In the previous article (what’s the difference between SUS301 and SUS 304 ), we have a brief introduction about SUS301 and SUS304, the stainless steel materials used in metal dome, which may not be specific enough. Now, let’s use some specific data to deepen the performance between the two material.
1?Material properties between SUS 301 and SUS 304
SUS301: Suitable for elastic use, high carbon content, high hardness, not easy to elastic fatigue, poor ductility, not easy to stretch.
SUS304: Not suitable for elastic use, low carbon content, low hardness (soft)
- If the hardness of the two is close, for example (SUS301 3 / 4H and SUS 304 H), although the hardness is the same, but when they are used in elastic products, SUS 304 H is more likely to produce elastic fatigue.
- The thickness of the material affects the hardness tolerance (the thicker the material, the greater the tolerance)
