STANDARD COLD-DRAWN STEEL-BARS
The COLD-DRAWN PRODUCTS offered by Trafital are obtained by processing from rolls or bars. Flat and square drawn products are normally supplied with sharp edges and in their natural state, it is also possible to supply the products with specific heat treatment of stress relief, annealing, normalization and quenched and tempered condition . The commercial length of the bars is 3 or 6 m and fixed lengths can be supplied upon request. Trafital offers the possibility of supplying special profiles, rounded, rounded and shaped. The carbon steels normally available are structural or construction types, free-cutting steels and tempered steels. On request it is possible to supply the bars in other steel qualities. Some of the steels available for flat, square, round and hexagonal drawn plates: Structural or construction steels: S235JR / S275JR / S355J2 Free cutting steels: 11SMn30 / 11SMn37 / 11SMnPb30 / 11SMnPb37 Tempered steels: C45 / 39NiCrMo3 / 42CrMo4 On request it is possible to supply the drawn bars in other steel qualities.
