Description
1.7729
Titanium and boron are added to create1.7729 steel, which is a pearlitic boiler steel. It exhibits a high resistance to relaxation and creep while being relatively insensitive to notch action. Boron supplementation improves the body's ability to relax. The 20HMFTB steel products are used in their heat-treated state, where they exhibit a sorbitol-peroxide structure with carbides. This grade is not recommended for applications requiring a yield point greater than 80 kG/mm2. 20CrMoVTiB4-10 products are used in turbine couplings such as screws.Their operating temperatures range from 20°C to 550°C. EN 1.7729 steel is a special alloy steel designed specifically for primary forming into wrought products. The aforementioned properties apply to both the quenched and tempered states.
1.7729 is the material's EN numerical designation. 20CrMoVTiB4-10 is the EN chemical symbol.
