Oxygen-assisted thermal cutting can leave a dark oxide edge; subsequent treatment depends on use. Confirm drawing feasibility, production technology and finishing with Craftarea before ordering. “Iron cutting” often means steel cutting in everyday speech, but a technical drawing needs an exact grade. Carbon-steel sheet is used for brackets, lettering, panels and structural parts. This guide covers contour complexity, edge changes in oxygen-assisted cutting and corrosion protection. Scope, particular equipment and workable thickness require technical confirmation before an order.

Carbon steel and stainless steel have different properties. A dark scale layer can remain on sheet after rolling. For damp or outdoor applications, plan corrosion protection and coating before production. - Iron / iron cutting — everyday term - Steel — general technical term - Carbon steel / mild steel — the precise material name - Stainless / inox / nerzhaveika — a different, chromium-bearing metal ## What determines feasible carbon-steel thickness? A thin decorative part and a thick bracket need different cutting parameters and checks. Alongside grade, relevant factors include power, assist gas, holes, narrow features and edge requirements. Provide the required thickness and drawing; agree workable thickness, method, accuracy and quantity before ordering. ## Why does the cut edge go dark — the physics of oxygen-assisted cutting In oxygen-assisted thermal cutting, heated steel reacts with oxygen and may leave an oxide layer along the edge. Colour and layer thickness depend on process conditions. Subsequent welding, coating and visible edges can require different preparation. Specify the final edge condition and agree any cleaning operation separately. ## Where are cut carbon-steel parts used? Carbon steel is used for brackets, nameplates, frames, decorative panels and partitions. Strength is not determined by material name alone: dimensions, thickness, shape, loading and fixing matter. State any protective coating needed for exterior use. Confirm cutting, bending, welding and painting separately in the scope. ## When should another cutting technology be considered? Thick plate, straight cuts and fine ornament have different needs. Compare laser, plasma, waterjet and mechanical cutting against dimensions, accuracy, edge requirements and subsequent work. Confirm availability of the selected method, operator and production stages before accepting a quote. ## Specification for a carbon-steel part | Requirement | What to describe | What to agree | | --- | --- | --- | | Thin decor | Dimensions, contour and narrow features | Distortion and visible edges | | Bracket | Holes, loads and mating dimensions | Tolerance and finishing | | Thick plate | Grade, thickness and contour | Technical feasibility of the method | | Exterior part | Environment and fixing | Cleaning and protective coating | | Batch | Quantity for each drawing | Sample and acceptance criteria | ## Frequently Asked Questions Are carbon steel, iron and mild steel the same thing? These terms often describe the same steel part in everyday speech. A technical order still needs an exact grade; distinguish carbon steel from stainless steel. What's the maximum thickness you can laser-cut in carbon steel? Send the required thickness with grade, drawing and edge requirements. Capacity depends on the selected equipment and process and needs confirmation in advance. Why does the cut edge come out dark or discolored? Oxygen-assisted cutting can form iron oxide at the edge. If the part will be welded, coated or displayed, agree the preparation and required final condition beforehand. What hole diameter can you cut in carbon steel? The manufacturable minimum hole diameter depends on the metal grade, thickness, geometry and particular equipment. Specify the required size in the drawing; the team confirms feasibility after reviewing the file. Does a cut part need any further processing? Finishing depends on the application. Specify deburring, visible-edge quality, welding surfaces and corrosion protection separately in the brief. What file do I need to prepare for carbon steel cutting? A vector DXF or DWG file with closed contours, drawn at real size; AI and vector PDF are also useful. The file-preparation page covers additional drawing checks. How much does carbon steel cutting cost? A quote needs grade, thickness, complete contour, holes and quantity. Check material, file preparation, edge finishing and delivery separately in the quote. Can you cut plate thicker than 10mm? Plate thicker than 10mm needs assessment of the specific technology. Send the drawing and requirements; confirm feasibility, method, operator and edge finishing before ordering. ## Related Services [Metal cutting — main hub](https://www.craftarea.ge/en/metalze-chra)[Metal thickness cutting guide](https://www.craftarea.ge/en/metalze-chra/metalis-chris-sisqe)[Stainless steel (inox) cutting](https://www.craftarea.ge/en/metalze-chra/inoksis-chra)[Metal cutting price — how it's calculated](https://www.craftarea.ge/en/metalze-chra/metalze-chris-fasi)[Laser cutting on metal — general service](https://www.craftarea.ge/en/lazer/lazeruli-chra-metalze) ## Ready to order?
