Phanuphong Steel and Plates stands out as a top-notch manufacturer and supplier of premium Carbon Steel Forged Fittings, proudly based in Bangkok, Thailand. Known for their precision-engineered products, they cater to a diverse array of industries, including oil & gas, petrochemical, power generation, and heavy engineering. Their forged fittings comply with both international and industrial standards like ASTM A105 and ASME B16.11. With a commitment to strength, durability, and resistance to high pressure and temperature, Phanuphong Steel guarantees reliable performance in demanding applications, earning a solid reputation for carbon steel solutions across Thailand and Southeast Asia.
When it comes to Carbon Steel Forged Fittings, they are usually crafted from ASTM A105 material, which includes carbon (up to 0.35%), manganese (0.60–1.05%), phosphorus (≤0.035%), sulfur (≤0.040%), and some trace elements like silicon. These fittings boast impressive mechanical properties, featuring a minimum tensile strength of 485 MPa, a yield strength of at least 250 MPa, and a minimum elongation of 22%. They are specifically designed to endure high-pressure and high-temperature conditions, providing exceptional toughness and ductility. The forging process improves grain flow, mechanical strength, and fatigue resistance, making them ideal for critical and high-stress piping systems.
