Stainless steel is one of the things people come across in everyday life due to its versatile uses. It is used in many industries like paper, nuclear, oil & gas, chemical, renewable energy, and many more and the main reason for this vast array of industrial uses is because Stainless steel is a corrosion-resistant alloy of iron, chromium and, in some cases, nickel and other metals.
Stainless Steel is the green material par excellence because it is infinitely & completely recyclable. Some stainless steel is also known for its high yield strength and in addition, stainless steel does not leach compounds that might alter its composition after being in contact with water.
Stainless steel comes in many forms and is used in different ways according to the needs and one of them is 17-4 PH stainless steel, it is one of the most commonly used stainless steel in Petrochemical, aerospace, paper & nuclear industries as well as it is used in the manufacturing of turbine blades, food processing equipment, and marine vessels. The main advantage of using 17-4 PH stainless steel is that it is resistant to the effects of corrosion.
Stainless Steel 17-4 PH is a chromium-nickel grade of stainless that may be hardened by a single low-temperature precipitation-hardening heat treatment. Type 17-4 PH stainless steel is the most common type of martensitic PH stainless steel. Martensite is basically a steel crystalline structure that is hard. It transforms at low temperatures of 250 degrees centigrade into PH stainless steel.
When 17-4 PH stainless steel goes through the precipitation hardening process, it gets one-step heat treatment at a temperature in the range 900°F (482°C) to 1150°F (621°C) depending on the combination of strength and toughness desired.
17-4 PH stainless steel has good machinability in the annealed condition – similar to that of stainless 304. Machining does become more difficult after hardening heat treatment. Carbide or high-speed steel tools can be used along with standard lubrication.
Some of the Physical and mechanical 17-4 PH stainless steel properties of the 17-4 PH stainless steel are mentioned below:
|Melting Range||2560-2625 °F||1404-1440 °C|
|Specific Heat||0.11 Btu/lb.-°F||460 Joules/gg-K|
|Specific Density||0.282 lb./in3||7.8 g/cm3|
|Ultimate Tensile Strength||23,300 psi||160 MPa|
|Yield Strength (0.02%)||16,680 psi||115 MPa|
Advantages of using 17-4 PH Stainless Steel:
As of now, there is no doubt that 17-4 PH stainless steel is providing many benefits from corrosion resistance to good mechanical properties and of course, high yield strength this makes it one of the most preferred alloys for many industries.
