Hebei All Trust Steel Co., Ltd delivers industrial-grade 310s stainless steel tubing engineered specifically for extreme thermal applications. Our tubing has outstanding concentrations of chromium (24-26%) and nickel (19-22%) that retain structural integrity at continuous operation temperatures up to 1100°C. Annual capacity is above 15,000 tons with 100% hydraulic testing compliance. Every batch is manufactured to ASTM A213, ASTM A269 and ASME SA213 standards, and is subject to rigorous PMI analysis, eddy current testing and intergranular corrosion verification, assuring zero compromise in furnace tubes, boiler components and petrochemical cracking systems.
Our precision seamless cold drawn method ensures full wall density with ±0.05 mm tolerance in dimensions. Strict solution annealing at every tube 1040°C-1150°C eliminates the development of hazardous sigma phase.

When typical austenitic grades surrender to thermal stress, this product is the best option. The letter "S"signifies a regulated low carbon content (max. 0.08%) that significantly reduces carbide precipitation during welding and manufacturing.
This particular composition addresses three key industrial concerns. It first avoids catastrophic oxidation scaling which kills ordinary tubing beyond 800°C. Secondly, it retains its mechanical strength throughout cyclic heating and cooling in radiant tubes. Third, it resists carburization in carbon rich petrochemical environments where grades 304 and 316 quickly degrade.
Materials that will not fail under pressure are needed for your furnace burner assemblies, combustion chambers and thermal power heat exchangers. This tubing ensures ongoing performance in situations when equipment failure equals production stoppage and safety concerns.

This tubing's superior performance is a function of its balanced and exact composition. up to 26% chromium concentration. The result is a stable chromium oxide layer that is automatically formed, protecting the base metal from the assault of the atmosphere.
Nickel content 19-22% stabilises the austenitic structure and prevents the phase change, which causes embrittlement. The carbon maximum is .08% for resistance to intergranular corrosion in the weld zones.
The mechanical parameters include a minimum tensile strength of 515 MPa and a yield strength of 205 MPa at ambient temperature. More crucially, it preserves functional strength at temperatures when rivals lose their structure.
The tube is non-magnetic in the annealed form, which is important for several electromagnetic applications. It has a density of 7.98 g/cm³ and a melting range of 1400°C –1450°C, providing further confidence for harsh situations.

Our production process begins with 100% virgin stainless steel from ISO-certified mills. Spectrographic analysis verifies every heat's chemical composition before processing begins.
Precision cold drawing achieves tight dimensional tolerances while maintaining uniform wall thickness. Advanced eddy current testing detects microscopic defects invisible to conventional inspection methods.
Each production batch undergoes specialized high-temperature tensile testing and grain boundary analysis. We perform ASTM A262 Practice E intergranular corrosion testing to guarantee sensitization resistance.
Mechanical workability is shown by flattening tests, flare tests and flange tests. Leak proof integrity is ensured by hydrostatic testing at 150% of operating pressure.
Before shipping, rigorous PMI scanning checks alloy composition. Third party inspection services are all accepted and fully supported (SGS, TUV, BV). All orders are supplied with comprehensive EN 10204 3.1 certifications for material traceability.
Understanding that industrial thermal systems require precise specifications, we offer comprehensive customization services. Fixed-length cutting accommodates your installation requirements without material waste.
Heavy wall thickness configurations suit high-pressure thermal applications where standard dimensions prove insufficient. Specialized shot-blasted descaled surfaces provide optimal preparation for welding or coating operations.
Our laser cutting and drilling services create precise holes and slots per your technical drawings. Pipe bending and threading eliminate secondary operations in your facility.
End bevelling preparation assures delivery suitable for welding. We provide a variety of surface finishes from satin polish to 8K mirror finish to suit different aesthetic and practical requirements.
We handle orders for specialised requirements with adjustable MOQ, from single-tube prototypes to multi-ton industrial projects.

In industrial thermal processing, this tubing serves as the backbone material for furnace muffles, radiant tubes, and burner components. The alloy withstands continuous oxidizing atmosphere exposure without the structural deformation that sidelines production equipment.
Petrochemical and chemical refining operations depend on it for catalytic recovery systems, flare tips, and steam boiler hangers. Here, combined resistance to high-temperature corrosion and pressure becomes non-negotiable for safety and operational continuity.
Power generation and waste incineration facilities implement it in superheater tubes and coal gasifier components. These demanding environments subject materials to complex combinations of extreme heat and abrasive particulates, requiring superior creep strength and slag corrosion resistance.
Other uses include heating elements, thermal processing equipment, kiln structures and high temperature exhaust systems where 310s stainless steel tubing minimises downtime due by thermal fatigue.
Material integrity is understood to be dependent on handling and hence we have strict guidelines for export packing. The tubes include individual plastic end covers to protect the holes from contamination and damage.
Hexagonal bundles are entirely enclosed in waterproof woven bags and secured with heavy strength metal strapping. Maximum Impact and Moisture Protection for Sensitive Shipments Fumigated Plywood Cases
Our strategic shipping destinations include Shanghai, Ningbo, Tianjin, Qingdao and Shenzhen, provide efficient delivery worldwide. We support FOB, CFR, CIF and DDP trading terms as your logistical option.
Mixed Container Loading Our mixed container loading of pipes, fittings, flanges and valves gives you the opportunity to optimise your procurement efficiency. Good shipping documents assist seamless customs clearance across the globe.
