Spring Steel is one of the most important safety components of static and dynamic, loaded automobiles and railways. It is meant to absorb the repeated shocks of strain & stress and provide a safe & reliable suspension system.

The grades being manufactured are:

EN45, EN45A, EN48, EN48A, 50CrVMo4, 50CrV4, 52Cr4Mo2V, 55Si7, 65Si7, SUP9, SUP11A, SUP12 etc.

The Carbon Heading Steel (i.e. high quality carbon steel) has better mechanical and processing performance than many other varieties of steel. This steel has good superficial and internal quality, fine and uniform austenitic grain size, good impact toughness, good cleanliness, lower gas content and good response to Heat Treatment. It is used in Auto, Defense, Railways and various other forging and manufacturing industries for various kinds of mechanical structural components, metallic products and tools, motor shaft & pistons rod , case hardened components, forging, drawn wires and nuts & bolts.

The grades being manufactured are:

CK45, SAE1030, 35C8, 45C8, En8, En8A, En8B, En8C, En8D, En9, En15B, En32B, S35C, S45C, S48C, S55C , S58C , Fe -500, Fe-500D etc.

With its unique chemistry and micro structure, and very high inherent machinability it is used in high speed automats for higher productivity and, good surface finish of component and enhanced tool life.

The grades being manufactured are:

EN1A, EN1A(Pb), EN8M, SAE 1141 , SAE1144, SAE1146 etc.

Mainly large and middle specification composite, sectional and various special long products applicable in power transmission towers, bridges, cars and ships, machinery, plant house, holders, frames, civil engineering structural parts etc. Grades being manufactured: AML250PG, AML350PG. (For both normal and high strength applications.

Used in inlet and outlet engine valves. Drill bits for bore wells & rock drilling, Aero engine connecting rod, Valve stems, Valve bodies, Hot working tool. Grades being manufactured: En52, En36C, En30A, AISI410H13.
