DC53 Chemical Composition

  • C: 1.00%, medium-high carbon content ensures sufficient hardness with better toughness and balanced performance than high carbon steel.
     
  • Si: 0.90%, high silicon improves strength and temper resistance, maintaining stable hardness after heat treatment.
     
  • Mn: 0.35%, proper manganese enhances hardenability and avoids brittleness.
     
  • P, S ≤ 0.030%, strictly controlled impurities ensure high purity, improving toughness and service life.
 

M390 Chemical Composition

  • C: 1.90%, nearly twice that of DC53, forms hard carbides with vanadium for superior wear resistance.
     
  • Cr: 20.00%, ultra-high chromium provides excellent stainless steel level corrosion resistance.
     
  • V: 4.00%, high vanadium forms fine and uniform VC carbides via powder metallurgy technology.
     
  • P, S ≤ 0.030%, strict impurity control and powder metallurgy process achieve extremely high material purity.

In the comparison between DC53 Steel vs M390, DC53 is a versatile all-round steel, while M390 excels in high wear resistance and rust proof. Choose based on your usage.

Hardness and Mechanical Properties of DC53 Steel vs M390

DC53 Properties

  • Quenched Hardness: 60–62 HRC
     
  • Bending Strength: approx. 2700 MPa
     
  • Impact Toughness: approx. 30 J/cm², twice that of D2 steel
     
  • Compressive Strength: approx. 2200 MPa
 

M390 Properties

  • Quenched Hardness: 60–62 HRC
     
  • Bending Strength: approx. 2000 MPa
     
  • Impact Toughness: 15–20 J/cm²
     
  • Wear Resistance Index: 30–40% higher than DC53

Both have equal hardness. DC53 tool steel owns 1.5 to 2 times higher toughness than M390, while M390 takes the lead in wear resistance and corrosion resistance. In the comparison of DC53 Steel vs M390, neither is absolutely superior, only more suitable for specific applications.

Corrosion Resistance of DC53 Steel vs M390

DC53 Corrosion Resistance

Chromium content around 8%, classified as tool steel without stainless steel level corrosion resistance. Surface treatment is required in humid environments to avoid rusting.

M390 Corrosion Resistance

High chromium content up to 20%, combined with Mo and V, offers corrosion resistance close to 316L stainless steel, no extra surface protection needed.

If your products contact water, blood, food or chemicals, or work in humid environments, you have to choose M390.

Wear Resistance of DC53 Steel vs M390

  • DC53: Contains Cr and Mo carbides with high hardness and fine distribution, featuring great wear resistance.
     
  • 1095: Only has iron carbide, lower hardness and average wear resistance.

DC53 boasts 30%-50% higher wear resistance than 1095. After 100,000 stamping cycles, DC53 wears about 0.01mm, while 1095 wears 0.02-0.03mm.

Corrosion Resistance of DC53 Steel vs M390

  • DC53 Corrosion Resistance:8-9% Cr, decent rust resistance. Pitting occurs after 12-24 hours salt spray test.
  • 1095 Corrosion Resistance: Nearly 0% Cr, highly prone to rust. Red rust appears within 2-4 hours salt spray test.
DC53 has far better corrosion resistance than 1095. Choose DC53 if tools or dies expose to moist air or hand sweat. Strict rust prevention is a must for 1095.

Machinability of DC53 Steel vs M390

  • DC53 Steel Machinability: Annealed hardness ≤223 HB, low vanadium content for good grindability and slight wire cutting deformation.
  • M390 Steel Machinability: Annealed hardness around 280 HB, rich vanadium carbides lead to poor grindability and easy cracking during wire cutting.
In terms of machinability, DC53 is far better than M390. M390 requires special grinders and grinding wheels, with processing cost 30%-50% higher.

Heat Treatment of DC53 vs 1095

DC53 Heat Treatment Parameters

  • Annealing temperature: 850–880°C
  • Quenching temperature: 1020–1050°C
  • Tempering temperature: 180–220°C (double tempering recommended)
  • Quenching medium: oil quenching or vacuum quenching
  • Heat treatment deformation rate: extremely low, within 0.05%

1095 Heat Treatment Parameters

  • Annealing temperature: 790–820°C
     

    Quenching temperature: 790–830°C

  • Tempering temperature: 150–200°C
  • Quenching medium: water quenching or oil quenching
  • Heat treatment deformation rate: relatively high, 0.1%–0.2%
In short, DC53 has little heat treatment deformation and stable size, perfect for precision parts within ±0.01mm tolerance. 1095 is cheaper with lower quenching temperature, but deforms more and needs extra finishing, increasing total cost.

Cost Reference of DC53 vs 1095

  • DC53: Cost index 100 (benchmark)
  • M390: Cost index 130–150 (about 30-50% more expensive)
Reason: M390 is produced by powder metallurgy with complex procedures and high raw material cost, featuring much better performance stability and uniformity.

Typical Application Scenarios of DC53 vs 1095

Choose DC53

  • Precision cold stamping dies, blanking dies
     
  • Molds requiring high toughness and high hardness
     
  • Thin edges and sharp corners free from chipping
     

    Cost-sensitive projects needing balanced overall performance

     
  • Replace D2 steel for better toughness

Choose M390

  • High-end knives: kitchen knives, hunting knives, tactical knives
     
  • Medical surgical instruments
     
  • Food processing equipment parts
     
  • Precision measuring tools
     
  • Parts needing mirror polishing and corrosion resistance

Heat Treatment of DC53 vs 1095

DC53 Heat Treatment Procedure

  1. Annealing: 800–850°C, furnace cooling
     
  2. Preheating: Two-stage preheating at 650°C and 850°C
     
  3. Quenching: 1020–1040°C, oil cooling or gas cooling
     
  4. Tempering: 150–200°C (twice), final hardness 60–62 HRC

M390 Heat Treatment Procedure

  1. Annealing: 850°C, furnace cooling
     
  2. Preheating: Two-stage preheating at 600°C and 850°C
     
  3. Quenching: 1050–1080°C, gas cooling (vacuum furnace recommended)
     
  4. Tempering: 180–200°C (twice), final hardness 60–62 HRC

M390 needs higher precision in temperature control during heat treatment. Vacuum furnace is suggested with temperature error within ±5°C, or final hardness and toughness will be affected.

Conclusion

DC53 features excellent toughness, easy processing and high cost performance, ideal for various cold working dies. M390 boasts superior wear and corrosion resistance, perfect for cutlery, medical devices and food-grade parts. Choose properly based on actual needs.
