1: 4118 steel introduction
4118 Steel one steel grade in ASTM A29 standard. ASTM 4118 steel is one of popular alloy steel used for engineering purpose, like fasteners, high pressure pipe and more advanced carburized parts, such as gear, shaft, etc. which work in the noncorrosive medium and temperature below 250 ºC, working with nitrogen hydrogen mixture in the medium.
