Product information for purchasing teams
SS 316L is the low-carbon version of 316 and the most requested molybdenum stainless. Carbon at or below 0.030% keeps welds free of sensitisation, which is why it is specified for welded process piping, pharmaceutical and food plant, and chemical tanks.
Exact specification, availability and commercial details are confirmed against your enquiry.

Questions buyers ask
What is the difference between 316 and 316L?
The L grade limits carbon to 0.030% against 0.08% for 316. It welds without sensitisation, so it is preferred for welded construction. Dual-certified 316/316L material meets both specifications.
Which standard covers SS 316L Tubes?
SS 316L Tubes are supplied to ASTM A213 / A269 TP316L.
What sizes of SS 316L Tubes does Steel Impex India supply?
Outside diameter: 6 mm to 101.6 mm (1/4" to 4"); other sizes on enquiry. Wall thickness: 0.5 mm to 5 mm, or BWG gauge. Exact availability is confirmed for each enquiry.
Do SS 316L Tubes come with a mill test certificate?
Yes. Material is supplied with a mill test certificate to EN 10204 3.1, traceable to the heat number. Third-party inspection to 3.2 can be arranged on request.
What should I send for a SS 316L Tubes quotation?
Send OD, wall thickness or BWG, length, straight or U-bent, quantity and certificate type.
Where is Steel Impex India located?
Steel Impex India is at 231/235, Sant Sena Maharaja Marg, 2nd Kumbharwada, Mumbai 400004, and supplies across India.
