 0.23%, vanadium in the range of 0.05 to 0.2%, particularly 0.1%, and the balance iron. The steel alloy enables the fabrication of mining chain having an acceptable stress corrosion resistance to aggressive conditions likely to be encountered in mining without sacrificing hardness and strength in comparison with a conventional composition steel chain.
