Thyssenkrupp 2311 Mould Steel
Characteristic 2311
2311 steel is a German Die steel, the steel by “super clean” production process, pre hardened, showing the height of micro pure and excellent homogeneous structure, excellent polishing and light etching engraving. After heat treatment, processing and polishing performance is good, can be carried out, and can be processed, suitable for the surface treatment of chrome, good toughness, good mechanical processing performance. Gold microstructure is martensite and bainite structure.
2311 steel offer in the condition of quenching and tempering Hardness is in the range of 280-325 HB (29-34 HRC), this result in high strength Worry free for size distorted after quenching Suitable for plastic mold with thickness less than 400 mm Very good for polishing and suit for plastic mold that need bright surface or need texturing
Outstanding Properties 2311
• Texturing ability due to low sulfer
• High Strength
• Can do EDM and Wire cut
• Homogeniety hardness throughout every area
• Risk free from bend as cause by heat treatment process
• Can do Nitriding , surface hardness at 650 HV
• Can do hard chrome , surface hardness at 1000 HV
