Working with E316-17
Is E316 easy to machine?
Deposit machines like 316 — low speeds, positive rake, rigid setup and flood coolant to avoid work hardening; grind-out of slag inclusions is easier than machining.
Can E316 be welded?
Redry electrodes (basic -15 types 250–300 °C, rutile 120–150 °C), keep interpass below ~150 °C, use stringer beads and short arc; aim for FN 4–10 ferrite to avoid hot cracking, and prefer E316L where as-welded intergranular corrosion matters.
Can E316 be formed, bent or molded?
Not a wrought product; the deposit is tough and ductile enough for hammer-peening and light straightening of weldments but should not be cold formed heavily.
What surface finishes work on E316?
Remove all slag and heat tint, then pickle/passivate per ASTM A967 or electropolish to restore full pitting resistance; do not anodise.

E316-17 — frequently asked
What is E316-17 used for?
E316-17 is typically used for chemical processing equipment, marine fabrication, food and pharmaceutical equipment and pulp and paper equipment. In short: workhorse Mo-bearing electrode; weldability score 92; general 316 fabrication filler.
What is the yield strength of E316-17?
E316-17 has a typical yield strength of 430 MPa (62.4 ksi) and a tensile strength of 570 MPa (82.7 ksi) — stronger than 67% of stainless steel grades. Strength varies by condition: see the 5 listed tempers.
Is E316-17 easy to machine?
Not especially — machinability is rated poor (34/100, worse than 55% of stainless steel grades). Deposit machines like 316 — low speeds, positive rake, rigid setup and flood coolant to avoid work hardening; grind-out of slag inclusions is easier than machining.
Can E316-17 be welded?
Yes — weldability is rated excellent (90/100). Redry electrodes (basic -15 types 250–300 °C, rutile 120–150 °C), keep interpass below ~150 °C, use stringer beads and short arc; aim for FN 4–10 ferrite to avoid hot cracking, and prefer E316L where as-welded intergranular corrosion matters.

Can E316-17 be formed, bent or molded?
Not a wrought product; the deposit is tough and ductile enough for hammer-peening and light straightening of weldments but should not be cold formed heavily.
What is the maximum service temperature of E316-17?
E316-17 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 E316-16 and E316-17?
E316-16 is the default condition — the default stock electrode: smooth AC/DC-capable arc, all-position, good bead appearance for general 316 fabrication. E316-17: pick for the smoothest, most fluid arc and easiest slag release on flat/horizontal fillet work; slightly less suited to vertical-up than -16. Yield strength is 420 MPa in E316-16 versus 430 MPa in E316-17.
