Alloy Steel Bar – EN 19
EN19 is a high quality alloy steel with tensile strength. With a combination of good ductility and shock resistance, EN19 is suitable for applications with very high loading such asengine gear boxes. Popular in the automotive sector it is possible to machine the material extremely accurately, in recent years EN19 has become an established material in the Oil Gas sector.
The material lends itself well to any application where strength is a primary consideration.

Alloy Steel Bar – EN 24
EN24 is a very high strength steel alloy which is supplied hardened and tempered. The grade is a nickel chromium molybdenum combination - this offers high tensile steel strength, with good ductility and wear resistance characteristics. With relatively good impact properties at low temperatures, EN24 is also suitable for a variety of elevated temperature applications.
Applications • High strength shafts • Punches & dies• Drill bushings • Retaining rings • GearsChemical Composition(weight %) STEEL CARBON C % SILICON Si% MANGANESE Mn% CHROMIUM Cr% MOLYBDENUM Mo% SULPHUR S% PHOSPHORUS P% NICKEL Ni% EN 24 0.36-0.44 0.10-0.35 0.45-0.70 1.00-1.40 0.20-0.35 0.040 Max 0.035 Max 1.30-1.70
