摘要: The invention relates to a method for manufacturing a ferritic-austenitic stainless steel having good formability, good weldability and high elongation. The stainless steel containing the sum of carbon and nitrogen C+N in the range 0.17-0.295 in weight % in which sum C+N a lower carbon content to avoid sensitisation during welding is compensated by an increased nitrogen content to maintain formability is heat treated so that the microstructure of the stainless steel contains 45-75% austenite in the heat treated condition, the remaining microstructure being ferrite, and the measured Md30 temperature of the stainless steel is adjusted between 0 and 50° C. in order to utilize the transformation induced plasticity (TRIP) for improving the formability of the stainless steel.

摘要: The invention relates to a method for manufacturing a sandwich panel as a semi-finished product where at least one layer of a non-metallic material is positioned (4) between at least two metallic layers (1,2,5). At least one of the metal layers is shaped into a three dimensional layer (2), and the metal layers (1,2,5) are material closured to each other by a tack weld (3,8) on the metallic contacts between the metallic layers (1,2,5) to enable resistance weldability of the semi-finished product in order to connect the semi-finished product to a desired combination of solutions.

摘要: 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 R p0.2 , tensile strength R m 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.
