Synopsis : The characteristics of the weldable ferritic stainless steel, RIVER LITE 434 LN-2, produced by SS-VOD process, are reviewed. In order to improve its toughness. C and N contents of the steel have been reduced to extremely low levels and Nb and Al added. The weld joint made under the suitable welding conditions also is superior in toughness. Therefore, the steel plate up to about 12 mm in thickness for structural use above a temperature 0 can be manufactured. Being excellent in pitting corrosion resistance and free of stress corrosion cracking, the plates are suitable for the use as vessels in wet corrosive environment and have mainly been applied to hot water reservoirs. |
