Steel 5160

Annealing Procedure

Heat to 1450 F and air cool.

Applications

Commonly employed in heavy spring applications primarily in the automotive field for leaf springs.

Forgeability

Forge this grade between 2100 and 2200 F.

Heat Treatability

5160 is normally hardened in oil. Recommended quenching temperature is 1525 F, with a wide range of mechanical available by tempering between 800 and 1300 F.

Machinability

Machining this grade can be very difficult in the "as rolled" condition, and the alloy should be annealed prior to machining to obtain maximum speeds and feeds.

Principle Design Features

5160 is a carbon-chromium spring steel. It exhibits excellent toughness and high ductility, with a high tensile-yield ratio.

Weldability

Weldability is poor in this alloy due to its high carbon and chromium content. For best results, preheat the section and stress relieve after welding. Either gas or arc welding methods may be used.
