SKD11
Tool Steel
Equivalent Grades: GB Cr12MoV, JIS SKD11, AISI/SAE D3, DIN 2X165CrMoV12. SKD11 is the tool steel, die steel, and high carbon steel possessing high hardness, strength and wear resistance. Its surface is grinded precisely. It is often used for the stamping dies, plastic molds, and so on.
High-Carbon High-Chromium alloy steel
Purpose
SKD11 is widely used in cold work die steel.

- Steel Application
Drive Shafts
To allow for variations in the alignment and distance between the driving and driven components, drive shafts frequently incorporate one or more universal joints, jaw couplings. Therefore, they must use the materials which are strong enough to bear the stress, whilst avoiding too much additional weight as that would in turn increase their inertia.The materials of drive shaft we recommend are as below.
