DIN 2344 Steel

DIN 2344 ESR

ESR is the most refined material with the traditional VD route. The quality of material increase the toughness, highly increase the micro- cleanness level.
Highly recommend the use of 2344 ESR grade for Aluminum Pressure Die Casting & other component subjected to high working temperatures and high pressure strength. DIN 2344 is fully ultrasonic inspected with 100% positive results as per NDT standards.

DIN 2344 Steel Properties

High hot-wear resistance and hot tensile strength as well as good toughness, thermal conductivity and insusceptibility to hotcracking. Can be water-cooled to a limited extent.

1.2344 Physical Properties

Depending on the precise composition and heat treatment of the DIN 2344 steel, the physical attributes may differ somewhat. It's always advisable to refer to the manufacturer’s specifications for accurate information.

Heat Treatment & Processes:

Heat treatment:

Preheating DIN 2344 tool steels to 816°C (1500°F). The temperature is then instantly raised to 1010°C (1850°F) and held there for 15 to 40 minutes before being applied to the steels. After that, the steels are air-quenched.

Hardening:

DIN 2344 tool steel should be hardened by cooling in still air since it has a very high degree of hardenability. If a salt bath or controlled environment furnace is not available, pack hardening in wasted pitch coke is advised to reduce decarburization. The temperature used ranges from 1800° to 1850°F, depending on the size of the part.

Forging:

Heat must be applied evenly and gently for forging. Reheat as often as necessary while soaking through at 1900°–2000°F; cease working when the temperature falls below 1650°F. After forging, cool gradually in a furnace, lime, mica, or dry ashes. After forging, DIN 2344 should always be annealed.

Stress Relieving:

After machining, welding, or other high-temperature procedures on DIN 2344 steel, stress relieving is a heat treatment procedure used to lower internal tensions and enhance dimensional stability.

Normalizing:

Do Not Normalize.

Annealing:

DIN 2344 tool steels are annealed in the furnace at 871°C (1600°F) and then slowly chilled at 4°C (40°F).

Cold working:

Cold working may be carried out on DIN 2344 tool steels using conventional methods.

Nitriding:

Nitriding is used to give DIN 2344 tool steel a hard surface covering. The steel has a strong resistance to corrosion and abrasion as a result. Nitriding also increases corrosion resistance. Nitriding in ammonia gas at a temperature of 525°C results in surfaces with surface hardness ranging from 1000 to 1250 HV. Before being nitrided, the tool has to be hardened and tempered to a temperature that is around 50°C higher than the nitriding temperature.

Welding:

DIN 2344 tool steels may easily be joined together using a variety of welding techniques, such as gas tungsten arc welding, shielded metal arc welding, and gas metal arc welding.

Quenching:

Using a quenching medium such as air, oil, water, or polymer solutions, the DIN 2344 steel is quickly cooled to room temperature or lower. The target hardness, distortion control, and component shape are only a few examples of the variables that affect the quenching medium selection. The temperature range required for quenching steel is (500-550 °C).

Tempering:

Quenching leaves the steel with an extremely rigid yet fragile structure. Immediately following quenching, the hardened DIN 2344 steel is commonly tempered in order to increase toughness and relieve internal tensions. Reheating the steel to a certain temperature range—typically between 500°C and 650°C (1202°F)—and maintaining it there for a predetermined amount of time is known as tempering. In fact, this procedure aids in lowering the steel's hardness, boosting its toughness, and improving its overall performance. A hardness of 53 to 38 HRC is achieved by tempering DIN 2344 tool steels between 538 and 649°C (1000 and 1200°F). These steels can also undergo double tempering once per hour at the chosen tempering temperature.
