310 / 310S STAINLESS STEEL PIPE SUPPLIER BRIEF INTRODUCTION

310 / 310S stainless steel pipe, also known as tp310S ( SS310S ) stainless steel, is an austenitic chromium nickel stainless steel with excellent oxidation resistance and corrosion resistance. Due to the high percentage of chromium and nickel, it has much better creep strength and can continue to operate at high temperatures, with good high temperature resistance.

310 / 310s stainless steel pipe supplier is a hollow long round steel, mainly is widely used in petroleum, chemical, medical, food, light industry, machinery, instrument and other industrial pipeline and mechanical structure parts, etc.

In addition, in bending and torsion strength, the weight is lighter, so it is also widely used to make mechanical parts and engineering structures. It is also used to produce all kinds of conventional weapons, guns and shells.

310 Stainless Steel Pipe vs. 310S Stainless Steel Pipe: A Comprehensive Technical Comparison‌

‌1. Introduction‌

Stainless steel pipes, particularly grades ‌310‌ and ‌310S‌, are critical in high-temperature and corrosive environments. While both belong to the austenitic chromium-nickel alloy family, subtle differences in composition and performance dictate their suitability for specific industrial applications. This article explores the distinctions between ‌stainless steel 310 pipe‌ and ‌stainless steel 310S pipe‌, supported by technical data and application examples.

‌310 Stainless Steel Pipe‌ is austenitic stainless Steel pipe (24–26% Cr, 19–22% Ni, ≤0.25% C) compliant with ‌ASTM A312 TP310/S31000‌. Designed for high-temperature applications (≤1150°C) with superior oxidation resistance, featuring ‌tensile strength ≥515 MPa‌ and ‌carbon content ≤0.25%‌. Primarily used in non-welded heat-resistant components like industrial furnaces and heat treatment equipment.

310S Stainless Steel Pipe‌ is austenitic stainless steel pipe (24-26% Cr, 19-22% Ni, ≤0.08% C) per ‌ASTM A312 TP310S‌, optimized for oxidation/corrosion resistance in welded structures and high-temperature environments (≤1200°C). Applications include chemical processing pipes and furnace components.

‌2. Overview of 310 and 310S Stainless Steel Pipes‌

‌2.1 310 Stainless Steel Pipe‌

‌Stainless steel 310 pipe‌ is a high-temperature alloy containing ‌24–26% chromium (Cr)‌ and ‌19–22% nickel (Ni)‌. Its elevated carbon content (≤0.25%) enhances strength but limits weldability. Key features include:

• ‌Maximum Service Temperature‌: ≤1150°C (2100°F)
• ‌Primary Standards‌: ASTM A312 TP310, ASME SA312
• ‌Typical Applications‌: Industrial furnace parts, heat treatment equipment, non-welded components.

‌2.2 310S Stainless Steel Pipe‌

‌Stainless steel 310S pipe‌ is a low-carbon variant (≤0.08% C) of grade 310, optimized for welded structures and prolonged high-temperature exposure. It retains the same Cr/Ni range but offers:

• ‌Maximum Service Temperature‌: ≤1200°C (2192°F)
• ‌Primary Standards‌: ASTM A312 TP310S, ASME SA312
• ‌Typical Applications‌: Chemical processing piping, radiant tubes, welded furnace components.

‌3. Key Differences: 310 vs. 310S Stainless Steel Pipes‌

‌3.1 Chemical Composition‌

‌Analysis‌: The reduced carbon in ‌310S pipe‌ minimizes carbide precipitation during welding, enhancing corrosion resistance in welded assemblies.

‌3.2 Mechanical Properties‌

‌Analysis‌: While both grades share similar tensile strength, ‌310S pipe‌ exhibits marginally higher ductility (elongation) due to its lower carbon content.

‌3.3 Thermal and Corrosion Performance‌

‌Analysis‌: The ‌310S pipe‌ outperforms grade 310 in continuous high-temperature service due to reduced carbon-induced embrittlement.

‌3.4 Physical Properties‌

‌Note‌: Identical density and thermal/electrical properties make both grades interchangeable in non-critical thermal applications.

‌4. Application-Specific Suitability‌

‌4.1 310 Stainless Steel Pipe Applications‌

• ‌Non-welded furnace components‌ (e.g., burner nozzles, trays).
• ‌Heat treatment equipment‌ requiring high strength.
• ‌Lower-cost alternative‌ where welding is not required.

‌4.2 310S Stainless Steel Pipe Applications‌

• ‌Welded radiant tubes‌ in petrochemical heaters.
• ‌Continuous-operation kilns‌ (e.g., ceramic, glass industries).
• ‌Corrosive chemical processing systems‌ with cyclic thermal loads.

‌5. Selection Guidelines‌

‌6. Conclusion‌

Both ‌stainless steel 310 pipe‌ and ‌stainless steel 310S pipe‌ excel in extreme environments, but their differences in carbon content and weldability define their roles. For welded, high-temperature systems, ‌310S stainless steel pipe‌ is the superior choice, while ‌310 stainless steel pipe‌ remains cost-effective for non-welded, high-strength applications. Engineers must prioritize operating conditions, lifecycle costs, and fabrication methods when selecting between these grades.
