You can get the result in your picture with a Principled BSDF, some Metallic, and some Roughness. You may want a roughness closer to 0, I’d say .15 would be perfect- but a big part of what you’re seeing is geometry based. There’s a very sharp crease a quarter of the way down that metal rod. You aren’t going to be able to texture that (you could, but it’ll be a pain)- instead, you need to match the geometry to see that same creasing
