1045 C45 S45C 1.1191 CK45 Steel Plate
Medium carbon engineering plate that machines soft and hardens on the working face
Specifications
Mild Steel Sheet and Carbon Steel Plate
Low carbon and medium carbon plate for structural fabrication road plates bridges and machined engineering parts
This part of the steel plate range covers plain carbon plate in two families. Mild steel plate and carbon steel plate are the same low carbon product under two names and they are used to give additional strength and support to buildings bridges road repair platforms and general fabrication work. Alongside them sits 1045 C45 S45C 1.1191 CK45 plate which is a medium carbon steel and a general engineering structural steel with good machinability and high tensile properties. Buying the structural plate and the machining blank on one order means the welded frame and the turned shaft arrive on the same shipment instead of from two separate suppliers.

What This Range Is For
Structural Plate and Machining Stock Bought Separately
Fabricators source low carbon plate for the frame and medium carbon stock for shafts and wear faces from different vendors. Mild steel plate and 1045 C45 S45C plate come from one order here so both land together.
Grade Names That Differ by Market
1045 C45 S45C 1.1191 and CK45 describe the same medium carbon steel under American European Japanese and German naming. Quoting against the designation on your drawing removes the substitution argument at goods inward.
Surface Condition Wrong for the Next Operation
Hot rolled black surface suits welded structures while cold drawn bright surface suits machining. Stating the surface on the order stops the shop from cleaning material that should never have arrived that way.
Plate Ordered in Full Sizes for Small Parts
Size is customized so plate can be cut to your list before it ships. That removes the offcut you pay freight on and then store for months.
Who Buys It
Buyers Who Order From This Range
- Steel fabricators cutting structural members gussets and base plates for buildings and bridges
- Civil contractors buying road plates and temporary platform steel for excavation work
- Machine shops taking 1045 C45 S45C blanks for shafts spindles and machine bases
- Equipment builders who want structural plate and machining stock on a single purchase order
- Stockists supplying mild steel plate and carbon steel plate to regional repair workshops
Core Advantages
Why Source This Range From Tianyu Metal
Two Carbon Levels From One Supplier
Low carbon mild steel plate for structures and medium carbon 1045 C45 S45C plate for engineering parts sit in the same range so one enquiry covers both.
Medium Carbon Plate That Machines Predictably
CK45 is a general engineering structural steel with good machinability and high tensile properties which is why it is specified for shafts gears spindles and machine frames.
More Than Plate in the Same Grade
CK45 is normally supplied as plate round bar flat bar square bar hexagonal bar and pipe so a fabricated assembly can stay in one grade across several forms.
Hot Rolled or Cold Drawn Surface
Hot rolled black surface is the normal supply for welded structural work and cold drawn bright surface is available where the blank goes straight onto a machine.
Forged Material for Heavy Sections
Large size material is better provided as forging so a heavy blank does not have to be cut from plate that was never rolled to that thickness.
Application Scenarios
Where This Range Ends Up
Building and Bridge Structural Members
Beams gussets base plates and stiffeners where low carbon mild steel plate provides additional strength and support to the structure.
Road Repair Platforms
Temporary road plates laid over trenches and excavations which is one of the stated uses for mild steel plate.
General Fabrication Work
Brackets skids frames and weldments that are cut drilled and welded without any heat treatment step afterwards.
Machined Engineering Components
Shafts spindles and drive parts cut from 1045 C45 S45C 1.1191 CK45 medium carbon plate where machinability and tensile strength decide the grade.
Jig and Tooling Base Plates
Fixture bases and press tooling backing plates cut from medium carbon plate and finished on a mill bed.
Buying Guide
What To State When You Order
State the grade in the designation your drawing uses such as 1045 C45 S45C 1.1191 or CK45 so the certificate matches your document control
Give thickness width and length for every plate on the cutting list rather than a total weight
Say whether you need hot rolled black surface or cold drawn bright surface because the next operation depends on it
Name the standard you are buying to so the chemistry and mechanical test ranges are fixed before rolling
Confirm whether you want plate or another form since the same medium carbon grade also comes as round bar flat bar square bar hexagonal bar and pipe
Tell us the cut edge finish and the packing for the destination port so bundles arrive fit to lift

Mild Steel Sheet FAQ
Is mild steel plate the same thing as carbon steel plate?
Yes. Mild steel plate and carbon steel plate are listed as the same product made from low carbon mild steel. Both names appear on the order and on the certificate so use whichever wording your drawing carries.
What is 1045 C45 S45C 1.1191 CK45 plate used for?
It is a medium carbon steel and a general engineering structural steel with good machinability and high tensile properties. It is chosen where the part is machined after cutting rather than only welded into a structure.
Can you supply CK45 in shapes other than plate?
CK45 is normally supplied as plate round bar flat bar square bar hexagonal bar and pipe. Tell us the section and the size you need and we will confirm what can be rolled or drawn.
Which surface condition should I order?
Hot rolled black surface is the normal supply for structural work. Cold drawn bright surface is used where the blank goes to a machine with little cleanup. Large size material is better provided as forging.
Do you cut plate to our sizes?
Yes. Size is customized. Send the cutting list with thickness width and length per piece and the plates arrive ready to fit rather than as full sheets.
What documentation comes with the plate?
Ask for the mill test certificate with your order and it is issued against the grade you bought so the material can be traced in your production records.
