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. As a widely used austenitic stainless steel elastic material, this product, processed with Qihong's precision technology, retains the acid and alkali resistance and salt spray resistance characteristics of the 304 material itself, while also possessing stable resilience and long fatigue life. It can accurately meet the manufacturing needs of precision components in various fields such as electronics, automobiles, medical equipment, and industrial machinery, making it a high-quality elastic material choice that balances performance and reliability.
