17 4 Ph Stainless Steel Microstructure

This paper deals with the investigation of the microstructure and wear behavior of the stellite 6 cladding on precipitation hardening martensitic stainless steel 17 4ph using gas tungsten arc welding gtaw method.

17 4 ph stainless steel microstructure. It is used in applications where the combination of moderate corrosion resistance and unusually high strength are required. Sheets of 1 9 mm thick metal were deep drawn to the geometry shown in fig. With a higher chromium content than 15 5 ph stainless steel this high strength 17 4 ph offers better corrosion resistance. The indentation results showed that the sample subjected to the lower energy density did not respond well to the conventional heat treatment on 17 4ph stainless steels as expected.

The corrosion resistance of alloy 17 4ph is comparable to 304 stainless steel in most environments and is generally superior to the 400 series stainless steels. 17 7 ph precipitation hardening alloys when choosing an alloy for a particular project it may be helpful to determine your criteria. In b ar and c n 2 482ºc for 1 h after solution treatment. Wrought 17 4 ph steel condition a.

Gas tungsten arc welding gtaw was used to cladding of 17. The microstructure was martensitic with a. Study on the microstructure and mechanical properties of 17 4 ph stainless steel depending on heat treatment and aging time. 17 4 ph stainless steel is widely used in oil and gas industries.

To homogenize the metal the standard heat treatment was used. Stainless steels are widely used in a variety of applications such as food processing petrochemical plants and transportation industries due to their high strength and good corrosion resistance. The 17 4 ph stainless steel that was used in the experiment was obtained according to ams 5604. Bayode esther t akinlabi member iaeng and s.
