T8, T10, and T12 Properties

T8 Steel

T8 steel gives you a balance between hardness and toughness. You find T8 in dies that need to keep their shape but do not face heavy impact. The chemical composition includes about 0.75-0.85% carbon, 0.17-0.37% silicon, and 0.17-0.37% manganese. After heat treatment, T8 steel reaches a hardness of 58-63 HRC. You use T8 for light to medium-duty bending operations. These dies work well for simple shapes and thin sheets.

T10 Steel

T10 steel stands out for its higher carbon content. You get about 0.95-1.04% carbon, 0.17-0.37% silicon, and 0.17-0.37% manganese. After heat treatment, T10 dies reach a hardness of 60-65 HRC. You choose T10 when you need more wear resistance and sharper edges. These dies work best for precision jobs and thin sheet metal. T10 is popular because it balances toughness and wear resistance. You can use T10 dies for repeated bending without losing accuracy.

• T10 is commonly used for bending machine tooling.
• T10 offers moderate toughness and high wear resistance.
• After heat treatment, T10 can achieve a hardness exceeding 60 HRC.
• T10 dies are cost-effective for many shops.

T12 Steel

T12 steel has the highest carbon content among these grades. You get about 1.15-1.24% carbon, 0.17-0.37% silicon, and 0.17-0.37% manganese. After heat treatment, T12 dies reach a hardness of 62-66 HRC. You use T12 when you need maximum hardness and wear resistance. These dies work best for fine blanking and forming thin materials. T12 dies do not handle heavy impact loads well, but they last a long time in low-impact jobs.

These elements improve toughness and wear resistance. Cr12Mo1V1 takes it further with even more molybdenum and vanadium. This grade gives you the best wear resistance and toughness for press brake dies.

Here is a chart that compares the hardness of these grades:

You also see D2 and 1.2379 used in press brake dies. These grades have a similar mix of carbon, chromium, molybdenum, and vanadium. The table below shows their composition:

You get more wear resistance as you add more chromium, molybdenum, and vanadium. These elements help your press brake dies last longer and resist cracking.

Here is a chart that shows the content of these elements:

• Cr12 gives you poor toughness and high brittleness. Carbides do not spread evenly, so you may see cracks.
• Cr12MoV improves toughness and wear resistance. You see fewer cracks and less deformation.
• Cr12Mo1V1 offers the best toughness, wear resistance, and oxidation resistance.

Wear Resistance and Hardness

You want your press brake dies to last as long as possible. High-carbon high-chromium steels help you reach this goal. These steels give you top-level wear resistance. You can use them for jobs where your dies face lots of friction and pressure.

The wear resistance of press brake die depends on the steel’s hardness and the way carbides form inside the metal. Cr12, Cr12MoV, and D2 all form hard carbides. These carbides protect your press brake dies from wearing out. You get less downtime and fewer replacements.

You will notice that Cr12MoV and D2 offer better wear resistance than plain Cr12. The added molybdenum and vanadium help the steel resist cracking and chipping. You can use these grades for high-volume jobs or when you bend abrasive materials.

Tip: If you want the best wear resistance, choose Cr12Mo1V1 or D2 for your press brake dies. These grades keep their edge and shape even after thousands of bends.

You also get high hardness with these steels. Most grades reach 57-65 HRC after heat treatment. This high hardness means your press brake dies cut and form metal with sharp, clean lines. You get precise bends and less tool wear.

High-Speed Steel and Carbide Tooling

When you use press brake tools, you want strong materials. High-speed steel and cemented carbide are both great for hard jobs. These materials help your tools last longer and work better. Each one has special benefits that can help you in your shop.

Selecting Press Brake Tooling Steel Grades

Key Selection Factors

There are many things to think about when picking press brake tooling. The right steel grade helps you do a better job and saves money. First, think about what kind of metal you want to bend. Mild steel is easy to bend and works with most dies. If you use high-strength alloy or stainless steel, you need stronger tooling that can handle more force and last longer.

The thickness of the metal is very important. Thin sheets need tooling with sharp edges and high hardness. Thick plates need dies that are tough and do not bend easily. How many parts you make also matters. If you make lots of parts, pick tooling that lasts a long time and keeps its shape. You want your dies to stay the same size and shape after many bends.

You should also check your press brake machine. Manual machines work best with lighter metals. Hydraulic and CNC machines can bend thicker plates and make more shapes. Make sure your tooling matches what your machine can do.

Here are some simple tips to help you choose:

• Check what kind of metal and how thick it is before picking a steel grade.
• Think about how many bends you will make each day.
• Make sure your tooling fits your press brake’s power and design.
• Look for steel grades that keep their shape and are tough.
• Think about how much the tooling costs and how long it will last.
