The heat treatment hardness of DC53 mold steel is higher than that of SKD11, , 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,sa572 grade 60 low alloy steel sheet.
20 # material is a high-quality low-carbon carbon steel, cold-extruded, carburized and hardened steel. , 20 # material has low strength, good toughness, plasticity and good weldability. Chemical composition of 20 # round steel bar: C: 0.17 ~ 0.23, Si: 0.17 ~ 0.37, Mn: 0.35 ~ 0.65, S: ≤0.035, P: ≤0.035, Cr: ≤0.25, Ni: ≤0.30, Cu: ≤0.25. 20# carbon steel mechanical properties: Shear strength 275 ~ 392MPa, Tensile strength is 253 ~ 500MPa, elongation min. 25%.
The company strengthens process management and pays attention to assessment. One of the key points of good service is to strengthen the process management and improve the evaluation mechanism. Make the after-sales service system more perfect and provide better service for customers.
The company received new orders from Peru customer for more than 900 tons of ASTM A36 steel plates . These A36 steel plates will be used in the "Belt and Road" project - a mining conveyor project in Peru. This is our long-cooperated customer, who purchased thousand tons of A36 steel plates from us every year. And make our A36 steel plates well known in local.
