Effect of technological transformations on the hydrogen resistance of cast stainless steel

We investigate the mechanical properties of a cast stainless steel widely used in the engineering industry. Experiments were carried out in gaseous hydrogen under a pressure of 35 MPa. We established a slight hydrogen embrittlement of steel subjected to a high-temperature, gas-static treatment. This...

Description
Summary:We investigate the mechanical properties of a cast stainless steel widely used in the engineering industry. Experiments were carried out in gaseous hydrogen under a pressure of 35 MPa. We established a slight hydrogen embrittlement of steel subjected to a high-temperature, gas-static treatment. This steel can be successfully used in brazed and welded structures. The appearance of "hydrogen cracks" in a metal in the process of elastoplastic deformation is most probable in the zone of a weld seam. Materials mentioned: 07Kh25N16AG6F steel and 10Kh18N11BL steel.
