Working with E219-15
Is E219 easy to machine?
Deposit is tough and rapidly work-hardening — use rigid setups, sharp positive-rake carbide, heavy positive feed and flood coolant; grinding is often easier than milling.
Can E219 be welded?
SMAW with short arc, DCEP (or AC for -16/-17), interpass ≤150 °C, no preheat needed; redry electrodes 250–300 °C to avoid nitrogen/hydrogen porosity.
Can E219 be formed, bent or molded?
Not a wrought product — weld beads can be peened or lightly dressed, but the high-N austenite work-hardens fast under cold forming.
What surface finishes work on E219?
Grind flush, then pickle-passivate or electropolish; do not use carbon-steel brushes or grinding media to avoid iron contamination and rust staining.

E219-15 — frequently asked
What is E219-15 used for?
E219-15 is typically used for high-strength stainless structures, cryogenic tankage and armor and pressure vessels. In short: high-Mn austenitic electrode; cryogenic to 760 °C service; higher strength than 308L.
What is the yield strength of E219-15?
E219-15 has a typical yield strength of 470 MPa (68.2 ksi) and a tensile strength of 690 MPa (100 ksi) — stronger than 74% of stainless steel grades. Strength varies by condition: see the 6 listed tempers.
Is E219-15 easy to machine?
Not especially — machinability is rated poor (24/100, worse than 93% of stainless steel grades). Deposit is tough and rapidly work-hardening — use rigid setups, sharp positive-rake carbide, heavy positive feed and flood coolant; grinding is often easier than milling.
Can E219-15 be welded?
Yes — weldability is rated very good (80/100). SMAW with short arc, DCEP (or AC for -16/-17), interpass ≤150 °C, no preheat needed; redry electrodes 250–300 °C to avoid nitrogen/hydrogen porosity.
What surface finishes work on E219-15?
Grind flush, then pickle-passivate or electropolish; do not use carbon-steel brushes or grinding media to avoid iron contamination and rust staining.
Can E219-15 be formed, bent or molded?
Not a wrought product — weld beads can be peened or lightly dressed, but the high-N austenite work-hardens fast under cold forming.
What is the maximum service temperature of E219-15?
E219-15 is rated for continuous use to about 760°C (1,400 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between E219-AW and E219-SA?
AW is the default condition — default condition: properties of the all-weld-metal deposit in the as-deposited state, no PWHT. SA: rare post-weld condition used when the whole fabrication is solution annealed; softens and homogenises the deposit, raising ductility and lowering strength. Yield strength is 460 MPa in AW versus 380 MPa in SA.
