Every grade we stock — with the data you need to choose.

EN8 is an unalloyed medium-carbon steel and one of the most widely used general-engineering grades in India. It offers a useful step up in strength and wear resistance over mild steel while remaining easy to machine, and it can be through-hardened or induction-hardened where harder, more wear-resistant surfaces are needed. It is the classic choice for shafts, studs and machined parts that are not heavily stressed but must outlast plain mild steel.

EN9 is a higher-carbon plain carbon steel that delivers greater strength, hardness and wear resistance than EN8. It is chosen where parts must carry more load or resist surface wear, and responds well to heat treatment for a tougher, harder finished component — the natural next step up from EN8 in the carbon-steel family.

C45 is the European-standard medium-carbon engineering steel — chemically and mechanically almost identical to EN8 and AISI 1045, and used interchangeably with them in much of Indian industry. It offers good strength and machinability at low cost, and can be flame- or induction-hardened where surface wear resistance is needed. If your drawing calls for C45, 1045 or S45C, we supply this grade against any of those designations.

EN19 is a 1 % chromium-molybdenum direct-hardening alloy steel — one of the most popular high-tensile engineering steels worldwide. Known internationally as AISI 4140 or 42CrMo4, it combines high strength, good ductility and wear resistance, and is typically supplied hardened and tempered (the "T" condition) ready for machining into demanding components. If you need real high-tensile performance without the price of EN24, this is the grade.

AISI 4140 is the American designation for the same chromium-molybdenum direct-hardening alloy steel known in the UK as EN19 and in Germany as 42CrMo4. It is one of the most-specified high-tensile engineering steels in the world. We stock the grade against any of those designations — useful when you are working to an American drawing, a European technical specification, or a buyer's PO that explicitly calls out "4140." Mechanical properties and applications are as for EN19.

EN24 is a nickel-chromium-molybdenum high-tensile alloy steel offering an outstanding combination of strength and toughness, even in large sections. Equivalent to AISI 4340 and 34CrNiMo6, it is the grade engineers reach for when EN19 alone is not strong or tough enough — typically supplied hardened and tempered for the most heavily loaded components. In large-section bars over 100 mm, it noticeably outperforms EN19 because the nickel deepens hardenability through the whole cross-section.

EN31 is a high-carbon, high-chromium through-hardening bearing steel — the global standard for bearings, rollers and precision wear parts. Known as AISI 52100, 100Cr6 or SUJ2, it reaches very high hardness after hardening with excellent wear resistance and a fine, clean microstructure. Internal cleanliness matters enormously for fatigue life — which is exactly where our in-house ultrasonic testing earns its keep on this grade.

SAE 52100 is the American designation for the high-carbon chromium bearing steel known as EN31 in the UK, 100Cr6 in Germany and SUJ2 in Japan. It is the same grade, called by its American name — and is the global standard for ball and roller bearings, rolling-contact components and precision wear parts. Because bearing-steel cleanliness is fatigue-critical, every bar dispatched is ultrasonically tested to ASTM A388 in our yard. Mechanical properties and applications are as for EN31.

EN36C is a high-nickel chromium-molybdenum case-hardening steel. After carburising it develops a very hard, wear-resistant case over an exceptionally tough, shock-resistant core. Compared to plain EN36 (655M13), the molybdenum in EN36C adds hardenability and improves core strength — making it the grade for the most heavily stressed gears and pins, including aircraft and crankshaft applications.

EN353 is a nickel-chromium-molybdenum case-hardening steel with low carbon but good hardenability. After carburising it gives a hard, wear-resistant surface and a tough core with good fatigue strength — making it a mainstay for automotive transmission gears and shafts. Reliable, predictable response to heat treatment is its real strength, which is why high-volume automotive ancillaries rely on it.

SAE 8620 is a low-alloy nickel-chromium-molybdenum case-hardening steel and a global standard for carburised gears and shafts. It hardens to a tough, wear-resistant case while keeping a ductile core, machines well in the supplied condition, and benefits from one of the most consistent supply chains in engineering steel — which is why automotive and machinery OEMs specify it worldwide.

20MnCr5 is a manganese-chromium case-hardening steel valued for its excellent combination of surface hardness and core strength after carburising. Its fine grain and very consistent hardenability make it a preferred grade for precision automotive and machinery gears — where heat-treated dimensional control matters as much as the mechanical numbers.

S7 is a shock-resisting air- or oil-hardening tool steel — the AISI "S" group's most versatile member, valued for exceptional impact toughness combined with the highest hardenability of the shock-resisting grades. Where a high-carbon, high-chromium grade like D2 would chip under repeated impact, S7 holds. It is also notable for hardening with minimal distortion, which makes it forgiving in the tool room.

D2 is a high-carbon, high-chromium air-hardening cold-work die steel — the go-to grade for blanking, forming and shearing tools that demand maximum wear resistance. Its high chromium and carbon content produces a microstructure rich in hard carbides, giving it excellent abrasion resistance and dimensional stability through hardening.

D3 is the high-carbon, high-chromium oil-hardening cold-work tool steel — D2's older cousin, without molybdenum or vanadium. It develops a very hard, wear-resistant microstructure and is widely used in India where excellent abrasion resistance and edge-holding matter more than peak toughness. Most blanking and forming dies for high-volume runs in Indian tool rooms are still made in D3.

H11 is a chromium-molybdenum-vanadium hot-work tool steel with excellent toughness — the more impact-resistant member of the H11/H13 pair. It retains strength and resists softening at elevated temperatures, making it the steel of choice for die-casting dies, hot-extrusion tooling and forging dies that take high-shock loading.

H13 is the most widely used hot-work tool steel in the world — a chromium-molybdenum-vanadium grade that combines high hot strength, excellent resistance to thermal fatigue, and good wear resistance. It is the default specification for aluminium die-casting dies and hot-extrusion tooling, and is the tool steel a buyer means when they say "industry-standard hot-work."

P20 is the global standard for plastic injection-mould tooling. It is a chromium-molybdenum-manganese alloy steel supplied pre-hardened to 28–34 HRC — ready to machine directly into a mould cavity without further heat treatment. Its outstanding polishability gives excellent surface finish for transparent plastic parts, and the pre-hardened condition removes distortion risk from the tool-making process entirely.

DB6 is a nickel-chromium-molybdenum-vanadium die-block steel, specifically engineered for forging dies, hammer dies and large hot-work tooling that takes repeated heavy impact. The high nickel content gives it exceptional toughness and uniform hardness through large sections, and it is usually supplied in the pre-hardened condition (typically 360–430 HB / ~ 39–44 HRC) ready for the die-sinker to start cutting. It is the upgrade to the older DIN 2713, with significantly better through-hardening and tempering response.

OHNS — short for Oil-Hardening Non-Shrinking, designated AISI O1 — is a general-purpose cold-work tool steel. It hardens in oil with very little dimensional change ("non-shrinking"), making it the practical choice for accurately sized tools, dies and gauges that must hold their shape after heat treatment. Forgiving to heat-treat and easy to machine in the annealed state, it remains a stockroom staple in tool rooms across India.
