Ismt Public Limited

Viman Nagar, Pune, Maharashtra

ISMT is an established market leader in the production of special engineering steels. We produce carbon, alloy and martensitic stainless steel bars with a special emphasis on ultra-clean steels, free machining steels, bearing steels, and on other specially engineered steel grades. With over 15 years of experience in the manufacture of special steels our strength lies in our ability to produce very clean steels consistently and cost effectively; to produce hard to manufacture free machining steels; to develop and custom produce steels that meet specific mechanical or metallurgical requirements; and to deliver small lots of steels.

ISMT manufactures cold-drawn precision seamless tubes for use in hydraulic pressure lines. These tubes are specially designed to withstand high static as well as dynamic loads and offer a long lasting, reliable solution. All ISMT tubes embody over 20 years of experience in the manufacture of Seamless tubes. The quality of tubes that we manufacture for hydraulic pressure lines fully reflects experience.

Rifled tubes are used in boilers to provide highly energy efficient means of heat transfer. The presence of the internal rifling induces centrifugal forces in the mass flow thereby separating the water from the steam fraction and forcing the water towards the tube wall. As a result of this phenomenon and the increase in internal surface the following advantages accrue: Improved heat transfer rate even at higher steam quality levels Very good heat transfer even at low mass flux levels Reduction in mean metal temperature of the tube wall Ability to increase heat transfer rate by optimizing rifling geometry

Our research and product development teams have worked closely with our customers to develop a very wide range of products. Size range extending upto 273 mm dia (10 inches) Multi-rifled tubes (both A and B series) Creep resistant T � series tubes including T1, T5, T11, T22, T91, T92 and T23 grades Long length tubes upto 25.5 meters Cold drawn tubes

ISMT Limited has developed a range of specialized tubes for the manufacture of hydraulic cylinders. The steel used for the manufacture of these tubes is produced inhouse. The steel is produced through the electric arc furnace route, is fully killed and vacuum degassed ensuring a very low inclusion rating. As a result, cylinders produced from these tubes have a blemish free surface finish and a longer service life. Furthermore, these tubes are produced through the Assel Mill route resulting in very tight dimensional tolerances thus minimizing the requirement for final machining. Hydraulic CylindersDepending on the finishing operation to be used by the customer for producing the cylinder, ISMT Limited supplies hydraulic cylinder tubes in three different categories (Type I, Type II, Type III). These categories are distinguished not only by the dimensional tolerances of the tubes but also by the excess material left for the finishing operation. Within each of these categories, tubes can be supplied from four standardized grades of steel. Alternatively, the company can make tubes from a customized grade of steel to meet the specific requirements of a customer.
