Where is the square bright bar majorly used?
Square bright bars are produced from hot-rolled bars through the processes of cold drawing, peeling, centerless grinding, turning, and shaving. Due to its strong section and robust structure square bright bar is used in transport, both commercial and residential construction, mining applications, and general manufacturing. Along with the square bright bar, there are various other shaped bright bars such as triangle bright bars, hex bright bars, flat bright bars, and oval bright bars. Generally, a bright bar is a carbon steel alloy that is further improved by peeling, grinding, or drawing over the hot rolled finish. Square bright bars are usually available in sizes ranging from 8mm to 63mm.
Types of square bright bars:
- Sharp edge square bright bar
- Natural radius square bright bar
- Round corner square bright bar
- All corner chamfer square bright bar
- Grooved square bright bar
- Key steel square bright bar
Grades of Square Bright Bars:
- Mild steel: It is one of the most essential materials for making square bright bars. The grades of mild steel include SAE1010, SAE1018, SAE1020, SAE1025.
- Semi-free cutting steel: It is a type of steel that can be easily worked upon during mechanical operations. It has more sulphur content in it than carbon content. The grades of semi-free cutting steel include EN-1A, EN-8M, SAE1144, SAE1215. EN-1A square bright bar is one of the most widely used grades in the market.
- Leaded free cutting: It includes EN-1A (Pb), 12L14. These are high sulphur grades used for manufacturing components like Nuts, bolts, studs, brake pistons, hydraulic fittings where greater polishing is required to have a complex structure.
- Carbon steel: It is an alloy of iron and carbon. It is a common type of steel having good carbon content, low melting point, and high durability. The grades of carbon steel include EN8, EN8D, EN9, SAE1035, SAE1045, CK45, 45C8, etc.
- Spring steel: It is generally low-alloy manganese, medium, or high carbon steel with very high yield strength. It is mostly used in the production of swords, springs, saw blades, and many more. The grades of spring steel include SUP7N, SUP7NV, SUP9, SUP12, etc.
- Alloy steel: It is a type of steel in which several alloying elements such as nickel, chromium, silicon, molybdenum, vanadium, and boron are added to increase the strength, hardness, toughness, and wear resistance of the steel. Various grades of alloy steel include 16MnCr5, EN19, SCM415, EN24, SCM440, etc.
Cold finished square bright bars possess upgraded mechanical properties, better surface integrity, dimensional accuracy, and higher machinability. The advantages provided by these qualities of square bright bars are listed below:
- Cold drawing of the shaped bright bar increases the yield, hardness, tensile strength which further provide fatigue strength and better service performance for a longer period.
- The hardness of bright bars enables it to better resist handling damages.
- A polished bright bar offers more accurate cross-section geometries and bar-end conditions which can reduce scrap and yield loss during manufacture.
- Properly rolled, annealed, and grinded bright bar provide a defect-free surface and prevent reduction of carbon content. Hence, the square bright bars can be easily handled manually.
- The clean surface, reduced ductility, and improved dimensional precision of a well-processed square bright bar increases work-holding security and improve machined surface finish.
- Moreover, a high-quality square bright bar provides better wear and corrosion resistance.
Uses of square bright bar:
- Automobile industry: Square bright bar is mostly used in the engine components of the automobile industrial sector. The elements used in the automobile industry such as nuts, bolts, and shafts are made of special grades of square bright bars.
- Railways: In the railway sector square bright bars are specially required for the manufacture of engines and coaches.
