Everything You Need To Know To Find The Best hot rolled steel products

Looking for steel products and not exactly sure what type you need? Turn to the experts at Metal Supermarkets to guide you in the right direction.

You can find more information on our web, so please take a look.

When deciding between Hot Rolled and Cold Rolled steel, all you need to know is what the material will be used for, how it will be used, and the size requirements. The Metal Supermarkets team will use these details to determine which type of steel will be best for your project.

Dwayne Swenson, owner of Metal Supermarkets Seattle (Kent) and Tacoma in Washington and Portland, Oregon, talks about the popularity of Hot Rolled and Cold Finished steel products, 'Hot Rolled steel is the most popular type of steel we offer. Construction grade A36 Hot Rolled (mild steel) bar is the bread-and-butter steel product for a lot of industries because it is more ductile (pliable) and generally less expensive than Cold Finished drawn products.'

Hot Rolled Steel vs Cold Rolled Steel

The first thing to remember is that the terms Hot Rolled and Cold Rolled do not refer to any grades or strengths, but merely the process used to create the bar product at the mill.

Hot Rolled Steel is softer and more pliable than Cold Rolled Steel. Hot Rolled Steel has a light- grey, rough finish and rounded edges (in Flat and Square Bars), and Hot Rolled products are typically oversized.

Hot Rolled steel bars are used in the welding and construction trades where the items being constructed do not require super precise shapes and tight tolerances.

Cold Rolled Steel typically has a smooth, somewhat shiny finish with square edges (in Flat and Square Bars), and the sizes are more precise.

Cold Finished steel bars are preferred in the machining world where the quality of the steel is an important factor of the quality of the final product, and the appearance of the steel is also an important factor.

Grades and Uses

What does grades of steel mean?

Steel is essentially an alloy of iron and carbon, and sometimes other elements such as manganese. However, the amounts and proportions of these elements in a particular batch of steel varies. The way steel is manufactured also plays an important role in determining its end application. Thus, simply put, the grade of steel is a way to categorize steel based on the different factors that influences its properties.

What is the need for having multiple steel grades?

We know how far-reaching steel's applications are ' from smartphones to bridges, steel is used in almost everything we use every day. This necessitates the production of specialized steel that best suits particular applications. For example, steel Grade is suitable for high-heat applications such as gears or moving parts while grade 500's toughness and load bearing capacities are used in heavy-duty mining equipment.

Steel grade is a system that helps distinguish steel in terms of its physical and chemical properties. Various stakeholders in the steel industry, for example, steel manufacturers, dealers and engineers, use the steel grading system to standardize the quality of steel to be used. These standards provide a common language to communicate the properties of steel with great specificity, and guide product manufacturers toward proper processing and application procedures.

What is hot rolled steel?

In hot rolling, steel is milled at a temperature higher than steel's recrystallization temperature, which is usually more than degrees Fahrenheit. This ensures that the steel can be shaped and formed easily and can be manufactured in large sizes. However, it is important to note that 'hot-rolling' is not a grade of steel; hot rolling can be used to make steel of various grades.

What are some of the most-used hot-rolled steel grades?

Hot rolled steel sheets and coils find a wide range of applications in structural and general engineering, welded pipes and tubes, automobile manufacturing and LPG cylinders to name a few. The grades can vary accordingly. At JSW Steel's manufacturing units in Dolvi, Maharashtra, and Vijayanagar, Karnataka, hot rolled steel is produced in plain structural carbon grade, medium carbon grade, high tensile grades of Fe510 and Fe590, two grades of API PSL, low carbon EDD IF steel, and TRIP steel.
