K M D Steel And Tube is the leading manufacturers, stockists, supplier and exporter for SS 347/347H Forged Fittings. The SS347/347H fashioned fittings offers a superior consumption opposition over different hardened steel reviews as it can withstand exceptionally oxidizing environment. These scopes of Forged Fittings will in general offer high protection from consumption particularly from media containing chloride. though Stainless Steel 347H is fundamentally an improved rendition of 347 evaluation that offers high protection from substance assault, that makes it appropriate for machining applications. These Forged Fittings are made of best quality raw material and do match national & international quality standard and this helps us to have high demand in the market from our customers. The Forged Fittings are made in different size, dimensions & thickness and this helps us to have high demand in the market from our customers. When it comes to packaging it is done with utmost care because we know the ups and downs faced while import & export of product hencewe make sure that the products are delivered in good conditions without any damages.
