China’s steel industry has made a major advance in ultra-thin steel production. LY Steel and a Jiangsu-based cold-rolled strip manufacturer have jointly achieved a technological breakthrough. They have successfully rolled SK series steel from 1mm down to an extreme thickness of 0.01mm. This establishes China’s first mass production capability for such material, ending a long-standing foreign monopoly.
The success in creating an ultra-thin rolled steel plate relies on superior raw material quality. Three technical strengths enable this achievement. The steel possesses ultra-high purity and uniform microstructure to prevent rolling breaks. It also demonstrates exceptional processing plasticity under massive deformation. Furthermore, it maintains stable mechanical properties across all production batches.
The 0.01mm breakthrough transforms the material’s applications. SK series steel now moves beyond traditional tools into advanced functional components. It enables uses in precision electronics, micro-sensors, and electromagnetic shielding. This opens new markets and drives downstream innovation.
This domestic achievement offers significant practical advantages. It provides reliable local supply with competitive pricing and faster response. Customer dependency and costs are effectively reduced. The accomplishment demonstrates China’s growing technological self-reliance in advanced materials.
Beyond the flagship SK series, LY produces various tool steels like 75Cr1 and GCr15. All maintain consistent quality and volume supply. The mass production of this ultra-thin rolled steel plate combines innovation with strong manufacturing capability. It positions Chinese materials for more demanding global applications.
