Teerasil Fittings and Plates, a well-respected manufacturer and supplier based in Bangkok, Thailand, specializes in top-quality Stainless Steel 304 / 304L Forged Fittings that are built to last. These fittings are known for their durability, precision, and outstanding resistance to corrosion. SS 304 is the go-to stainless steel for many applications due to its strength and ability to resist oxidation, while SS 304L, the low-carbon version, offers excellent weldability and reduces the risk of carbide precipitation. Crafted under rigorous quality standards, our forged fittings guarantee leak-proof performance, precise dimensions, and a long lifespan. They find extensive use in industries like chemical processing, oil and gas, food production, pharmaceuticals, and water treatment, where hygiene, strength, and reliability are crucial.

Stainless Steel 304 / 304L Forged Fittings mainly consist of 18–20% chromium, 8–12% nickel, and the balance being iron, with carbon levels of ≤0.08% for 304 and ≤0.03% for 304L. SS 304 is known for its superior strength, while SS 304L excels in weldability and resistance to intergranular corrosion. In terms of mechanical properties, they provide a tensile strength of around 485–515 MPa, yield strength of approximately 170–205 MPa, and good elongation, ensuring toughness across a broad temperature range. Their remarkable resistance to oxidation, chloride stress cracking, and harsh environments guarantees long-lasting performance in high-pressure and demanding industrial piping applications.
