Stainless Steel Threaded Plug Manufacturer in Mumbai, India

This specification for ASTM A182 SS Threaded Hex Plugs covers forged or rolled alloy and stainless steel pipe flanges, forged fittings, and valves and parts. These threaded pipe plug dimensions are designed for high-temperature service. After hot working the threaded insert plug, the forgings must be cooled to a specific temperature before heat treatment. This process must meet standard requirements such as heat treatment type, austenitizing/solution temperature, cooling media, and quenching. The materials for the Threaded Hex Plug must conform to the required chemical composition for elements like phosphorus, silicon, carbon, manganese, nickel, chromium, molybdenum, columbium, and titanium. The material used for the Screwed Hex Plug must also meet the mechanical property requirements for the ordered grade, including tensile strength, yield strength, elongation, and Brinell hardness. All H grades and grade F 63 specified for the BS3799 Screwed Forged Hex Plug must be tested for average grain size.

The SS 310 Threaded Square Plug grades typically contain about 25% chromium and 20% nickel, making the Stainless Steel Threaded Square Plug highly resistant to oxidation and corrosion. Grade 310S Forged Hex Plug is a lower carbon version of SS310, making it less prone to brittleness and sensitization. The high chromium and medium nickel content enable the Grade 310S BS3799 Screwed Forged Hex Plug to be used in reducing sulfur atmospheres containing hydrogen sulfide (H2S). These Threaded Fittings Hex Plugs are widely used in moderately carburizing atmospheres, often encountered in petrochemical environments.
