Study on interrupted turning of hardened steels with PCBN tools

Alloy steels are basically carbon steels with additional elements added to alter the characteristics and bring about a predictable change in the mechanical properties of the alloyed metal.

The low temperature fracture mechanism of high manganese austenitic steels is studied.

The microstructure and property of the free cutting unquenched plastic die steels have been studied.

The ferrous metals can be classified into steels, cast irons, and wrought irons.

The deformation resistance models of two steels during hot rolling have been established with regression analysis of reasonable structural formula.

Simulations of surface nitridation and nitride precipitation in alloy steels have beeb carried out with cellular automaton modeling.

It also includes application steels for Bridges, pipes, pressure vessels, automotive manufacturing, shipbuilding and welding steel grades.

The clogs on the submerged entry nozzle of type 304 and 321 stainless steels were investigated, and the mechanisms of clogging were discussed.

The new domestic - developed plastic mould steels include prehardening steel . age hardening steel, quenching-tempering steel, cold -forming steel, and anti - corrosion steel, etc.

Wear loss of specimens for these two steels during a certain time show that low carbon high alloy steel is much more resistant to corrosive impact abrasion than high manganese steel.

The results of measurement of the "C" curve show that the steels designed have a high bainitic hardenability and the uniform structure within a bigger cross section can be obtained.

"The element is used to harden certain steels, among other metallurgical uses, and is also used in semiconductor devices. Its borate compounds, in which it has valence 3, are essential to plant growth and have many uses in soaps, mild antiseptics, and eye ointments."
