The tri-ply stainless steel pressure cooker represents the high-end of pressure cookware, with craftsmanship that combines durability, safety, and versatility. Its core is a three-layer composite structure: 316 stainless steel inner layer (food-grade, corrosion-resistant, and non-toxic), middle aluminum layer (rapid heat conduction, uniform heating), and 304 stainless steel outer layer (high-temperature resistant, scratch-proof, and induction-compatible). The cladding process uses vacuum rolling technology, which bonds the three layers seamlessly, avoiding gaps that cause heat loss or delamination. The pot body is forged with thickened materials, enhancing pressure-bearing capacity—able to withstand high internal pressure without deformation. The sealing ring is made of food-grade silicone, resistant to high temperatures and aging, ensuring long-term airtightness. The safety system includes a pressure limiting valve, floating valve, and explosion-proof window, all tested through rigorous pressure cycling to ensure reliable operation. The inner surface is polished to a mirror finish, easy to clean, and the pot handle is ergonomically designed, heat-insulating and non-slip. This craft integrates the advantages of stainless steel and aluminum, making it durable, safe, and suitable for all cooktops, meeting the needs of high-quality cooking.
