Thyssenkrupp Mould Steel

Characteristic

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.

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

&#;  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 HV

HEAT TREATMENT DATA

Forging of

Slowly Heat to 930- °C, keep the temperature to heat thoroughly. Start forging. Finished cool slowly.

Annealing of

Heat to 775 to 790 °C, soak enough time, ensure heat thoroughly. then cool in the  heat treatment furnace.

Quenching of material

820-840°C, quench in oil.

Tempering of

Heat uniformly at the tempering temperature for steel material. keep enough time, then cool in air

Advice temperature 100 to 600 °C. more steel heat treatment data, pls contact your heat treatment supplier,.

Processing

steel round bar and flat sections can be cut to your required sizes. mould steel ground bar can also be supplied, providing a high quality tool steel precision ground tool steel bar to your required tolerances. mould steel is also available as Ground Flat Stock / Gauge Plate, in standard and nonstandard sizes.

Application

Alloy die-casting mould ; Hot-pressing mold, all kinds of hot forging die; Metal extrusion die, die set.

DIN 1. PLASTIC MOULD STEEL

DIN 1. Plastic Mould Steel CHEMICAL COMPOSITION (Typical Analysis in %)

DIN 1. steel is the pre hardened plastic mould steel and the hardness is distributed uniformly in large cross sections that have fantastic weldability with minimum hardness, high polish ability and less streak texture making finishing easier.

STEEL PROPERTIES

• DIN 1. steel is pre-hardened plastic mould steel
• Hardness is distributed uniformly in large cross sections
• Fantastic weldability
• Size Section accessibility up to 255 mm thickness
• Supply hardness is 240-280 BHN
• Least hardness elevation
• Good mirror polish ability
• Less streak texture making finishing easier

APPLICATION
The DIN steel is an equivalent to P20 plastic mould steel and used for die holders, casting dies, zinc die, bolsters, backers, shoe blocks, injection moulds, mould frames for plastic moulds, pressure casting moulds, recipient sleeves etc.
