In the mechanical blade industry, round blades are used for a wide range of purposes, and they are called differently in various industries. For example, round blades, round knives, round knives, round cutting blades, and slitting round knives all belong to the round blade category.

Below we count the materials of the round blades: materials are divided into: high-speed steel W18, 6542, SKD-11, Cr12MoV, H13K, common materials are divided into: 6CrW2Si, 9CrSi, 40Gr, 65MN and other materials.

The weight calculation method of the round blade: The calculated data of the outer circle x outer circle x thickness x 0.617 is the weight of the round blade, such as: outer diameter 100mmx100mmx5mmx0.617=30850 about 0.31Kg.
