DIN 1.2436 is German DIN standard extra high toughness chromium steel and cold work mould steel. Has extremely high wear resistance and edge retention capabilities. It is a widely used cold work die steel with high strength, good hardenability and good wear resistance, but the weak point is it poor impact toughness. 1.2436 adds 0.6%-0.8% tungsten compare with 1.2080, so its wear resistance is better than 1.2080 steel. However, compared with 1.2379, because a certain amount of vanadium is added to 1.2379 steel , it toughness performace better than 1.2436. Therefore, 1.2436 s mainly used for cold stamping dies and punches, cold cutting shears, drill bushings, and gauges that bear smaller impact loads and require high wear resistance , drawing dies, impression dies, thread rolling dies, drawing dies and thread rolling dies, etc.
Standard:
DIN 1.2436 belong to German Industrial Standard (DIN) DIN EN ISO 4957 .
