- 密度: Indicates how much mass is contained in a given volume. This affects the weight of the final product and its applicability in structural applications.
- 融点: The temperature at which the material transitions from solid to liquid. Higher melting points indicate better performance in high-temperature applications.
- 降伏強度: The stress at which a material begins to deform plastically. This property is crucial for determining how much load a structure can support without permanent deformation.
- 抗張力: The maximum stress a material can withstand while being stretched or pulled before breaking. It is essential for assessing material durability under load.
- 伸長: A measure of ductility, indicating how much a material can stretch before breaking. Higher percentages indicate better formability and resistance to cracking.
- 硬度: Represents a material’s resistance to deformation and wear. Different hardness levels can influence the choice of stainless steel for specific applications.
- 熱伝導率: Indicates how well the material conducts heat. This property is important in applications where heat transfer is a factor.
