Property：
RS21 with high purity and excellent heat properties, toughness, wear resistance. The anti-temper softening performance is much better, its performance in counter with softening, hot abrasion, shape change and heat-cracking is highly increased. Heat treatment hardenability is better, and increased, the large size moulds total performance.
Application:
Suitable for long service life aluminum, copper die casting, piercer bar, hot forging mold for press. Also suitable for sophisticated shape aluminum extrusion mould
