As stated in the title, the topic we want to discuss is the difference between A2 and SKD11 performance, both of which are cold work die steels. A2 die steel is Fincola die steel, SKD11 die steel is produced from Hitachi die steel in Japan. What is the connection between the two and what is the difference.
First of all, let's talk about the cutting performance, after comprehensive comparison, A2 die steel machinability, abrasiveness are better than SKD11 die steel, which also prompted the use of A2 die steel processing to save hours, reduce the degree of tool damage, greatly reduce the processing cost.
In terms of heat treatment, A2 die steel also has an obvious point, which can reach the hardness that SKD11 die steel can not reach under ordinary quenching treatment. Therefore, this is to improve the hardness of the vacuum heat treatment defect.
A2 die steel also shows considerable confidence in the surface hardening, and its surface hardening hardness can be higher than SKD11 die steel, which broadens the use surface.
A set of mold wire cutting is often an indispensable link, SKD11 die steel sometimes occurs residual stress is not eliminated clean, leading to the problem of cracking and deformation during line cutting, which will not appear on the A2 die steel sold by Longtuo Metal.
Advantages in repair welding operation A2 die steel repair welding operation is easier because the preheating and after-heating temperature are lower than SKD11 die steel.
