Technical Specifications of 310 Stainless Steel Pipe Manufacturer

Product Description

310 Stainless Steel Pipe Manufacturer - High-Temperature Resistant Seamless & Welded Tubing

As a professional 310 stainless steel pipe manufacturer, we specialize in producing premium-grade seamless and welded tubing engineered for extreme thermal stability and oxidation resistance. Our 310 stainless steel pipes comply with ASTM A213/A269/A312 and EN 10216-5:2014 standards, delivering consistent mechanical integrity and precise dimensional control for mission-critical high-temperature applications across furnace systems, heat treatment equipment, and petrochemical reformers. We serve global OEMs, EPC contractors, and industrial fabricators requiring traceable, mill-certified materials backed by decades of metallurgical expertise.

What is 310 stainless steel pipe?

310 stainless steel pipe is an austenitic chromium-nickel alloy containing 24–26% chromium and 19–22% nickel, with a maximum carbon content of 0.08% per ASTM A213 Section 6.1. It exhibits exceptional resistance to oxidation up to 1150°C (2100°F) in continuous service and withstands intermittent exposure up to 1200°C (2190°F), making it the preferred choice for high-temperature structural components where scaling, carburization, or thermal fatigue are primary concerns. Its high chromium and nickel content ensures superior resistance to sulfur-bearing atmospheres and minimizes embrittlement during thermal cycling.

Technical Specifications of 310 Stainless Steel Pipe

Our 310 stainless steel pipes are manufactured to stringent tolerances under ISO 9001-certified processes and verified through full material test reports (MTRs). Key technical parameters include: tensile strength of 515 MPa minimum and yield strength of 205 MPa minimum at room temperature per ASTM A213; elongation of ≥40% in 50 mm; density of 7.98 g/cm³ at 20°C; and thermal conductivity of 14.2 W/m·K at 100°C. All tubes undergo 100% non-destructive testing (NDT) via eddy current or hydrostatic pressure per ASTM E570/E1067, ensuring zero defects in critical weld zones and base metal.

Why Choose Our 310 Stainless Steel Pipe Manufacturing Services?

With over 28 years of focused production experience in heat-resistant alloys, we operate vertically integrated facilities equipped with precision hot-forging lines, cold-drawing benches, and automated TIG/HFI welding cells—all calibrated to meet ASME BPVC Section II Part A requirements. Unlike general-purpose stainless steel suppliers, our metallurgists optimize annealing cycles specifically for 310 grade to preserve grain structure uniformity and prevent sigma phase formation. Every coil and billet is sourced from audited mills with documented ladle analysis, and final products carry dual-certification: chemical composition per ASTM E1086 and mechanical properties per ASTM E8/E21. This commitment enables us to supply 310 stainless steel pipe in diameters from 6.35 mm to 609.6 mm OD, wall thicknesses ranging from 0.5 mm to 40 mm, and lengths up to 12 meters—with custom heat treatment options including solution annealing at 1040–1120°C followed by rapid water quenching.

Frequently Asked Questions

What is the minimum order quantity (MOQ)?

The standard MOQ for 310 stainless steel pipe is 500 kg for stock sizes and 1,000 kg for custom dimensions or special heat treatments. We accommodate prototype orders as low as 100 kg for qualified engineering evaluations, subject to surcharge coverage for setup and testing.

Do you provide material test certificates?

Yes—we issue comprehensive EN 10204 3.1 or 3.2 Material Test Certificates with every shipment. Each certificate includes full ladle chemistry, tensile and hardness test results, grain size evaluation per ASTM E112, and NDT verification records. Third-party inspection by SGS, BV, or TÜV can be arranged upon request.

What is the typical delivery time?

For standard 310 stainless steel pipe in common sizes (OD ≤ 219.1 mm, WT ≤ 12 mm), lead time is 15–20 working days from order confirmation. Custom-welded or cold-drawn configurations require 25–35 days, while large-diameter forged seamless pipes (OD > 323.9 mm) typically ship within 45–60 days due to extended forging and heat treatment cycles.

Can you cut to custom sizes?

Absolutely—we offer precision saw-cutting, plasma cutting, and CNC-controlled orbital machining to exact customer specifications. Tolerances adhere to ISO 2768-mK for length and ±0.2 mm for squareness. Beveling, threading (NPT/BSP), and ID/OD polishing (Ra ≤ 0.4 μm) are available as value-added services.
