Document Type and Number:
Japanese Patent JP2002515093
Kind Code:
A
Abstract:
A high strength, high toughness, low carbon/low manganese steel is provided that is further resistant to stepwise cracking and sulfide stress cracking. The steel can be produced by conventional or thin slab casting techniques using normal speeds, with low manganese segregation levels. The steels are excellent candidates for linepipe applications in severe sour gas service.
