Resolution of Tensile Testing Machine The resolution of tensile testing machine refers to the smallest change in Force or Displacement that the machine can detect. A high-resolution tensile testing machine can provide more precise testing data, which helps better analyze the mechanical behavior of ... Read More

What is the Hardening Case Depth? In powder‑coating and heat‑treatment processes, the case depth (often called the hardened layer thickness) is a critical parameter that determines wear resistance and fatigue life of a component. The depth is primarily governed by the diffusion of carbon (or other ... Read More
