Welding process of 42CrMo alloy steel pipe in Katalor


42CrMo alloy steel pipe is one of the mainly product in katalor, we have been export 42CrMo alloy steel pipe for more than 10 years. So that we have rich experience in the the steel exporter. And we can produce the high quality 42CrMo alloy steel pipe.

As we all know, 42CrMo alloy steel pipe is widely used in petrocjemical, construction and other industries because 42CrMo alloy steel pipe can resist high temperature, high pressure, corrosion and wear.Welding technology and welding quality is a key link to ensure that 42CrMo alloy steel pipe can effectively exert its due mechanical bearing capacity, which is related to the normal production and operation of enterprises and the normal use of building structures.

The welding process of 42CrMo alloy steel pipe generally includes the preparation before welding and the welding process. As the carbon content of 42CrMo alloy steel pipe is relatively large, it is necessary to polish the gas cutting notch and other mechanical treatment before welding. Otherwise, if not dealt with directly by the welder, 42CrMo alloy steel pipe will be residual stress, resulting in cracks.

Katalor can supply 42CrMo alloy steel pipe with high quality and different size. You can choose the size of 42CrMo alloy steel pipe you need. If you are interested in 42CrMo alloy steel pipe, please contact us for free. We will reply you at first time!

The Straightening of Corten B channel steel To straighten out the bend and shape of Corten B channel steel in rolling, cold, transport, etc., to make the shape correct and straight by straightening so that meet the Corten B channel steel  quality requirements. There are some reasons to impact the straighten of Corten B channel steel. Effect of straightening equipment on quality of  Corten B channel steel . Corten B channel steel straightening generally use 7-roll to 11-roll roller straightening machine. Small Corten B channel steel  using more rolls straightening machine; The roller straightening quality is good, and the roller straightening for large Corten B channel steel is complicated, so it is often used in seven-roll straightener. Effect of straightening technology on quality of Corten B channel steel . Because the Corten B channel steel is an asymmetrical rolled piece, the temperature is low in the thinner part of the...

Elemental Ni has the significant role in JIS G4304 SUS 420J1 steel plate JIS G4304 SUS 420J1 steel plate has certain wear resistance and corrosion resistance, high hardness. JIS G4304 SUS 420J1 steel plate price is the lower class of stainless steel ball. Instruments, transportation tools, household appliances, etc. JIS G4304 SUS 420J1 steel plate is used in the manufacture of parts resistant to atmospheric, steam, water and oxidizing acid corrosion. The addition of element Ni and the increase of Ni content lead to the increase of thermodynamic stability of SUS420J1 alloy, so SUS420J1 alloy has better properties of rust and oxidation resistant medium. With the increase of Ni content, the performance of the reductive medium of SUS420J1 alloy is further improved. It is worth pointing out that nickel is the only important element to improve the stress corrosion of many medium of SUS420J1 alloy.  Nickel also improves the...
