EN8 Steel
EN8 Steel is a medium carbon steel grade conforming to BS 970 EN8, equivalent to AISI 1045 and DIN C45 (1.0503). It contains approximately 0.36–0.44% carbon, which provides a good balance of strength, toughness, and wear resistance. In the normalized condition, EN8 offers a tensile strength of 550–700 MPa and hardness of around 150–200 BHN, making it suitable for components requiring moderate strength and durability. It has good machinability and can be heat treated through hardening and tempering to improve mechanical properties. EN8 steel is widely used in the manufacturing of shafts, gears, studs, bolts, axles, and general engineering components across automotive and industrial machinery sectors.
EN8D Steel
EN8D Steel is a medium carbon steel grade conforming to BS 970 EN8D, equivalent to AISI 1045 and DIN C45 (1.0503). It contains approximately 0.40–0.45% carbon with controlled sulphur content for improved machinability compared to standard EN8. EN8D offers good strength, toughness, and wear resistance, making it suitable for applications requiring higher mechanical performance. In the normalized condition, it typically provides a tensile strength of 600–800 MPa and good impact resistance. The material can be heat treated through hardening and tempering to achieve enhanced hardness and durability. EN8D steel is widely used for manufacturing shafts, gears, studs, bolts, crankshafts, axles, and various automotive and general engineering components.
EN353 Steel
EN353 Steel is a low carbon alloy case hardening steel grade conforming to BS 970 EN353, widely used for components requiring high surface hardness and a tough core. It contains low carbon with alloying elements such as chromium and nickel, which improve hardenability and wear resistance. EN353 is specially suitable for carburizing and heat treatment processes, where the outer surface is hardened while maintaining core strength and toughness. After case hardening, it offers excellent fatigue strength, impact resistance, and superior wear properties. EN353 steel is commonly used in the manufacturing of gears, pinions, shafts, camshafts, bushes, and other transmission and automotive components that operate under heavy load and high stress conditions.
EN48 Steel
EN31 Steel
EN31 Steel is a high carbon alloy steel grade conforming to BS 970 EN31, equivalent to AISI 52100 bearing steel. It contains high carbon and chromium content, which provides excellent hardness, wear resistance, and fatigue strength. EN31 is specially designed for applications requiring high surface hardness and durability. After hardening and tempering, it can achieve a hardness of around 60–64 HRC, making it ideal for precision components. This steel offers good dimensional stability and high compressive strength. EN31 is widely used in the manufacturing of ball bearings, roller bearings, bearing races, dies, punches, shafts, and other high wear-resistant engineering components.
EN19 Steel
EN19 Steel is a high tensile alloy steel grade conforming to BS 970 EN19, equivalent to AISI 4140 and DIN 42CrMo4 (1.7225). It contains chromium and molybdenum as primary alloying elements, which provide excellent strength, toughness, wear resistance, and good hardenability. EN19 can be heat treated through quenching and tempering to achieve high tensile strength (typically 850–1000 MPa or higher, depending on condition) along with good impact resistance. It also offers good fatigue strength and moderate machinability in the annealed condition. EN19 steel is widely used in the manufacturing of shafts, gears, studs, bolts, crankshafts, axles, connecting rods, and other heavy-duty automotive and engineering components requiring high strength and durability.
EN24 Steel
EN24 Steel is a high strength alloy steel grade conforming to BS 970 EN24, equivalent to AISI 4340 and DIN 34CrNiMo6 (1.6582). It is a nickel-chromium-molybdenum alloy steel known for its excellent toughness, high tensile strength, and superior fatigue resistance. EN24 offers very good hardenability and can be heat treated through quenching and tempering to achieve tensile strength in the range of 850–1000+ MPa depending on section size and treatment condition. It maintains good ductility and impact resistance even at high strength levels. EN24 steel is widely used in the manufacturing of heavy-duty shafts, gears, crankshafts, aircraft components, high tensile bolts, studs, and other critical engineering parts where high strength and reliability are essential.
