Steel GX5NiS36-HIP vs GX5NiS36-SR

Steel · GX5NiS36 temper comparison

GX5NiS36-HIP and GX5NiS36-SR are two conditions of the same steel grade, GX5NiS36: HIP (hot isostatic pressed) versus SR (stress relieved). The chemistry is identical, so every difference below comes from the condition. GX5NiS36-HIP is the stronger of the two: tensile strength 450 MPa (65.3 ksi) against 420 MPa (60.9 ksi) for GX5NiS36-SR, about 7% more. GX5NiS36-HIP is the more ductile: elongation 18% versus 12% for GX5NiS36-SR.
