Excellence & expertise in manufacturing stainless steel wires & bars since 1990
Tru Tuf Bars


Venus, the leading stainless steel bar manufacturer and exporter in India, has vast experience in the manufacture of TRU-TUF – an AISI 630 type martensitic and precipitation hardening stainless steel commonly referred to as 17-4 PH.

These steels are used for critical operations that require superior corrosion resistance and high impact strength upto a temperature of 6000F. As these steels are hardened at low temperatures by single ageing treatment, probability of distortion is very less. Our TRU-TUF bars strictly adhere to the above requirement and contain 17% chromium, 4% nickel and 3-5% copper.

The wide area of application includes Oil Field, Aircraft Fittings, Pump Shafts, Reactor Components, Valve Stems, Hydraulic Fittings, Food Industry Equipment’s and Mills. The hardening required for TRU-TUF bars is stringent but is easily catered to by our in-house state-of-the-art heat treatment facilities. The bars are supplied as per H900 / H925 / H1025 / H1075 / H1100 / H1150 / H1150 D / H1150 M heat treatment hardenings. Our TRU-TUF bars are manufactured in the range of 6.35 mm (¼”) to 152.4 mm (6”) diameter.

Irrespective of the size of the supply lot, all our bars are tested at critical conditions to satisfy our in-house quality control and quality assurance program accredited by global certifications.
