1.2311 and 1.2378, which is one is more suitable for you?

Nowadays, with the development of economic, plastic plays an important role in our daily life. so the plastic mold steel also important for us. Plastic mold steel is mold steel for plastics. Plastic mold materials are mainly based on mold steel. 1.2311 and 1.2378 steel is the typical mold steel.

 

Both of them are produced by the German DIN standard. The development of mold steel has promoted the development of industrial products in the direction of advanced, diversified, personalized, and high added value.

 

what’s the difference between 1.2311 and 1.2738?

1.2311 tool steel is a mold material for plastic injection, it belongs to the high-quality medium carbon, Pre-hardness(28~34HRc), Cold work plastic mold steel. It is no need for further heat treatment. so you don’t have any worry about distortion or cracking. 1.2311 steel is most widely used to plastic mold material in injection plastic mold.

 

After heat treatment, processing and polishing performance is good, 1.2311 can be carried out, and can be processed, suitable for the surface treatment of chrome, material hardness even (to 400mm thick), good toughness, good mechanical processing performance. Main be applied to in zinc, aluminum, magnesium, and its alloy die-casting mold; Hot-pressing mold, all kinds of a hot forging die; Metal extrusion dies, die set.

 

1.2738 steel has relatively superior mechanical properties and good processability among similar grades of steel. Since the1. 2738 mold steel has been pre-hardened, when it leaves the factory, it can be directly used for processing, thereby reducing the heat treatment, link in the normal mold production, it processing and improving economic benefits. It’s pre-hardened plastic mold steel, executes standard 29-33HRC.

 

1.2738 with about 1% nickel content. Due to the addition of the nickel element, its harden ability is improved, and the hardness distribution of large sections, and thick plates is uniform.

 

1.2738 is mainly used in large plastic molds and mold bases, such as automobile bumpers and TV shell molds. Suitable for molds requiring high lightness, such as the production of hard rubber (PS),and ultra-hardened rubber (ABS), etc. televisions, fax machines, plastic parts for home appliances, and automotive parts that require a certain degree of polishing. its characteristics are: excellent processing performance, easy cutting and polishing and electrical corrosion performance.
