GNEE Astm Seamless Pipe America A512 Gr 4140

Grade 4140 steel pipe is a low-alloy steel pipe containing alloying elements such as chromium (Cr) and molybdenum (Mo). Despite the alloying elements, Grade 4140 steel pipes are generally more cost effective than some high-alloy steels. This makes it an affordable option in many applications, especially those requiring some strength and wear resistance.
Grade 4140 steel pipe usually has good machinability, which means that it can show good performance in machining, heat treatment and welding. Due to its reasonable balance of strength and machinability, Grade 4140 steel pipes are suitable for cutting, cooling, drilling, turning and other processing operations. This makes it easier to process into a variety of complex shapes and components in the manufacturing field.
