Compare all 4 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
As-welded + stress relief / solution anneal | Only for components solution annealed after welding — dissolves delta ferrite and carbides, softening the deposit and making it essentially non-magnetic. | 300 | 520 | 45 | 150 HB | 2.3 % IACS |
As-welded, all-position with Ar-CO₂ mixed gas | Same wire classified/qualified with 75–80 % Ar / bal CO₂ — lower spatter and fume, marginally lower carbon pick-up and slightly better toughness and ductility. | 415 | 555 | 39 | 178 HB | 2.3 % IACS |
AW-T1-1Default As-welded, all-position | Default all-position rutile flux-cored wire run under 100 % CO₂ — the most widely stocked configuration for shop and site FCAW of 316L. | 420 | 560 | 37 | 180 HB | 2.3 % IACS |
As-welded, flat/horizontal only | Higher-deposition flat-and-horizontal-only version of the same 316L flux-cored wire, chosen for long shop fillets and plate welding. | 430 | 570 | 35 | 185 HB | 2.3 % IACS |
What is E316LT-1?
E316LT-1 (UNS W31613, E316LT1-1) is a rutile flux-cored tubular wire depositing molybdenum-bearing 316L-type austenitic weld metal, available in T1-1 (CO₂), T1-4 (Ar/CO₂) and T0-1 flat-position versions. It is used for high-productivity FCAW of 316 and 316L chemical and marine equipment, with deposits about 420 MPa yield, 560 MPa tensile, 37% elongation, 180 HB (88 HRB) and corrosion resistance rated 76 — the highest of the austenitic flux-cored wires listed here. Maximum service temperature is 400 °C and slag must be removed each pass; E308LT-1 is the lower-cost option when molybdenum is not required. E316LT-1 has a density of 7.98 g/cm³ (0.288 lb/in³), heavier than 85% of stainless steel grades. It melts at 1,385°C (2,525 °F). E316LT-1 has a yield strength of 420 MPa (60.9 ksi) and a tensile strength of 560 MPa (81.2 ksi) — stronger than 64% of stainless steel grades. Elongation at break is 37% and the elastic modulus is 193 GPa (28 Msi).

Working with E316LT-1
Is E316LT-1 easy to machine?
Deposit machines like 316L — work-hardens fast; use sharp carbide, positive rake, heavy feed and flood coolant, and remove slag/oxide before cutting.
Can E316LT-1 be welded?
DCEP, 100 % CO₂ (–1) or 75–80 % Ar/CO₂ (–4), 20–30 L/min, 15–25 mm stickout; keep interpass ≤ 150 °C, no preheat, redry damp spools per producer instructions and deslag every pass.
Can E316LT-1 be formed, bent or molded?
Not a formable product form; weld beads may be lightly peened or ground but heavy cold work of the deposit is not recommended.

E316LT-1 — frequently asked
What is E316LT-1 used for?
E316LT-1 is typically used for FCAW welding of 316/316L process equipment, chemical plant piping and tanks, marine and coastal structural fabrication, pulp and paper digesters and vessels, pharmaceutical and brewery process tanks and seawater cooling and effluent handling systems. In short: mo-bearing flux-cored 316L; best corrosion of the T1 austenitics; high-deposition all-position wire.
What is the yield strength of E316LT-1?
E316LT-1 has a typical yield strength of 420 MPa (60.9 ksi) and a tensile strength of 560 MPa (81.2 ksi) — stronger than 64% of stainless steel grades. Strength varies by condition: see the 4 listed tempers.
Is E316LT-1 easy to machine?
Not especially — machinability is rated fair (38/100, better than 63% of stainless steel grades). Deposit machines like 316L — work-hardens fast; use sharp carbide, positive rake, heavy feed and flood coolant, and remove slag/oxide before cutting.
Can E316LT-1 be welded?
Yes — weldability is rated excellent (92/100). DCEP, 100 % CO₂ (–1) or 75–80 % Ar/CO₂ (–4), 20–30 L/min, 15–25 mm stickout; keep interpass ≤ 150 °C, no preheat, redry damp spools per producer instructions and deslag every pass.

What is the maximum service temperature of E316LT-1?
E316LT-1 is rated for continuous use to about 400°C (752 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between E316LT-1 AW-T1-1 and E316LT-1 AW-SR?
AW-T1-1 is the default condition — default all-position rutile flux-cored wire run under 100 % CO₂ — the most widely stocked configuration for shop and site FCAW of 316L. AW-SR: only for components solution annealed after welding — dissolves delta ferrite and carbides, softening the deposit and making it essentially non-magnetic. Yield strength is 420 MPa in AW-T1-1 versus 300 MPa in AW-SR.
How much does E316LT-1 cost?
E316LT-1 is a high-cost stainless steel ($$$$), pricier than about 78% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
