| Use advice for data set | Scope: This declaration applies to 1 metric tonne of XCarb® Recycled and Renewably Produced Magnelis® coated steel produced at ArcelorMittal. The Life Cycle Assessment is based on the LCA model and data for ArcelorMittal XCarb® Recycled and Renewably Produced Hot Rolled Coils, coupled with downstream processes at ArcelorMittal plants, covering 100% of the production of the declared product. System boundary: Type of EPD: cradle to gate with modules C1–C4 and module D (A1-A3, C and D) Modules A1-A3 of the XCarb® Recycled and Renewably Produced hot dip galvanized steel with Magnelis® coating production include: The provision of resources, additives, and energy Transport of resources and additives to the production site Transport of intermediate products within ArcelorMittal sites Production processes on site include energy, production of additives, disposal of production residues, and consideration of related emissions. Recycling of production/manufacturing scrap. Steel scrap is assumed to reach the end-of-waste status once is shredded and sorted, thus becoming input to the product system in the inventory.Module C1 assumes a generic multi-story building demolition scenario. Module C2 includes impacts of assumed distances of 100 km from the demolition site of a scrap processing plant and 200 km from this plant to the disposal. In both cases, empty returns of transport were assumed. Module C3 takes into account the sorting and shredding of after-use steel to allow its orientation towards the recycling solutions. This process will also produce losses due to efficiency that will be oriented towards landfill sites. A conservative value of 2 % landfill is then considered in C4. Module C4 takes into account the waste disposal including physical pre-treatment and management of the disposal site. Steel is an inert material which does not require any specific treatment on disposal site. Module D refers to the end of life of the structural steel, including reuse and recycling | ||
| Technical purpose of product or process | XCarb® Recycled and Renewably Produced hot dip galvanized steel with Magnelis® coating can be used in various industrial applications, such as: Construction: structural or non-structural profiles, roofing & cladding, decking, cable trays, expanded metal, gratings, composite flooring, concrete moulds Road and railway infrastructure: safety barriers, protection equipment, sound insulation wall panels, walls providing protection against hail Agriculture and farming: barns, greenhouse structures, agricultural equipment Solar energy generation: structures for photovoltaic plants Tubular applications: structural tubes for scaffolding, road signals, poles.The coated steel is delivered in wide coils, slit coils, blanks or sheets. It can be processed by all conventional processing operations used for hot dip galvanized steel: bending, drawing, clinching, profiling, stamping, welding etc. The friction coefficient of XCarb® Recycled and Renewably Produced hot dip galvanized steel with Magnelis® coating is lower than the one of standard hot dip galvanized steel and is stable during cold forming operations. | ||

| General comment on data set | This Environmental Product Declaration refers to XCarb® Recycled and Renewably Produced hot dip galvanized steel with Magnelis® Coating. The product is a double-sided hot-dip galvanized carbon steel coated on both sides with a zinc-aluminium-magnesium alloy. This alloy, composed of 93.5 % zinc, 3.5 % aluminium and 3 % magnesium, is applied by means of a continuous hot dip galvanizing process. A post-treatment (passivation, thin organic coating and/or oiling) can also be applied on the product. This chemical composition has been selected to provide an excellent corrosion resistance. XCarb® Recycled and Renewably Produced hot dip galvanized steel with Magnelis® Coating is compliant with EN 10346. The coated steel is available in a very wide range of steel grades (steels for cold forming and deep drawing applications, structural steels and High Strength Low Alloy steels), and coating masses (from 70 to 800 g/m²). ZM is the symbol used in EN 10346 to refer to Zinc Aluminium Magnesium coatings to which Magnelis® coated steel belongs. | ||

| Technology description including background system | This Environmental Product Declaration refers to a double-sided hot dip galvanized coated steel, consisting of steel substrate with a specific metallic alloyed zinc coating, Magnelis®, applied by means of a continuous hot dip galvanising process. Magnelis® coated steel is a hot-dip galvanized carbon steel coated on both sides with a zinc-aluminiummagnesium alloy. This alloy, composed of 93.5% zinc, 3.5% aluminium and 3% magnesium, is applied by means of a continuous hot dip galvanising process. The substrates can be made of different steel grades with Magnelis® coating ranging from 90 to 430 g/m²and steel thicknesses ranging between 0.20 mm and 6.0 mm. The product is manufactured by through the secondary route, in which different steel scraps are melted in an electric arc furnace to obtain liquid steel. This steel is then refined in a ladle furnace with addition of ferroalloys and metals to obtain the required steel characteristics. The steel is then casted at a continuous caster to obtain semi-finished products as billet or blooms. These products are then rolled to the desired size. The following operations are two rolling processes: the hot strip mill and the cold rolling mill. In the hot rolling mill the slab is reshaped above the recrystallization temperature. The qualities obtained in this process are e.g. strength and surface quality. During the rolling process the material passes through the furnace and the rolling line. In the furnace the metal is preheated by natural gas. There is no need for an additional warming, if the hot slabs are directly charged into the rolling mill. The forming is done in various rolling frames until the final shape is obtained. The steel scrap in this process are directly recycled. In the cold rolling mill the material is reshaped below the recrystallization temperature. Thereby a enhanced surface quality, an improved dimensional accuracy as well as a higher strength are achieved. The different process steps are: pickling, the rolling line and the heat treatment. The rolled coil can be then metallic coated with Zinc, aluminium and magnesium. This product comes from a production process flow which only uses XCarb® Recycled and Renewably Produced Hot Rolled Coil. Technical data: Due to its 3 % magnesium content, XCarb® Recycled and Renewably Produced hot dig galvanized with Magnelis® coating offers self-healing on cut edges and corrosion resistance in chloride and ammonia atmospheres. This high corrosion resistance means that less metallic coating is required to ensure an equivalent corrosion protection than with standard hot dip galvanized steels. The coating process can apply various thickness of the Zinc Aluminium Magnesium layer, up to 800 g/m² (total of both sides). Specific mechanical properties are defined for each steel grade used as substrate and measured according to EN ISO 6892. The corrosion resistance performance can be evaluated with different indoor and outdoor tests. One of the most common tests is the ‘Salt Spray Test’ defined according to EN ISO 9227/ASTM B-117. Declared unit: The declaration refers to the functional unit of 1 metric ton of double-sided XCarb® Recycled and Renewably Produced hot dip galvanized steel with Magnelis® coating, packed and ready to be transported from ArcelorMittal to its clients as specified in Part B requirements on the EPD. The results are calculated based on a 1.5mm steel thickness with 310 g/m² Magnelis® coating. The steel substrate has been elaborated from an XCarb® Recycled and Renewably Produced Hot Rolled Coil. | ||
