MLQ Xtra Steel

Steel name: MLQ Xtra
Diagram No.: 2442
Mat.No. (Wr.Nr.) designation: 1.2738 mod.
AISI/SAE designation: P20 mod.
Chemical composition in weight %: 0.26% C, 0.35% Si, 1.00% Mn, 1.45% Cr, 0.55% Mo, 0.60% Ni, +others
Steel group: Plastic mould steels
Properties: MLQ Xtra is a new, patented, pre-hardened mold steel grade specially designed for through hardenability, ease of machining and simple postproduction mold maintenance. It has high impact strength and temper resistance and very high thermal conductivity that improves heat extraction and reduces molding cycle times. The well-balanced chemistry assures homogeneous hardness and microstructure in very large cross sections with nearly no section hardness loss due to mass. MLQ Xtra is an excellent material for Polishing, Photo-Etching & Acid Texturing. The highquality mold steel undergoes premium refinement through either Vacuum Arc Remelting or Electroslag Remelting, thus eliminating nearly all segregation and inclusions.
Applications: Moulds
Reference: Not shown in this demo version.
