| Abstract: | With the rapid development of offshore industry, the requirements on mechanical properties of mooring chain accessory are also exigent. The heat treatment is the key process that will affect the perform- ance of R3S mooring chain accessory. This paper improves the heat treatment technology of quenching ＋ tempering for the traditional cycle. The influence of 890 -930 ℃ quenching ＋ （820 - 890）℃ secondary quenching ＋ tempering to impact toughness is studied to make sure the final properties meeting the requirements of classification societies. |
