H13 vs H11 Tool Steel – Complete Comparison (Properties, Hardness, Applications, Price & Selection Guide)

H13 vs H11 Tool Steel, Which One Should You Choose?
Walk into any tool room, forging shop, or die manufacturing unit in India, and you’ll hear the same debate.
“Should this die be made from H13 or H11?”
At first glance, both steels look nearly the same. They are both part of the Hot Work Tool Steel family, contain chromium and molybdenum, and are built to perform in extreme temperatures. However, choosing the wrong material can significantly decrease die life.
- Choose H13 where H11 should have been used, and the die may crack under repeated impact.
- Choose H11 where H13 belongs, and excessive wear can shorten production life.
This complete guide explains everything you need to know before selecting either grade.

What is H13 Tool Steel?
H13 Tool Steel (DIN 1.2344, SKD61) is one of the world’s most widely used chromium hot work tool steels.
Its high vanadium content forms extremely hard carbides that improve:
- Wear resistance
- Hot hardness
- Heat checking resistance
- Tool life
- Surface finish
This makes H13 the preferred steel for:
- Aluminium Die Casting Dies
- Zinc Die Casting
- Plastic Injection Moulds
- Extrusion Dies
- Hot Shear Blades
- Forging Punches
What is H11 Tool Steel?
H11 Tool Steel (DIN 1.2343, SKD6) is also a Hot Work Tool Steel, but with a lower vanadium content.
The lower carbide volume gives H11:
- Better toughness
- Better impact resistance
- Better crack resistance
- Easier machining
It is commonly selected for:
- Hammer Dies
- Forging Dies
- Fastener Tooling
- Hand Tool Dies
- Heavy Stamping
Comparison of Chemical Composition H13 vs H11 Tool Steel
| Element | H13 (DIN 1.2344) | H11 (DIN 1.2343) |
| Carbon | 0.32–0.45% | 0.33–0.43% |
| Chromium | 4.75–5.50% | 4.75–5.50% |
| Molybdenum | 1.10–1.75% | 1.10–1.60% |
| Vanadium | 0.80–1.20% | 0.30–0.50% |
| Silicon | 0.80–1.20% | 0.80–1.20% |
| Manganese | 0.20–0.50% | 0.20–0.50% |
Main Difference:
The H13 with higher vanadium content has much better wear resistance and longer tool life.
Mechanical Property Comparison
| Property | H13 | H11 |
| Wear Resistance | Excellent | Good |
| Toughness | Good | Excellent |
| Hot Hardness | Excellent | Good |
| Thermal Fatigue | Excellent | Very Good |
| Heat Checking Resistance | Excellent | Very Good |
| Impact Resistance | Good | Excellent |
| Machinability | Moderate | Better |
| Polishability | Excellent | Good |
Hardness Comparison
| Condition | H13 | H11 |
| Annealed | 180–220 HB | 180–220 HB |
| Working Hardness | 44–52 HRC | 42–50 HRC |
| Maximum Practical Hardness | 54 HRC | 52 HRC |
Heat Treatment Process
1. Preheating (650–750°C)
2. Austenitizing
o H13: 1010-1025 °C
3. Air, Oil, or Vacuum Quenching
4. Double or Triple Tempering (550-650 °C)
Vacuum heat treatment is recommended for precision dies to minimise distortion.
One of the most asked questions from buyers is:
“What’s the cheapest steel?
Generally,
Why?
- Higher Vanadium content
- Better wear resistance
- Longer production life
- Higher performance in die casting applications
Although the initial purchase price is higher, H13 often delivers a lower cost per component because of its longer service life.
Price depends on:
- ESR or Conventional Grade
- Forged or Rolled Material
- Imported or Domestic Mill
- Size
- Heat Treatment
- Quantity
No fixed market price exists, so always request a quotation based on current stock.
H13 vs H21
| Feature | H13 | H21 |
| Toughness | Better | Lower |
| Hot Hardness | Excellent | Outstanding |
| Wear Resistance | Excellent | Excellent |
| Typical Use | Die Casting | Hot Forging & Extreme Heat |
H13 vs DIN 1.2367
| Property | H13 | 1.2367 |
| Toughness | Excellent | Higher |
| Hot Strength | Excellent | Excellent |
| Large Forging Dies | Good | Better |
There is virtually no practical difference. SKD61 is the Japanese JIS designation equivalent to AISI H13 and DIN 1.2344. Selection should focus on material quality, cleanliness, ESR option, testing, and supplier reliability rather than the grade designation alone.
H13 vs DB6
| Feature | H13 | DB6 |
| Type | Hot Work | Hot Work |
| Toughness | Excellent | Very High |
| Nickel Content | No | Yes |
| Large Forging Dies | Good | Excellent |
