ArcelorMittal launches S390 EK, a green, cost-effective solution for silos and tanks
17 April 2015 - ArcelorMittal has launched its new high-strength steel grade S390 EK, an innovative, competitive and environmentally friendly solution for the manufacture of silos and tanks. Unlike any other product currently on the market, S390 EK includes two-side enamelling to avoid fish-scaling, thus eliminating the need for specific surface treatments or doped ground enamel, while demonstrating high mechanical properties after enamel firing to withstand load pressure in the silo.
Lower manufacturing costs
S390 EK provides a cost-effective alternative to conventional high-strength steels, which require costly post-treatment to reduce fish-scale appearance. Laboratory tests have shown that S390 EK allows for a reduction of up to 19% in silo manufacturing costs, made possible through a reduction in steel thickness, ground enamel and process cost.
Thanks to its specific chemistry, S390 EK offers silo and tank manufacturers a sustainable solution combining high-strength steel properties with two-sided enamelling. Unlike other high-strength steel solutions, S390 EK does not require the use of ground enamels or sublayers containing metal oxides like NiO and CoO, which cause residual soil pollution and are likely to be phased out under new environmental regulations.
390 MPa minimum yield strength guarantee
As its name suggests, S390 EK has been designed to guarantee a minimum yield strength of 390 MPa after first enamel firing, achieving typical values of around 420 MPa. To achieve such high mechanical properties, the yield strength at delivery stage is generally higher than 620 MPa. With S390 EK, it is no longer necessary to compensate for the inevitable huge drop in mechanical properties after enamelling with expensive ultra-high strength solutions.
Silos and storage tanks made with S390 EK can be used both outdoors and indoors. S390 EK is available as hot rolled coil and sheet in both non-pickled and pickled/unoiled format and is fully compatible with all commonly used enamelling processes, thus requiring no adaptation.
