Sumer Metal Industries Pvt. Ltd. manufactures precision Stainless Steel 310 needle tubes engineered for demanding, high-temperature and corrosive environments. Produced using controlled cold-drawing and finishing processes, our SS310 needle tubes deliver tight dimensional tolerances, excellent straightness and a bright surface finish — all critical for instrumentation, thermocouple sheaths, burners and other precision applications.
As a trusted supplier and exporter, Sumer Metal Industries ships SS310 needle tubes to Oman, Qatar, Saudi Arabia, the United Arab Emirates, Kuwait, Spain, Germany, the United States, Canada and multiple regions across Africa. We provide export-grade packaging, mill test certificates (MTCs), and the documentation buyers need for smooth customs clearance and on-time delivery.
Stainless Steel 310 (UNS S31000) is valued for its high chromium and nickel content which gives it outstanding resistance to oxidation and scaling at elevated temperatures. For needle tube applications that face sustained high heat or cyclic thermal exposure, SS310 offers superior stability and longer service life than standard austenitic grades.
Our manufacturing process includes strict dimensional inspection (OD/ID tolerances), surface quality checks and optional annealing or passivation to meet specific end-use requirements. We offer common needle sizes from ultra-fine medical or instrumentation tubes up to larger diameters for industrial sensors — and we can supply coils, spools or straight cut-to-length pieces with customer-specified end finishes.
| Parameter | Typical Value / Notes |
