12. Graphite carbon. As the annealing temperature is too high, holding time is long, so that the steel in the long slow cooling process, carbide easily decomposed into free carbon, i.e. graphite. Figure 18 is T12A steel graphite carbon microstructure (etched in 4% alcohol bitter acid solution ).
Cold Worked Steels American Galvanizers AssociationAny form of cold-working reduces steel's ductility. Operations such as punching holes, notching, producing fillets of small radii, shearing, or sharp bending may lead to strain-age embrittlement of susceptible steels. Cold-worked steels less than 1/8" (3 mm) thick subsequently galvanized are unlikely to experience strain-age embrittlement.

Giuseppe Pintaude et al. Plastic Deformation Analysis of Carbon Steel Due to Metal Hole Punching Using Coated and Uncoated Tools This paper presents subsurface hardening results of the low-carbon steel plate, deformed under industrial test conditions by punches manufactured in quenched and tempered AISI D2 steel, with and without TiN coating. The punches are 12º double shear angle shaped. A

Steels are also characterized by the type of processing (Hot-rolled, Cold-rolled, Galvanized, etc.), by their chemistry (High-carbon, Low-carbon, etc), and by their general characteristics (Abrasion resistant, Floor Plate, Weathering, etc.). As an industrial steel supplier, Steel Warehouse carries a variety of steels.
Maximum sheet metal punching, minimal distortionA clearance that is too tight makes the tooling work harder; more heat transfers to the punch tip and the sheet, again adding to distortion. Also watch out for punch deflection, especially if youre working with small hole diameter-to-material-thickness ratios:2-to-1 for stainless, 1-to-1 for carbon steel,

High-speed tool steels are also used for many punching and forming tools. Originally developed for non-cutting tools, these ex- hibit particularly high wear resistance, high hardness at elevated temperatures and thus good tempering resistance. High-speed tool steels have a carbon content of between 0.8 % and 1.4 %.

What is Laser Cutting? St. Anns Sheet MetalThe minimum hole sizes are related to stock thickness and can be as low as 20% of the stock thickness, with a minimum of 0.25 mm (0.010 in) for upto 1.9 mm (0.075 in). Contrast this with normal piercing operations with the recommended hole size 1.2 times the stock thickness. Burrs are quite small compared to blanking and shearing.
