摘要:
A method of producing a structure support may include: providing a hollow workpiece composed of a steel material; heating the hollow workpiece to an austenitizing temperature range to provide the steel material with an austenitic microstructure; forming the hollow workpiece into a predefined complex geometry while the hollow workpiece is still in the austenitizing temperature range; and cooling the hollow workpiece with the predefined complex geometry to transform the austenitic microstructure into a martensitic microstructure.
摘要:
A support may include a hollow metallic tube having two opposing ends and a body extending over a longitudinal axis of the tube. The tube may have a steel composition that may include, by weight, the following concentrations: approximately 0.19 to 0.27% carbon; approximately 0.0005% to 0.004% boron; approximately 1.5% to 2.5% manganese; and less than or equal to approximately 0.35% chromium, the balance including iron and inevitable impurities.

摘要:
A method of producing a shaped structure support, e.g., for a vehicle, is disclosed. The method includes: heating a hollow workpiece of a steel material to a material transformation temperature range; deforming the hollow workpiece in a press into the shaped structure support having a predefined complex geometry while the hollow workpiece is in the material transformation temperature range; and quenching the hollow workpiece through contact with a press tool of the press to provide the shaped structure support with a martensitic microstructure.
