ThesaurusAntonymsRelated WordsSynonymsLegend:
Noun1.quenched steel - steel that has been hardened by immersing it in water or oil to cool it
steel - an alloy of iron with small amounts of carbon; widely used in construction; mechanical properties can be varied over a wide range
martensite - a solid solution of carbon in alpha-iron that is formed when steel is cooled so rapidly that the change from austenite to pearlite is suppressed; responsible for the hardness of quenched steel
oil-hardened steel - steel that is quenched in oil

This creates an outer layer that passes the tests conducted by the Bureau of Product Standards of the Department of Trade and Industry.However, tests done by the BPS do not expose the danger that could arise from these quenched steel bars, which should not be welded, bended, threaded and galvanized.
Despite the long and detailed technical presentation on how quenched steel bars are being manufactured, the steel manufacturers failed to prove that quenched steel bars in high rises can withstand cyclic loading in the event of a severe earthquake Seismic Zone 4 country such as the Philippines.
The wear life of HX900 wear segments is about five times longer than white iron and 20 times longer than quenched steel, according to the company.
The topics include measuring and predicting residual stresses in heat-treated large forgings, modeling induction heat distribution in carbon-fiber-reinforced thermoplastics, computer modeling mechanical properties and microstructure in a quenched steel specimen, the numerical simulation of phase transformation during the hot stamping process, and reducing gear size for compact transmission design by selecting steel grade and heat treatment processes with computer modeling.
The presence of martensite in quenched steel, while greatly increasing its hardness and tensile strength, causes the material to be brittle as its formation is accompanied by severe matrix distortions.
