Heat treatment tempering improvement in St35.8 boiler pipe


With the improvement of people's living standard and the progress of science and technology, the quality requirement of St35.8 boiler pipe is raised gradually. Because the St35.8 boiler pipe has high power, high energy consumption and strong heating ability, the St35.8 boiler pipe must often operate in the environment of high pressure and high temperature.

St35.8 boiler pipe heat treatment specification with the original heat treatment tempering process temperature range is not conducive to standardize staff operation and improve performance stability. According to the temperature control ability of the St35.8 boiler pipe heat treatment furnace, the experiments and performance tests are carried out under the condition of not changing the tempering temperature, but the St35.8 boiler pipe cooling rate should not be too slow, so as to avoid causing the grain size to be coarse and the plasticity to be reduced. For some alloy steels that are difficult to soften after annealing, tempering at high temperature is often used after normalizing. After recrystallization annealing, tempering should be used to further homogenize the microstructure, reduce hardness, and make the carbides in the St35.8 boiler pipe gather properly and reduce St35.8 boiler pipe brittleness. Elimination or subtraction less internal stress. The advantages of this method are that the operation steps of this method are relatively simplified and the technical difficulty of operation is relatively low, so the investment of manpower and material resources is less and the economic cost is low.

Through the research and analysis of heat treatment of St35.8 boiler pipe, a more reasonable heat treatment system which can meet the requirement of customer purchase is found. So if you have any demand of St35.8 boiler pipe, please contact us freely. We can supply the St35.8 boiler pipe with high quality and different sizes. And you can believe our St35.8 boiler pipe can meet your any requirements.

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
