316L Stainless Steel Wire – Condensed Summary

Based solely on the provided tables and text. No data or applications have been added.

General

Austenitic (low-carbon) grade, low-carbon version of 316.
Combines 316's corrosion resistance with excellent weldability – no intergranular corrosion concerns after welding.
Contains Mo (2.0–3.0%) for enhanced pitting/crevice corrosion resistance, especially in chloride environments (e.g., seawater).

Chemical Composition (wt%) – from tables

Element	C	Si	Mn	P	S	Ni	Cr	Mo
316L	≤0.03	≤1.0	≤2.0	≤0.04	≤0.03	12–15	16–18	2.0–3.0

(Other grades – 304, 304L, 316, 310S, 2205 – are listed for reference in the comparison table.)

Fine Wire Diameter Range (from table – general, not grade-specific)

Diameter (mm)	Tolerance (mm)	Max Ovality (mm)
0.020–0.049	+0.002 / −0.001	0.001
0.050–0.074	±0.002	0.002
0.075–0.089	±0.002	0.002
0.090–0.109	+0.003 / −0.002	0.002

Core Characteristics (from grade comparison table)

Low-carbon 316.
Excellent weldability, no need for post-weld heat treatment.
Suitable for chemical equipment with high welding requirements, nuclear industry, coastal construction, and medical devices.

Typical Applications (condensed from the detailed list, grouped by sector)

Marine & Offshore – reverse osmosis pressure vessels, high-pressure seawater piping, offshore platform process lines, subsea manifolds/jumpers, LNG carrier containment systems, offshore wind cooling/firefighting pipes.
Chemical & Process – large field-welded towers/reactors (e.g., urea synthesis, acetic acid) without post-weld heat treatment; high-purity media systems (semiconductor, pharma); heat exchangers (plate, spiral, shell-and-tube); pulp bleaching towers; FGD absorber bodies and spray layers.
Medical & Bioengineering – surgical implants (bone plates, screws, intramedullary nails, spinal rods), sutures, vascular stents, guidewires, catheter braids, microsurgical instruments, dental files, medical equipment frames.
Food & Hygienic – CIP and aseptic transfer piping, storage tanks, food processing platforms, fermentation vessels, UHT heat exchangers.
Nuclear & Specialized – auxiliary systems (cooling water, chemical/volume control) outside the nuclear island; fuel reprocessing equipment; fusion device cooling components.
Automotive & Transport – exhaust flexible joints, EGR cooler housings, sensor housings, EV battery cooling connectors, rail transit brake piping and toilet modules.
Construction & Decoration – coastal curtain wall supports, bridge railings, large outdoor sculptures, swimming pool/fountain piping.
Textiles & Protective – anti-static conductive fibres (drawn micro-wires), high-precision filter media with welded borders.
Precision Manufacturing – welded bellows, micro-springs, vacuum chambers and flanges.
Raw Materials & Emerging – welding consumables (TIG/MIG filler for 316/316L), metal 3D printing feedstock, hydrogen station piping and storage vessels.
