The Cr-Mo alloy electrode is preferable for welding structural steel. While welding in order to harden soft annealed O1 tool steel, the steel should be heated to hardening temperature, cooled to 500°C ...

Precipitation hardening stainless steels can be supplied in a readily machineable condition. After fabrication, a single, low temperature heat treatment can dramatically increase the strength of the ...

Induction hardening is another case-hardening process. Parts are heated by electromagnetic induction, then rapidly quenched by a spray of water or polymer solution. Unlike carburizing, induction ...

hardening. Process of increasing the surface hardness of a part. It is accomplished by heating a piece of steel to a temperature within or above its critical range and then cooling (or quenching) it ...

It is evident for heat treatable aluminum alloys, that a great reduction in mechanical properties was reported against the fusion arc welding process. This is considered an utmost industrial issue and ...
