Hotform Tailored Blanks  

Tailored Blanks for Hotforming  

Crash safety meets lightweight construction: During hot forming, the blank is heated and then shaped and quenched in a tool. This achieves strengths of 1500 MPa or more– a property that has decisively advanced the possibilities of automotive lightweight construction. This is because components with the same or even improved crash performance can be designed with thinner material. 

The use of Hotform Blanks makes it possible to weld individual sheets of different thicknesses together. In addition, the manganese-boron steel can be combined with other steel grades, such as with more ductile or cheaper materials. This guarantees maximum strength and high functionality with the smallest possible weight. 

Welding with and without coating.

Manganese boron steels have a surface coating of aluminium and silicon. This layer is usually removed locally before welding. Baosteel Lasertechnik GmbH has built machines for this process since 2013. 

Several years ago, a more sustainable production method has been developed. We now can weld without decoating, safely and sustainably, saving considerable costs. Machines with this special process are running worldwide in serial production. Existing machines can also be upgraded to use this process.

Baosteel Lasertechnik GmbH offers a wide range of machine concepts for the production of Hotform Tailored Blanks.
