How to find the machining difficulty of stainless steel flange
First of all, before the selection of the drill, take a look at the stainless steel flange processing difficult is what? Find out the difficulty can be very accurate, very fast to find the use of the drill bit. What are the difficulties in stainless steel flange processing? Brief stick knife: sta...Read more -
Inspection before heat treatment of die forgings
The inspection before solution heat treatment is the pre-inspection process of the finished product as specified in the forging part drawing and process card for the surface quality and external dimensions after the completion of the forging forming process. Specific inspection should pay attenti...Read more -
Alloy Design
There are thousands of alloy steel grades and tens of thousands of specifications used internationally. The output of alloy steel accounts for about 10% of the total steel output. It is an important metal material widely used in national economic construction and national defense construction. Si...Read more -
Historical development of alloy steel forgings
Every material in the industry has a long history, but today we are mainly talking about the historical development of alloy steel forgings. From the second world war to the 1960s, alloy steel forgings were mainly the era of the development of high-strength steel and ultra-high-strength steel. Du...Read more -
4 processing techniques for SO flanges
With the development of society, the application of flange pipe fittings is more and more extensive, so what is the processing technology of SO flange?Generally divided into four kinds of technology, the following for you to explain in detail. The first used scrap iron pin training embryo, low co...Read more -
The difference between WN and SO Flange
SO flange is an inner hole machined slightly larger than the outside diameter of the pipe, the pipe inserted in the welding.Butt welding flange is the end of the pipe diameter and wall thickness of the same as the pipe to be welded, welding the same as the two pipes. SO and butt welding refers to...Read more -
The Precision Forging Advantage
Precision forging normally means close-to-final form or close-tolerance forging. It is not a special technology, but a refinement of existing techniques to a point where the forged part can be used parts2cmykwith little or no subsequent machining. Improvements cover not only the forging method it...Read more -
50 c8 Ring -Forging quenching.
The ring is Quenching + tempering. The forged-ring is heated to an appropriate temperature (quenching temperature 850℃, tempering temperature 590℃)and kept for a period of time, and then immersed in the medium to quickly cool down. https://www.shdhforging.com/uploads/Forging-quenching.mp4 50 c8 ...Read more -
how are forgings produced
Forging--metal shaping by plastic deformation--spans a myriad of equipment and techniques. Knowing the various forging operations and the characteristic metal flow each produces is key to understanding forging design. Hammer and Press Forging Generally, forged components are shaped either by a ha...Read more -
Hydraulic presses for forging ring blanks
The first forging operation when manufacturing seamless rings is forging ring blanks. Ring rolling lines turn these into the precursors for bearing shells, crown gears, flanges, turbine disks for jet engines and various highly stressed structural elements. Hydraulic presses are particularly well ...Read more -
168 Forging mesh: What are the principles and methods of forging die renovation?
In forging die work, if the main parts of forging die are found to be too badly damaged to be repaired randomly, the forging die should be removed and repaired by the die maintainer. 1.The principles of renovation are as follows: (1) Die parts exchange or part update, must meet the forging die de...Read more
