Stainless Steel Spring Temper Strip

1. Product Overview

Stainless Steel Spring Temper Strip is a customized precision stainless steel strip with professional spring toughness and tensile strength. Different from ordinary cold-rolled stainless steel strips, it adopts precise cold rolling and gradient tempering processes to form stable elastic performance, which can maintain consistent mechanical properties under long-term cyclic stress and extreme environmental conditions.

Relying on years of precision metal processing experience, Qihong’s Stainless Steel Spring Temper Strip strictly controls thickness tolerance, surface finish and hardness uniformity in the whole production process. The product covers complete specifications of thickness and width, supports standard finished products and personalized customized processing, and is suitable for manufacturing various high-precision elastic parts that require anti-fatigue, anti-corrosion and high-strength characteristics. As a trustworthy supplier in the stainless steel precision processing industry, we always adhere to quality-oriented production standards to ensure product stability and consistency.

2. Core Product Features & Advantages

2.1 Excellent Mechanical Elasticity

After professional spring tempering treatment, the strip has ultra-high tensile strength and yield strength, with outstanding anti-fatigue performance. It can withstand millions of times of repeated bending, stretching and resetting without deformation or elastic attenuation, fully meeting the long-term stable operation requirements of precision elastic components.

2.2 Superior Corrosion Resistance

Adopting high-quality 200/300/400 series stainless steel raw materials (301, 304, 316L, 430, etc.), the product has excellent rust and corrosion resistance. It can adapt to humid, high-temperature, weak acid and alkali working environments, avoiding rust failure and performance degradation of elastic parts in complex scenarios.

2.3 High Precision & Stable Quality

Supported by advanced cold rolling equipment and professional testing instruments, Qihong realizes micron-level thickness tolerance control for the spring temper strip. The product surface is smooth and flat without scratches, cracks and burrs, with uniform overall hardness, which is convenient for subsequent stamping, bending, cutting and other deep processing.

2.4 Wide Adaptability & Customization

The product supports diversified specification customization, including different thickness, width, hardness and surface treatment processes (brushed, polished, etc.). It can be tailored according to customers’ component design and usage scenarios, covering industrial, electronic, automotive and other multi-field application demands.

3. Main Applicable Materials & Specifications

Qihong’s Stainless Steel Spring Temper Strip covers multiple mainstream stainless steel grades with stable spring performance, meeting different environmental and mechanical performance requirements:

• 301 Stainless Steel: The most widely used spring temper strip material, with high elasticity and fatigue resistance, suitable for high-frequency alternating working conditions of precision elastic parts.
• 304 Stainless Steel: Balances elasticity and corrosion resistance, applicable to daily industrial and electronic components with moderate elastic requirements and high anti-rust demands.
• 316L Stainless Steel: Features ultra-strong corrosion resistance, suitable for marine, chemical and other harsh corrosive environments.
• 430/420 Stainless Steel: High cost performance, with good hardness and wear resistance, suitable for general industrial elastic fasteners and stamping parts.
• Conventional products support thickness 0.05mm–3.0mm and width 5mm–1250mm, and can be customized with special specifications according to customer drawings and samples.

4. Real Application Cases

4.1 Precision Electronic Component Case

A domestic precision electronics enterprise purchased Qihong 301 stainless steel spring temper strip with a thickness of 0.1mm to produce mobile phone dome switches and battery contact shrapnels. The product maintains stable elastic reset performance after 500,000 pressing tests, with no elastic fatigue or surface oxidation. Compared with ordinary stainless steel strips, the product effectively reduces the failure rate of electronic switches by 35%, and has been used for mass production by the enterprise for a long time, with stable batch quality.

4.2 Automotive Precision Fastener Case

An automotive parts manufacturer adopted Qihong 430 spring temper strip to produce automotive interior fixing clips and suspension buffer gaskets. Relying on the product’s high toughness and anti-fatigue performance, the clips can adapt to long-term vibration and temperature changes in automotive driving scenarios, avoiding loosening and failure. After one year of vehicle road test verification, the parts have zero failure, fully meeting automotive industry precision and durability standards.

4.3 Environmental Equipment Accessories Case

A chemical environmental protection enterprise customized 316L stainless steel spring temper strip from Qihong for sewage treatment equipment elastic sealing parts. The product resists the corrosion of weak acid and alkali sewage environments, and maintains stable sealing elasticity under long-term humid working conditions. It solves the problem of easy rust and failure of ordinary spring steel strips in corrosive environments, extending the service life of equipment accessories by more than double.

5. Product FAQ

FAQ 1: What is the difference between stainless steel spring temper strip and ordinary cold-rolled stainless steel strip?

Ordinary cold-rolled stainless steel strips focus on flatness and surface quality, with general elastic recovery and poor anti-fatigue performance. Qihong’s stainless steel spring temper strip is specially tempered on the basis of cold rolling, with strictly controlled hardness and tensile strength. It has professional elastic recovery ability and can withstand long-term repeated bending and vibration without permanent deformation, which is specially designed for elastic component manufacturing scenarios and cannot be replaced by ordinary cold-rolled strips.

FAQ 2: Which steel grade of spring temper strip is suitable for outdoor and corrosive environments?

For conventional outdoor dry environments, 304 stainless steel spring temper strip is the best choice, with balanced cost performance and basic anti-corrosion performance. For humid, salt spray, chemical and other harsh corrosive environments such as coastal and chemical plants, it is recommended to choose 316L stainless steel spring temper strip. Its molybdenum-containing alloy structure greatly improves anti-rust and anti-corrosion ability, ensuring long-term stable service of components in extreme environments.

FAQ 3: Can Qihong provide customized specifications and surface treatment for spring temper strips?

Yes. As a professional manufacturer and processor of precision stainless steel strips, Qihong supports full customized services. We can adjust product thickness, width, hardness and elasticity according to customer design requirements, and provide diversified surface treatments such as brushing, polishing and oil-free cleaning. Meanwhile, we support small-batch trial production and large-batch mass production, and provide professional product parameter test reports to meet customers’ personalized processing and application demands.
