Hardening & Tempering Steel Edge Conditioning In-Line Surface Finishing Hardening and Tempering of Steel Strip Teilen Simply put, hardening & tempering is the process of transforming cold-rolled steel into high-strength spring steel through a series of heat-treating operations. These operations are performed at voestalpine Precision Strip WI in Pleasant Priarie in state-of-the-art, continuous heat-treating furnaces manufactured by EBNER, Austria - the universally acknowledged world-wide leading manufacturer of such facilities. The design and execution of these furnaces enables us hardening & tempering a range of high-carbon and alloyed strip grades to exacting tolerances with respect to both geometrical and mechanical properties. The technology also allows a range of material microstructures from a fully bainitic structure through a fully martensitic structure. Range of dimension inch mm Width range 0.250" - 25.000" 6,35mm - 635,00mm Thickness Range 0.004" - 0.094" 0,10mm - 2,40mm Click to enlarge Standard Hardness Values The range of standard hardness values for our hardened and tempered strip steel is a function of the material thickness and the intended application. The attached table is to be utilized as guideline. Low range: recommendation for applications where a higher degree of bendability / formability is desired e.g. band saw types Mid range: recommendation for flat springs and valve steel applications where also blankability is required High range: recommendation for certain blanking applications and for material such as power springs View into furnace. Click to enlarge Thickness Tolerances voestalpine Precision Strip WI offers a standard thickness tolerance T3 according to the internationally accepted Swedish Tolerance Table. Continuity of a precision thickness tolerance has a direct effect not only on part functionality in many applications but also on the processing parameters of specialty operations used manufacturing those products. It can even directly impact the cost of those operations when considering issues such as die life in precision stamping or the grinding of strip edges.
