Pickled Automotive Steel
Pickled automotive steel is a type of steel that has undergone pickling treatment and is mainly
used in the automotive manufacturing industry. The main purpose of acid washing treatment is to
remove the oxide scale and impurities on the surface of steel, and improve the surface quality
and processing performance of steel. Pickled automotive steel typically follows strict European
standards such as EN 10111 and DD11. This type of steel has superior mechanical and processing
properties and is suitable for the manufacturing of automotive components.
Application fields of acid washed automotive steel
Pickled automotive steel is widely used in the automotive manufacturing industry, mainly for
manufacturing structural components, parts, and accessories of automobiles.
For example:
Sturdy frame:
Pickled automotive steel has good strength and corrosion resistance,
suitable for manufacturing car frames and other structural components.
Flexible suspension system:
Its excellent processing performance makes the manufacturing of suspension
systems more precise and reliable.
Body panels:
High surface quality, suitable for manufacturing body panels, enhancing the
overall appearance and durability of vehicles.
The role of pickling process
The pickling process plays a crucial role in the production of pickling automotive steel.
Through acid washing, the oxide scale and impurities on the surface of the steel can be
thoroughly removed, improving the surface smoothness and roughness of the steel, thereby
enhancing its welding performance and corrosion resistance. In addition, the pickling process
can provide a layer of protection for steel, ensuring its stability even in harsh environments.
Main grades of acid washed automotive steel
S315MC:
Cold formed hot-rolled pickled automotive structural steel produced by Baosteel, with good
cold formability, used for structural components such as automotive beams and crossbeams.
QSTE380TM:
Cold formed hot-rolled acid washed automotive structural steel produced by
Baosteel, suitable for automotive structural components that require high strength.
QSTE500TM:
Cold formed hot-rolled acid washed automotive structural steel produced by
Baosteel, with a tensile strength of 550-700MPa and a yield strength of ≥ 500MPa.
Other common pickled automotive steel grades
SAPH310, SAPH370, SAPH400, SAPH440, SPFH540, SPFH590: These grades of high-strength steel are
used for automotive structural components.
QSTE340TM, QSTE420TM, QSTE460TM, QSTE550TM, QSTE600TM, QSTE650TM, QSTE700TM: These grades of
steel are mainly used for high-strength automotive structural components.
S355MC, S420MC, S460MC, S500MC, S550MC, S650MC, S700MC: These grades of steel also belong to the
SMC series and are used for various automotive structural components.
QStE340TM, QStE420TM: These grades of steel are also commonly used in automotive structural
components.
In summary, acid washed automotive steel plays an important role in the automotive manufacturing
industry, and its superior performance and processing characteristics make it an ideal material
for manufacturing high-quality automotive components.
