JIS G3459 SUS 317 TP Introduce
JIS G3459 SUS 317 TP steel pipes are most commonly used for applications that require a high level of durability and strength. Pipes produced utilizing JIS G3459 SUS 317 TP are ideal for a wide range of piping applications, including hot water transfer, steam systems, structural supports and boilers. The mechanical properties of a steel pipe are determined by the shape, strength, size and composition of the material. The mechanical properties of JIS G3459 SUS 317 TP steel pipes include tensile strength, yield strength, Young's modulus and hardness. Tensile strength, or the maximum stress a material can endure without being deformed or fractured, is typically measured in MPa. Yield strength is the stress that a material will experience when it reaches a specified yield point. Young's modulus measures a material's elasticity, or how much the material will stretch when a force is applied to it, and is expressed in GPa. Higher values indicate better elasticity. Hardness, or how resistant a material is to wear and abrasion, is measured in a variety of ways, including the Brinell scale.
