**Maria Pipes and Tubes**, located in Kuala Lumpur, Malaysia, is dedicated to producing and supplying **Stainless Steel 314 Pipes**—top-tier tubing designed for extreme temperatures and corrosive environments. We provide both seamless and welded options, all crafted to meet international standards like ASTM A312/SA312. With a variety of sizes, schedules, and end finishes available, these pipes are tailored for the most demanding industrial applications.
Stainless Steel 314 Pipe is mainly made of iron, chromium (24-26%), nickel (19-22%), and small amounts of manganese, silicon and carbon. This superior alloy provides excellent corrosion resistance, especially in high humidity environments. Technical properties include approximately 205 MPa yield strength, 515 MPa tensile strength, high percentage of expansion, ensure flexibility and durability Advantages of stainless steel 314 pipe include oxidation resistance good, high thermal stability and ease of production, making them ideal for petrochemical, food processing and heat exchangers.

**Stainless Steel 314** (UNS S31400) is a high-alloy austenitic stainless steel that features around 23–26% chromium, 19–22% nickel, and 1.5–3% silicon, with a carbon content of up to 0.25% ([Machine MFG][1], [Metal Zenith][2], [Weston Stainless][3]). These alloying elements give it remarkable high-temperature characteristics. It boasts a tensile strength ranging from 550–750 MPa, a yield strength of about 205 MPa, an elongation of 40%, and a Rockwell B hardness that can reach up to 85 HRB ([SteelPro][4], [Weston Stainless][3]).
