DetailsStraightness
It is the property of long products and indicates the alignment with the axial axis. In bars and specially in cold drawn products, the straightness tolerance is of vital importance, since for later transformations of these products in automatic machines bars with high straightness properties are needed to avoid vibrations and stoppages. The straightness property…
DetailsStress relief
Heat treatment intended to relieve the stress in a material that has been previously rolled.
DetailsSulphur
Chemical element that in the steel forms iron sulfides. It is used as an addition element in free- cutting steels (up to 0.40% by weight) for the formation of manganese sulphides, which favor chip removal and lubricate the tool during machining, improving the speed and durability of the cutting tool.
DetailsSuperficial defect
Discontinuity of depth not allowed according to the standard that applies to the producto to the specification agreed with the customer. Typical defects in steel are cracks, laps, seams and fleck scale. Depending on the severity of the imperfections, certaing defects can include mark and scratches.
DetailsSurface treatment
It is a manufacturing process that is performed to provide certain properties to the surface of a steel. The most common surface heat treatments are case-hardening, carbonitriding and quenching by induction.
DetailsTempering
Complementary heat treatment to quenching that is performed to increase the toughness in detriment of reducing the hardness, resistance and yield strength after quenching. The internal tensions produced in the quenching are also diminished, the structure is homogenized and the final properties required by the piece in service are achieved. It consists of a heating…
DetailsTenacity
It is the ability of a material to absorb energy while being deformed before breaking. In every piece, prior to breaking or fracture, a pre-cracking phenomenon occurs, hence toughness is defined as the resistance to crack propagation of the material. The toughness obtained ina a piece will depend on the chemical composition, the forming processes…
