Description

6CrW2Si steel is a kind of steel grade formed by adding tungsten elements based on chromium silicon steel. It preserves the finer grains during quenching after tungsten is added. And it obtains higher toughness in the tempered state. 6CrW2Si steel has higher quenching hardness and certain high-temperature strength of 4CrW2Si steel and 5CrW2Si steel.

Features

6CrW2Si steel has higher quenching hardness and high-temperature strength than 4CrW2Si steel and 5CrW2Si steel. It is usually used to manufacture tools that withstand impact loads and require high wear resistance.

Application

  1. Used to make scissors and slicing punches.
  2. Die, die, casting finishing tool, pneumatic chisel used for working under heavy load.
  3. As a hot processing steel. It can produce screws and hot riveting punches.
  4. High temperature die-cast light alloy head.
