Heat treatment of JIS G 4304 SUS 304L stainless steel plate


JIS G 4304 SUS 304L steel plate belongs to stainless steel plate under the Japanese material standard , and it is a brand of stainless steel produced in accordance with ASTM standards. Katalor is a professional steel supplier to produce the JIS G 4304 SUS 304L stainless steel plate in China. Then we will introduce the heat treatment of the JIS G 4304 SUS 304L stainless steel plate.

The heat treatment of JIS G 4304 SUS 304L stainless steel plate include the solution treatment, stress-relief annealing and stabilizing treatment.
The aim is to dissolve the carbides fully and retain them in austenite at room temperature, so that the single-phase austenite structure can be obtained at room temperature, and the JIS G 4304 SUS 304L steel plate has the highest corrosion resistance.

In order to eliminate the residual stress after welding and to eliminate the sensitivity of JIS G 4304 SUS 304L steel plate to stress corrosion treatment is usually carried out at a higher temperature. The heating temperature is generally not lower than 850 ℃. Cooling mode, JIS G 4304 SUS 304L steel plate containing titanium or niobium may be cooled directly in air; for steel without titanium or niobium, water should be cooled to 500 ℃ before cooling in air.

In order to prevent JIS G 4304 SUS 304L steel plate of titanium and niobium from being welded or treated by solution, the intergranular corrosion resistance of austenitic stainless steel with titanium and niobium decreases due to the decrease of some elements. So the JIS G 4304 SUS 304L steel plate should be heated to a certain temperature and then cooled slowly.

Katalor only provide the JIS G 4304 SUS 304L steel plate with high-quality for our customers. If you have any requirements of the JIS G 4304 SUS 304L steel plate, you can contact us freely. We will solve all the questions about JIS G 4304 SUS 304L steel plate for you. We are glade to cooperate with you.

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
