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.

PSQ Pump Shaft Quality under the product
DH produces PSQ bars in both Austenitic as well as Martenistic grades.
Austenitic stainless steels are most commonly used. Austenitic stainless steel pump shafting is not magnetic; due to its high nickel and chromium composition, it is extremely resistant to corrosion. In addition, austenitic stainless steel pump shafting provides excellent mechanical properties. Heat treatment cannot be used to harden austenitic stainless steel pump shafting, although it can be hardened considerably by cold working.
Grades Available in Austenitic Steel:-
AISI-410
AISI-416
AISI-420
DH produces PSQ bars with superior finish and straightness tolerance by an additional process using modern techniques and state-of-art machinery and types of equipment including special finishing machines to give a smooth and mirror finish surface. Thus wear-free running of the impellers is ensured. DH also provides chamfering at 30- 45 degrees as per customer requirements.
The bars thus produced undergo stringent quality and inspection test in order to ensure the exact technical requirements have adhered during the production as per O.E.M. specifications.
Thereafter the bars are wrapped in HDPE sheets and then stuffed inside export-quality wooden boxes as per the specific requirements of the customer. DH also provides other types of packing like tube packing of each bar, putting 3-4 rubber/plastic "O" rings throughout each bar as per specific requirements from their customers. The details of such packing are precisely explained in our Packing segment under this website.
Specification:
Size Range : 10mm-70mm
Diameter Tol. : h9, h8
Ovality: 1/2 the diameter tolerance
Straightness: Upto 0.5mm per 1 meter
Length : 2.5 meters - 6 meters
Surface : Smooth / Mirror Finish
The common application of PSQ Bars:-
The PSQ bars are commonly used at following Industry levels:-
Pneumatic and Hydraulic Cylinder Shafts
Textile Machinery Shafts
Piston Shafts
Precision Shafting
Chemical Pump Shafts
Type 304 is the most versatile and widely used stainless steel. It is still sometimes referred to by its old name 18/8 which is derived from the nominal composition of type 304 being 18% chromium and 8% nickel
One of the top AISI 304 Round Bars Manufacturer, Suppliers, and The aerospace sector relies heavily on 304 Round Bars, which are also crucial for transportation and constructions like window and building fade frames.
Stainless Steel Black Round Bar coated with black oxide are nothing more than metallic bars. As a conversion coating, black oxide can be applied to many alloys, including ferrous materials, copper and copper-based alloys, stainless steel, Alloy Steel Black Bar, powdered metal, and zinc.
Manufacturers prefer Astm A276 Stainless Steel Black Bar for this type of coating because it may supplement mild corrosion resistance in the alloy. Second, Industrial Black Bar & Rods are given an aesthetic makeover by being dyed a darker shade.
Last but not least, some applications require dull components. The layer of these bars can be pulled down by applying a coat of black oxide. Light is reflected more strongly by nickel-based alloys.
The use of black oxide on Nickel Alloy Black Bar reduces light reflection. Carbon Steel Black Bar requires an emulsified black oxide coating with a substrate such as oil or wax to achieve maximum corrosion resistance.
Comparatively to other coatings, black oxide coat on Duplex Black Bar has a minimal build up. Black oxide can be applied to ferrous materials, such as SS Black Square Bar, using any of the following methods: hot black oxide, mid-temperature black oxide, or cold black oxide. Caustic, oxidising, and sulphur salts are used to blacken 300 and 400 series SS Black Rods and precipitation hardening alloy 17-4 PH.
