Our Certifications
Steel Sales Co. is a renowned distributor of alloy steel products, refined and manufactured in pristine quality, such as the alloy steel A182 F9 flanges. The trust we have garnered through thousands of clientele has only determined us to strive forward in producing superior quality products and enabled us to adopt innovations in our methods of fabrication, handling, and packaging as well, all towards ensuring that the product remains of higher quality.
Composed primarily of chromium and molybdenum, the alloy steel A182 F9 flanges comprise majorly of the above-mentioned elements and are hence, also called chrome-moly alloys. The unique characteristics of the flanges are due to this increment in the chromium and molybdenum content which adds to the hardening and corrosion resistance of the flanges. There are other elements present in the flanges apart from those mentioned above and these are silicon, sulfur, phosphorus, etc. The additional elements, including chromium and molybdenum, not only stabilize the iron-based alloy but also bestow it with properties it is widely used for. Silicon for instance improves the resistance of the flanges against oxidation, which comes in handy when operating in oxidizing environments.
The most important function of the flanges is to connect the different components and strengthen the system as a whole. To stabilize the entire system, the alloy steel flanges of the grade A182 F9 itself are equipped with strength and toughness. This tensile strength of the flanges enables it to withstand any form of mechanical strain as well as the internal pressure changes it might have to face when connecting different pipes together. The stability displayed by the flanges is not only because of its toughness but can be attributed to the resistance it expertly exhibits against both heat and corrosion. When it comes to corrosion resistance, the F9 flanges are resistant to a number of diverse corrosive agents, be they liquids or gases. Elevated temperatures are also tackled by the heat resistance and thermal stability displayed by the flanges.
The diverse properties coupled with its durability and simplicity has rendered it with applications in vivid industries, a few being, the chemical industry, marine applications, petrochemical, fertilizer industry, the dairy industry, food processing, construction, oil refineries, pulp and paper industry, sugar factories, etc.
Quality assurance is crucial step post-production and one which requires suitable tests to be conducted on the products for the determination of their quality and stability. We strictly carry out tests on every product we manufacture on a regular basis, with inspections organized periodically.
