Hot Rolled Pickled and Oiled HRPO Steel Sheet

Hot rolled pickled & oiled steel sheet advantages workability and corrosion resistance. Because it is heated it can be easily bent and formed. The pickling and oiling process offers improved resistance to corrosion. One disadvantage of HRPO steel sheet is that its workability can come at the expense of mechanical properties. For example, when compared to cold rolled steel HRPO steel sheet will typically achieve lower strengths and be less durable. However, the amount of time it takes to hot roll, pickle, and oil the steel tends to be much shorter.

HRPO is commonly seen across industries. From agriculture to automotive, and energy to general construction HRPO products can be used toward a range of uses. It is often selected for general commercial fabrication projects, including for the transportation, construction, and architectural industries.

Applications for HRPO steel sheet are many! Agricultural tools, automotive components, barrels, structural parts, welded structures, and transmission towers are just some of the possible applications. HRPO is good for unexposed parts and applications since the surface character is not critical and where a little give to the metal is ideal.

HRPO is machinable. It is considered a malleable steel product that can be easily bent, formed, and cut into nearly any shape or configuration necessary. In fact, this is one of the main advantages to HRPO products.

HRPO is easily welded. This is one of the main benefits to the pickling process. Since oxide impurities are generally an obstacle to quality welds, removing them by pickling the steel simplifies the welding process. This is one of the reasons you are likely to see HRPO products used widely in welded components and structures.

HRPO requires high heat in order to be produced. Temperatures must reach at least 1700 degrees Fahrenheit before the steel can be rolled. Heat treatment produces a more malleable steel that can be easily machined.

General purpose A1018 steel is a low carbon steel grade. It shows good weldability, machinability, formability, ductility, and toughness. This HRPO product grade is commonly used in chain pins, machine parts, tools and mold components.

A1011 provides improved mechanical properties as a high strength low alloy sheet. Some advantageous qualities for this HRPO steel grade include improved corrosion resistance, formability, and weldability. General fabrication projects, agricultural tools, automotive components, steel barrels, and structural parts are all common uses for A1011.

HRPO “CS”, or commercial steel, is intended for mild forming and bending. Often, this product grade is used in unexposed applications where smooth surface finish is not critical.

ANSWER:

Hot rolled pickled & oiled steel sheet improves workability, including the ability to be bent and formed, as well as improves corrosion resistance and surface finishing character.

ANSWER:

Hot rolled steel first requires the steel to be at 1700°F. At this high temperature, the steel will be malleable enough to be formed flat. It gets passed through rollers. Because cooling steel down from 1700°F doesn’t happen instantaneously, it can lead to organic surface impurities and uneven thicknesses. This is just one reason hot rolled steel is often used for applications where surface finish will not impact quality.

ANSWER:

Temperature isn’t the only difference between cold rolled and hot rolled steel, but it is an important one. Hot rolled steel requires the steel to be at 1700°F. At this high temperature, the steel will be malleable enough to be formed flat.

Cold rolling steel does not require the steel to be hot. At room temperature, it’s passed through high pressure rollers. When compared to hot rolled steel, cold rolling offers more control and consistency throughout the process and results in a more refined surface finishing and better durability. It also achieves higher strengths than hot rolled steel.

Cost can be a difference between these two products as well. Cold rolling tends to require more extensive processing and special equipment that’s usually reflected in the cost.

ANSWER:

Pickling is the process through which steel is exposed to a hydrochloric bath to remove oxide impurities. Descaling the steel benefits bending, forming, stamping, and painting. Then the steel is oiled which enhances resistance to corrosion. Together, HRPO amounts to production savings and an improved overall steel quality for any finished part.

ANSWER:

Oiling indicates that a thin layer of oil has been applied to the steel. Oiling steel improves corrosion resistance.

ANSWER:

Hot rolled coil prices are influenced by an extensive array of factors, including: raw material costs, mills, federal lending rates, globalization and geopolitical issues, any unexpected natural disasters or events that might influence production or distribution, basic supply and demand economics, inventories and export policies, energy costs and more.
