Materials

Nuts and bolts exhibit low strength. However, mild steel is highly flexible. High ductility is a property that makes the material ideal for machining and welding. No different elements – used as an alloying agent, not other types of steel, which makes nuts and bolts known as low-cost bolts.

Carbon steel nut and bolt grades are divided into three different categories based on the carbon content of mild, medium and high carbon steels. Mild steel hex bolts are the most widely used category of all carbon steel groups. Mild steel threaded bolt alloys typically contain less than 0.25% carbon by weight. Since this type of carbon steel bolt cannot be hardened by heat treatment to promote the formation of martensite, the alloy is cold worked.

Carbon steel is defined as any steel with a carbon content not exceeding 2.1% by weight. Carbon steel bolts become harder and increase in strength after heat treatment as the carbon content increases. However, the ductility of the steel decreases.

Within this specific category of mild steel is another steel called High Strength Low Alloy Steel, or HSLA for short. Although HSLA screws belong to the mild steel category, it can be noted that HSLA screws also contain other elements in their alloys, such as copper, nickel, vanadium and molybdenum.

Regardless of the heat treatment applied to the carbon steel alloy, the higher carbon content in the material reduces the weldability of carbon steel fasteners, while also effectively reducing the melting point of the bolt. Most carbon steel studs are generally softer.

The combination of all elements of the bolt accounts for 10% of the weight of the steel. As the name suggests, HSLA bolts are heat treated for higher strength. These washers remain ductile, making them easy to form and machine, while exhibiting higher corrosion resistance than ordinary mild steel.

They also exhibit low strength. However, mild steel is highly flexible. High ductility is a property that makes the material ideal for machining and welding.

Medium carbon steel bolts, anchor bolts, screws, studs, nuts and self-drilling screws contain between 0.25 – 0.60% carbon and 0.60 – 1.65% manganese by weight. The mechanical properties of these studs are improved by heat treatment.

No different elements – used as an alloying agent, not other types of steel, which makes nuts and bolts known as low-cost bolts. Carbon steel nut and bolt grades are divided into three different categories based on the carbon content of mild, medium and high carbon steels.

High carbon steel bolts have a carbon content between 0.60 – 1.25%. High carbon steel alloys have manganese content in the range of 0.30 – 0.90%. Of all three grades, high carbon steel threaded rod has the highest hardness and toughness while exhibiting the lowest ductility. The high wear resistance comes from the fact that these screws are almost always hardened and tempered.

Nuts are attached to corresponding bolts or rods to secure items. Cap nuts protect the threads of fasteners by preventing them from protruding. The locknut and locknut are locked on the bolt to prevent loosening. Thumb nut and wing nut are manually adjustable. The connecting nut is an extension for connecting two threaded rods.

Carbon steel bolts are one of carbon steel fasteners. There are different types of carbon steel and they all have high hardness. HT PIPE is a leading manufacturer and supplier of carbon steel nuts and bolts and other fasteners.

There are studs, washers, threaded rods, screws, etc. Each type of fastener has its own advantages and application requirements. Carbon steel screws can be used without nuts. It can be driven with a screwdriver.

Carbon steel studs are used to hold two components together in tight spaces. Carbon steel materials have poor ductility but high hardness. This allows carbon steel to be used in applications that require high hardness, such as carbon steel studs in the oil and gas industry and in power transmission lines.

Fasteners vary in size, shape, grade and specification. The most commonly used fasteners are bolts and nuts. Carbon steel washers are also commonly used to tightly mate nuts with bolt heads and mating surfaces.

Incoloy 800-800H-800HT bolts are a nickel-iron-chromium alloy with good strength and resistance to oxidation and carburization under high temperature exposure. These nickel-steel alloys are the same, except the 800H alloy has a higher carbon content, and up to 1.20% aluminum and titanium have been added to the 800HT alloy. General corrosion resistance is considered by many to be very good. Alloys 800H and 800HT exhibit excellent creep and stress rupture under solution annealed conditions.

Incoloy alloys belong to the Inconel family. This means that the alloy can be used at high temperatures. At high temperatures, a problem associated with certain grades of stainless steel is oxidation. The chemical composition of Incoloy 800 fasteners allows them to be used at high temperatures. The higher the carbon content, the more chance they have to withstand high temperatures. Therefore, manufacturers produce derivative alloys of UNS N08800 bolts, called Alloy 800H and Alloy 800HT, which have slightly different chemical compositions.

During natural gas processing, several common contaminants, such as water, carbon dioxide, and hydrogen sulfide, come into contact with equipment components, including alloy 600 studs.
