Quick answer Boron is used in small controlled additions to improve steel hardenability. KSL lists 20MnCrB5 as a boron-alloyed grade for case-hardened and heat-treated engineering applications. Its suitability depends on the complete chemistry, section size and thermal processing. A boron figure on a certificate should be assessed alongside the specified grade and required heat-treatment response. … Read more
Quick answer H11 and H13 are chromium-molybdenum-vanadium hot work tool steels. H11 is often considered where resistance to cracking and toughness are central requirements; H13 is a widely used option for hot forging and die casting where hot strength and resistance to thermal fatigue matter. Selection must also consider steel quality, die geometry and the … Read more
Quick answer A customized steel section covers any requirement outside Kesari Alloys’ standard catalogue – a size that falls between two standard ingot or billet steps, a profile that is neither square, fluted nor round, or a specific hot-top and mould design engineered for a particular part. Getting a feasibility answer takes the same information … Read more
Quick answer SS410 is martensitic and hardenable – the right choice when a part needs strength plus moderate corrosion resistance, such as pump and valve shafts. SS409 and SS430 are ferritic and cannot be hardened by heat treatment – they’re chosen instead for corrosion resistance and formability at lower cost, such as exhaust systems and … Read more
Quick answer Power and heavy-infrastructure buyers typically need chromium-molybdenum grades (ASTM A182 F11, F22, F91) for steam and high-temperature service, IBR-compliant material wherever a boiler or steam pressure part is involved, and full heat-to-certificate traceability to satisfy EPC quality audits – the same technical bar as the oil & gas and valve sector, applied to … Read more
When sourcing forging ingots, billets or blooms in Delhi NCR, check ten things before you compare price: certifications, grade range, size range, melting route, heat number traceability, in-house testing, heat treatment capability, existing vendor approvals, lead time and freight cost. Proximity to your plant matters but only after the material is right. A cheap local … Read more
EN31 SAE 52100 bearing steel is widely used for bearing races, balls, rollers and other precision components where high hardness and fatigue resistance are required. EN31 SAE 52100 bearing steel is a high carbon, high chromium through-hardening steel used for ball and roller bearings. It is known internationally as SAE 52100, AISI 52100 or 100Cr6. … Read more
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
