18-8 SS Fastener vs. 304 Stainless Steel Fastener

 If you have requirement of fasteners, you have numerous possibilities. fasteners are available in a variety of sizes, threads, heads. However, before you begin to limit down your options, you must first determine which fastener to purchase. Although 18-8 fasteners and 304 SS fasteners are two of the most common fasteners on the market, there are a few distinctions between them that might affect the long-term performance of your final product.

18-8 Stainless Steel fasteners

The composition of this iron alloy gives it its name. It is made with approximately 18% chromium and 8% nickel and covers a family of fittings including 302, 304, 305, and 384 stainless screws. All of these fittings begin with 18-8 stainless steel fastener before being upgraded with other alloys. fasteners constructed of 18-8 stainless steel are nonmagnetic and have high rust and corrosion resistance.

304 Stainless Steel

This austenitic stainless steel 304 alloy is the most extensively used in the AISI (American Iron and Steel Institute) 300 series. It has the chromium and nickel composition of 18-8 stainless steel but also contains up to 0.08% carbon. It also has several features in common with 18-8 stainless steel, such as resistance to corrosion and oxidation. The presence of carbon gives this alloy greater strength and hardness, distinguishing it from other alloys.

The Applications of 18-8 SS vs. 304 SS

Fasteners constructed of 18-8 vs. 304 stainless steel provide various advantages due to their varied chemical structures. Consider the following applications for 18-8 vs. 304 stainless steel before making your purchase:

18-8 Fastener: Because of its chemical makeup, 18-8 grade stainless steel is used in a wide range of industries. This alloy's fasteners will operate well in chemical, high-temperature, and high-moisture conditions. These screws will react to chlorides, such as salt, and are hence not suitable for use in maritime applications.

304 SS Fastener : 304 stainless steel fastener has a slightly different alloy composition. In the 300 series, this alloy has some of the best corrosion resistance. The additional hardness provided by the carbon, along with the advantages of chromium and nickel, makes these screws popular for HVAC applications as well as construction applications such as deck, gutter, and roofing installation.

A4-70/A4-80 Stainless Steel Hex Bolt

Image
  Stainless Steel Hex Bolt 316 or 316L austenitic stainless steel is used to manufacture the A4 70 and A4 80 bolts. The letter A denotes cold forged austenitic stainless steel fasteners. Dimensional control is governed by numerous standards. A4-70 hex bolts and other fasteners are available in sizes ranging from  M10 to M100. Depending on the material qualities, the A4-80 Stainless Steel Bolt can be found in grades ranging from 1 to 5. The bolt is composed of cold wrought austenitic stainless steel and is acid resistant. Hex bolts are chosen for usage with heavy machinery due to their geometric design, making them stronger. One tenth of the tensile strength of 70 MPa is represented by the name. The A4-70 stud bolt contains a stud and is frequently used in piercing application. These fasteners are suitable for situations involving high temperatures. They can work at temperatures as high as 870°C. The corrosion resistance of A4 70 and A4 80 stainless steel hex bolts is also goo...

   Information  of Stainless Steel 304 Bolt Due to its chemical components, stainless steel 304 is also known as 18-8. The grade 304 stainless steel contains 18 percent chromium and 8% nickel, among other components (18-8). These bolts are also available in the grades 302, 302HQ, 303, and 305. These have distinct characteristics and a well-defined chemical makeup. One of the greatest materials for producing a series of bolts is stainless steel 304. Because of its corrosion resistance properties, each material differs from the next. The stainless steel 304 grade is resistant to a certain environment and chemicals due to a number of variables. Bolts made of steel 304 are non-magnetic and have greater corrosion resistance. The cold-working method hardens the result due to the material quality.   Stainless Steel 304 Bolt Mechanical Properties : The density (8 g/cm3), melting point (1450 C), and flexibility of stainless steel 304 bolts are all excellent (193 Gpa).

Stainless Steel Hex Bolts

Image
Stainless Steel Hex Bolts  A hex bolt is a fastener with a six-sided forged head and a machine thread that is used in connection with a nut to generate the nut and bolt combination which is used to hold a joint on both sides of a body. This works in a similar way to a screw with a thread, except it rotates on its own axis to penetrate and secure the surface of Nuts. Cap screws and equipment bolts are other names for hex bolts. They normally range in diameter from  1/2" to 12". They can be up to 30" long. The thread length changes according to the length of the bolts. Thread length of hex bolts that are 10" or longer is approximately 6". Dimensional limitations are good with powerful hex bolts and structural bolts. A few more non-standard sizes can also be customised to meet the needs of varied applications. Stainless Steel Hex Bolts have a wide range of applications as fasteners in wood, steel, and other materials. They are widely used in the construction of b...
