Chanchai Stainless of Bangkok, Thailand is a prime manufacturer and supplier of high-quality stainless steel products, such as Stainless Steel 314 tubing. Renowned for its superior high-temperature strength and resistance to oxidation, Stainless Steel 314 tubing is well suited to rigorous industrial uses. Chanchai Stainless provides these tubes in a range of sizes and specifications for various industries such as heat treatment, furnace production, petrochemical, and power generation. With its emphasis on quality, precision manufacturing, and timely delivery, Chanchai Stainless has established itself as a reliable supplier of stainless steel tubing solutions across Thailand and the region.
Stainless Steel 314 tubing contains about 24–26% chromium, 19–22% nickel, and up to 2.5% silicon, which increases its resistance to oxidation and high-temperature stability. The tubing has superior mechanical properties, such as a yield strength of approximately 620 MPa and tensile strength of approximately 310 MPa. The tubing can withstand its structural capacity and scaling resistance at temperatures of up to 1150°C. The composition of the alloy provides excellent thermal fatigue and oxidation resistance, hence in environments that are severe and have a high temperature.
