309S / C276 / Hex , , 20Cr 40Cr 45Cr Low Alloy Cast Steel Parts Steel Casting Low Alloy Steels add alloying elements such as nickel (Ni), chromium (Cr), and molybdenum (Mo) to attain specific properties. Depending on the alloying elements used, there can be great variation between different low alloy steels. The total alloy content can range from 2.07% to approximately 10.5%. For many low-alloy steels, the primary

AISI 4140 Seamless Pipe is tubing made to the pipe schedule. Alloy pipe in the power industry generally refers to A335 material, but in the oil and gas market, 4140 Pipe is used. This product is made to the pipe schedule but uses A519-4140 as the controlling Seamless specification.
