JSW Steel Piombino (part of JSW Steel Italy/JSW Group) is an iron and steel company which bought Lucchini plant located in Piombino (Italy). PIOMBINO has been for long time one of the most important manufacturers in Europe, leader in the production of long steel products for high quality and special steels.
With the acquisition of Piombino Plant, JSW Group got all the brands and know how developed in over 100 years of steel history. JSW Steel Piombino's activity involves the production of a wide range of quality and special steels, with different shapes and sizes for Rails, Wire Rod and Bars. They are destined to different sectors: Railway, Automotive, Earth Moving Vehicles, Energy, Fastening, Springs, Welding.
JSW Steel Italy controls the companies JSW Steel Piombino, GSI Lucchini and Piombino Logistics. It is part of the JSW Group: Indian steel leader, also present in Europe and America, active in the steel, energy, infrastructure, ventures and cement businesses. The JSW Group is also active in the life of people with the Jindal Foundation, sustainability projects and sports.
In 1865 it was constructed the first metallurgical plant in Piombino "Officine Perseveranza", equipped with the first Bessemer converter in Italy.
In 1908 the largest industrial complex already represented the first Italian plant at full cycle for steel making.
Since the beginning, Piombino plant (formerly Lucchini) has remained committed to the steelmaking and has overcome many challenges in Both processing and new market developments.
In the Seventies and Eighties, Piombino plant had widened its product range, investing in R&D sector and developing its internationalization processes.
In 2018 the JSW Group acquired Piombino Plant.
Max lenght: from 27 Kg/m to 75 Kg/m - 108 m unwelded for conventional and high speed lines.
In the railway sector JSW Steel Piombino is the only Italian producer of rails up to 108 meters unwelded.
The rails and railway equipment produced at Piombino have been used by the Italian State Railway for the construction of the whole Italian network since 1909. The continuous modernization of the Piombino production line of rails has allowed the company to reach a leadership position on an international level and to become one of the most important business partners for the delivery of rails and railway equipment.
JSW Steel Piombino also produces Check rail and tongue bars.
Internal diameter: 830-1000 mm
External diameter: 1100-1250 mm
Max. coil weight: 1800-2000 Kg
Diameters: 5.5 - 17 mm
The production ranges from extra low-carbon steels to wire rods for heavy galvanizing with guaranteed silicon content. The different qualities are identified by tensile strength values (N/mm2) and drawing values (reduction percentage).
Applications: Nails, Bright wire incl. for chromium plating, Galvanizing Wire, Wire Gauze, Metal straps and cold rolled special profiles, electro-welded mesh.
The grades proposed are the result of considerable feed-back from the fastern industry with its highly demanding requirements. The wire rod produced in Piombino Plant is suitable for the production of high deforming ratio parts due to its excellent structural homogeneity, low residual level and marked cold formability.
Applications: Extra low-carbon steels for production of low strength parts, Boron and non-boron steels for screws/self tapping screws, Steels for production of high and ultra high strength nuts and bolts.
The high degree of internal purity of the steel and the inherent ductility conferred by Stelmor treatment are factors that satisfy the most demanding requirements of wire manufacturer. In particular the grades are suitable for wire ropes and strands.
Applications: PC Strands, Strands, Lifting ropes, High-carbon mechanical springs, Sitting and Bedding springs, Steel metal straps, Springs for agricultural machines.
The main features of this product are low level of residual elements and high homogeneity of chemical analysis. These properties allow a high drawing of the wire rod and make the end-product particularly suitable for automatic and semi- automatic welding processes.
Applications: Electrodes, Wire for gas-shielded arc welding, Wire for submerged arc welding.
Range: 35-125 mm
Round and 40-100 mm Square
Micro-alloyed steels are created by using small additions of Vanadium, Niobium, Titanium or a combination of the three, instead of Ni, Cr and Mo. During cooling the micro-alloying elements form nitrides, carbides and/or carbonitrides. This treatment increases the strength of the material. An advantage of these steels is that required mechanical properties can be reached without heat treatment. The development of this product is a typical example of cooperation between steel producers and final end users.
Applications: Wheel hubs for industrial vehicles and automotive, Vehicle suspension systems, Hub carrier, Stub-axle.
Boron steels use small additions of boron to increase their hardenability. This process gives steel higher hardness. With this small addition, other elements such as Cr, Ni and Mo can be decreased or eliminated from the steel, making it less expensive without compromising its properties. These steels are suited for heavy machinery, construction, agriculture, mining and other industries.
Applications: Tractor wheels, Wheel chains, Caterpillar tractors, Components for earth moving vehicles, Wheel axles, Hitch.
These steels are usually subjected to a surface hardening process which consists of a case–hardening and temper and are destined to the production of mechanical parts for which it is necessary to increase their surface hardness but leaving a ductile core. This combination of properties is very useful for applications as gears, since it develops an high-impact resistance.
Applications: Vehicle transmission gears, Bevel gears, Mechanical educers for lifts, Wind turbine transmissions.
This group includes those steels which are used for the production, after a suitable quenching and tempering treatment of mechanical parts where they are subjected to particular service stresses. The steel used for the manufacture of this parts can be resulphurized for higher machinability.
Applications: Gear wheels, Crankshafts, Connecting rods for pistons, Universal joints, Cardan shafts, Drag links, Axels shafts.
