1) Features of high wear resistance XW42 cold work tool steel
YSP XW-42 is a high chromium steel with molybdenum and vanadium hardness heat treatment xw42, good wear resistance, good compression resistance, general hardening, good resistance to temper softening.
2) Using high wear resistance XW42 cold work tool steel
The XW-42 is suitable for molds requiring good wear resistance and adequate toughness (impact resistance), as well as for cutting thick, loaded molds for forming and processing.

1) XW42 soft annealing: heated to 850 degree under protection, kept for 2 hours, then cooled to 650 degree in the oven at 10 degree/hour, air cooled.
2) XW42 stress-relieved: temperature of 650 degree, cooling in oven at 500 degree for 2 hours, air-cooled. XW42 must be stress relieved from the mold steel after rough machining
(3) XW42 cooling: preheating temperature 600 ~ 700 degree ; the austenitizing temperature of 900 ~ 1050 degree ; The usual temperature of 1000 ~ 1040 degree. XW42 mold steel must be protected when heated to the cooling temperature xw42 what material is mold steel in order to decarburization and oxidation. Isothermal quenching temperature of 180 ~ 500 degree, then air quenching, quenching to 50 ~ 70 degree immediately quenching.
4) Deep quenching and aging treatment: When the mold needs maximum dimensional stability, deep quenching treatment or aging treatment should be carried out.
Quenching immediately after cold treatment xw42 heat treatment hardness of about 70 ~ 80 degree, holding 3 ~ 4 then volatile or timely xw42 what material is mold steel? XW42 deep cold treatment, mold steel can increase the hardness of 1 ~ 3 HRC. It should be noted that the complex shape of deep cold treatment may produce cracks. Spot treatment: quenching and tempering followed by aging at 110~140 degree for 25~100 hours.
Quenching and tempering
Nitriding XW42 die steel can be hardened diffusion layer, very wear resistant corrosion resistant xw42 what material is die steel? 525 degree oxygen nitriding, XW42 die steel surface hardness can reach 1250HV.
