Improvement in Punching Properties of High Tensile

As a result, the center segregation of Mn in high tensile strength steel sheets decreased by the heat-treatment (600 oC for 100 h) with maintaining the tensile strength, the depth of rollover and the burr height. The crack-formation frequency of the steel sheets decreased through heat-treatments. Newly-Developed Ultra-High Tensile Strength Steels with From the beginning of the 1990s, ultra-high strength steel sheets of TS780 MPa grade and higher were stud-ied. Conventionally, this type of ultra-high strength steel sheet had been applied in safety reinforcing parts located away from the cabin, such as bumper reinforc-ing materials, door impact beams, and the like, but in

Prevention of delayed cracking of punched 1.5 GPa ultra

Aug 02, 2020 · The strength of the ultra-high strength steel sheets used for cold stamping attains 1.5 GPa at present , and this strength is the same level as hot-stamped parts made of quenchable 22MnB5 steel sheets . Although hot stamping is major for production of automobile 1.5 GPa steel parts, cold stamping of the ultra-high strength steel sheets has the advantages of high productivity, conventional Prevention of delayed cracking of punched 1.5 GPa ultra strength steel sheets. In punching of ultra-high strength steel sheets, the sheared edge undergoes large shear deformation, and the quality of the sheared edges deteriorates due to early onset of cracks caused for the low ductility, a large rough frac-ture surface [21, 22]. Moreover, a high tensile

Review of Shearing Processes of High Strength Steel Sheets

Jun 07, 2020 · sheets to the body-in-white tends to increase, and moreover the use of ultra-high strength steel sheets having a tensile strength above 1 GPa for reinforcements is expanding. The weight of automobile parts is reduced by downgauging using the high strength steel sheets [1]. S550MC Hot Rolled High Strength Sheets, High Tensile Steel Champak Steel & Engg. Co. is a highly demanded fabricator of S550MC high tensile sheets which is a high-strength, low-alloy steel that is hot-rolled. It has a high strength-to-weight ratio, excellent formability, and reliable consistency.

Surface and interior residual stress analysis of a deep

Jul 13, 2021 · This study examined the residual stresses on the surface and in the interior of a deep-drawn cup made from a 1180-MPa class ultra-high strength steel sheet. A high residual stress causes a delayed material fracture, and an accurate evaluation of residual stress reduces failure risks. Nevertheless, the residual stress in the vicinity of the scratch marks, induced by galling in the Vanadium Microalloying for Ultra-high Strength steel Sheet Oct 04, 2018 · Abstract:Ultra-high strength steel sheets have been subjected to heat treatments that simulate the thermal cycles in hot-dip galvanising and galvannealing processes and evaluated with respect to their resulting mechanical properties and microstructures. The steels contained suitable contents of carbon
