Slitted coils
In addition to standard and special grade products, we alsoproduce high strength and ultra-high strength coils on our slitting lines. Thanks to our high capacities and flexible manufacturing technologies we can supply most requests at short notice. This is particularly relevant for our slitting lines, the engines that drive our steel service.
Computer-optimised shaft tipping, minimum process tolerances, ultrashortset-up times and automated production processes, including packaging, make Stahlo’s slitting lines particularly flexible and help us to provide made-to-measure slitted coils. We can supply standardand special grades from widths as small 10 mm.

Contoured blanks
Our site in Gera hosts one of the largest and most advanced blankinglines in Europe. It combines a 10,000 MPa press with a 4,750 – 2,750 mm tool table to produce trapezoids, parallelograms, O5 automotive body sheet blanks 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) Values for mechanical properties only apply to hot rolled products in black or chemically pickled and oiled states. It is irrelevant whether the products have undergone slightly cold re-rolling.2) Unless otherwise agreed at the time of ordering, nitrogen-hardening elements such as titanium and boron may be added at the discretion of the manufacturer.3) If the product is wide enough, the specimens for tensile testing must be taken perpendicular to the direction of rolling.4) See EURONORM 6 and EURONORM 12.

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 DC05.h) For design purposes, a minimum yield strength (Re) of 120 MPa may be assumed for steel grade DC05, 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.
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.

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.
1) Mechanical property values apply only to cold rerolled products.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 (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.

Coatings for common grades
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: The same formula applies to any other coating. 2) 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.

Special grades:Multiphase steel
High-strength hot steel strip with minimum strengths of 530 and 580 MPa when thermo-mechanically rolled. The material offers an attractive combination of properties of high strength plus good cold forming and welding qualities. It has specific benefits for producing reduced-weight, cold-formed parts. Its good dynamics makes it particularly suitable for parts in high vibration environments. Its high strain hardening capacity increases the yield strength of components considerably, particularly at low degrees of deformation.

Thermo-mechanically treated, hot rolled, high-strength, wear-resistant complex-phase steel
High-strength hot steel strip with minimum strengths of 800 – 950 MPawhen thermo-mechanically rolled. The material has an extremely finemicrostructure that – in complex interaction with the coordinated structural parts of ferrite, bainite, martensite and precipitation hardening – offers a particularly good property mix of high strength, wear-resistance and suitable cold forming and welding qualities. This type of steel is ideal for producing reduced-weight, cold-formed components, for example for automotive manufacturing.

Uncompromising material tests and quality records ensure maximumsafety standards. The mechanical properties and chemical values areessential for high-quality, cost-effective production. In our internal labora-tories we test materials tensile strength, yield strength, proof stressand elongation at failure. We use a vacuum emission spectrometer tocarry out chemical testing.
Non-contact measurement systems
Digital cameras on the slitting and recoiling lines measure each sheet inproduction to ensure that it meets the required length, width and diagonaltolerances.
We can provide specific test reports upon request to certify fulfilment of quality requirements.
Stahlo's internal barcode system traces all materials from the steel millright through to the final product.
