Rajdhan Metal is a reputable producer of Square head carbon steel plugs. The ASME B16.11 Threaded Plug has adequate resistance to a variety of oxidizing conditions as well as exceptional resistance to chloride-ion stress-corrosion cracking. After sufficient heat treatment, threaded square head plugs exhibit good stress-rupture efficacy and low creep rates under high stresses at temperatures. They are also highly resistant to chemical corrosion and oxidation. Our ASME B16.11 Square Head Plugs are offered to our esteemed clients in a variety of diameters (d), wall thicknesses (w), and sizes (nom. pipe size), as well as in bespoke forms (per client request or order) and at very reasonable costs.
What is Square Head Plug?
A standard for forged or rolled alloy and stainless steel pipe flanges, forged fittings, valves, and components are ASTM A105 Carbon Steel Square Head Plugs. These threaded pipe plug specifications are typically employed in high-temperature applications. These forgings must be chilled to a certain temperature before undergoing heat treatment after being hot worked to create the threaded insert plug. In line with certain specifications of the standard, such as heat treatment type, austenitizing/solution temperature, cooling media, and quenching, this might be done on the threaded plug made in accordance with DIN 908 specification. Phosphorus, silicon, carbon, manganese, nickel, chromium, molybdenum, columbium, and titanium are needed chemical elements whose chemical compositions must be met by the materials used to make carbon steel square head plugs. The raw material used to make Carbon Steel Square Head Plugs must meet the specifications for the grade specified, including those for tensile strength, yield strength, elongation, and Brinell hardness.
About 25% chromium and 20% nickel are often found in the alloy of carbon steel square head plugs. These components provide the Carbon Steel Square Head Plugs with a high level of oxidation and corrosion resistance. The Forged Carbon Steel Square Head Plugs are suitable for use in lowering sulphur atmospheres including H2S or hydrogen sulphide due to their high chromium and medium nickel content. As a result, these Carbon Steel Square Head Plugs are frequently utilized in moderately carburising situations, such as those seen in petrochemical settings.
