Three companies. One promise: certified steel, on time.

When you buy from the Arihant Group, your material never changes hands between vendors. Stocking, cutting, forging, heat treatment, machining and testing all happen within the group — so there is one purchase order, one quality system, and one partner answerable for the result.
Arihant Ispat
Stockist & Exporter of Special Steels
Carbon, alloy, stainless, duplex and nickel-alloy steels — plus aluminium, copper and brass — held in ready inventory, so your material ships in days, not mill lead-times. Band saws and state-of-the-art cutting machines cut every section to your exact length, and every bar leaves with its mill test certificate.
Kulpak Steel & Forgings Pvt Ltd
ISO 9001:2015 · Forging & Machining
Open and closed die forgings made to order — shafts, rings, flanges, gear blanks and shaped parts to your drawing — delivered proof-machined or fully finished from the in-house machine shop.
Rishab Heattreaters
ISO 9001:2015 · Heat Treatment
Complete heat treatment — from case carburizing to solution annealing — with hardness, case depth and microstructure verified on the group's laboratory before any batch moves on.

Six stages. One chain of custody.

Every hand-off between vendors adds days, freight and paperwork risk. Inside the group there are no hand-offs — your material and its documentation move through all six stages under one roof, and you deal with exactly one supplier.
Stock & cutArihant Ispat
Your grade is already on the rack — 80+ grades from approved mills, cut to your exact length on band saws and state-of-the-art cutting machines. Flat products slit or cut-to-length to your blank size.
ForgeKulpak
Open & closed die forgings, rings and flanges — shaped to near-net size, saving you material and machining time.
Heat treatRishab
Every common cycle under one roof — no need to route material to a second heat-treater.
MachineKulpak
Delivered ready to use — proof-machined or fully finished on VTLs to Ø1300 mm and lathes to 6 m.
Test & certifyGroup laboratory
Chemistry, strength, hardness and internal soundness proven in-house — your test report ships with the material, not weeks after it.
EXPANDINGA new plant is coming up at Vasanthanarasapura, Tumakuru — a new line of machinery and equipment is under installation, adding fresh capacity across the group’s cutting, forging and machining operations.

Sourced only from approved mills

The certificate is only as good as the mill behind it. Every bar, plate and coil we stock comes from an approved primary or special-steel producer — domestic and international — so the chemistry on the paper is the chemistry in the steel.

Properties you can put a certificate behind

Heat treatment is where a component earns its strength — and where an unverified cycle can hide a failure. Every batch at Rishab is checked for hardness, case depth and microstructure on the group's own laboratory before it leaves.

Quality & testing laboratory

Sending samples to an outside lab adds a week to every dispatch. The group laboratory — shared by Kulpak and Rishab — verifies chemistry, strength, hardness and internal soundness in-house — so certification never delays delivery, and every claim on the certificate was measured on our own floor.
