Baja Perkakas DC53 VS D2

We compare two common tool steels – DC53 and D2 – in simple terms to help you understand their differences and application scenarios and make your choice easier.

Perlakuan Panas-DC53 VS D2

First, let’s take a look at how DC53 and D2 are heat-treated:

• DC53: the quenching temperature is 940-960℃, the tempering temperature can be 180-220℃ or 520-530℃, and the hardness reaches 60-62HRC or 62-63HRC.

• D2: Quenching temperature is 980-1020℃, tempering temperature is 200℃, hardness is 60-62HRC.

Performance Comparison

Next, let’s look at the difference in performance between DC53 and D2:

• Ketangguhan: The impact toughness of DC53 is twice as much as that of D2. That is to say, DC53 is better able to carry the impact and is less likely to break.

• Wear resistance: DC53 is more wear-resistant than D2.

• Hardness after heat treatment: DC53’s hardness decreases less after tempering at high temperatures, while D2’s hardness will decrease more.

• Machining performance: DC53 has 30% less deformation than D2 in wire cutting, 15-20% higher grinding efficiency, and smoother surface finish.

Application Scenario

According to the above characteristics, we can give some suggestions for use:

• Scenarios requiring impact resistance: such as precision blanking dies or complex molding dies, it is more appropriate to choose DC53 because it is more resistant to impact.

• Need super wear-resistant scenarios, such as long-life punching dies or shear blades. D2 may be better because it also has good wear resistance and costs lower than DC53.

• Need to wire cutting processing scenarios: such as precision electronic molds, DC53 processing performance is good, with less deformation.
• Need to consider the cost-effective: such as ordinary stamping molds or standard parts production, the use of D2 is cost-effective.

Economic Benefit Consideration

According to our market experience, the unit price of DC53 is 18-25% higher than that of D2, but it can reduce 40% of mold maintenance, save 15-30% of processing time, and reduce 50% of product defective rate. So, all in all, the comprehensive cost of D2 is not necessarily lower than that of DC53. If the mold is complex and requires impact resistance or precision machining, the overall cost of DC53 may be lower. However, in the pursuit of wear resistance and simple working conditions, D2’s low price is obviously more advantageous.

DC53 is tough, wear-resistant, easy to process, and suitable for high-impact and precision machining occasions; D2 price, wear-resistant is also good, suitable for budgetary constraints or ultra-wear-resistant needs of the scene. Which steel to choose depends on your specific needs and budget. I hope this article can help you easily choose the right material!
