Ningbo Qihong has been supplying precision stainless steel strips for many years. We have complete, readily available equipment, experienced workers, and reliable technicians. We specialize in producing thin stainless steel spring strips. Our raw materials are carefully selected high-quality stainless steels such as SUS301, SUS304, and SUS316. We meticulously process each step, from cold rolling to heat treatment, without cutting corners. Our steel strips are extremely thin, ranging from 0.03mm to 0.5mm, almost at the micron level. They offer excellent precision, elasticity, and rust resistance, making us one of the best in the industry. Our production adheres to international standards such as ASTM, JIS, and GB, making them suitable for industries like consumer electronics and new energy. The products we deliver to our customers are durable, reliable, and flexible materials.

Ningbo Qihong Stainless Steel, deeply rooted in the field of precision stainless steel processing and manufacturing, leverages its mature production system, sophisticated processing equipment, and professional technical team to create Precision Stainless Steel Spring Strips suitable for high-end fields such as precision electronics and new energy. The products use austenitic stainless steel such as SUS301, SUS304, and SUS316 as core base materials, integrating core processes such as precision rolling, bright annealing, and tension leveling to achieve a dual breakthrough in micron-level precision control and excellent elastic performance. Thickness tolerance, flatness, and hardness uniformity all meet high industry standards. Produced in strict accordance with international standards such as GB, ASTM, and JIS, the products can fully meet the manufacturing needs of lightweight, miniaturized, and highly integrated components, providing highly reliable elastic material solutions for precision components in various fields.

Ningbo Qihong Stainless Steel Co., Ltd. has been manufacturing 301 stainless steel spring strips for many years, consistently adhering to material standards such as SUS301, AISI 301, and 1Cr17Ni7, and complying with international specifications such as ASTM A666 and JIS G4313. Leveraging the advantages of Ningbo's concentrated precision stainless steel industry and our years of experience in steel strip processing, we have equipped ourselves with imported production equipment and a full range of testing instruments. We can reliably produce strips in thicknesses from 0.03 to 3.0 mm and widths from 3 to 600 mm, with hardness levels ranging from 1/2H to SH. We offer both stock and custom-made products to meet customer needs. We also handle precision slitting and non-standard sizes. This strip hardens quickly after cold working and maintains stable elasticity. We are currently supplying this product in bulk to industries such as consumer electronics and automotive manufacturing. We offer competitive pricing, provide authoritative material certificates with every batch, and guarantee timely delivery and quality.

High quality 304 stainless steel spring strip is one of the core precision strip products of Ningbo Qihong Stainless Steel Co., Ltd. Leveraging the company's extensive experience in stainless steel processing and manufacturing, as well as its sophisticated cold rolling and heat treatment equipment and professional testing system, this product is specifically designed for applications with stringent requirements for elasticity, corrosion resistance, and dimensional accuracy.
