Types of 4140 Alloy Steel Flat Bars

Hot Rolled EN19 Flat Bars

Hot rolled EN19 flat bars are suitable for heavy-duty engineering components, machine parts and fabrication where strength and further machining are required.

Bright EN19 Flat Bars

Bright EN19 flat bars are suitable for precision-machined components, offering a smoother surface and closer dimensional tolerances that can help reduce additional finishing work.

Cold Drawn EN19 Flat Bars

Cold drawn EN19 flat bars are used for precision engineering parts requiring consistent dimensions, improved surface finish and reliable machining performance.

Peeled & Turned EN19 Flat Bars

Peeled and turned EN19 flat bars feature a machined outer surface that helps remove surface irregularities, making them suitable for components requiring better surface quality and dimensional consistency.

Black EN19 Flat Bars

Black EN19 flat bars retain their dark mill-scale surface and are suitable for general engineering stock where the material will undergo further machining or processing before final use.
