Product Description:
D6 Cold Work Mould Steel Round Bars DIN1.2436
AISI D6 tool steel is a high-carbon, high chromium tool steel alloyed with tungsten that is characterized by high compressive strength, high wear resistance, high surface hardness and good hardening stability
Specification of D6 tool steel
1.Diameter:60mm~600mm
2.Length:1-6.5m or as customer's request
The chemical composition of D6 tool steels is outlined in the following table.
| Element | Content (%) |
|---|
| Iron, Fe | 83.05 |
| Chromium, Cr | 12.5 |
| Carbon, C | 2.05 |
| Tungsten, W | 1.3 |
| Manganese, Mn | 0.8 |
| Silicon, Si | 0.3 |
Forging
D6 tool steel is heated slowly and uniformly to 700°C (1292°F) and then more rapidly to 900-1050°C (1652-1922°F).
Annealing
D6 tool steel is then annealed at 800-840°C (1472-1544°F) and cooled. Hardness of the steel after annealing will be approximately 225 Brinell.
Stress Relieving
Stresses from D6 tool steel can be eliminated before hardening by heating up to 650-700°C (1202-1292°F), if machining operations have been heavy. The steel is then allowed to cool slowly.
Hardening
D6 steel is pre-heated slowly to 750-800°C (1382-1472°F) and thoroughly soaked. Heating is then continued till the final hardening of 950-980°C (1742-1796°F), followed by air or oil quenching.
Tempering
The steel is heated uniformly and thoroughly at the selected tempering temperature. Double tempering can also be carried out with intermediate cooling to room temperature.
Main applications of D6 tool steels:
- Q:What is the difference between steel and flat steel, round steel and steel?
- On the whole, the square section is square, flat section is rectangular, steel surface after finishing the round steel or steel wire (also called steel, silver bar).
- Q:Could you tell me what is the difference between steel pipe and round steel?
- The middle of the steel pipe is hollow, and the round steel is solid. When compared with the solid steel such as round steel, the steel tube has the same flexural strength and torsion strengthLight weight, is an economic section of steel, widely used in the manufacture of structural and mechanical parts, such as oil drilling pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction.Making ring parts with steel tubes can improve data application rate, simplify manufacturing process, save data and work hours, such as rolling bearings, rings, Jack sleeves, etc., and have been widely used in steel pipe manufacture.
- Q:What is the difference between strip steel and round steel? Where are they mainly used?
- Round steel is a solid strip of steel whose cross section is round. The specifications are expressed in millimeters of diameter, such as "50", which means a round bar of 50 millimeters in diameter. Round bar is divided into three parts: hot rolling, forging and cold drawing. Standard Specification for hot rolled round steel is 5.5-250 mm. Of which: 5.5-25 mm small round bars are mostly supplied by straight strips. They are used as reinforcing bars, bolts and various mechanical parts. Round bars larger than 25 millimeters are used mainly for making mechanical parts or for seamless steel tubes.Mainly used in the manufacture of various tools, cutting tools, moulds and tools (see tool steel), but also a large number of used in the manufacture of various mechanical parts.
- Q:What's the difference between round steel and carbon bound steel?
- Shape is different, round steel round appearance, no grain without ribs, carbon steel surface has engraved or ribbed, so that the round bar and concrete bonding force is small, carbon tie steel and concrete bonding force.
- Q:Is yuan steel round steel?
- 3 strength, steel and other steel with high strength low strength, namely, diameter of the same size as compared with other steel, round steel can bear the pulling force than other reinforced small, but the plastic steel reinforced bar is stronger than the other, there is a large deformation in the break before, and it reinforced the deformation the break before the much smaller.
- Q:What's the difference between Q345 round steel and No. 45 round steel material?
- Q345 is plain carbon steel, and Steel No. 45 is of high quality carbon steel. The biggest difference between them is that the content of sulfur and phosphorus is different.
- Q:What's the difference between a round tube and a round tube?
- Round steel is solid and round tubes are hollow
- Q:Is round steel bar round steel?
- NoRound steel bars refer to hot rolled round steel bars for reinforced concrete. Round bars include high-quality carbon structural steel, round steel, ordinary carbon structural steel round bars, steel bars for prestressed concrete, etc.. Although the shape is round, but the material is different, so steel and round bar is two yards.
- Q:12 of the diameter of the round steel can be M12 out of the thread is not
- No problem。 M12 coarse thread of the pitch is 1.75, the outer circle to be processed to 11.8mm, the thread of the most beautiful shape. If the outer circle is too large, the tip of the tooth is too small and very easy to deform.
- Q:Lightning protection earthing zinc plating flat iron and round steel welding method, need to flat iron wrapped in round steel outside welding?
- Don't need, but the welding seam area not less than round or flat between the relatively small cross section, the weld to coated with anticorrosive paint. Generally speaking, the grounding part does not use steel, galvanized L type flat iron good effect (copper strip and galvanized L type flat iron is not much, just life is long, but the cost is much higher), round only used as grid wiring.
