Benefits Of Using 17-4 PH Polished Round Bar
17-4 PH stainless steel grade is a great combination of carbon, manganese, sulfur, silicon, phosphorus, copper, chromium, nickel, and niobium. As mentioned above, it has multiple benefitting features that are helpful for successful usage in a variety of applications.
But how do these features benefit industries? Let’s find out below.
17-4 PH polished stainless steel round bar is used in applications where such material is required, which doesn’t degrade easily and stops working. In other words, where resistance and durability of machinery are needed.
For example, aerospace and refining machines need to last long without frequent maintenance or repair requirements. That’s why 17-4 PH polished stainless steel round bar is widely used in aerospace and chemical refining industries, as it can resist abrasive chemicals, provides excellent toughness and durability, and has a long service life.
17-4 PH polished stainless steel round bar provides great strength, which is extremely important in refining equipment, processing equipment, and food preparation equipment. These machines have to go through demanding processes where higher strength is required to easily perform the same task repeatedly without any performance errors.
Equipment in chemical processing and marine industries needs to be highly corrosion resistant as it can be exposed to salt water or acid-like substances. And 17-4 PH polished stainless steel round bar provides incredible corrosion resistance due to its high mechanical strength.
17-4 PH Polished Round Bar Applications
Aerospace equipment has to work in a variety of environments and temperatures; hence, it is important to manufacture them using the strongest materials that have corrosion resistance ability and high strength.
17-4 PH stainless steel bars are the best option for the aerospace industry. It provides excellent stress corrosion resistance and tensile strength that are crucial for airplane parts and components.
Paper And Pulp Industries
Equipment in the paper and pulp industry needs to be highly durable and corrosion-resistant in order to effectively perform under the most challenging conditions.
Since they need to operate with water and chemicals, these industries need a good stainless steel grade with strong corrosion resistance and durability to work in the toughest environment. 17-4 stainless steel bars are commonly used in the paper and pulp industry due to their adaptability to numerous positive features.
Food Processing Industry
Hygiene is an integral part of the food industry, and the high chromium content of 17-4 PH grade makes it less prone to corrosion and makes it easy to clean.
17-4 PH stainless steel is the first choice for manufacturing equipment for food processing applications. This is due to the good corrosion resistance ability and surface condition with great toughness and finish of 17-4 PH polished stainless steel bars.
For the production of electricity, nuclear power plants need to use fuel, water, and chemicals. Hence, they need to use strong materials to manufacture their equipment which offers great toughness and corrosion resistance. Hence, the nuclear industry highly prefers to use stainless-steel grade 17-4 PH.
To survive exposure to salty seawater, the marine industry chooses 17-4 PH stainless steel polished bars as they provide superior resistance to corrosion and have high mechanical strength.
Oil And Gas Industry
Usually, oil is obtained at great depths, and such depths are reached with high pressure. Secondly, equipment needs to handle a variety of corrosive media such as hydrogen sulfide gas and carbon dioxide.
17-4 PH stainless steel polished bars are great construction materials that can withstand corrosive media and provide optimum piping performance at great depths.
17-4 PH polished round bars are widely used due to their ideal combination of corrosion resistance, excellent mechanical properties at high temperatures, and high yield strength. This combination makes it ideal for many industrial applications.
