I just got off the plane today and received a consultation from Mr. Zhao about the fracture of the punch made of hard alloy during cold extrusion of No. 20 steel. May I ask if there is any tool\u00a0steel<\/a><\/strong>\u00a0with higher hardness and better toughness than tungsten steel.<\/p>\n\n\n\n

Mr. Zhao was introduced by his old customer Mr. Qiu. Mr. Zhao said that when we went back to the village for the holiday, we happened to have a conversation with Mr. Qiu about the mold. Mr. Qiu recommended me to come find you.<\/p>\n\n\n\n

I am quite happy to hear this news. During the holiday, we can talk about molds and also talk about Yuhui Tool<\/strong> Steel<\/strong>. They also recommended new customers to me. Thank you, Mr. Qiu.<\/p>\n\n\n\n

But on the other hand, cold extrusion of No. 10 steel has sharp corners, and the punch must have high strength, high wear resistance, and high toughness without collapsing corners. It is still a low carbon steel of No. 10 steel, and the problem of sticking and drawing must be considered. Based on past case experience, I recommend our Yuhui PM23 powder high-speed steel for this working condition.<\/p>\n\n\n\n

 Yuhui PM23 is a powder high-speed steel produced using advanced powder metallurgy technology, which eliminates carbide segregation defects, removes microscopic cracks that are invisible to the naked eye on the structure, and does not stick to the mold or cause wire drawing, resulting in a smooth surface of the extruded product; It also improves the anti cracking performance of the mold steel, and the hardness of PM23 is 64-66HRC. It can be said that PM23 has both high hardness and high strength, and making this type of gear cold extrusion punch will not cause corner collapse or cracking.<\/p>\n\n\n\n

Mr. He’s gear cold extrusion mold in Chongqing uses PM23 powder high-speed steel, which has a better effect than hard alloy and a lifespan of more than 30000 times, with good smoothness.<\/p>\n\n\n\n
