DIN 1.2312 steel is a high quality plastic mold steel material.it is usually delivered in pre-hardness condition and hardness 28~34HRC.

Chemical composition: 1.2312 is mainly composed of carbon (C), chromium (Cr), manganese (Mn), sulfur (S) and other elements. Among them, the chromium content is about 1.8%, which can improve its corrosion resistance and hardness. The content of manganese is about 1%, which can improve its toughness and wear resistance. The sulfur content is about 0.06%, which can improve its processing performance.

Mechanical properties: it has good mechanical properties, and its hardness and strength are relatively high. At the same time, 1.2312 also has good toughness and wear resistance, and can maintain stable performance in high-load environments. In addition, the corrosion resistance of 1.2312 is also very good, which can avoid rust and corrosion on the tool surface.

Processing properties: 1.2312 has good processability and plasticity, and is easy to process and plastically deform. Conventional processing equipment and techniques, such as drilling, turning, milling, etc., can be used to obtain the required shape and performance.

Application: it is widely used in manufacturing molds, plastic molds, die-casting molds and other tools and parts. In the field of molds, 1.2312 can be used to manufacture high-load tools such as injection molds, extrusion molds, and blow molds. In the field of plastic molds, 1.2312 can be used to manufacture plastic molds, thermoplastic molds, etc. In addition, 1.2312 can also be used to manufacture high-strength and high-wear-resistant parts such as die-casting molds and stamping molds.

In short, 1.2312 has good mechanical properties, wear resistance, corrosion resistance and processing properties. It is a commonly used mold steel and is widely used in the field of tool and parts manufacturing.
