Hot-rolled steel Next Level: hot-rolled Q
Steel strip individualized to meet customer requirements
Under the ultralights brand, hot-rolled drive, voestalpine provides a range of special hot-rolled steels for the automotive industry. Your advantage: This means that even complex component geometries and forming requirements can be achieved by cold-formed steels.
Hot-rolled Q made by voestalpine offers a previously unattained level of individualized hot-rolled strip and meets even the most precise component requirements of our customers.
Hot-rolled steels for cold forming
Hot-rolled steels made by voestalpine stand for economical and high-quality production and are recommended for a wide variety of applications:
- Chassis, seat components and crash-relevant structural parts made of high-strength steels
- Stabilizers and gas cylinders made of case-hardening and heat-treatable steels
Properties required by the customer
High-precision production operations make it possible to precisely adjust product properties to meet individual customer requirements. Customizable parameters include the following:
Narrowest thickness tolerances
Hot-rolled Q enables the narrowest thickness tolerances up to one sixth of the standard, and these tolerance values are guaranteed across the entire width and length of the strip. Uniformly thick or thin strip runs smoothly through processing operations, protects production equipment and contributes to process reliability as well as cost efficiency.
Uniform profiling
A perfect profile enables the material to be processed without any problems in the long term. Higher production reliability and fewer rejects are the foundation for increased productivity that is always economical in the end. Choose hot-rolled Q with a profile that meets your requirements:
| BASIC Class | ADVANCED Class* | ULTIMATE Class* |
| Norm (EN 10051) | Norm (EN 10051) >= 60µm | narrowest possible 59-30µm |
*Commitment in consultation with technical account manager
Minimum sulfur content
Lower sulfur content means better formability of the material and a perfect edge in the punching process. Greater hole expansion capacity allows greater throughput rates and narrower radii. The pipe industry in particular benefits enormously from improved welding in the radius area of sharp edges. Make your selection based on your requirements.
| BASIC Class | ADVANCED Class* | ULTIMATE Class* | |
| >0.012% |
| <=0.007% |
*Commitment in consultation with technical account manager
Perfect surface
A perfect surface for each application increases the value and quality of each product. The result is less scrap when starting materials feature perfect surfaces, and this means that reworking steps can be eliminated.
Low grain boundary oxidation
Narrowest radii and best deep-drawing properties with maximum resistance to cracking. Low grain boundary oxidation results in a reduced need for post-treatment and potential savings in production.
Minimum decarburization
Minimized decarbonization in the edge area results in optimized surface hardenability. This leads to higher production reliability, thus making production processes efficient and perfectly plannable.
High degree of spheroidization
The high degree of spheroidization makes it possible to achieve the best forming and punching properties. The result is the elimination of a time-consuming production step. The products supplied are based precisely on customer specifications.
