Almost every industry uses stainless steel turned pieces, which give tools, storage containers, automobile parts, and other items strength and corrosion resistance. A steel alloy called stainless steel has at least 10% chromium in it. Chromium is added to steel to give it a flawless surface polish and remarkable corrosion resistance that surpasses that of carbon steels. Key characteristics of it include.
- High strength
- Excellent heat resistance
- Excellent corrosion resistance
- Superior impact resistance
- Self-protective
- Typically doesn’t require surface finishing
CNC turning is a method that involves cutting material to make rounded shapes, and it is used to generate stainless steel turned parts. Reading Plastic specializes in multi-axis lathe operations with tolerances as tight as.001 inches. Additionally, we provide variable pitch, ANSI, and metric precision threading.
There are five types of stainless steel:
Austenitic
Despite being prone to stress corrosion cracking, this kind is non-magnetic, highly formable, and corrosion resistant. It can be heat treated but not cold worked. Bolts, nuts, bushings, valves, and aircraft fittings are typical applications. The most popular stainless steel alloys, 304 and 309, are austenitic stainless steels of the 200 or 300 class. Stainless steel 309 is tougher than 304 and has superior corrosion resistance, making it perfect for high-temperature applications up to 1900°F. Additionally, it is rather simple to machine.
Ferritic
In comparison to austenitic grades, this type is magnetic and has inferior ductility and corrosion resistance. Heat exchangers, furnace parts, and automobile fasteners are frequently made with it because of its great resistance to stress corrosion cracking. The 400 series of ferritic stainless steels includes the 409, which has excellent corrosion resistance at high temperatures and is simple to process. Made from stainless steel .
Martensitic
This type is magnetic and heat treatable; it is stronger than ferritic grades but less corrosion resistant. It is frequently utilized in bushings, rivets, jet engine components, and aircraft fittings. Martensitic stainless steels, such as type 410, which has 11.5% chromium, are found in the 400 and 500 series. Because of this, it is remarkably resistant to acidic and chemical corrosion. For nuts and bolts, stainless steel 410 is frequently utilized. both surgical tools and machinery for processing petroleum.
Precipitation Hardening Grade
These grades can be heat treated and are typically more stronger than austenitic varieties. They continue to be largely strong in high temperatures. They are frequently utilized to build structural components for aircraft and military equipment and are also known as PH Type stainless steel.
Duplex
A hybrid of austenitic and ferritic steels, duplex stainless steels feature exceptionally high strength and stress corrosion cracking resistance. They are found in UNS grades and are often used to make chemical processing equipment and pressure vessels. A common duplex stainless steel, S32550, is known for high corrosion resistance and impressive strength. It is frequently used in marine equipment, pumps and shafts.
