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
