Ensinger PEI
Ovako 20NiCrMo7 157D Steel, Quench & Tempering
Categories: Metal; Ferrous Metal; Alloy Steel; AISI 4000 Series Steel

Material Notes: General Information: Ovako 157 is a high cleanliness case hardening steel used for bearing and transmission components. There are three different modifications of the grade.
157C - Bearing quality (BQ) variant with low sulphur content
157D - Bearing quality (BQ) variant with low sulphur content
157G - Regulated sulphur content for improved and consistent machinability

BQ-Steel(Bearing Quality) is a bearing quality clean steel optimized for fatigue strength by a strict control of steel cleanliness. BQ-steel is also ideal for new design solutions in a wide array of demanding applications outside the bearing industry that require longer performance and higher loads. The BQsteel offer is the result of the Ovako clean steel program. Purity of production means that the material has significantly smaller inclusions compared to conventional steel and, as a result, the fatigue strength of the steel is increased dramatically. Use of the material allows components to be manufactured in smaller sizes. The BQ-steel has for decades been the problem-solver.
