Steel is an alloy of iron usually containing less than 1% carbon. The process of steel production requires several sequential steps. The two types of steelmaking technology in use today are thebasic oxygen furnace(BOF) and theelectric arc furnace(EAF). Although these two technologies use different...
High Alloy Steel Alloy consisting of inactivated or not austeniticaferrica ActinicSteel is to be austenitic-ferritic at a 1:1 ratio of austenite to ferrite and contains particular alloy elements. The principal feature is, limiting the sulphure content to below 0.005% in order to obtain a ...
Steel, alloy of iron and carbon in which the carbon content ranges up to 2 percent (with a higher carbon content, the material is defined as cast iron). By far the most widely used material for building the world’s infrastructure and industries, it is u
The crucible process allowedalloysteels to be produced for the first time, since alloying elements could be added to the molten metal in the crucible, but it went into decline from the early 20th century, as electric-arc furnaces became more widely used. It is believed that the lastcrucible ...
carried out innovative processes including the intercritical rolling and controllable annealing of medium-carbon low-alloy steel, leading to a microstructure consisting of a large number of nanoscales Fe3C precipitates in the UFG ferrite matrix [4]. The good combination of high-strength plasticity is ...
1930 Technology Avesta Ironworks from Sweden produces duplex stainless steel for the first time, with the microstructure of the alloy consisting of both ferrite and austenite. Sweden 1930 Technology The Chrysler building is completed in New York City. It is the first to feature stainless steel roof...
Nickel alloy steels are alloys consisting of nickel, with additional metals and chemicals, depending on what type of properties the alloy should have.
An efficient thermal-structural numerical solver for Additive Manufacturing has been developed based on a modified Lagrangian approach to solve the energy conservation equations in differential form. The heat transfer is modeled using the finite difference method applied to a deforming Lagrangian mesh. The...
Parts made of a heat-treated alloy steel having a minimum tensile strength of 700 N/mmand a notch toughness of at least 55 joules, wherein the alloy steel is a Mn/Cr/Nb alloy steel of lower alloy content than has hitherto been used to provide the desired strength/toughness properties.收...
