K M D Steel And Tube is the leading manufacturer, supplier, stockists& exporter for SS 317/317L Forged Fittings.The amalgam 317-317L is made out of molybdenum content. It has austenitic structure with some measure of carbon. Notwithstanding Chromium and Nickel its consumption obstruction capacity is expanded even in the concoction lessening zone.The carbon content offers protection from grain limit precipitation or sharpening. by and large this evaluation is non-attractive in nature when subject to the strengthening procedure. be that as it may, cold working tasks make it attractive in nature. This offers higher downer pliable and worry to break properties. These forged Fittings are sold in the market at customer affordable prices. When it comes to packaging it is done with great care because we know the ups and downs faced while import & export of product hence we make sure that the products are delivered in good conditions without any damages. The Forged Fittings are made of best quality raw material and also consists of features like longer life, anti corrosiveness, smooth finish, high ductility and more all this helps the product to match national & international quality standard and have higher demand in the market from our consumers.
