SS 310 Jumper exporter in UK
Last Updated: July 2026
Quick Answer
SS 310 Jumper is a high-chromium, high-nickel stainless steel tube assembly used to connect instrumentation components in high-temperature process and furnace-monitoring applications up to 1150°C. Manufactured to ASTM A312 and ASME B31.3.
SS 310 Jumper exporter in UK is engineered for instrumentation and process piping installations operating at elevated temperatures, where standard 304 or 316 fittings would lose strength or suffer oxidation. Manufactured from high-chromium, high-nickel austenitic stainless steel grade 310, these jumper assemblies maintain their integrity in furnace monitoring, heat-treatment, and high-temperature process lines.
SS 310 contains 24-26% chromium and 19-22% nickel – significantly more of both elements than 304 or 316 – giving it outstanding resistance to oxidation and scaling at temperatures up to 1150°C, along with good resistance to carburization and thermal cycling. This makes SS 310 jumpers suited to environments where corrosion resistance alone is not enough and sustained high-temperature strength is required.
Manufactured to ASTM A312 and ASME B31.3, SS 310 jumpers are available with the same range of end connections as our other jumper grades – NPT threaded, BSP threaded, socket weld, and compression fitting – for straightforward integration into existing high-temperature instrumentation and process skid designs.
UK buyers, including those supplying North Sea offshore operators, typically expect SS 310 Jumper to meet both ASME and British/EN standards for offshore and process applications.
Shipments to the UK are documented to satisfy both ASME and EN standard cross-references, a common requirement for offshore and refinery procurement teams.

Manufacturing Process & Heat Treatment of SS 310 Jumper
Annealing
SS 310 jumper tubing and fittings are solution-annealed at 1040°C to 1150°C, the highest range among our jumper grades, to ensure a fully austenitic structure capable of sustained high-temperature service.
Forging
Fitting bodies are forged from SS 310 bar stock at 1150°C to 1250°C. The high chromium and nickel content increases hot-working resistance, requiring higher forging temperatures and tighter process control than 304 or 316.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1040 - 1150 | Water | Increase hardness and restore austenitic structure |
| Tempering | 300 - 600 | Air | Reduce brittleness and improve toughness |
| Stress Relieving | 600 - 700 | Air | Relieve residual stresses from welding or machining |
These elevated processing temperatures reflect SS 310's role as a high-temperature grade, ensuring jumpers retain oxidation resistance and strength through repeated thermal cycling in service.
