Hot rolled steel is used in situations where precise shapes and tolerances are not required. Cold Rolled Steel. Cold rolled steel is essentially hot rolled steel that has had further processing.

HOT ROLLED PICKLE AND OILED (HRPO) PRODUCTS

Hot Rolled Pickled and oiled product is steel that has been descaled, removing the iron oxide scale layer using hydrochloric acid. The material may also be supplied in tempered condition (skin-passed using temper rolls with specific surface roughness) to improve the shape flatness and to apply surface roughness on the strip to Hot Rolled Carbon Steel Coil / High Density Hot Rolled Hot Rolled Steel Sheet.

The process of creating hot rolled P&O begins with basic hot rolled steel. To learn about the process of how hot rolled steel is made visit our hot rolled steel products page or

Hot Rolled Pickled & Oiled (HRPO) Steel Sheet & Coil

Extend longevity in corrosive environments with hot rolled pickled and oiled (HRPO) steel sheet and coil products from Alliance Steel. Hot rolled pickled and oiled sheet and coil have been descaled of an oxide film and oiled to help combat corrosion during storage and when in use.. Hot rolled steel products will scale when in contact with oxygen and water vapor after the forming process. Hot Rolled Steel Round Tube P&O (Pickled & Oiled) - Hot Our Hot Rolled Tube is all Pickled & Oiled (P&O). Pickling & Oiling is a process by which oxides and/or mill scaling is removed from the surface of the material by immersing the steel in a bath of diluted sulphuric or hydrochloric acid. Hot Rolled Steel Sheet, Pickled and Oiled Steel Products Hot Rolled Pickled and Oiled hot rolled coil or sheet steel that has been descaled of oxide film by either a chemical method, mechanical method, or a combination of both and oiled to help retard corrosion during storage and after descaling. "HRPO" is available in various gauges, widths, and cut lengths or coil. Hot Rolled Pickled & Oiled ASTM A-1011

Mill Forms - assda.asn.au

This finish may be achieved by supplying a surface in the as-pickled condition, or by doing some of the cold rolling on roughened rolls. The finish may be skin passed. 2D surface roughness is in the 0.5 to three micrometre range, although when roughened surface rolls are used the wavelength of the surface undulations is too long to be measured Pickled & Oiled Steel Plate & Coil Hansen Steel ECW Hansen Steel provides numerous metal fabrication services in-house including plasma and laser cutting, robotic welding, and metal stamping. Hot rolled pickled and oiled steel is ideal for laser cutting applications due to its easy cutting material. Advantages:smooth finish, great for laser cutting and metal punching; Thickness:14 ga. 3/4 Pickling Behaviour of 2205 Duplex Stainless Steel Hot Abstract. Pickling behaviour of the oxide layer on hot-rolled 2205 duplex stainless steel (DSS) was studied in H 2 SO 4 solutions with electrolytic workstation. The pickling rate at 75°C increases slightly with the H 2 SO 4 concentration from 100 to 250 g L 1 but increases markedly as the concentration is higher than 250 g L 1.The solution temperature greatly accelerates the pickling rate.

Pickling of Hot Rolled Strip of Carbon Steel in Pickling

Apr 23, 2013 · Fig 3 Surfaces of hot rolled steel strip and pickled steel strip. Pickling solutions. For carbon (C) steel, sulphuric (H2SO4) acid is used in most batch pickling operations, whereas hydrochloric (HCl) acid has become the pickling agent of choice, as of 1994, for continuous operations with hot rolled strip. Products Archive - Steel Technologies LLCCold Rolled Strip. Cold-rolled strip is scale-free hot rolled steel that has been further processed through cold rolling, annealing, slitting, and edging to achieve extremely precise dimensional tolerances and customized properties including microstructure, chemistry, surface finish, and tempers. From low carbon 1001 through 1095 and alloy steels. Steel - Surface treating BritannicaSteel - Steel - Surface treating:The surface treatment of steel also begins during hot-rolling, because reheating conditions, in-line scale removal, rolling temperature, and cooling rate all determine the type and thickness of scale formed on the product, and this affects atmospheric corrosion, paintability, and subsequent scale-removal operations.

Steel Processing:Pickling and Oiling :Wilton Steel

Steel pickling and oiling is a metal surface treatment finishing process used to remove surface impurities such as rust and carbon scale from hot rolled carbon steel. The steel is submersed in a bath of pickle liquor, a solution of Hydrogen Chloride acid, to remove the impurities from the surface of the steel. Surface Finish:1U 1C 1E 1D 1X 1G 2A 2H 2C 2D 2E 2B 2G 2P May be followed by pickling. Surface roughness is depending on the mechanical descaling method and may differ if the surface is e.g. shot blasted or brushed. 2D:Cold rolled, heat treated, pickled:Smooth:Finish for good ductility, but not as smooth as 2B or 2R. 2B:Cold rolled, heat treated, pickled, skin passed:Smoother than 2D Hot Rolled Steel Sheet P&O (Pickled & Oiled) - Hot Rolled Hot Rolled Steel Sheet P&O (Pickled & Oiled) ***PLEASE CALL FOR PRICING AND SHEET AVAILABILITY*** Product Description:ASTM A-36 Mild Steel is the most commonly available and one of the most economical metals on the market today. Our Hot Rolled Sheets are all Pickled & Oiled (P&O).
