3/4" Stainless 17-4PH Annealed Steel Plates

3/4 stainless 17-4PH annealed steel plates are made up primarily of iron. 3/4 stainless 17-4PH annealed steel also contains significant levels of chromium (up to 17.5 percent), nickel (up to 5 percent), copper (up to 4 percent) and manganese (up to 1

3/4" stainless 17-4PH annealed steel plates are made up primarily of iron. 3/4" stainless 17-4PH annealed steel also contains significant levels of chromium (up to 17.5 percent), nickel (up to 5 percent), copper (up to 4 percent) and manganese (up to 1 percent). Columbium, tantalum, carbon, phosphorus, sulfur and molybendum may also be present in trace amounts.

17-4PH annealed stainless steel is available in sheet, strip, plate, bar, and castings. Complete welded assemblies involving components of these various forms are possible. Its unique combination of properties make this alloy an effective solution to many design and production problems.

3/4" 17-4PH annealed stainless steel plate is a martensitic precipitation-hardening stainless steel that provides an outstanding combination of high strength, good corrosion resistance, good mechanical properties at temperatures up to 600°F (316°C), good toughness in both base metal and welds. Short-time, low temperature heat treatments minimize warpage and scaling.
Stainless 17-4PH Annealed plate/sheet has excellent resistance. It withstands corrosive attack better than any of the standard hardenable stainless steels and is comparable to Type 304 in most media. This has been tested in a wide variety of corrosive conditions in the petrochemical, petroleum, paper, dairy and food processing industries, and in applications such as boat shafting. Additional proof of its durability is the replacement of chromium-nickel stainless steels and high-alloy non-ferrous metals by Annealed 17-4PH stainless steel for a broad range of parts requiring excellent resistance to corrosion.

stainless steel processing

The manufacture of stainless steel involves a series of processes. First, the steel is melted, and then it is cast into solid form. After various forming steps, the steel is heat treated and then cleaned and polished to give it the desired finish. Next, it is packaged and sent to manufacturers, who weld and join the steel to produce the desired shapes.

The raw materials that constitute a stainless steel item are placed together and melted in a giant electric furnace. Intense heat is applied rigorously for a period of 8 to 12 hours during this step. Once the melting is complete, the molten steel is cast into desired semi-finished forms. Some of the most common forms or shapes include slabs, blooms (rectangular shapes), billets (these could either be round or square), rods, and tube rounds.

In the second stage, the semi-finished steel shapes undergo a series of forming operations. For instance, the stainless steel is hot rolled (heated and passed through enormous rolls). The blooms and billets mentioned above are converted to bar and wire. The slabs on the other hand are formed into plates, strips or sheets. It is very common to turn semi-finished steel shapes into bars, as it is the most versatile stainless steel form (it comes in all grades and sizes). You have round, square, octagonal, and hexagonal bars, each suitable for a different type of application.

The various stainless steel forms undergo a thorough annealing process during this step. Annealing is another name for heat treatment where the stainless steel is heated and cooled in a controlled environment. The purpose of this heat treatment is to relieve the pent-up stress inside the stainless steel and soften the material to make it more suitable for a wide variety of applications. The people in charge of carrying out the annealing process have to be very careful about the conditions as even the slightest of changes in the temperature, pressure, duration, or cooling rate could result in a faulty product.

During the annealing process, a certain amount of scale appears on the surface of the stainless steel. This scale can be removed using a number of different processes that are collectively known as descaling. Pickling is one of the more common methods of carrying out the descaling process.

The semi-finished, heat-treated, and descaled stainless steel forms are cut into specific shapes in this step. Mechanical cutting is performed with the aid of guillotine knives, blanking, nibbling, and high-speed blades.

Finishing is applied to help the stainless steel product achieve its signature aesthetically appealing appearance. Finishes are also needed to make the stainless steel product smooth and easier to clean, which is a top requirement in sanitary applications.
