C20 Bright Bar

C20 Bright Bar

● Grade introduction 

Low carbon, unalloyed gentle steel grade C-20 is presented as hot-rolled or splendid drawn finish bars. It is fitting for welding since it is a low-carbon steel grade that offers low strength and great machinability.

● Grade Application 

every now and again utilized overall designing For utilizes including bolts, shafts, spacers, centers, baseplates, sections, fittings, and dances, C-20 is suitable.

● C20 Bright Bar Hardness: 

Hardness is the ability to oppose surface scraped spots and space (confined plastic disfigurement). Because of the way that it could suggest protection from scraping, scraped spots, space, molding, or even restricted plastic mishappening, hardness is perhaps the element of a material that is least obviously characterized. According to a design point of view, hardness is significant on the grounds that protection from wear brought about by contact or disintegration brought about by steam, oil, and water frequently ascends with hardness.

One of the space hardness tests made for hardness testing is the Brinell test. In Brinell tests, a hard, circular indenter is crashed into the outer layer of the metal under test at a foreordained burden. In many tests, an indenter with a 10 mm (0.39 in) width solidified steel ball and a 3,000 kgf force is utilized (29.42 kN; 6,614 lbf)force. The heap is saved consistently for a foreordained timeframe (somewhere in the range of 10 and 30 s). A more modest power is applied to milder materials, while a tungsten carbide ball is used instead of the steel ball for more earnest materials.

● C20 Bright Bar Heat treatment: 

Because of factors including the shape and size of every part, heat treatment temperatures, including the pace of warming, cooling, and drenching lengths, will shift while solidifying C-20. The sort of heater, the extinguishing specialist, and the workpiece transport offices are different elements to consider during the intensity therapy process.

● C20 Bright Bar Hardening: 

C-20, a low-carbon steel, isn’t the ideal material for heat treatment (C-20 or EN9 might be a more qualified choice). Intensity to a scope of 880 to 910 °C in the event that solidifying is essential. Slake the rod with water.

● C20 Bright Bar Tensile strength 

High-carbon steel has an extreme rigidity of 685 MPa. On the designing pressure strain bend, a definitive rigidity is at its most noteworthy. This is comparable to the greatest pressure that a construction in strain can endure.

● C20 Bright Bar Wield strength 

High-carbon steel has a yield strength of 525 MPa.

The yield point on a pressure strain bend is where versatile movement closures and plastic conduct begins. The material property known as yield strength or yield pressure is depicted as the strain at which a material begins to plastically twist. The start of nonlinear (versatile + plastic) distortion, in any case, happens at the yield point. The material will flexibly distort before the yield point and resume its unique shape once the applied burden is wiped out. Some pieces of the misshapen will become super durable and irreversible once the yield edge is passed. The yield point peculiarities are a way of behaving that a few preparations and different materials show. Low-strength aluminum has a yield strength of 35 MPa, while high-strength steel has a yield strength in excess of 1400 MPa.

● Customer value 

  • Surface finishing—without centerless grinding, belt polishing to Ra = 0.2 um (12 RMS), and grit polishing to 180 grit.
  • 100% crack-free bright bars—A magnetic particle inspection (MPI) test is conducted on every bright bar to verify that there is no crack and the bright bar is made crack-free. 
  • Premium quality testing- A high degree of safety is assured by using high ductility bolstering steel that is not brittle. In more than 100 steel grades, the products are exported to more than 50 countries.
