Thank you for your question, KJYM!
The physical properties of SK5M are as follows.
-Young’s modulus: 206000N/mm^2
-Poisson’s ratio: 0.3
-Specific gravity: 7.85
-Elastic limit stress: Allowable bending stress is 75% of the tensile strength of the material.
By the way, in the case of SK5M, it varies from 1100 to 1150 N/mm, although it may vary depending on the plate thickness.
We are happy to answer any inquiries regarding technology, specifications, materials, etc. Please feel free to ask.
