The heat treatment hardness of DC53 mold steel is higher than that of SKD11, Q355NH cold rolled railway steel strip, the high temperature is 520-530 ℃, and the high hardness can reach 62-63HRC after tempering. In terms of strength and wear resistance, mold steel DC53 exceeds SKD11 mold steel. The toughness is twice that of SKD11 die steel. The toughness of DC53 is more prominent in cold work die steel. Tools made with DC53 rarely crack and crack, greatly increasing the service life.

Q355NH cold rolled railway steel strip, S355J0 steel density is 7.85g/cm³. S355J0 density represents the mass per unit volume of S355J0 steel, which indirectly affects the price of S355J0 steel. Therefore, the density of S355J0 is also an important consideration for material selection. S355J0 steel tensile strength (σb / MPa):3

Titanium microalloying is an element of Q355NH cold rolled railway steel strip strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in Q355NH cold rolled railway steel strip tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.
