Abstract

A találmány tárgya acéllemez, amelynek szívós/ridegátmeneti hőmérséklete (DBTT) mind az alaplemezben, mind ahőterhelésnek kitett tartományban (HAZ) legfeljebb mintegy -73 °C,szakítószilárdsága legalább mintegy 830 MPa, továbbá mikroszerkezetedöntően megeresztett finomszemcsés lemezes martenzitből, megeresztettfinomszemcsés alsó bénitből vagy ezek keverékéből áll. A találmánytárgya emellett az ilyen acéllemez előállítására szolgáló eljárás,valamint az acéllemez HAZ-a legfeljebb -73 °C nagyságú DBTT-énekbiztosítására szolgáló eljárás is. ÓThe subject of the invention is a steel sheet with a tough/brittle transition temperature (DBTT) both in the base plate and in the heat-stressed area (HAZ) of up to -73 °C, a tensile strength of at least 830 MPa, and a microstructure mainly made of tempered fine-grained lamellar martensite, tempered fine-grained lower benite or a mixture of these stands The subject of the invention is also a method for the production of such a steel plate, as well as a method for ensuring the HAZ of the steel plate at a maximum DBTT of -73 °C.
