Abstract

1345924 Steel VALLOUREC (USINES A TUBES DE LORRAINE - ESCAUT ET VALLOUREC REUNIES) 16 Sept 1971 [18 Sept 1970] 43202/71 Heading C7A Steel, for making tubes suitable for use in extracting petroleum or natural gas, comprises:- C 0À25-0À35% Cr 0À5-1À1% Mn 0À6-0À82% Mo 0À21-0À33% Si 1À2-1À42% Al less than 0À03% P less than 0À07% and S less than 0À05% the balance, apart from impurities, being Fe. The steel has good mechanical properties and is resistant to embrittling by hydrogen and acids.
