Selected Materials For High Performance Fasteners: A Guide To Selecting High Strength Screws

Carbon steel: As a widely used high-strength screw material, carbon steel is known for its superior cost performance, especially suitable for applications with strength requirements not exceeding the tenth level. Despite its excellent strength and hardness, its lower toughness means it may break when subjected to severe impacts.
High performance alloy steel: This type of steel, with excellent wear resistance and high levels of tensile strength, works stably in extreme temperature environments and is the preferred choice for high-strength tasks exceeding level ten. However, high performance comes with relatively high costs.
Corrosion resistant stainless steel: In marine engineering, medical equipment, and food manufacturing industries, high-strength stainless steel screws have excellent corrosion resistance, which can effectively resist rust and maintain long-term durability. In addition, its good formability and antioxidant properties are also reasons for its popularity.
Titanium alloy: In the aerospace and aviation industry, high-strength screws made of titanium alloy are highly favored due to their lightweight, high strength, low hardness, high temperature resistance, and excellent corrosion resistance. Despite the complexity and high cost of processing, it performs poorly under extreme conditions.
Taking into account the working environment of screws, such as extreme temperature tolerance, specific corrosion resistance requirements, as well as their plasticity, impact toughness, and ability to prevent delayed fracture, is an important step in material selection. Based on the grade and specific performance standards of screws, precise selection of material models can maximize the utilization of material advantages, ensuring that the high-strength screws produced can meet strict standard requirements in all aspects of performance.
