For most mechanical components, SUS304 and SUS316 can satisfy the majority of requirements. As a result, many people assume: "As long as it's stainless steel, it should be good enough." However, in certain advanced equipment and demanding environments, engineers often discover that even stainless steel components can still suffer from: High-temperature deformation Loss of strength Corrosion failure Long-term fatigue damage Chemical attack At this point, material selection is

Screws When people choose screws, they usually look at size, thread pitch, and head type first.But in real applications, what truly determines whether a screw will fail is often the material. Rust, stripped threads, breakage, deformation, or loosening over time—many of these issues are not caused by poor machining, but by choosing the wrong material from the start. --- 1. Why Does Screw Material Matter So Much? In use, a screw typically faces multiple factors at the same time
