P20 Steel Equivalent Grade Chemical Composition

Main characteristics of P20/1.2311 steel

Vacuum degassed and refined, P20 steel has high purity and is suitable for plastic molds that require polishing or etching.
P20 steel is supplied in pre-hardened (quenched and tempered) condition and can be used directly for mold processing without heat treatment, shortening the construction cycle.
After forging and rolling, P20 steel has a stable and uniform structure with 100% ultrasonic inspection and no porosity or pinhole defects.
P20 has good machinability and mirror polishability.

Applications of P20 /1.2311 Steel
AISI P20 tool steel is used for low temperature applications, including injection and die casting molds. Typical applications are.

- For large injection moulds and compression moulds
- Extrusion dies for thermoplastics
- Blow molding molds
- High strength brackets, plates and bolts
- Forming tools, stamping brake dies (possibly flame hardened or nitrided)
- Aluminum die-casting prototype molds
- Zinc die casting dies
- Long-run die casting dies
- Structural components, shafts

P20/DIN 1.2311 Steel Buying Guide
As the representative steel in plastic mold steel, P20 and 1.2311 steel have a wide range of industrial applications, and this huge demand has also led to the uneven quality level of these two materials in the market. How to choose high quality P20 and 1.2311 steel is a challenge for consumers.

Therefore, we will do something right and meaningful to help you choose P20 and 1.2311 steel wisely and effectively with this guide and stop worrying about not being able to start.

If you have such a need, then start learning from here.

How to make high quality P20/DIN 1.2311 steel?
In recent years, with the development of plastic industry, plastic products tend to be larger and more complex, which puts forward higher requirements on the performance of plastic mold steel, especially P20/DIN 1.2311, which is the main grade of plastic mold steel.

We need to face the challenge of making high quality P20/DIN 1.2311 steel, which is a very objective challenge. Here are a few key factors we can start from.

Chemical composition control
In addition to certain strength and toughness, plastic mold steels require machinability, hardenability, wear resistance, corrosion resistance and mirror finish properties.

Considering the above, the chemical composition control of P20 steel should first meet the standard requirements, and then further balance and optimize the production cost economy and process performance of P20 steel.

Metallurgical Quality Control
In order to manufacture high quality P20 steel, the metallurgical quality of P20 steel must also meet the following requirements.

Where can I buy high quality P20/DIN1.2311 steel?
We often hear customers complain that the composition and hardness of the P20 steel they buy do not meet the requirements, and what is even more annoying is that the material is not ideal for use when it is finally made into a finished mold, resulting in a lot of wasted labor, material and time costs.

We empathize with our customers' feedback and hereby guarantee that the P20 steel we produce can fully satisfy our customers' needs because we have rich production experience, a complete set of quality reports and after-sales support services. We believe that our professionalism can completely solve the problem for our customers.
