CS-B Hot Rolled/HRPO/CR/Galvanized/ Galvannealed/Galvalume Sheet

There are advantages to each CS type B format.

• Hot rolled CS-B is an economical option that has a rougher finish and is best for applications that do not require highly precise geometry, weldability, or aesthetics. It’s best for getting tough jobs done without a fuss, like general construction projects.
• HRPO CS-B is similar to hot rolled CS type B, however pickling and oiling significantly reduces the likelihood that the steel will crack.
• Cold rolled CS-B shows a smooth surface with much more consistent thicknesses throughout. It is also capable of achieving tighter tolerances for applications that require greater precision. One downside for cold rolled steel is that you lose some of the formability for this aesthetic appeal.
• Galvanized CS-B improves corrosion resistance and aesthetic appeal.
• Galvannealed CS-B offers superior weldability making it a top choice for fabricated parts, tools, and components for things like bridge construction and automotive manufacturing.
• Galvalume CS-B is most advantageous for outdoor conditions like metal roofing and other building products as it is the most protected in harsh conditions over time.

The main disadvantage for CS-B is that it offers limited formability and should not be used for any applications where deep drawing is needed.

CS-B shows up in general construction, automotive, shipping, and many other industries. Depending on the specific processing and treatments applied, you might be more or less likely to see CS-B. However, this general purpose steel is an option for applications that require moderate bending, strength, and good hardness.

There are a wide range of applications for CS type B. This depends on which processing or treatment CS-B undergoes. You can expect to see it in general construction projects, railroads, HVAC, ductwork, furnace pipes, ship and automotive manufacturing, bridge construction, office furniture, and many others.

CS-B can be machined. Certain machining qualities are enhanced depending on the format.

CS-B can be welded. Hot rolled dry CS-B results in the harshest weld quality. Galvannealed CS type B offers the best weldability. This is mainly due to the presence of oxide impurities on the surface of the steel.

This is a heat treatable low carbon steel.

Hot rolled CS-B is the least processed format available. Hot rolled CS type B will have a much rougher surface with the highest amount to surface impurities, or mill scales, than any of the following formats. This format is ideal for general construction. However, without the pickling and oiling process, it is more susceptible to cracking and is best for applications that do not require a shiny or smooth surface. Applications that might require highly precise geometry or significant welding are not typically recommended for this low carbon flat roll product.

HRPO CS-B improves workability while also reducing the likelihood of cracking. It also demonstrates improved rust resistance. It is one of the most affordable options to extend the life of the steel.

Cold rolled CS-B offers an aesthetically pleasing look, tighter tolerances, clean edges, and even thickness at the expense of formability.

Galvanized CS-B has a shiny surface with mild forming and bending character. It also offers protection from rust.

When compared to the other CS-B product formats, Galvannealed CS-B offers the best weldability. Beyond weldability, it shows significant improvement in workability more generally as the annealing process counteracts some of the downsides of the cold rolled process.

Galvalume CS-B offers the best protection. With the combination of zinc-aluminum-iron-silicon, this format holds up well in outdoor conditions and will outlast other product formats.

ANSWER:

To galvanize or galvanneal CS-B means to expose the bare steel to processes and treatments. Galvanization is a process that involves placing the steel in a hot bath of nearly pure zinc. When the zinc interacts with the oxygen in the air the steel acquires a protective zinc coating. CS-B galvannealed steel (and every other galvannealed grade) has first undergone this process of galvanization.

The main differerence is that galvanized, zinc-coated steel, does not take on subsequent heat treatment. Annealing galvanized steel results in different properties and capabilities. For example, galvanized steel will have protection against corrosion. When you add the annealing process immediately after placing the steel in a zinc bath, the zinc protective layer becomes a zinc-iron alloy-coating with a much less shiny appearance. In addition to aesthetic differences, galvanized and galvannealed CS-B might be chosen for different applications due to differences in mechanical properties. Bins, furnaces, general construction, and dumpsters might be common applications for galvanized CS type B steel, whereas CS type B galvannealed steel might be used for truck bodies, electrical components, tool boxes, or even bridge construction.

ANSWER:

Commercial steel type A and type B are similar. One difference is their chemical composition. Type A has a more narrow permissible carbon content window in its specification. Type B can have either lower or higher carbon levels than type B but is generally a harder and stronger steel. Both steels offer only moderate drawing capability and neither should be selected for applications where drawing or deep drawing is required.

ANSWER:

There are three designations for commercial steel. Type B differs slightly from type A with a greater range (both lower and higher) of allowable carbon content, and CS type C is less common but is slightly stronger and harder than type A and B.
