ARK Stainless Inc. is a reliable manufacturer and supplier of top-grade Alloy Steel Buttweld Fittings, engineered with superior chemical compositions to deliver high strength, excellent hardness, and exceptional durability. These fittings are widely used in demanding environments due to their outstanding corrosion resistance and thermal stability, making them suitable for both high-pressure and high-temperature applications.
Our Alloy Steel fittings are crafted using elements such as carbon, nickel, aluminum, manganese, titanium, and iron, and are available in multiple forms including Seamless, Welded, Fabricated, and ERW. These fittings feature key mechanical and physical properties such as thermal conductivity, electrical resistivity, density, high melting point, elongation, and proof stress. Manufactured in accordance with international standards like ASTM B366 / ASME SB366 and dimensional norms including ASME B16.9, B16.28, and MSS-SP-43, our Alloy Steel Buttweld Fittings are offered in various sizes, thicknesses, and surface finishes to suit diverse industrial requirements. These fittings are widely applied in power generation, petrochemicals, refineries, and high-temperature processing plants.

Alloy steel Buttweld Fittings is applicable in many of the industries and general works like pharmaceutical industry, gas processing, chemical equipment, and pharmaceutical equipment, offshore oil drilling industry, industry, heat exchangers, condensers, seawater equipment, petrochemical industry, power generation industry, food processing, paper industry, pulp industry, rail components, road transportation components, pumps, shafts, and military applications as well. Alloy steel Buttweld Fittings is made with several of the properties for the use in the annealed temperatures and chloride environments without any deformation to the fittings. These fittings are resistant form the entire general corrosion like crevice corrosion, stress corrosion, cracking corrosion, pitting corrosion, and impact corrosion as well.
These fittings have to undergo many of the tests after the production from the industry like flaring test, mechanical test, hardness test, macro test, micro test, hydrostatic test, radiography test, ultrasonic test, and flattening test as well.
