Choosing between 1. tool steel and 1. tool steels can greatly affect your project. They both work great.But they excel in different areas like heat resistance, wear, or machinability. Are you unsure which steel to use for your next heavy-duty job? One of these could be just what you need. However, there’s one important factor to consider that might change your decision.

Tool steels’ composition works like a secret formula. This formula decides how well they perform and what jobs they handle best. Take grades 1. and 1.. Their carbon, vanadium, and other element ratios create the right balance for specific tasks. I find it’s like selecting the proper tool. Each grade has unique strengths and features made for particular challenges.1. has much more vanadium (0.85-1.15%) than 1. (0.30-0.50%). Vanadium boosts strength at high temperatures. It also improves wear resistance and hot hardness.
When it comes to tough tasks, 1.’s extra vanadium is like a shield, giving it incredible wear resistance. I’d definitely recommend it for the heavy-duty work where things are bound to get rough. It can take the heat—literally—thanks to the added vanadium and carbon, standing strong even under extreme conditions. On the other hand, 1. has a bit less vanadium and carbon, which makes it tougher, like a reliable companion that bends without breaking. It’s perfect for jobs where you need that balance of flexibility and strength. So, if you’re facing high heat or wear-and-tear, go for 1.. But if toughness and flexibility are the stars of the show, 1. has got you covered.
Comparing 1. and 1. tool steels shows clear differences in four areas: Toughness.Heat resistance .Hardness.Wear resistance. They’re like two strong competitors. Both last long, but each has strengths that decide success based on the job. I think small property changes strongly affect results in sudden heat situations or extended use. From my experience, it’s like picking between two good options. One handles heat slightly better. The other holds up against friction and abrasion over time.
After heat treatment, both 1. and 1. tool steels become very hard. They reach 46 to 54 HRC. I’ve used both steels for tooling jobs, and they perform well in real-world situations.But let’s talk about heavy workloads. During high-speed cutting or molding tasks, I’ve noticed differences. 1. handles sudden impacts better because it bends more easily. 1. works differently—it keeps tools sharp longer and stays strong even when heated. This makes it better for jobs involving friction or heat.Need impact resistance? Pick 1.. Want something that lasts longer under friction? Choose 1.. Both steels deliver reliable results depending on your needs.
The toughness of 1. is better, which is suitable to withstand the alternating cold and hot conditions. 1. pays more attention to the balance of strength and hardness.
Tool Steel Grade Elongation Impact Toughness/Tensile Strength Features 1. about 10 – 15% 14 – 18 J/cm² Has good plasticity and resistance to cold and heat fatigue 1. Slightly lower (about 20%) – MPa Toughness is slightly less than 1., but adjustable by tempering1. tool steel has a wide range of heat-resistant temperatures. It is recommended to use a hardness of 40-50 HRC to maintain high temperature stability 1. heat cracking performance is outstanding. High temperature strength is higher. Suitable for long-term work in 500-600℃ environment (such as aluminum die casting mold). Both are suitable for high temperature scenarios, but 1. has better thermal cracking resistance and oxidation resistance at extreme high temperatures.
In tough environments like die-casting, 1. lasts longer than other materials. It can handle extreme heat and wear better than most. I saw this myself in a steel forging plant last year. The 1. dies performed well under high temperatures, while others started to wear down. It keeps going even when conditions are tough. This durability in heat and friction is why it’s trusted for heavy-duty tasks, making it perfect for jobs that require both strength and precision.
For shaping and cutting tool steels, 1. machines better than 1.. I’ve worked with both grades and prefer 1.’s lower alloy content – it processes smoother for detailed tool shapes. Last month, we made a die-casting mold using 1.. The material’s predictable behavior helped us finish faster and under budget while keeping quality high. This matters most for budget-driven jobs where speed and efficiency decide success.
1. is more cost-effective than 1., mainly due to its lower alloy content. From my experience, this makes it an excellent option for projects that demand budget-conscious decisions. I’ve worked on several manufacturing jobs where cost was a major factor, and in those cases, 1. came through perfectly. Its reduced alloy mix doesn’t sacrifice essential performance, making it a reliable steel choice when financial flexibility is limited. The practical advantages of 1. lie in its balance—offering great toughness at a lower price point without compromising key features.
1. and 1. tool steels are dependable in tough conditions. They excel in high-pressure environments like die casting, forging, and plastic molding. These steels perform well under extreme heat, where precision and durability matter most. Both have their own advantages but are designed to succeed in the most demanding industrial tasks.
Steel Grade Applications 1. (H11) Die casting tools for aluminum, magnesium, and zinc alloys1. is selected for more demanding high-temperature applications due to its superior hot hardness and wear resistance.

1. is better suited for larger dies or tools with complex geometries, offering improved toughness.
1. is favored for high production volumes and longer run times, particularly in severe service conditions.
Both steels are commonly used in similar industries, but 1. is typically chosen for applications that require higher performance and tool longevity, often influenced by operational temperature, production scale, and cost factors.
Both grades are sold globally through major suppliers. From my experience, 1. is easier to get immediately, while 1. often needs advance planning for custom orders or rare sizes. I recommend ordering early if you need special treatments like heat processing or certifications – these add time to deliveries for both steels.
H13 steel (American standard AISI) and 1. steel (German standard DIN) are both widely used hot working die steels, but there are certain differences in composition, performance and application scenarios. Here is a comprehensive comparison of the two:
What are the main differences in the chemical composition of H13 and 1. steel?
Scenarios where H13 is preferred:
Scenarios where 1. is preferred:
Heat treatment specifications:
Surface treatment:
Welding repair:
H13 and 1. are both benchmarks for hot working die steel, but 1. significantly surpasses H13 in high temperature stability and thermal fatigue resistance through stricter molybdenum, vanadium ratio and carbon control, and is suitable for extreme working conditions; and H13 is still the first choice for aluminum alloy die casting and general hot working die with its mature supply chain and cost advantages. When selecting materials, it is necessary to comprehensively consider temperature, stress, life span and cost, and if necessary, performance matching can be verified through simulation tests.
