253MA Stainless Steel Tubes

253MA stainless steel tubes
It is a heat-resistant Austenitic stainless steel tube designed for applications requiring high creep strength and good corrosion resistance.
 
The chemical composition of the 253MA stainless steel tube is balanced, which makes the 253MA stainless steel tube have the most suitable comprehensive performance in the temperature range of 850 °C-1100 °C, high oxidation resistance, and the scale temperature is up to 1150 °C; extremely high creep resistance Variability and creep rupture strength; good resistance to high temperature corrosion and resistance to brush corrosion in most gaseous media; high yield strength and tensile strength at high temperatures; good formability and Solderability and sufficient machinability.
 
In addition to the alloying elements chromium and nickel, the 253MA stainless steel tube also contains a small amount of rare earth metal, which significantly improves its antioxidant capacity. Nitrogen is added to improve creep properties and make this steel tube a complete austenite. Although the chromium and nickel contents are relatively low, this stainless steel tube has many of the same high temperature characteristics as the high alloyed alloy steel tube and the nickel base alloy steel tube.

Heat Treatment
Solution Treatment (Annealing) Heat to 1050-1150°C and cool rapidly. It is recommended that the material be solution treated after 10-20% cold work to achieve maximum creep strength in service.
This grade cannot be hardened by thermal treatment.
 

Manufacture
253MA stainless steel tubes are manufactured by seamless process or by electric resistance welding process
 
253 MA Stainless steel tube is readily fabricated by standard commercial procedures. In comparison to carbon steel, stainless steels are tougher and tend to work harden rapidly. However, with positive feeds and slow speeds combined with abundant cutting fluid this alloys tendency to work harden may be minimized.
 
253 MA Stainless steel tube can be welded using conventional welding processes. Filler metal should be of similar composition for maximum weld integrity and properties
