Product Description

Grade 310 is an austenitic stainless steel renowned for its exceptional high-temperature properties, good ductility, and weldability. Type 310 stainless steel pipes are specifically designed for elevated temperature applications. The high chromium and nickel content provides these pipes with excellent resistance to corrosion and oxidation, as well as superior strength retention at temperatures up to 2100°F (approximately 1150°C). This superior composition makes it outperform 304 or 309 stainless steel pipes.

Core Advantage: More Than Stainless Steel – The Epitome of Heat-Resistant Alloys

When temperatures exceed 800°C, ordinary stainless steels begin to oxidize, deform, and lose mechanical properties rapidly. However, the 310 series, with its unique 25% Chromium (Cr) and 20% Nickel (Ni) optimal composition, maintains structural stability and integrity during continuous service up to 1150°C . This is due to the dense Cr₂O₃ oxide film formed on the surface by the high chromium content, acting as an inseparable "refractory armor" that effectively blocks further erosion by oxygen, sulfur, and corrosive media .

We provide more than just steel pipes; we offer the core guarantee of safe production in your ultra-high temperature applications.

Why Choose 310/310S?

1、Extreme Oxidation and Carburization Resistance: 

High chromium (24.0-26.0%), combined with silicon (≤1.5%), provides excellent performance in oxidizing atmospheres and resistance to mild carburizing and sulfidation environments, widely used in fluidized bed combustors and petrochemical heaters .

2、Superior High-Temperature Creep Strength:

 As an austenitic face-centered cubic structure, 310 exhibits excellent creep strength and enduring plasticity at elevated temperatures . The TP310H grade, with its higher carbon content, further enhances stress-rupture properties, making it ideal for ultra-supercritical boilers and aero-engine components .

3、Broad Service Temperature and Media Range: 

From cryogenic temperatures of -268°C to blazing heat up to 1150°C, the 310 series demonstrates exceptional toughness . It resists fuming nitric acid at room temperature and fused nitrates up to 425°C, even showing better resistance to chloride stress corrosion cracking than 304/316 in marine environments .

4、Good Workability and Weldability: 

Despite being a heat-resistant alloy, 310 maintains the good ductility and weldability of austenitic steels. It can be welded using standard processes like TIG and MIG, facilitating the fabrication of complex components .
