Stainless Steel 15-5

A: 15-5 stainless steel also known as 15-5 PH is an alloy with added features of martensitic precipitation-hardening stainless steel. The alloy includes a composition of around 15% Cr and 5% Ni typifying in high strength, reasonable resistance to chemical corrosion and good toughness.

A: As with the 17-4 PH steel and other 15-5 PH stainless steels, the latter has beneficiation physical man factors such as increased load, elongation, and fracture resistance. The alloy exhibits a yield strength that falls within the range of 100 to 200 ksi, although specific values depend on the heating temperatures. Performance is also good at high temperatures.

A: 15-5 stainless steel comprises predominantly elements such as chromium 14­-15.5 %, nickel 3.5­-5.5 % and copper 2.5­-4.5 %. Thus, strengthening and corrosion resistance are the advantages of using the alloy mentioned Chow et al. These elements are also responsible for precipitation hardening of the material factors and therefore helps improve material mechanical properties.

A: 15-5 PH stainless steel is also known to be utilized in various fields such as aerospace, chemical industry, oil and gas, and so on. The applications include aircraft parts, valve components, pump shafts, fasteners, and fittings. This material is also used in the pulp and paper industry owing to its resistance to corrosion and high strength.

A: Though both 15 – 5 PH stainless steel and 17 – 4 PH stainless steel fall under the category of precipitation hardening steels, toughness in most cases is in favour of 15 – 5 PH than 17 – 4 PH. 15-5 PH contains very little delta ferrite which enhances its ductility and impact resistance. 17-4 PH however sometimes can be benefited with more strength than 15-5 in some experiences.

A: 15-5 PH stainless steel can be subjected to various heat treatment processes to obtain a combination of properties that is quite different from the properties associated with the steel in its as-received machined state. More common conditions include H900, H925, H1025, and H1150; all of which aim at providing different levels of strength and toughness. This material is usually zero heat treated before aging in order to obtain the required characteristics.

A: The density of 15-5 PH stainless steel is close to around 7.8 g/cm, the melting point is close to the range of 1404-1440°, and specific heat of 460 J/kg·K at 20°C. At 20ºC, its thermal conductivity is close to 18 W/m·K and its electrical resistivity is close to 83 µΩ·cm at room temperature.

A: 15-5 PH stainless steel has good resistance to corrosion in a wide range of environments. Works in mildly corrosive to moderately corrosive environments such as benign atmosphere, freshwater and many chemical process environments. I t works better than some austenitic stainless steels in less corrosive environments, but this may be its Kanya gulper in highly corrosive environments.

A: 15-5 PH stainless steel can be supplied in form of bar, plate, sheet, forgings and other product forms. Bar stock is mostly supplied in diameters of 0.25 up to 12 inches. The thickness of standard plates can range between 0.25 inches and 6 +1 inches thick. Standard sheet products are available in thicknesses of between 0.015 inches and 0.250 inches.

A: There are several methods of processing 15-5 PH stainless steel. This material can be machined while in the annealed condition as well as after hardening, although the latter is likely to result in greater tool wear. The alloy can be joined by the ordinary means of welding but the joints should be protected from cracking. Standard metal forming techniques are also available for this material.
