steel/ propertiessteelschemical compositionstrengthhot rolled steelsnormalizationWith the same carbon concentration, the strength of hot rolled steels with niobium is 5–10 kg/mm 2 higher than that of carbon steels. The increase in strength due to niobium additions is greatest for 0.10–0.20% C. ...
An immediate problem was the lack of physical property data for sintered steel, so that an initial requirement of the experimental programme described in this paper was to determine relevant physical properties. Subsequent objectives were to investigate the effect of electromagnetic variables on preform ...
High strength, low alloy steel is produced, preferably as a hot rolled article (e.g. strip), to have a rimmed skin of essentially ferrite while having a main body or core which is aluminum-killed and comprises, for superior mechanical properties including yield strength, a suitable quantity ...
High-strength low-alloy (HSLA) steels, also known as microalloyed steels, are designed to provide improved mechanical properties and greater resistance to atmospheric corrosion. They typically have low carbon content (0.05% to 0.25%) to ensure adequate formability and weldability, with manganese conten...
Effect of welding process on the microstructure and properties of dissimilar weld joints between low alloy steel and duplex stainless steel To obtain high-quality dissimilar weld joints, the processes of metal inert gas (MIG) welding and tungsten inert gas (TIG) welding for duplex stainless ste.....
AISI 4140 alloy steel can be welded using all conventional techniques. However, the mechanical properties of this steel will be affected if it is welded in the heat treated condition, and post weld heat treatment should be performed.Heat Treament AISI 4140 alloy steel is heated at 845°...
By this term is meant not only the ability to be welded readily and satisfactorily by the usual 0 commercial methods, but also the ability of the steel adjacent to the weld to retain, after welding, substantially all of its original desirable properties. Some of the low alloys steels are ...
Influence of Warm Tempforming on Microstructure and Mechanical Properties in an Ultrahigh-Strength Medium-Carbon Low-Alloy Steel Influence of warm Tempforming on microstructure and mechanical properties in an ultrahigh- strength medium-carbon low-alloy steel[ J].

The steel may be intermediately annealed after cold rolling and then further cold rolled. The cold rolled steel can then be coated, such as by hot dip galvanizing, hot dip galvannealing, hot dip aluminizing, or electrogalvanizing. Improved tensile properties for embodiments of the present alloys...
Structure and properties of low-alloy tungsten-free high-speed steelsThe additional microalloying of K41 steel does not lead to a significant change in its properties and the quantity of nonmetallic inclusions increases. As the result of the increased chromium content in it (6% instead of 4%) ...
