Processing steel straight from the line.

Stahlo is one of the advanced state-of-the-art and largest independent steel service centres in Germany. We offer a complete range of products and services for all relevant materials in the sheet metal market.

At our German sites in Dillenburg and Gera we produce for our custo-mers´ individual needs slitted coils, cut-to-size sheets, standard sheets, blanks, and contoured blanks in any typical grade, including high strength and ultra-high strength steels.

With our technical application consultancy service you will find the right steel grade for your requirements. Qualified customer service is our priority.

We use the full range of SAP information and communication technologies,including SAP's automotive module, to provide optimum products and services for you.Certified according to DIN ISO/TS 16949, Stahlo ensures that you receive the quality and flexibility you need to gain the competitive edge.

And wherever your site is located – Stahlo will deliver just in time.

Stahlo offers a number of benefits:

Longtime experience in the international steel market Technical application consultancy at the beginning of the planning and development stages

World-wide and independent supply chain competency Efficient material stock-keeping and continous delivery readiness Processing high strength and ultra-high strength steel with a tensile

Range of products: Slitted coils

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, 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) 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.

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.

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.

7) For thicknesses > 1.5 mm, yield strength may reach a maximum value of 225 MPa.8) 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.

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.

1 MPa = 1N/mm2



28 29

a) For a distinct yield strength, the lower yield strength values Re1 apply.b) Special agreements must be made for thicknesses > 1.2 mm.c) For thicknesses < 0.7 mm and > 0.5 mm, the minimum values for elongation at failure may be lower by 2 units.

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.

Zinc coating weight (g/m2, two sides) 2 x 7.1 (= zinc density)

= Zinc coating thickness (μm per side)

Mechanical testing

A video extensometer provides accurate and relevant records of mechani-cal material behaviour under tensile load over a specific period of time.

Chemical testing

A vacuum emission spectrometer is used to quickly analyse the percentage of up to 16 different elements in sheet steel.

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.

Traceability of requirements

Stahlo's internal barcode system traces all materials from the steel millright through to the final product.

We can provide specific test reports upon request to certify fulfilment of quality requirements.
