Hey there! As a brake die steel supplier, I often get asked about the common grades of brake die steel. So, I thought I'd share some insights on this topic. Brake die steel is super important in the manufacturing of brake components. It needs to have the right properties to withstand high pressure, heat, and wear. Let's dive into the common grades.
D2 Steel
D2 steel is one of the most well - known grades in the brake die steel world. It's a high - carbon, high - chromium cold - work tool steel. This steel has excellent wear resistance, which is crucial for brake dies as they are constantly in contact with other materials during the manufacturing process.
The high chromium content in D2 steel forms chromium carbides, which are very hard and help in reducing wear. It also has good dimensional stability during heat treatment. This means that when we heat - treat the D2 steel to get the desired hardness and other properties, it doesn't change its shape too much.
However, D2 steel has some drawbacks. It's relatively difficult to machine compared to some other grades. Also, it's prone to cracking if not heat - treated properly. But overall, it's a great choice for brake dies that require high wear resistance, like those used in stamping brake pads.

H13 Steel
H13 steel is a hot - work tool steel that is widely used in the brake die industry. It can handle high temperatures very well, which is a big plus for brake dies as they can get really hot during the forging or casting processes of brake components.
This steel has good toughness, which means it can withstand impact loads without breaking easily. It also has excellent thermal fatigue resistance. Thermal fatigue occurs when a material is repeatedly heated and cooled, which is a common scenario in brake die manufacturing.
H13 steel is relatively easy to machine compared to D2 steel. It can be heat - treated to achieve different levels of hardness depending on the specific requirements of the brake die. For example, if a brake die needs to be more wear - resistant, we can heat - treat it to a higher hardness. But if it needs to be more tough, we can adjust the heat - treatment process accordingly.
S7 Steel
S7 steel is a shock - resistant tool steel. It's known for its high impact toughness, which makes it a great choice for brake dies that are subjected to sudden and heavy loads. In the brake manufacturing process, there can be situations where the die experiences a lot of force all at once, like during the forging of a large brake component.
S7 steel can handle these shock loads without cracking or deforming. It also has good ductility, which means it can be bent or stretched a bit without breaking. This property is useful during the forming process of the brake die itself.
However, S7 steel doesn't have the same level of wear resistance as D2 steel. So, it might not be the best choice for brake dies that are in constant contact with abrasive materials. But for applications where impact toughness is the primary concern, S7 steel is a top pick.
A2 Steel
A2 steel is a medium - alloy cold - work tool steel. It offers a good balance between wear resistance and toughness. It has less carbon and chromium compared to D2 steel, which makes it a bit easier to machine.
The wear resistance of A2 steel comes from the formation of fine carbides during the heat - treatment process. These carbides help in reducing the wear when the brake die is in contact with other materials. It also has good dimensional stability, similar to D2 steel.
A2 steel is often used in brake dies where a combination of wear resistance and the ability to be machined easily is required. For example, in the production of small - to - medium - sized brake components where precision machining is important.
Comparison of the Grades
When it comes to choosing the right grade of brake die steel, it really depends on the specific application. If wear resistance is the most important factor, D2 steel might be the way to go. But if high - temperature performance is crucial, H13 steel would be a better choice.
S7 steel is ideal for applications with high shock loads, while A2 steel is great for a balance of wear resistance and machinability. It's also important to consider the cost. D2 steel, for example, can be more expensive due to its high alloy content and the difficulty in machining it.
