Heat treatment of welded P9 Steel Pipe


Heat treatment of welded P9 Steel Pipe has three forms:

The first is on-line weld heat treatment. Add 1 group or array of power frequency induction heating device before sizing, only heat weld zone, do not involve P9 Steel Pipe matrix, improve weld structure, eliminate welding stress as the goal, but can not solve the whole P9 Steel Pipe. The problem of organizational uniformity.

The second is on-line full P9 Steel Pipe heat treatment. Add 2 sets or more of intermediate frequency ring induction heating device before sizing to heat the P9 Steel Pipe, heating to the temperature needed for on-line normalization in a short time (about 900 ~ 920 ℃), holding for a certain time, air cooling to when the P9 Steel Pipe temperature is below 400 ℃, it is normally cold. As a result of the treatment of the whole P9 Steel Pipe, its organizational uniformity has been improved.

Last is P9 Steel Pipe heat treatment in an off-line ordinary furnace. The P9 Steel Pipe cut off after sizing can be normalized in the roller bottom heat treatment furnace, the heating temperature and running speed in P9 Steel Pipe can be adjusted, and the automatic control can be carried out by computer.

If you have any questions about P9 Steel Pipe, you can contact us freely. We can supply P9 Steel Pipe with high quality and different size. If you need P9 Steel Pipe stock or P9 Steel Pipe machining service , you can contact with Katalor, we can make the P9 Steel Pipe quotation according to your demands.

ASTM A517 steel belongs to the boiler steel plate

ASTM A517 steel (also called ASME SA517 standard) is a kind of high-strength quenched and tempered alloy steel plates intended for use in fusion welded boilers and other pressure vessels. The steel shall be killed and shall conform to the fine austenitic grain size requirement. Under this specification, the plate thickness determines the grade selection and the mechanical properties.   A517 grade A steel pates 2.5" in thickness and under, will have minimum Yield Strength of 100 ksi.  A517 grade b steel plates over 2.5" in thickness will have a minimum Yield strength of 90 ksi.  Typical applications include unfired vessels and tanks. ASTM A517 Grade A plates are Pressure Vessel Plate and supplied in the as-rolled condition. The ASTM A517 Gr. A plate may be ordered normalized or stress relieved, or both. ASTM A517 Grade H are Pressure Vessel Plate and supplied in the as-rolled condition. The ASTM A517 Gr. H Plate may be ordered normalized or stress relieved, or both. AS

Katalor has more useful S235JR steel plate information S235JR steel plate  is a kind steel grade and it is mainly used for steel structural buildings, frames and other steel body under the standard of EN 10025-2.  S235JR steel plate  is for low temperature impacting test under zero centigree. Katalor steel Industrial specialized in S235JR steel plate  in china many decades years. The composition characteristics of S235JR steel plate  are low carbon, less than 0.20%, low alloy and total alloy element less than 3%. Low carbon content in S235JR steel plate  steel is to meet the technical requirements of plasticity, toughness, weldability and cold deformation of S235JR steel plate  used for engineering structural parts. The S235JR steel plate  has Mn as the main additive and conforms to the resource characteristics of our country. Mn not only has a significant strengthening effect on ferrite , but also reduces the cold and brittle temperature of the S235JR steel plate , and

How to storage the EN 10025-2 S235J0 channel steel correctly Generally, the storage of Katalor EN 10025-2 S235J0 channel steel will be placed in the storehouse. Although this environment is favorable to its storage, it should be noted that EN 10025-2 S235J0 channel steel quality will also be affected by its placing method. Therefore, when placing EN 10025-2 S235J0 channel steel, there are several things to pay attention to: First, the same type of EN 10025-2 S235J0 channel steel is stacked separately according to the order of storage, so as to facilitate the implementation of the principle of advanced first issue. Moreover, the principle of stacking requires that under the conditions of stable palletizing and ensuring safety, the stacking should be carried out according to varieties and specifications. Different materials of EN 10025-2 S235J0 channel steel should be palletized separately to prevent confusion and mutual corrosion. Second, the stacking he
