| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |

Working with E220
Is E220 easy to machine?
Soft and gummy — use sharp positive-rake tools, high speed and generous coolant to avoid built-up edge and stringy chips; a leaded/resulphurised grade is better for heavy turning.
Can E220 be welded?
Excellent weldability by MAG, TIG, resistance and laser with no preheat at tube wall thicknesses; CEV stays well below 0.4 so no post-weld heat treatment is needed.
Can E220 be formed, bent or molded?
Cold bends to tight radii (typically ≥1.5×D on mandrel), flares, expands and roll-forms readily; anneal (+A) or use +CR2 for the most severe forming.
E220 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

|---|---|---|
| Ccast analysis, EN 10305-3/-5 | ≤ 0.17 | 0.12 |
| Siwhere specified | ≤ 0.35 | 0.15 |

What surface finishes work on E220?
No anodizing — protect with zinc/zinc-nickel plating, phosphate + oil, blackening, e-coat or powder paint; surfaces take a fine ground/polished finish but corrode rapidly if left bare.
Surface treatments FabDigit runs on steel parts — pick them in the quote configurator or call them out on the drawing. Each links to its datasheet in the surface-finish library (thickness, specs, call-out, material verdicts).

E220 — frequently asked
What is E220 used for?
E220 is typically used for precision steel tubing, hydraulic/pneumatic lines, machine frame tubes and furniture tubing. In short: EN 10305 precision tube grade; weldable and tight-bending; low strength, no corrosion resistance.
What is the yield strength of E220?
E220 has a typical yield strength of 250 MPa (36.3 ksi) and a tensile strength of 360 MPa (52.2 ksi) — weaker than 94% of steel grades. Strength varies by condition: see the 4 listed tempers.
Is E220 easy to machine?
Reasonably — machinability is rated good (58/100, better than 75% of steel grades). Soft and gummy — use sharp positive-rake tools, high speed and generous coolant to avoid built-up edge and stringy chips; a leaded/resulphurised grade is better for heavy turning.
Can E220 be welded?
Yes — weldability is rated excellent (95/100). Excellent weldability by MAG, TIG, resistance and laser with no preheat at tube wall thicknesses; CEV stays well below 0.4 so no post-weld heat treatment is needed.
What surface finishes work on E220?
No anodizing — protect with zinc/zinc-nickel plating, phosphate + oil, blackening, e-coat or powder paint; surfaces take a fine ground/polished finish but corrode rapidly if left bare.

Cold bends to tight radii (typically ≥1.5×D on mandrel), flares, expands and roll-forms readily; anneal (+A) or use +CR2 for the most severe forming.
What is the maximum service temperature of E220?
E220 is rated for continuous use to about 350°C (662 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
How much does E220 cost?
E220 is a budget-cost steel ($), cheaper than about 90% 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.
