Characteristics Of Stainless Steel Screw Price
Stainless steel screws are used in a wide variety of applications. It’s essential to understand the characteristics of this metal before choosing a particular screw for your project. These characteristics can make a big difference in the strength and performance of your screws.
Manufacturing Process of Stainless Steel Screws
During heat treatment, stainless steel undergoes a series of metallurgical responses. The results of these reactions are an increase in strength and hardness. These alloys are used for a wide range of applications. Also, they are available in various Rockwell hardness levels. These alloys have good weldability and corrosion resistance and are malleable. They can be annealed or cold-worked. Also, the hardening process is very complex. It starts with a solution-annealed strip. This is then cold worked at room temperature. The next step is quenching. This can take place in water, oil, or air. The quenching step is crucial because it will cool the metal to room temperature. This allows for the formation of finer grain size.
AISI 304 Stainless Steel Screws
Stainless steel 304 screws are most commonly used in applications where there is a need for a durable, corrosion-resistant material. These fasteners are available in many surface finishes, including self-colored, hot dip galvanized, and zinc coated. They are also effortless to weld and finish, affecting the Stainless Steel Screw Price. They are widely found in various household and industrial applications, such as appliances, kitchen benches, chemical processing equipment, and sinks. 304 stainless steel is an austenitic material, meaning it has a low carbon content. It has a minimum tensile strength of 515MPa. It is susceptible to sensitization at the grain boundary of the metal when exposed to sulfuric acid. It is considered an economical option for most environments, but it is not as corrosive as 316, which makes it less desirable for specific applications.
Other Grades of Stainless Steel Screws
316 Stainless Steel Screws
316 stainless steel is tough and has the highest tensile strength of any metal in its class. The best part is that you can buy good stuff at a reasonable price. Most people opt for the latter. 316 stainless steel screws are made to last. A quick web search will give you a list of trusted manufacturers and distributors with an impressive portfolio of quality stainless steel fasteners. If you’re in the market for a slick sleeve or a new piping system or are simply looking to spruce up your home or office, you’re in luck.
A2 Stainless Steel Screw
Stainless steel fasteners are available in different grades, and the most commonly used are A2 and A4. Besides being strong, these fasteners are non-magnetic and have good corrosion resistance. They are also popular in the medical and marine industries. Both grades are made from the alloy 18% chromium and 8% nickel. These alloys provide an excellent finish and are widely used for welding steels. Grade A4 also contains molybdenum which improves its corrosion resistance and prevents pitting.
The A2 and A4 grades are austenitic, meaning they do not undergo heat treatment. The chromium in the material also contributes to strength and corrosion resistance. The minimum tensile strength of this grade is 700 MPa. It is also resistant to corrosion and salt spray. Nonetheless, this fastener is unsuitable for active power-train components or suspension systems.
Duplex Steel Screws
Duplex steels are known for their higher strength and toughness than austenitic stainless steels. They also have better corrosion resistance. There are many applications for duplex stainless steel screws. Also, these include chemical and process equipment, flowlines, and offshore platforms. They are also used in ballast water systems and fire fighting systems.
Duplex stainless steel screws are two-phase alloys with an equal mix of ferritic and austenitic phases. The austenitic phase also referred to as a’, is a chromium-rich b.c.c. step that strengthens the ferrite. The a’ step can also develop by nucleation or spinodal decomposition. Also, there are many types of duplex screws. These include socket head caps, blind rivets, and threaded and hex head bolts. They are also lighter than other stainless steel. They are suitable for demanding applications.
