Heat Treatment of Bolts Fasteners

About 90 percent of fasteners are steel based and the required strength level is usually developed in steel fasteners using quenching and tempering processes. Accordingly, the terms "high strength" with "heat treated" or "hardened" are often equivoed with the fastener world. However, heat treatment includes a wide range of processes.

Effect of heat treatment on microstructure and wear ...

The high manganese steel surfacing layer was deposited on Q235 steel by fluxcored wire gas shielded welding. The aswelded surfacing layer was heated at 1050∘C and quenched in the water, then was tempered at 300∘C. The microstructure, hardness and wear resistance of aswelded surfacing layer and that after heat treatment were comparatively analyzed.

Manganese Steel

Thus high heat input rate processes such as electroslag generate a relatively coarsegrained weld metal, while that produced by other processes is relatively fine. Weld metal usually contains a relatively high density of disloions, which also contributes to increased yield strength in carbon and carbon–manganese steels.

Thermal Center

Since a substantial increase in hardenability only occurs at high austenitizing temperatures, one must be concerned about the resultant properties of the steel. Finegrain steels promote a somewhat greater toughness and shock resistance and have less of a tendency to crack in heat treatment. Coarsegrain steels tend to harden more deeply.
