With top-level global technology, strict quality control practices and service know-how
powered by an extensive global network, POSCO delivers top-quality automotive
materials to many global automakers around the world.
A vehicle consists of the body where people and cargo are carried and the chassis where devices required for the vehicle to drive. Our steel intended for vehicles provides different properties in terms of hardness, workability, weldability, corrosion resistance, formability, paintability and linearity, depending on where it is used in the vehicle. With recently ever-tightening environmental regulations, electric vehicles (EVs) and hydrogen fuel-cell vehicles (HFCVs) are emerging as alternatives to internal combustion engine vehicles. EVs are motor and battery of performance is essential, and hydrogen fuel the performance of hydrogen fuel cell is important. With excellent hardness, workability, weldability, corrosion resistance, formability, paintability and distincness of image gloss, POSCO's automotive steel is supplied only with quality products through a thorough quality certification process.

It maintains underbody stiffness. It is connected behind front side member to absorb and transmit collision energy in front/offset collision and requires local stiffness and durability.
Mainly applied steel sheet has a tensile strength of 590~980MPa.
However, steel which has maximum TS 1180MPa is recommended for lighter weight and better collision safety.
The manufacturing process is mainly applied to Forming, Drawing or Roll forming.

980DP | Uncoated, Galvanized, Galvannealed |
1470HPF | Uncoated, Al-Si, Galvanized |
This component connects members with the body and requires sufficient strength of the cross section. The reinforcement back upper front requires sufficient mounting strength as a seat belt reactor can be connected while the reinforcement back upper rear requires sufficient torsional rigidity as it bears an interface with the rear window of the car.
Mainly applied steel sheet has a tensile strength of 260-590Mpa and a thickness of 0.7-1.2mm.The manufacturing process is mainly applied to Drawing or Forming.

780DP | UUncoated, Galvanized, Galvannealed |
CQ | Uncoated, Electrogalvanized, Galvanized, Galvannealed |
340R | Uncoated, Electrogalvanized, Galvanized, Galvannealed |
This component constitutes the structure of a motor vehicle and requires a high level of strength as it has to protect occupants upon side impact. When used inside, it also requires high mounting strength as a seat belt is attached at the top while a seat belt retractor is attached at the bottom. In addition, the reinforcement center pillar also requires high mounting rigidity and strength as a rear door hinge is attached to it.
Mainly applied steel sheet has a tensile strength of 440-980Mpa and a thickness of 0.9-1.8mm.The manufacturing process is mainly applied to Drawing, forming or Tailor welding blanking.

1180TRIP | Uncoated, Electrogalvanized, Galvanized, Galvannealed |
1470HPF | Uncoated, Al-Si, Galvanized |
This component constitutes the structure of a motor vehicle and requires high strength as it has to absorb some of the shocks upon frontal or offset impact and transmit the rest to the side sill and the A-pillar. It also requires appropriate thickness because the cross section that it forms along with A-pillar lower inner determines the rigidity of the body (torsion, bending). It also requires high strength and rigidity at the location where the front door hinge is attached.
Mainly applied steel sheet has a tensile strength of 340-590Mpa and a thickness of 1.2-1.6mm.
