Relating to iron.
The surface appearance of the various metals after final treatment.
Temperature of final hot working of a metal.
A process of softening a metal by the application of heat from a high-temperature flame.
A process of hardening a ferrous alloy by heating it above the transformation range by means of a high-temperature flame, and then cooling as required.
A flat cold-rolled, prepared-edge section up to .25″ wide, rectangular in shape.
Metal in any width but no more than about 0.005″ thick.
Surface appearance of metals when broken.
Nicking and breaking a bar by means of sudden impact, to enable macroscopic study of the fracture.
Used principally on iron and steel, means heating the metal to about 100°F above the critical temperature range, followed by “soaking” and slow cooling below the critical temperature.
Full Finish Plate:
Steel sheet or strip reduced either hot or cold, cleaned, annealed and then cold-rolled to a bright finish.
Full Hard Temper:
In low carbon sheet or strip steel, stiff and springy, not suitable for bending in any direction. It is the hardest temper obtainable by hard cold rolling.
