Iron

GRAY CAST IRON (1.7 ... 4.4% C) ... slow cooling (least expensive)
WHITE CAST IRON (1.7 ... 4.4% C) ... rapid cooling (produces Martensite)
MALLEABLE CAST IRON (1.7 ... 4.4% C) ... fully annealed white cast iron
LOW CARBON PLAIN STEEL (0.1 ... 0.3% C)

S – denotes the fact that it is Structural Steel
235 – related to the minimum yield strength of the steel (tested at a thickness of 16mm)
JR / J0 / J2 / K2 – material toughness in relation to the Charpy impact or ‘V’notch test methodology
- JR ... (27J Charpy test at Room temp) standard stock - lowest price
- J0 ... (27J Charpy test at 0°C)
- J2 ... (27J Charpy test at -20°C)
- K2 ... Hardened (40J Charpy test)
W – Weathering Steel (Atmospheric Corrosion Resistant)
Z – Structural steel with improved strength perpendicular to the surface
C – Cold-formed
