Technological breakthroughs and development trends of stainless steel plates

In recent years, technological innovation of stainless steel plates has focused on extreme performance breakthroughs and green production, driving its penetration into high-end fields:
1. Extreme thickness and performance breakthrough
Ultra-thick plate technology: Through processes such as ultra-thick billet production and differential temperature heating, it breaks through the traditional rolling thickness limit (such as achieving mass production of 150mm ultra-thick plates) to meet the requirements of large-scale energy equipment (such as LNG storage tanks and nuclear power pressure vessels) for material strength and low-temperature toughness.
Ultra-thin precision plates: The cold rolling process is upgraded to produce ultra-thin stainless steel plates below 0.1mm, which are used for electronic equipment shielding covers and precision instrument components, and require extremely high dimensional accuracy (tolerance ±0.001mm).
2. Green production and recycling
Short process smelting: Using waste stainless steel as raw material, it is produced through electric arc furnace + refining process to reduce iron ore consumption and carbon emissions (carbon emissions per ton of steel are reduced by more than 50% compared with traditional processes).
Chromium-free passivation technology: Replaces the traditional hexavalent chromium passivation process, reduces heavy metal pollution, and adapts to fields with strict environmental protection requirements (such as food contact materials).
3. Functional innovation
Antibacterial stainless steel plate: Adding copper, silver and other elements to inhibit the growth of bacteria such as Escherichia coli and Staphylococcus aureus, used for walls and equipment in hospitals and food workshops.
Wear-resistant stainless steel plate: Through surface nitriding and shot peening to improve hardness (HV ≥ 500), used in wear-resistant scenarios such as mining machinery and conveying equipment.
