6CrW2Si

Description

6CrW2Si是在铬硅钢的基础上加入了一定量的钨而形成的钢种,因为钨有助于在淬火时保存比较细的晶粒,而使回火状态下获得较高的韧性。

6CrW2Si is a steel grade formed by adding a certain amount of tungsten on the basis of chromium silicon steel, because tungsten helps to preserve finer grains during quenching, and can obtain higher toughness in the tempered state.

Features

6CrW2Si钢具有比4CrW2Si钢和5CrW2Si钢更高的淬火硬度和一定的高温强度。 通常用于制造承受冲击载荷而又要求耐磨性高的工具.

6CrW2Si steel has higher quenching hardness and certain high temperature strength than 4crw2si steel and 5CrW2Si steel. It is usually used to manufacture tools that bear impact load and require high wear resistance

6CrW2Si Steel Application

①适用于用碳工钢制造而承载能力不足,易于脆裂,而用高速钢或高强度钢制造,又不经济的高耐磨的模具。

②当模具以磨损和堆塌为主要失效形式时,可改用此钢。

③适用于制造剪刀、切片冲头等。

④可用于重负荷下工作的冲模、压模、铸造精整工具、风动凿子等。

⑤作为热加工用钢,可生产螺钉和热铆的冲头。

⑥高温压铸轻合金的顶头。

① It is suitable for high wear-resistant molds made of carbon steel with insufficient bearing capacity and easy embrittlement, and made of high-speed steel or high-strength steel.

② This steel can be used when wear and collapse are the main failure forms of the die.

③ Suitable for manufacturing scissors, slicing punches, etc.

④ It can be used for stamping dies, dies, casting finishing tools, pneumatic chisels, etc. working under heavy load.

⑤ As hot working steel, it can produce screws and hot riveting punches.

⑥ Plug of high temperature die casting light alloy.

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.
