    Abstract: The invention relates for a method for partial hardening of an austenitic steel by utilizing during cold deformation the TWIP (Twinning Induced Plasticity), TWIP/TRIP or TRIP (Transformation Induced Plasticity) hardening effect. Cold deformation is carried out by cold rolling on at least one surface (2,3;12) of the material (1,11) to be deformed with forming degree (Φ) at the range of 5 ≤ Φ ≤ 60 % in order to achieve in the material (1,11) at least two consecutive areas (5,7;14,16) with different mechanical values in thickness, yield strength Rp0.2, tensile strength Rm and elongation having a ratio (r) between ultimate load ratio ΔF and the thickness ratio Δt at the range of 1.0 > r > 2.0, and which areas are mechanically achieved to connect to each other by a transition area (6;15) which thickness is achieved variable from the thickness (t1,t3) of the first area (5,14) in the deformation direction (4,13) to the thickness (t2,t4) of the second area (7,16) in the deformation direction (4,13). The invention also relates to the use of the cold deformed product.

    Abstract: The invention relates to a method for manufacturing a welded component, where at least one material piece is positioned between metal pieces to be welded together. At least one protrusion (5, 13, 23, 33, 43) is achieved to at least one of the metal pieces (3, 4; 11, 12; 21, 22; 31, 32; 41, 42) to be welded together, and at least one opening (2, 14, 24, 34, 44) is achieved to at least one material piece (1, 15, 25, 35, 45) which is positioned between the metal pieces (3, 4; 11, 12; 21, 22; 31, 32; 41, 42) to be welded and isolated (16, 17; 26; 36) from the metal pieces to be welded. At least one part of the protrusion (5, 13, 23, 33, 43) in one of those metal pieces to be welded together is taken through the opening (2, 14, 24, 34, 44) in order to have mechanical contact through the upper end of the protrusion (5, 13, 23, 33, 43) with the second metal piece to be welded. Welding (37, 38, 39) of the metal pieces together is carried out by focusing the weld effect to the surface of the second metal piece which is in connection with the protrusion to the first metal piece to be welded. The invention also relates to the use of the component.
