Recently, SCPG Vanadium Titanium Steel Technology Corporation has realized the industrial production of 1.8 mm ultra-thin 1000 MPa ultra-high-strength steel carriage plates, marking a new height in the research and development of SCPG hot-rolled ultra-high-strength steel.
Ultra-high-strength automobile structural parts are the key to realizing automobile lightweight, and automobile lightweight is an important part of the national "carbon peak" and "carbon neutral" strategy. In order to adapt to the development trend of upgrading and lightweighting of steel for commercial vehicles in recent years, Panzhihua Iron and Steel has carried out EVI early intervention in response to the lightweight needs of users, designed lightweight solutions for commercial vehicles, and took the lead in breaking through the hot strip production 1.8 The technological bottleneck of ultra-high-strength steel carriage plates of millimeter ultra-thin 1000 MPa grade. SCPG adopts multi-element microalloying design and TMCP controlled rolling and cooling process control, and successfully developed ultra-thin hot-rolled ultra-high-strength steel with a thickness of 1.8 mm, with a tensile strength of 1000 MPa, mechanical properties, plate shape, dimensional accuracy, etc. The indicators meet the technical requirements and have broad application prospects in the fields of automobile structure and engineering machinery.
SCPG realizes industrialized production of hot-rolled ultra-high-strength steel represented by ultra-thin 1.8mm ultra-thin 1000 MPa ultra-high-strength steel compartment plates, which not only adapts to the lightweight development direction of commercial vehicles, realizes energy saving and emission reduction, and promotes the upgrading of the domestic automobile industry. The replacement has also effectively promoted the efficient batch application of vanadium and titanium resources in steel.
