When it comes to threaded rods, two sayings come to mind:
- One size doesn’t fit all.
- Not all threaded rods are made equal
Threaded rods are made of a variety of materials that are specifically engineered for high-temperature applications. Their use depends on the application chosen and the industry for which it is used.
One of the most popular steel used in the manufacturing of threaded rods is grade B7 steel. It is highly demanded because of its tensile strength and excellent heat and corrosion resistance.
If you’re in the market for threaded rods, there are a variety of materials and grades from which to choose.
Steel grade threaded rods are one of the most common and low carbon steel is the most common of this material. It is used in all aspects of the threaded rod industry because they are so versatile.
There is a variety of low-grade carbon steel that’s used that satisfy minimum tensile and yield strength requirements within the ASTM A307 standards. They include 1008, 1018, and 1022.
What’s so great about low carbon steel is that it’s easy to shape due to its malleability. Therefore, it is an ideal material for bending and manufacturing products including U-bolts. It is also weldable. So it is used in a number of different industries.
Specifications followed for low carbon steel include:
- ASTM A193/B7
- ASTM A193/B7
This specification is for bolts that are designed to anchor structural supports into concrete foundations. The spec involves three grades each of which feature increased yield strengths. These grades include Grade 36, which has a yield strength of 36 ksi; Grade 55, which has a yield strength of 55 ksi; and Grade 105, which is high-strength alloy, has a yield strength of 105 ksi. F1554 designated bolts can be headed bolts, straight anchor rod bolts, or bent L-anchor bolts.
Its high tensile strength makes B7 one of the strongest materials. A grade of specification A193 (Chromium Molybdenum, it gets its strength from a heat-treating process that involves quenching and tempering the steel at 1150°F. It is specifically designed for industries and applications where high temperatures and pressures are achieved like in pressure vessels and valves in the oil and gas industry. B7 is one of the strongest materials used in the manufacturing of threaded rods.
This is a type of stainless steel that includes at least 18% chromium, 8% nickel, and 0.08% carbon. It is the most common of the 300 series stainless steels. The chromium allows it to resist oxidation and corrosion. The high corrosion-resistant properties make it ideal for the appliance industry in situations where achieving a aesthetically pleasing appearance is essential.
This is a highly corrosion-resistant stainless steel similar to 304SS. It is one of the highest grades of stainless steel. It includes chromium, nickel, and molybdenum that helps it resists chlorides like salt. Therefore, Stainless Steel 316 is mostly used for marine environment applications where salt water is involved.
Material with this grade includes 18% chromium and 8% nickel content, thus its designation. It is not It is not a grade that is typically used to call out fasteners manufactured from 300 series stainless steel that have varying levels of this mixture. Fasteners designated 18-8 are used to prevent rust in applications where moisture is present. Abrafast.com offers a variety of fasteners for just about every building application.
