Ningbo Qihong Stainless Steel specializes in precision stainless steel processing and manufacturing. With advanced technical equipment, a scientific management system, and professional testing capabilities, we provide high-quality stainless steel spring strips to various industries. We understand the high standards required for materials in precision manufacturing and demanding working conditions. This stainless steel spring strip is a core product developed based on our years of industry experience, offering both stable performance and adaptability, helping our customers enhance the competitiveness of their end products.

qihong 0.01mm Stainless Steel Foil is an ultra-thin cold-rolled stainless steel material supplied for precision stamping, narrow-width components, shielding parts, sensors and other industrial applications requiring a 0.01mm gauge. Multiple grades, tempers, surface finishes, edge conditions and slit widths are available according to the required material specification.

As a professional stainless steel material supplier, Qihong's 301 stainless steel foil is meticulously crafted through a precision cold rolling process, with a thickness range of 0.02-0.3mm. Among them, the ultra-thin specifications can reach the "tearable steel" level, making it a core material for lightweight and miniaturized designs in the high-end manufacturing field. It has gained widespread recognition and favor from customers in various industries over the years.

Hardened stainless steel spring strip is a cold-rolled tough steel material. It is mostly made for elastic parts that bend repeatedly. Located in Ningbo, we temper every steel coil in stable production conditions. This keeps steady hardness, good bending performance and longer fatigue life. Compared with ordinary stainless strips, our hardened steel maintains good elasticity under continuous force. It is a trustworthy material for precision shrapnel and small spring components. We have complete in-house rolling lines and testing machines. Every production batch is checked carefully on dimension, surface condition and hardness. We never use low-grade raw materials to cut costs. For us, stable quality and high precision always come first for industrial buyers.

Ningbo Qihong Stainless Steel focuses on the research and manufacturing of high-strength stainless steel strips. Leveraging years of precision machining experience and a complete supply chain system, we have created martensitic hardened stainless steel strips that meet the high-end needs of various industries. Our Hardened Stainless Steel Strip is based on high-quality materials such as 420 (3Cr13), 440A, and 440B, and is meticulously crafted using our proprietary and mature quenching and tempering heat treatment process. It combines high hardness, wear resistance, and basic corrosion resistance, precisely matching the core component manufacturing needs of medical devices, precision electronics, high-end cutting tools, and other fields, providing customers with highly stable and adaptable precision material support.

High Strength Stainless Steel Foil from Qihong covers 301, 304 and 316L in 0.01-0.30 mm thickness and 1.5-600 mm slit width, in 1/2H to H temper for springs and shielding. The Ningbo manufacturer rolls and slits in house, with a test certificate on every batch.
