Length : 300mm

Hardness : HRC 66-68

Material : High Speed Steel

●Product Features :

High temperature calcination, quenching processing technology, high temperature resistance.

High hardness, wear-resistant and durable, processed by multiple heat treatment processes. (HRC66-68)

The sharp steel is rusty after a long time, grind it and put on some anti-rust oil, it is not easy to rust.

●Use of products :

Due to the high hardness of high-speed steel, so ordinary drills and so on is not drilled into,

it is recommended to use wire-cutting perforation (a specialized equipment to hit the eye,

does not affect the hardness of the material), laser and other equipment to hit the eye, if you really

can not find these devices, the easiest way to use electric welding burn through (burned near the annealing will be).
