Contoured blanks Our site in Gera hosts one of the largest and most advanced blanking lines in Europe. It combines a 10,000 MPa press with a 4,750 – 2,750 mm tool table to produce trapezoids, parallelograms, outer skin panels and standard blanks from 40 ton coils. We supply blanks as finished products, so your press capacity is optimised, and you can start forming straight away. We also reduce expensive scrap-handling in press plants since blanks and scrap have been seperated up front.

1 MPa = 1N/mm2 a) For products without a clear yield strength, the 0.2 % proof stress values (Rp0.2) are used as yield strength values. For other products lower yield strength values apply (ReL). For thicknesses < 0.7 mm and > 0.5 mm, the maximum yield strength values may be higher by 20 MPa. For thicknesses < 0.5 mm, the maximum yield strength values may be higher by 40 MPa. b) For thicknesses < 0.7 mm and > 0.5 mm, the minimum values for elongation at failure may be lower by 2 units. For thicknesses < 0.5 mm, the minimum values for elongation at failure may be lower by 4 units. c) r90 and n90 values apply only to a product thickness of > 0.5 mm. d) For thicknesses > 2 mm, the r80 value decreases by 0.2. e) It is recommended to process products made from DC01 steel within 6 weeks of being made available.
f) Unless otherwise agreed at the time of requesting a quotation and placing an order, steel grades DC01, DC03, DC04 and DC05 can be supplied as alloyed steels (e.g. using boron or titanium). g) For design purposes, a minimum yield strength (Re) of 140 MPa may be assumed for steel grades DC01, DC03, DC04 and DC06. h) For design purposes, a minimum yield strength (Re) of 120 MPa may be assumed for steel grade DC06, and 100 MPa for DC07 steel. i) For DC01 steel, the upper threshold Re = 280 MPa only applies for a period of 8 days after the product has been made available. j) Niobium may be used as a substitute for titanium. Carbon and nitrogen must be fully hardened.

1 MPa = 1N/mm2 Mechanical property values apply only to cold rerolled products. For products without a distinct yield strength, the yield strength values are used for the 0.2 % proof stress values (Rp0.2), otherwise for the lower yield strength (Re1). For thicknesses < 0.7 mm and > 0.5 mm, the maximum yield strength values may be higher by 20 MPa. For thicknesses < 0.5 mm, the maximum yield strength values may be higher by 40 MPa. 3) For design purposes, a minimum yield strength of 140 MPa may be assumed for steel grades DC01EK, DC04EK, DC03ED and DC04ED, while 120 MPa may be assumed for steel grades DC06EK and DC06ED. 4) For thicknesses < 0.7 mm and > 0.5 mm, the minimum values for elongation at failure may be lower by 2 units. For thicknesses < 0.5 mm, the minimum values for elongation at failure may be lower by 4 units. 5) The r values apply only to a product thickness of > 0.5 mm. For thicknesses > 2 mm, the r value decreases by 0.2. 6) Other methods of deoxidisation may be used, subject to agreement when the order is placed. In this case, the stability of mechanical properties and the period for the absence of stretcher strains must be agreed at the time of ordering. 1) 2)
For thicknesses > 1.5 mm, yield strength may reach a maximum value of 225 MPa. Niobium may be used as a substitute for titanium. Carbon and nitrogen must be fully hardened. 9) Other types of steel with the same mechanical properties may be supplied, subject to agreement when the order is placed. Chemical composition of these steels must be agreed on placement of the order. 10) Steel grades DC03ED and DC04ED typically undergo solid-state decarburisation. Carbon content as determined by parts analysis must not exceed 0.004 % after decarburisation. If expressly agreed at the time of ordering, steel grades DC03ED and ED04ED can be supplied as alloyed steels (e.g. using titanium or boron) without undergoing solid-state decarburisation. In this case, the maximum values for carbon and titanium contents are the same as for steel grade DC06ED. 11) Upon special customer request, steel grade DC04EK can be supplied with a thickness of 0.7 mm to 1.5 mm with Re < 210 MPa and A80 > 38%. It is then up to the manufacturer to select roughness values for matt surfaces within the applicable range. 7) 8)

The values for mechanical properties only apply to products that were rerolled cold prior to surface refinement. 2) For products without a distinct yield strength, the yield strength values are used for the 0.2 % proof stress values (Rp0.2), otherwise for the lower yield strength (ReL). For thicknesses < 0.7 mm and > 0.5 mm, the minimum yield strength values may be higher by 20 N/mm2. For thicknesses < 0.5 mm, the minimum values for elongation at failure may be lower by 4 units. 3) For thicknesses < 0.7 mm and > 0.5 mm, the minimum values for elongation at failure may be lower by 2 units. For thicknesses < 0.5 mm, the minimum values for elongation at failure may be lower by 4 units. 4) r90, n90, r and n values apply only to a product thickness of > 0.5 mm (cf. ISO 10113 and ISO 10275). 5) For thicknesses > 0.2 mm, the r90 or r value decreases by 0.2. 6) It is recommended to process products made from DC01+ZN steel within 6 weeks of being made available. 1)

Coating thickness can be calculated as follows using the coating weight. Example: A zinc coating of 100 g/m2 on both sides corresponds to an approximate zinc coating thickness of 7.1 μm on each side:
1)
Zinc coating weight (g/m2, two sides) = Zinc coating thickness (μm per side) 2 x 7.1 (= zinc density) The same formula applies to any other coating. The end-user may assume that these threshold values are observed for both top side and underside. 3) The coating weight is determined using chemical separation. For hot-dip zinc-plated flat products the procedures as outlined in DIN EN 10346 are used. The same formula applies to any other coating.
