Heat Treatment
DIN 1.2379 steels alloy should be preheated very slowly to 815 (1500 F) and the temperature can be increased to 1010oC (1850 F). Then held at 1010oC (1850 F) for 20 to 45 minutes and air-cooled (air quenched).
Annealing
Annealing of 1.2379 tool steels material should be done at 871 to 898 C (1600 to 1650 F) followed by slow furnace cooling at 4.4 C (40 F) per hour or less, after which cooling rate could be increased. At the same time, must do something to prevent excessive carburization or decarburization.
Stress Relieving
Heat it slowly to 1050 -1250 F, allow to equalize, and then cool in still air(Strain Relieving)
Preheat Prior To Hardening
Preheat slowly to 1350 -1450 F and hold at this temperature until steel 1.2379 steel material is uniformly heated.
Hardening
After thorough preheating, heat to 1800 -1850 F. Hold it at the hardening temperature until it is completely and uniformly heated.
Quenching
DIN 1.2379 steel tool material is an air hardening steel and will develop hardness on cooling in still air. To avoid scaling and prevent decarburization on the surface, controlled atmosphere or vacuum furnaces are recommended. Parts should be allowed to cool to 150F, or to where they can be held in the bare hand, and then temper immediately.
Tempering
The tempering temperature on material 1.2379 steel may be varied according to the desired hardness. 1.2379 steels can be tempered at 204 C (400 F) for achieving Rockwell C hardness of 61 and at 537 °C (1000 F) for a Rockwell C hardness of 54.
Compare
Chinese Cr12Mo1V1 steel, American D2 steel, Japanese SKD11 steel, the chemical composition of them is the same, but the performance is very different. After heat treatment, the color of Cr12Mo1V1 is a little orange-red, and the deformation would be large. It is easy to fracture during use. And the hardness of D2 steel is higher than SKD11 steel, but the toughness is not better than SKD11 steel. SKD11 steel is light and smooth, with the best overall performance.
D2 Steel Forging
Heating for forging of AISI D2 tool steel should be done slowly and uniformly. Soak through at 1850 -1950 F and reheat as often as necessary, stopping work when the temperature drops below 1700 F(926 C). After D2 mold steel forging, cool slowly in lime, mica, dry ashes or furnace. D2 steel should always be annealed after forging.

D2 steel round bar and plate can be used to produce cold work mold with a large cross-section, complex shape, high impact force, and high wear resistance. It also is called DIN 1.2379 and JIS SKD11 steel. It is a high-carbon and high-chromium cold work mold steel. It is widely used in the world. It has high hardenability and the high-temperature oxidation resistance is good. The anti-corrosion ability is good after quenching and polishing, and the deformation is small after the steel heat treatment.
D2 Steel Application
1.2379 steel is used for blanking or forming dies, thread rolling dies, shear knives, food-processing knives, gauges, punches and etc.

Stainless steel hydrogen dissolving rods are a specialized material commonly used in various industries for the dissolution of hydrogen gas in liquids. The rods are made from high-quality stainless steel and designed to efficiently dissolve hydrogen gas into liquids, such as water, to produce high-purity hydrogen gas for use in a range of applications.
TOPTITECh stainless steel diffusion stone is made of food-grade stainless steel material and can be used in many kinds of hydrogen water machines. Sintered integration does not fall off, and is anti-corrosion, heat-resistant, and anti-pressure. Compared with PE, stainless steel material is more durable and steady, with uniform porosity and high filtration. They can be utilized for high concentration hydrogen generators, portable home hydrogen absorption accessories, hydrogen machines, and other things.
Parameters
Material: Stainless steel
Dimensions: 12*180mm
Pore size: 20 microns
Porosity: 30-50%
Features
High durability: Stainless steel hydrogen dissolving rods are highly durable and can withstand harsh operating conditions.
Efficient hydrogen dissolution: The unique design of stainless steel hydrogen dissolving rods allows for the efficient dissolution of hydrogen gas into liquids, producing high-purity hydrogen gas for use in a range of applications.
Corrosion resistance: Stainless steel is highly resistant to corrosion, which is important when working with hydrogen, as it is a highly reactive gas that can corrode many materials. This makes stainless steel a suitable material for use in hydrogen dissolution, as it can withstand harsh operating conditions and prevent corrosion.
Easy to use: Stainless steel hydrogen dissolving rods are easy to use and require little maintenance, making them a cost-effective and reliable solution for hydrogen gas production.
