Features:
1. ASSAB 8418 Mould Steel is the high level long life hot work, mould steel with Cr, Mo, V alloy, it applies the VAR-the state of art Vacuum consumable electro- arc remelting technology is widely applied in the world for superior purified steel production.
2. Has extremely high purity (low impurities and gas extra), structural refinement and high level toughness and ductility.
3. The Mo element ratio is much higher than the normal H13 steel, has more high-temperature strength (the anti shape change performance of the hot extrusion, hot forging and casting moulds is much better).
4. The anti-temper softening performance is much better, its performance in counter with softening, hot abrasion, shape change and heat-cracking is highly increased.
5. Heat treatment hardenability is better, and increased, the large size moulds total performance.
Application:
1.Suitable for long service life extrusion, casting, hot forging mould, for example, automobile and motorcycle engine shell body, car lamp radiation shell casting mould
2.Also suitable for sophisticated shape aluminum extrusion mould (eg. Sunflower, etc).
