Typical Automotive Grades

SAE 1019, 1518, 1035, 1040, SAE 4130H, SAE 4140H, SAE 8620, 20 Mn Cr5, 16NiCr4 and ST-62-N. Other steel grades may also be used on specific request.

Specification

Standard specifications that we manufacture include BS980, DIN 2391, BS 1717, IS 1601, IS 1074, JIS Gr.6, STK 45. In addition we also manufacture to customized specification depending on the requirements of a particular customer.

Standard Packing

Each tube is oiled, internally as well as externally, and then packed into hexagonal bundles. This ensures that the tubes are corrosion protected and that they retain their straightness during transport. Upon request we can provide end caps and also wrap the bundles in LDPE sheets.

Lengths

Tubes are generally supplied in random lengths of 4 to 7 meters (or in a different range as per customer specifications). Tubes in exact lengths, multiples of specified unit lengths or in long lengths can also be supplied.

Testing And Inspection

All our tubes are tested as per customer requirements. Our testing facilities include full-body Ultrasonic, Eddy Current, Leakage-Flux and Hydro-testing.
