Introduce the welded joint of SA572 Gr.50 steel plate


SA572 Gr.50 steel plate is a kind of typical low alloy high strength structural steel. It can not only improve the overall strength of the tower, but also obtain good toughness, greatly reduce the weight of the tower body. But the hardening tendency of the SA572 Gr.50 steel plate is greater, the hardness is higher, and the crack tendency is large after welding.

How to improve the properties of welded joints and how to make the strength and hardness of welded joints when the SA572 Gr.50 steel plate is made of tower frame is the key problem to be popularized and applied in tower manufacturing.

The microstructure of the weld can be effectively refined by microalloying of Ni element in the SA572 Gr.50 steel plate weld joint from the flux coating to the SA572 Gr.50 steel plate. In a certain range of Mn content, with the increase of Ni element content in SA572 Gr.50 steel plate, the microstructure of weld is gradually refined, the content of needle-like ferrite is obviously increased, the impact property of weld is obviously enhanced, and the strength and hardness of SA572 Gr.50 steel plate welded joint are also improved.

If you have any requirements about SA572 Gr.50 steel plate, please contact us. We are improving SA572 Gr.50 steel plate welded joint all the time. We have professional team to produce the SA572 Gr.50 steel plate. So you don’t worry about the quality. We will give you the best price.

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
