Stud Bolt Material Properties and Selection Guide

Understand the characteristics of each material and choose the optimal stud bolt.
Stud bolts are essential components for machine assembly and securing building structures. Various materials such as steel, stainless steel, brass, titanium, and aluminum are used, each with unique characteristics and applications. This article explains the characteristics of each of these materials and when to appropriately select them.
■Features
Steel: Offers excellent strength and durability, along with superior cost performance. It is widely used for general machine parts and construction materials, but has the drawback of being prone to rust.
Stainless Steel: Possesses high corrosion resistance and combines it with strength. It is suitable for medical devices and food processing machinery where hygiene and cleanliness are required, as well as for structures in coastal areas.
Brass: Has good electrical conductivity and corrosion resistance, and its aesthetic appeal makes it suitable for decorative items, electrical components, and plumbing-related parts.
Titanium: Lightweight, extremely high strength, and excellent corrosion resistance. It is frequently used in the aerospace industry and medical devices.
Aluminum: Lightweight yet possesses moderate strength and excellent corrosion resistance. It is used in automotive and aircraft parts, and construction materials.
■Selection Guidelines
When selecting stud bolts, it is necessary to consider the operating environment (e.g., high corrosivity, required strength), necessary mechanical properties (durability, heat resistance), cost, and the aesthetic requirements of the final product. For example, if aesthetic appeal and corrosion resistance are required, brass or stainless steel are chosen, whereas titanium is suitable when high strength and heat resistance are necessary. Furthermore, if the goal is overall cost reduction, steel or aluminum are preferred.
By understanding the unique characteristics of each material and appropriately selecting stud bolts, you can maximize product performance. Proper material selection significantly impacts product durability, safety, and cost efficiency.
