S275 S275JO S275JR S275J2 Steel


Xinhairunda Steel are suppliers of S275 steel plate, round bar and flat bar. S275 is an unalloyed low carbon mild steel grade supplied as hot rolled. As a low carbon steel specifications S275 provides low strength with good machinability and is suitable for welding. S275 was first introduced in 1990 by the European Committiee for Iron and Steel Standardisation, The steel was first specified in the EN10025 standard and later published in the UK by the British Standards Institure (BSI) as BS EN 10025 S275 & S275JR. The new grade superceded the previous British Standard BS 4360 43A which has now been offically withdrawn. The average minimum yield for this material is 275 N/mm², hence the name S275.

Heat Treatment

S275 is not ideally suited to hardening, though it can be subjected to limited heat treatment process such as case hardening. When hardening S275 heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Please consult your heat treatment provider for full guidance on heat treatment of S275 carbon steel.


S275 steel is commonly available with a 3.1b mill certificate, cast and analysis certificate or a certificate of conformity, please request when placing any orders.
