17 4 Ph Stainless Steel Microstructure

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 microstructure.

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 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. The 17 4 ph stainless steel that was used in the experiment was obtained according to ams 5604. With a higher chromium content than 15 5 ph stainless steel this high strength 17 4 ph offers better corrosion resistance.

17 4 ph stainless steel is widely used in oil and gas industries. Gas tungsten arc welding gtaw was used to cladding of 17. To homogenize the metal the standard heat treatment was used. Wrought 17 4 ph steel condition a.

The microstructure was martensitic with a. 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. 168 murr et al. 1 a selective laser melting schematic and pre alloyed atomized powders.

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. Microstructure and microhardness of 17 4 ph stainless steel made by laser metal deposition. Sheets of 1 9 mm thick metal were deep drawn to the geometry shown in fig. 17 7 ph precipitation hardening alloys when choosing an alloy for a particular project it may be helpful to determine your criteria.

It is used in applications where the combination of moderate corrosion resistance and unusually high strength are required. It is also known as 630 stainless steel.
