hot-dip aluminum-silicon alloy coating Aluminum silicon coated high-strength low-alloy steel (LA)
In low carbon steel or ultra-low carbon steel, the precipitation of carbon nitrogen compound particles is strengthened by adding single or composite microalloying elements such as niobium, titanium, vanadium, etc. At the same time, the refinement of grain size by microalloying elements can achieve higher strength.
Hot stamping (HS) and press hardening (PH) of aluminum silicon hot stamping forming
Hot stamping forming is a forming technology that heats steel plates above the austenite temperature, quickly transfers them to the stamping machine mold for high-speed stamping forming, and achieves quenching through mold cooling during the holding pressure stage, thereby obtaining the target shape and target strength parts.
Hot Stamping Steel, Press Hardening Steel for Aluminum Silicon Hot Stamping
Hot stamping steel is a type of steel that can achieve different strength levels through a reasonable composition design and the addition of microalloys such as boron and chromium to improve hardenability.
Stretcher strain marks, due to aging, cause uneven deformation of steel plates or strips during cold forming processing, resulting in local plastic deformation of the steel plates or strips. Eventually, a series of parallel linear folds or irregular lines at a certain angle to the stretching direction, irregular surface distortions, and other defects that damage the surface appearance quality will appear on the surface of the steel plates or strips.
Aluminum silicon grade:
DC51D+AS, DD51D+AS, SA1C low carbon steel
DC52D+AS, DC53D+AS, SA1D low carbon steel or gapless atomic steel
DC54D+AS, SA1E gapless atomic steel
HC340LAD+AS, HD340LAD+AS low-alloy high-strength steel
HC950/1300HS+AS,HD950/1300HS+AS,HC340/460HS+AS,HC370/550HS+AS ,HC800/1000HS+AS, HC1100/1700HS+AS
HC1200/1800HS+AS hot stamping steel
ADD51D+AS, HD340LAD+AS, HD950/1300HS+AS are hot-rolled acid washed substrates, while the rest are cold-rolled substrates.
Aluminum silicon plating should ensure that the mechanical properties of steel plates and strips with grades DC51D+AS, DD51D+AS, DC52D+AS, SA1C, and SA1D meet the corresponding regulations within one month from the date of completion of self-made manufacturing; For the steel plates and strips in grades DC53D+AS, DC54D+AS, and SA1E, it should be ensured that the mechanical properties of the steel plates and strips meet the corresponding regulations within 6 months from the date of completion of self-made manufacturing.
