D2 Engineering Tips

Xử lý nhiệt

You need to pay close attention to heat treatment when working with D2 steel. This process helps you get the best hardness and toughness for your shear blade material. If you do it right, your blade will stay sharp and resist wear for a long time.

Here are some steps you should follow for D2 heat treatment:

1. Preheat the steel
   You should heat D2 slowly to about 1,400°F (760°C). This helps prevent cracks.
2. Austenitize
   Raise the temperature to 1,850°F (1,010°C). Hold it there for 30 minutes. This step makes the steel ready for hardening.
3. Quench
   Cool the blade quickly in air or oil. Air quenching works best for D2. This locks in the hardness.
4. Temper
   Heat the blade again to 400–600°F (204–316°C). Hold it for two hours. This step reduces brittleness and increases toughness.

Mẹo: Always check the hardness after tempering. You want your shear blade material to reach about 60–62 HRC for most cutting jobs.

You should use a controlled oven for each step. This helps you get consistent results. If you skip steps or rush, your blade may chip or break.

Edge Geometry

You must choose the right edge geometry for your D2 shear blade material. The shape of the edge affects how well your blade cuts and how long it lasts.

Consider these points when designing your blade edge:

• Edge angle
  A narrow angle (15–20°) gives you a sharper edge. This works well for cutting thin metal or plastic. A wider angle (20–25°) makes the edge stronger. You should use this for heavy-duty jobs.
• Edge thickness
  Thin edges cut cleaner but may chip faster. Thick edges resist damage but may not cut as smoothly.
• Bevel type
  Flat bevels are easy to sharpen. Hollow bevels stay sharp longer but are harder to maintain.

Ghi chú: You should match the edge geometry to your cutting task. If you cut hard materials, use a wider angle and thicker edge. For soft or thin materials, a narrow angle works best.

You can ask your blade supplier for help with edge design. Good edge geometry makes your shear blade material last longer and work better.

Engineering Advice

Xử lý nhiệt

Heat treatment changes how your shear blade material performs. You can make your blades harder or tougher by using the right heat treatment steps. If you want your blades to last longer, always follow the recommended process for your chosen steel or carbide.

• Preheat the blade before hardening. This step helps prevent cracks.
• Austenitize at the correct temperature. Each shear blade material has its own best range.
• Quench quickly to lock in hardness. Air or oil works best for most tool steels.
• Temper after quenching. This step reduces brittleness and adds toughness.

Mẹo: Use a controlled oven or furnace for even heating. Uneven heat can cause warping or weak spots.

Here is a quick guide for common materials:

The shape of your blade edge affects how well your shear blade material cuts and how long it lasts. You need to match the edge angle and thickness to your job.

• Narrow edge angles (15–20°) give you sharper cuts. Use these for thin or soft materials.
• Wider edge angles (20–25°) make the edge stronger. Choose these for hard or thick materials.
• Thicker blades resist bending and breaking. Use thick blades for heavy-duty work.
• Flat or slightly curved bevels help spread cutting force and prevent chipping.

Ghi chú: Always check your blade geometry before starting a new job. The right shape helps prevent breakage and keeps your cuts clean.
