Our Certifications
Steel Sales Co is a highly acclaimed and esteemed fabricator and distributor of alloy steel products such as the alloy steel A234 WP91 buttweld pipe fittings. The alloy products we deliver are sure to fulfill all the customer expectations in terms of both quality and cost. Modern machinery is employed for the purpose of assembling pure quality raw materials to fabricate products of supreme quality.
Constituting chromium in comparatively greater quantities than other grades of fittings, the alloy steel flanged fittings of the grade A234 WP91 are chrome-moly alloys. With 8-9.5% of chromium, the corrosion resistance properties imparted by this element are enhanced and so is the hardness it provides the alloy with. Silicon and sulfur are other two elements added to the alloy to grant it oxidation resistance and machinability. Sulfur is beneficial for machining the alloy but with an increase in its fraction, the ductility of the fittings is reduced, and hence, the proportion of sulfur is kept at a minimum. The amount of carbon is also minimized so as to improve the corrosion resistance of the alloy against intergranular corrosion.
With the oxidation resistance of the alloy steel A234 WP91 grade spigot pipe fittings, oxidizing environments are faced without worrying about the alloy undergoing deterioration caused due to oxidation. The tensile strength of the fittings is also worth mentioning as they play an important role when dealing with high pressure and high physical strain situations in aggressive conditions. The fittings display excellent resistance against corrosive agents such as acids and liquid solvents while retaining their efficient functioning. The hot working properties manifested by the A234 WP91 grade enable it with good weldability and make it easier for it to undergo other heat treatment methods. Along with the heat treatable characteristics of the alloy fittings comes the stability it exceptionally displays across a wide range of temperatures, be it excessively elevated temperatures.
Applications in which the alloy steel buttress fittings belonging to the grade A234 WP91 are extensively used are breweries, pulp, and paper industries, power plants, food processing, petrochemical, fertilizer industry, water supply system, etc.
The trust which we have received since our establishment from clientele is due to the quality of products we have supplied and to avoid any sort of compromises or damaged products to be delivered, a number of tests are conducted on the products we manufacture, before they are shipped off.
