Latest Patents

Pengju Du holds a patent for a steel plate used for hot stamping forming, along with the associated forming process. The patent describes a steel sheet that includes, by weight percent, 0.18–0.42% of carbon (C), 4–8.5% of manganese (Mn), and 0.8–3.0% of silicon (Si) and aluminum (Al), with the balance being iron (Fe) and unavoidable impurities. This unique composition allows the actual measured value of the martensitic transformation start temperature after hot stamping to be ≤280°C. The manufacturing method involves heating the material to a temperature range of 700–850°C, followed by stamping and cooling to a temperature that is 150–260°C below the martensitic transformation start temperature. The resulting components exhibit impressive mechanical properties, including a yield strength of ≥1200 MPa, a tensile strength of ≥1600 MPa, and a total elongation of ≥10%.
