Deformation-hardened component made of galvanized steel, production method therefor and method for producing a steel strip suitable for the deformation-hardening of components

A deformation-hardened component is made of galvanized steel by cutting a plate from a steel strip or steel sheet coated with zinc or with a zinc-based alloy and subsequently heating the plate to a deformation temperature above ac3 for deformation and hardening. The galvanized steel has an at least partially martensitic transformation structure and includes as a chemical composition in wt. ... Salzgitter Flachstahl Gmbh

High-strength air-hardening multi-phase steel comprising outstanding processing properties and method for the production of a steel strip from said steel

A high-strength air-hardenable multiphase steel having minimal tensile strengths in a non air hardened state of 750 mpa and excellent processing properties includes the following elements in % by weight: c≧0.075 to ≦0.115; si≧0.600 to ≦0.750; mn≧1.000 to ≦1.950; cr≧0.200 to ≦0.600; al≧0.010 to ≦0.060; n≧0.0020 to ≦0.0120; s≦0.0030; mo≧0.0200; nb≧0.005 to ≦0.040; ti≧0.005 to ≦0.030; b≧0.0005 to ≦0.0030; ca≧0.0005 to ≦0.0060; cu≦0.050; ni≦0.050; remainder iron, including usual steel accompanying smelting related impurities, wherein for a widest possible process window during continuous annealing of hot strips or cold strips made from the steel a sum content of m+si+cr+mo in the steel strips is a function of a thickness of the steel strips according to the following relationship: for strip thicknesses of up to 1.00 mm the sum content of m+si+cr+mo is ≧2.450 and ≦2.800%, for strip thicknesses of over 1.00 to 2.00 mm the sum of mn+si+cr+mo is ≧2.600 and ≦3.150%, and for strip thicknesses of over 2.00 mm the sum of mn+si+cr+mo is ≧3.000 and ≦3.450%.. . ...

Method for producing a component by subjecting a sheet bar of steel to a forming process

A method for producing a component by forming a plate from steel at room temperature having a high formability and reduced crack sensitivity of edges that have been mechanically cut or punched on the plate, includes: cutting the plate from a strip or metal sheet at room temperature; heating edge regions of the plate that underwent strain hardening as a result of the cutting step to a temperature of at least 600° c. For a time period of at most 10 seconds; and forming the plate in one or more steps into a component at room temperature, wherein in the forming step the edge regions heated in the heating step are subjected to cold forming.. ...
