Abstract
The results of complex tests of new cold-resistant "Arc"-indexed steels with guaranteed yield strength 355 - 390 and 750 MPa are submitted. Standard mechanical characteristics, ductile-to-brittle transition temperatures Тk and Тkb, nil ductile temperature NDT, crack tip opening displacement CTOD of base metal and HAZ, corrosion-mechanical strength are determined. The developed "Arc"-indexed steels are applicable for any Arctic marine structures elements without limitations at service temperatures down to —40 °C. Data on fundamental technological schemes and technology development providing high performance characteristics of thick rolled plates at low temperatures in accordance with the RS Rules requirements for "Arc"-indexed steels are also presented.
Keywords: low-alloyed "Arc"-steel, high-strength steel, mechanical properties, working capacity, cold-resistance, crack resistance.
