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.
Compared with H13 steel, RS407, RS418, SR19 can meet higher processing requirements, especially in terms of high temperature resistance, toughness...
