16CrMnNiMo9-5-2 Steel
Steel name: Ovako 277
Diagram No.: 2680
DIN designation: 16CrMnNiMo9-5-2
Chemical composition in weight %: 0.14-0.17% C, 0.15-0.30% Si, 1.20-1.40% Mn, max. 0.020% P, max. 0.002 S, 2.10-2.30% Cr, 0.45-0.55% Mo, 0.45-0.55% Ni, 0.15-0.25% V
Steel group: Alloyed steels
Properties: Ovako 277 steels has very good welding properties. The steels high hardenability and good toughness properties provide a heat-affected zone that meets the high stated demands for the bulk material. Ovako 277Q will be classified as a Group 3 steel according to the standard Welding - Guidelines for a metallic materials grouping system (ISO/TR 15608:2005). Depending on heat treatment execution (yield strength) Ovako 277Q may be classified into subgroup 3.1 or 3.2. Maximum hardness that may be obtained in the HAZ of Ovako 277Q will be 450 HV10kg.
Applications: Ovako 277 is an air hardenable steel that is suitable for case hardening, nitriding or quench and tempering. By using air-hardening or gas quenching it is possible to reduce the amount of quenching distortion. Additionally the use of quenching medias such as oil and salt can be avoided, which improves both safety and environment. It is produced in two quality classes.
