Hot-rolled steel for one-surface enamelling

Thanks to a concept of analysis related to specific rolling parameters, this type of material is suitable for ONE SURFACE enamelling. Prior to an industrial use, we recommend a test batch because the surface quality to be obtained is influenced not only by the material but also by the pre-treatment and the type of enamel used.

Hot-rolled steel with high yield strength for cold forming

Standard of reference UNI-EN 10149-2 thermo-mechanical steels (more generally known and used) oe UNI-EN 10149-3 standardised steel State of supply NOT-PICKLED (black) or PICKLED High tensile steel, micro-alloyed with guaranteed minimum yield strength: they are excellent for welding and cold forming. The qualities are identified by the minimum guaranteed yield strength. The high mechanical characteristics of this range of steels and the good drawing qualities allow to create cost-effective solutions for several parts or details that require reductions in weight, thickness and overall dimensions, while leaving unchanged the resistance of parts or details. Some examples of application can be: highway trailer trucks, buckets, large trucks, cranes, farm equipment, beams, welded tubes, profiles in general for scaffolds or shelves, containers, guide bars, street lamps. The regularity of the spring back makes this steel suitable for all automated mass productions and also facilitates the assembly. Qualities that can be supplied S315MC – S355MC – S420MC – S260NC – S315NC – S355NC – S420NC Exaples of...

Hot-rolled steel for structural applications

Standard of reference UNI-EN 100025 State of supply NOT-PICKLED (black) or PICKLED Structural steel, consisting of 4 levels identified by the guaranteed minimum yield strength. Each level consists in turn of different qualities depending on the characteristics of impact strength KV and the state of supply. These steels are suitable for various applications in general construction and in the manufacture of parts that have to withstand severe stresses. According to the minimum yield strength, the most suitable material can be identified depending on the end use. For high yield strengths related to other formability performances, it is necessary to move towards high tensile micro-alloyed steels. S185 Basic steel S235 Equipment not requiring lightening and not subjected to severe stress. Quality fit for parts with medium difficulty. S275 Operating parts subjected to average level stresses: section bars, welded beams, tanks. S355 Fixed or mobile details, metal structures that need to withstand heavy stresses: street lamps, trailer chassis, equipment for public works. Examples of...
