PDF datasheet

S355, S355J2, S355J2+N steel stockholders and suppliers, delivering to the whole of the UK. West Yorkshire Steel are suppliers of S355 grades in steel plate, round bar and flat bar. As an unalloyed low carbon mild steel grade S355 is supplied in the hot rolled condition. The S355 steel specifications are high yield non alloy steels. First specified in the European EN10025 standard and later published by the British Standards Institure (BSI) as BS EN 10025 S355, S355J2 and S355J2+N. These standards superceded the BS4360 grades. The average minimum yield for this material is 355 N/mm², hence the name S355.

Applications

S355 is a low carbon steel grade often used for application which require better mechanical properties than that of S275 grade. Commonly supplied in the as rolled condition it is used widely in the construction, manufacturing and offshore industries.


Steel Profiles

S355 steel profiles are available as multiple or one off pieces. Flame cut steel plates can be supplied surface ground and edge machined to your required sizes.

After being flamecut pieces can be ground to clean up or cut plates can be Lumsden ground to size on thickness to an tolerance of +/-0.25mm. A tighter tolerance may be possible, please provide your required tolerances when enquiring with our sales team.


Typical Mechanical Properties*

As a hot rolled non alloy high yield steel the main characterisitics of S355 are its mechanical properties, such as the tensile strength and yield strength.

Heat Treatment

S355 is not ideally suited to hardening, though it can be subjected to limited heat treatment process such as case hardening. If hardening S355 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 carbon steel grades.


Certification

S355 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. 


Quality Assured Supply

S355 steel is supplied in accordance with our ISO 9001 : 2008 registration.
