What Are The Different HR Sheet Grades And Their Uses

 


HR steel is more widely used than cold-rolled sheets due to its strength and vitality. Mostly, it is used for compressing, framing, and other important strategies like moving, rolling, and extrusion. The HR steel may not have the best quality but when it starts to cool down, the material can be one of the ideal ones for creating products.

Several grades of Hot-rolled steel are used in specific applications. However, each grade needs to meet its specific standard for being used in the processing of the product. The flexibility of the product makes it mold into a variety of shapes and sizes.  In total there are 8 types of steel grades. Let's take a look at them. 

Learn about the different HR sheet grades and their applications

The hot-rolled steel is a type of carbon steel, that is heated at or above 1,7000° F. This is the recrystallization point. Following this, the material is then flattened as per the required size and shape and modified into different forms. The products formed can be of different types: low-carbon (up to 0.3% carbon), medium-carbon (0.3–0.6% carbon), or high-carbon (more than 0.6% carbon).

The HR sheet grade has better mechanical properties which make it a better material for many applications. These properties also make it the first choice for being used in applications like railroad tracks, sheet metal, and construction.

Let's take a look at the different HR grades that are categorized by steel dealers in India.

1.      A36: This steel grade is widely used to make different products due to its high weldability and machine-washing ability. Besides this, it also has excellent mechanical properties.  Some of the applications of A36 include:

·         Frames of trucks

·         Agricultural equipment

·         Shelving

·         Structural support like walkways, ramps, and guard rails

·         Trailers

·         General Fabrication

2.      C1010 and C1018: These are widely in demand among steel dealers in India due to their machinability. Further, they are more flexible, compared to high-carbon steels. The only difference between C1010 and C1018 is that C1010 has 0.08% to 0.13% carbon content by weight, while C1018 has between 0.14% to 0.20% carbon content by weight. The different appliances of these steel grades include:

·         Gears

·         Oil tool slips

·         Pins

·         Chain pins

·         Liners

·         Studs

·         Anchor pins

3.      A1011: This is used by pre-engineered building manufacturers in India for the manufacturing of products like automobile bodies, metal fabrication, and sheet metal structural applications.

The different applications of this HR sheet grade include:

·         Building, roofing & construction

·         Automotive & Transportation

·         Shipping containers

·         Appliances

·         Heavy equipment

4.      A500: This steel grade is a low-carbon alloy and is used only for tubing.

5.      C1045: This HR sheet grade is AISI-designated. Surprisingly, even as a medium-carbon steel, this can provide great strength and durability.

6.      C1026: This Steel grade, like the C1045, is also AISI-designated. It even has similar mechanical and chemical properties to the A36 grade but with reduced carbon content. Such features make it perfect for being used by pre-engineered building manufacturers in India for manufacturing furniture, automotive components, and much more. 

7.      C1141: This is a medium-carbon steel grade. It contains manganese and sulphur which makes it machineable.

It is important to choose the right steel grade depending on the purpose of the steel. By using the right material, the manufactured product will be much more durable and will last longer.

Why Do Pre-Engineered Building Manufacturers In India Prefer TMT Bars Over TOR Bars?

Image
  For most construction purposes, steel has turned out to be an ideal material. A unique factor about this material is that it reinforces the concrete which makes the structure much more strong, and protects it from easy wear or rust caused due to a natural calamity. This is also the reason why pre-engineered manufacturers in India choose TMT bars over any other bar. The different steel bars have different categories. Further, they are also dependent on geographical and environmental factors. Previously, the TOR bars were in high demand in the 1990s, but after the inclusion of the TMT steel bars, its properties captured the market. Reasons why pre-engineered building manufacturers in India choose TMT bars There are a number of reasons why TMT bars are in so much demand among TMT bar suppliers in Chennai . Let's take a look at them. 1.       Corrosion resistant The biggest reason for a structural failure can be corrosion. The high concentration of...
