BS EN 10204:2004 is British Standard that related to different types of inspection documents for steel metal products. There are 4 types for EN 102024, 2.1, 2.2, 3.1 and 3.2, the later two types are the mostly used in steel pipe and plates products, so here we will mainly introduce the major differences between two types.

Mild steel is a type of low carbon steel. Carbon steels are metals that contain a small percentage of carbon (max 2.1%) which enhances the properties of pure iron. The carbon content varies depending on the requirements for the steel. Low carbon steels contain carbon in the range of 0.05 to 0.25 percent. There are different grades of mild steel.

Tempering - AISI 1018 mild/low carbon steel is tempered at 150°C – 200°C to improve case toughness. This process has little or no effect on hardness. Grinding cracks are reduced when AISI 1018 mild/low carbon steel is tempered. Annealing - The AISI 1018 mild/low carbon steel is heated at 870°C – 910°C and allowed to cool in a furnace.
