?? High-Performance Stainless Steel for Extreme Heat Applications ??
At Schenk Stahl GmbH , we specialize in high-performance stainless steels that thrive in extreme environments. Today, we’re putting the spotlight on 1.4841 / X15CrNiSi25-21 / TP 314 / (UNS S31400), an advanced high-temperature austenitic stainless steel designed to withstand extreme heat, oxidation, and aggressive industrial environments.
If you're looking for a material that delivers exceptional high-temperature strength, oxidation resistance, and long-term durability, then 1.4841 / X15CrNiSi25-21 / TP 314 / (UNS S31400) is your perfect solution!
?? Why 1.4841 / X15CrNiSi25-21 / TP 314 / (UNS S31400)?
Unlike standard stainless steels, 1.4841 / TP 314 (UNS S31400) is engineered for high-temperature environments, making it ideal for applications where other materials fail.
? High Chromium (Cr) Content (24-26%) – Forms a strong passive layer, providing outstanding oxidation and scaling resistance up to 1150°C (2100°F).
? Nickel (Ni) Content (19-22%) – Enhances mechanical strength and structural stability at extreme temperatures.
? Silicon (Si) Addition (~1.5%) – Improves oxidation and carburization resistance, making it ideal for furnace and heat treatment applications.
? Excellent Mechanical Properties – High tensile strength and creep resistance for long-term exposure to high temperatures.
? Good Weldability – Can be welded using standard welding techniques without post-weld heat treatment.
Industry Standards & Norms:
? Tubes: EN 10216-5 / SEW 470, EN 10296-2 / DIN 17458, ASTM A276M
