SUMMARY:

The monobloc forged tubular beams, manufactured of seamless steel tubes in Brazil, are feasible due to the current Exchange rate and high costs of importation of competitive axle beams. The search for competitiveness of national products is necessary to guarantee the growth and strength of our transformation industry. This work consists on the characterization of forged seamless steel tubes of the steel grade FB70 without the final normalization heat
treatment processo simplify the manufacturing process. The approval of the axle beams without the heat treatment was done upon laboratory tests for the mechanical properties to guarantee the engineering specifications. The results of the yield strength of 490 MPa, the tensile strength of 610 MPa, alongation of 20% and Rockwell B hardness of 87 HRB were fully attended based on a typical cooling curve, as well as the fatigue test.
