SMR4 Steel

SMR4 Steel

Steel name: SMR4
Diagram No.: 1616
Chemical composition in weight %: 0.35% C, 0.30% Si, 3.00% Cr, 1.80% Mo, 0.70% V, 2.20% W, 2.20% Co
Steel group: Hot work tool steels
Properties: For heat treatment practice, austenizing temperature must be adjusted in the 1040 to 1080 C range for carbide element-formers solutioning. Quenching in high pressure gas medium must be as drastic as possible. Two tempering cycles are recommended in the 560 to 680 C interval to adjust hardness inside the 42 to 52 HRC hardness range. Practically, the hardness levels under 45 HRC have in fact little application interest.
Applications: Forging tools, die casting moulds (copper, light alloys, etc.), extrusion dies, and moulds for glass industry.
Reference: Not shown in this demo version.
