Whether you’re looking to use this material for 3D printing or tooling, this guide will provide the insights you need to make informed decisions.
Overview: What is Wear Resistant Steel 1.2343 Spherical Powder?
1.2343 steel (also known as X37CrMoV5-1 or H11 in some standards) is a hot-work tool steel that’s been specifically designed to offer high wear resistance and toughness at elevated temperatures. This makes it a go-to material for applications like die casting, forging tools, and extrusion dies.
When produced as a spherical powder, 1.2343 steel is ideal for additive manufacturing processes such as Selective Laser Melting (SLM) and Electron Beam Melting (EBM). The spherical shape of the powder particles ensures better flowability, making it easier to spread thin layers during 3D printing. Additionally, the material’s high hardness and heat resistance make it perfect for producing durable parts that can withstand extreme wear conditions.
