DIN 1.2316 Steel is a type of stainless steel that belongs to the category of tool steels.
It is widely used in applications where resistance to corrosion, particularly in aggressive environments, is important, while also maintaining strength and hardness. Below is a detailed breakdown of DIN 1.2316 steel rounds:
Key Properties of DIN 1.2316 Steel:
- Composition:
- DIN 1.2316 is a high-quality stainless steel that belongs to the AISI 420 family of stainless steels.
- Its chemical composition typically includes:
- Carbon (C): 0.35-0.45%
- Chromium (Cr): 12.0-14.0%
- Nickel (Ni): 0.4-1.0%
- Molybdenum (Mo): 1.0-2.0%
- Manganese (Mn): 0.3-1.0%
- Silicon (Si): 0.3-1.0%
- Phosphorus (P) and Sulfur (S) are kept to very low levels.
- Corrosion Resistance:
- DIN 1.2316 is a corrosion-resistant steel, ideal for use in molds and dies exposed to corrosive environments, such as plastic molding and chemical processing.
- The addition of molybdenum (Mo) enhances its ability to resist pitting and corrosion, especially in chloride-rich environments.
- Hardness:
- This steel can be hardened to around 48-52 HRC (Rockwell Hardness), which gives it good resistance to wear, making it suitable for tooling applications.
- The steel retains good hardness and toughness after heat treatment, allowing it to perform in demanding applications.
- Toughness and Durability:
- DIN 1.2316 offers good toughness, allowing it to absorb impact and stress without cracking or breaking.
- Its excellent durability makes it ideal for use in long-lasting molds and tooling applications.
- Machinability:
- In its annealed state, DIN 1.2316 is fairly easy to machine. However, once hardened, machining becomes more difficult, and specialized tools may be needed to maintain high surface quality.
- The steel also offers good polishability, which is beneficial for applications requiring smooth finishes, such as in molds for plastic injection.
- Heat Treatment:
- DIN 1.2316 can undergo pre-hardened heat treatment to reach an optimal hardness level for molding applications.
- It can also be subjected to tempering to adjust the hardness and increase its strength.
- Weldability:
- The steel has moderate weldability, though special care must be taken during welding to avoid cracking. Pre-heating and post-weld heat treatment are often necessary.
- Applications:
- Injection molding molds: DIN 1.2316 is especially favored in the plastic molding industry, particularly for applications that require resistance to corrosion, like molding aggressive plastics (e.g., PVC).
- Die casting: It’s used in high-performance dies that require corrosion resistance and durability.
- Food industry molds: The stainless steel properties make it suitable for food-related applications that need a high level of hygiene and corrosion resistance.
- Chemical industry: Components that need to withstand aggressive environments (e.g., acids, bases, and solvents).
DIN 1.2316 Steel Rounds:
- Steel rounds refer to circular bar stock made from DIN 1.2316 steel. These rounds can be used in a variety of machining processes such as turning, milling, and drilling to create molds, dies, and other components.
- Sizes can vary depending on the supplier, but they are often available in standard diameters ranging from small sizes (10mm-50mm) to larger diameters, which are ideal for molding and tooling industries.
Summary of DIN 1.2316 Steel Rounds:
- High-quality stainless steel with excellent corrosion resistance.
- Ideal for plastic molds, die casting, and other tooling applications.
- High hardness (up to 52 HRC) for wear resistance.
- Good machinability in the annealed state, but care must be taken during heat treatment and post-machining.
- Excellent polishability, suitable for smooth finishes on mold surfaces.
If you need DIN 1.2316 steel rounds for your project, be sure to choose a reputable supplier that offers the required hardness, sizes, and surface quality to meet your specific needs.
