Material: Cold extruding steel

Information about the selected material

High-quality standard components in general mechanical engineering , apparat construction , engine and vehicle. In a series of operations (upsetting , extrusion , pressing, widening , drawing with intermediate surfaces and annealing treatments) parts can be manufactured in various forms, which have large density, a low for the stress fiber pattern, very good surface finish and high dimensional accuracy. The performance characteristics of the finished parts can be improved, because the cold forming as a result of hardening hardness , tensile strength and yield strength increase. It is also possible from case to case to satisfy very high requirements with unalloyed steels, which can be normaly done by manufacturing of parts (just by machining and heat treatment) only with alloy steels otherwise. The smooth surface, in conjunction with the high residual stresses of the work-hardened edge zone to increased vibration and fatigue strength. In addition, these surface features due to its adherent phosphate layer very favorable operating characteristics and good wear resistance. With the ability to customize the fiber texture of the part shape, adverse notch effects can be avoided.

The deformation under pressure in steel tools, both the size of the forming and the steel grade used by the maximum permissible surface pressure between the workpiece and the tool there is a limit. The selection of materials depends primarily on the shape of the component, the necessary cold working and the necessary mechanical values of the finished part.

Cold formed workpieces can also be heat treated, quenched and tempered or hardened steel depending on quality.
