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

Boiler operation status of the GB/T 5310 20G boiler steel pipe  Some steel companies produce the fake 20G boiler steel pipe cause the huge problems. Because the creep resistance of 20G boiler steel pipe is lower than other steel pipes and the 20G boiler steel pipe is overheated, the 20G boiler steel pipe wall metal overheated for a long time, which results in accelerated creep at high temperature, decreased strength, and finally the early creep burst occurred. During 20G boiler steel pipe fracture analysis, it was found that the macroscopic surface of the 20G boiler steel pipe fracture was covered with thin blue-purple oxide film, which indicated that the temperature of the 20G boiler steel pipe burst was 800℃, and the section was not smooth due to the effect of high temperature oxidation. There is a thick oxide layer on the inner surface of the  20G boiler steel pipe . The structure of the oxide layer has three layers and usually only when the ambient temperature

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
