Due to the fact that wire ropes are produced in different variations and depending on different needs, each of them has unique applications in different industries. Therefore, these steel ropes must be ready to be used in any weather conditions and different chemical conditions. Therefore, the towing wires are made resistant to destructive factors such as water and humidity, chemicals, ultraviolet radiation of the sun, etc. There are different ways to perform this retrofitting, such as galvanizing in the form of hot galvanizing and cold galvanizing, or producing steel towing wires, etc. One of the cheapest and most productive methods of retrofitting is coating the towing wire or rope. Steel is made of polymer materials.

TYPES OF CHAIN GRADES
Industrial chains consist of linked segments of durable metal, such as stainless steel, galvanized steel, and brass. They are available in a wide range of sizes and strengths to lift and transport materials across a diverse set of applications.

The tensile strength of the base material—i.e., the ultimate breaking strength—determines the rating and grade given to the particular chain. The greater the breaking strength, the higher the grade, and vice versa. The grade indicated for a chain helps industry professionals identify the types of applications for which it is appropriate. For example, the strength of galvanized chains relies on the amount of carbon present in the metal as grade 30 chain has less carbon, it is weaker than grade 40 chain and suitable for service duty applications rather than heavy-duty applications.

At Armstrong / Alar Chain Corporation, we pride ourselves on our extensive knowledge and experience with metal chains

Dry G80 chain, which has a high percentage of 97% iron in its alloy composition, is one of the most widely used grades of steel chain. This grade is produced from steel chain with medium carbon percentage, but its mechanical characteristics have been improved by performing a precise heat treatment. This heat hardening process causes higher continuity and, as a result, higher abrasion and tensile resistance in the chain steel crystals. The most commonly used size of this grade of chains is 6 mm to 24 mm, which is used in the manufacture of chain slings and also lifting connections. G80 grade chain must be produced and manufactured according to DIN 818 standard. G80 grade chain is available in polished type, black steel color, hot galvanized, cold galvanized, PVC coated, or plastic, etc. The lowest safety factor f:s of G80 chain should be 4 times its SWL and its Proof Test is 2.5 times SWL.
G80 grade chains are produced through forging operations and are made by cutting steel wires and then welding the points of connection of the grains of this chain. The contro

Steel Wire Rope

The steel rope, which we know as tow wire in Iran, is a steel rope, which is made of several steel strands woven together, which is also made of several wires. Steel is made around a central wire.
Wires are classified into two general categories: "steel core wire" and "hemp core wire". Each of these two types has its own uses according to the way of use and the place of use.

What is hemp cord towing?
In some steel ropes, according to the environmental conditions and technical conditions that are considered in moving the load, or the conditions of the machine in which the towing wire is used, we are required to use this type of towing wire.
Hemp ropes are divided into two categories: natural fibers and synthetic fibers.
NFC: Natural Fiber Core tow rope with natural hemp: this type of tow rope has a hemp core made of natural fibers of the hemp plant. Among the features of this type of fiber is the ability to absorb grease in the core of the towing wire, which causes the release of the grease stored in the hemp under high pressures and lubricates and reduces the abrasion of the steel wires to each other.
SFC: Synthetic Fiber Core: This type of tow wire has a core made of polymer fibers. In fact, the steel rope woven in its core has a rope woven with polymer fibers called pol

Carbon steel chain is actually one of the steel grades used in lifting bar. Carbon steel chain is produced with a medium percentage of carbon and the thermal process of hardening is used in order to make the steel crystals uniform, and during the cooling and heating process in several stages, the two mechanical factors of tensile and surface hardness are increased in it.
The Carbon steel chain is known as G80 grade, which is mainly used in carrying cargo with roof racks or as a chain sling. Various sizes of dry chains are used in bar lifting, which ranges from 6 mm to 16 mm. The most widely used sizes of steel chains are 8 and 10 mm sizes, which are used on overhead chain cranes.

G80 carbon steel chain

The dry G80 chain is one of the popular steel grades that is produced with a medium carbon percentage, but with the use of a precise heat treatment, its mechanical characteristics have been increased. In the heat treatment process, the internal steel crystals of the G80 chain are homogenized, which have a higher continuity and, as a result, have a higher wear and tensile resistance in lifting loads. Production sizes are produced from G80 steel chains, which are large in size from 6 mm to 24 mm in lifting connections and in the production of chain slings as well as lifting using cranes.
G80 grade chain has a hardness of 350 in the Brinell HB unit and a tensile strength of about 80,000 pounds per inch or 550 MPa.
