This guide breaks down the technical differences between EN19 (42CrMo4) and EN24 (34CrNiMo6) to help design engineers and procurement teams make the right choice. In the Indian forging and manufacturing sector, EN19 and EN24 are the most frequently specified alloy steel grades. While they share similarities as high-strength materials, choosing the wrong one can lead … Read more

EN24 / AISI 4340 / 34CrNiMo6 Steel When engineering components are subjected to extreme stress, heavy shock loads, and severe wear, standard carbon steels simply cannot survive. For critical applications ranging from aerospace landing gears to heavy-duty automotive crankshafts engineers globally specify the EN24 / AISI 4340 steel grade family. As India’s leading alloy steel … Read more

Every crankshaft, connecting rod, gear and axle begins life long before the forging press – it begins as liquid steel in a melt shop. For automotive forge shops, the quality of that starting material decides everything downstream: die life, rejection rates, machinability, and ultimately the fatigue life of a component that will see millions of … Read more

India has set itself among the world’s most ambitious renewable energy targets, with wind power a central pillar of the plan. Every new turbine installed translates into tonnes of forged steel: tower flanges, main shafts, gearbox internals, bearing rings and slewing components. For the forge shops and ring-rolling units supplying this sector, the starting point … Read more

North India is home to some of the country’s busiest forging belts, from Faridabad, Gurugram and Ghaziabad in the NCR to Ludhiana, Rohtak and Jaipur. For the forge shops, ring rollers and re-rollers in this region, sourcing alloy steel ingots from far-off plants means longer lead times, higher freight, and less flexibility when production plans … Read more

Ring rolling is one of the most material-efficient and microstructurally precise processes in metal forming. Starting from a pierced billet preform – the ring blank – the ring rolling mill reduces the wall thickness, increases the diameter, and controls the height of a rotating ring workpiece between driven rolls. The process produces seamless rolled rings … Read more

Forging is not a single process. The term covers a wide family of deformation operations – each with its own tooling, process parameters, starting material requirements, and failure modes. Of this family, two processes dominate industrial forging worldwide: open-die forging and closed-die forging. They differ fundamentally in how they shape metal, what starting material they … Read more
