The impact energy of low-strength metals that do not show a change of fracture mode with temperature, is usually high and insensitive to temperature. For these reasons, impact tests are not widely used for assessing the fracture-resistance of low-strength materials whose fracture modes remain unchanged with temperature. Impact tests typically show a ductile-brittle transition for low-strength materials that do exhibit change in fracture mode with temperature such as bod… WitrynaANSI / NACE MR0175 / ISO 15156 lists the requirements for carbon steels, low alloys and corrosion resistant alloy exposed to H2S in oil and gas exploration and production environments.
