Model 201 Stainless Steel Wire 40-45x3 Dia|High-Strength Spring Material|Fastener Component|Corrosion-Resistant Alloy

Type 201 Spring
3mm Stainless Spring
Grade 40-45 Spring Wire
201 material 40-45*3 [wire diameter]
Type 201 Spring crafted from Grade 40-45 stainless steel spring wire, offering 3mm diameter for optimal durability and performance in demanding applications. Ideal for precision engineering with high-strength 3mm stainless spring characteristics.

Product Description

The Type 201 Spring, crafted from durable 3mm Stainless Spring wire, is manufactured using high-grade Grade 40-45 Spring Wire for exceptional tensile strength and corrosion resistance. Designed for industrial applications such as automotive systems, heavy machinery, and aerospace components, this spring operates reliably within a temperature range of -50°C to 250°C. Its compact 3mm diameter and precision engineering enable consistent load distribution and long-term durability in high-stress environments. Key advantages include minimal maintenance, vibration damping, and resistance to chemical exposure, though it may require periodic lubrication in extreme conditions. The spring supports direct integration into modular assemblies and is commonly used in valve mechanisms, sensor actuators, and precision equipment requiring controlled elastic force.
