Working with E260 +LC

Is E260 easy to machine?

Machines like ordinary low-carbon steel — gummy chips and built-up edge; use sharp positive-rake tools, high speed and generous coolant, or specify a resulfurized grade if heavy turning is planned.

Can E260 be welded?

Excellent weldability by MIG/TIG/resistance/laser with CEV around 0.30; no preheat for typical tube walls, and the cold-worked strength is locally lost in the HAZ.

Can E260 be formed, bent or molded?

Cold bends, flares, expands and end-forms well in the +CR2/+LC conditions; keep bend radii ≥ 2–3 × D in the harder +CR1/+C tempers to avoid seam cracking.

What surface finishes work on E260?

No anodizing; protect with oiling, zinc phosphate, electro/hot-dip zinc, e-coat or powder paint — bare tube rusts within days in humid storage.

E260 +LC — frequently asked

What is E260 +LC used for?

E260 +LC is typically used for precision steel tubing, cylinder tubes, structural tube components and automotive tubing. In short: mid-strength precision tube steel; weldable cold-sized tube; stronger than E220.

What is the yield strength of E260 +LC?

E260 +LC has a typical yield strength of 275 MPa (39.9 ksi) and a tensile strength of 380 MPa (55.1 ksi) — weaker than 91% of steel grades. Strength varies by condition: see the 3 listed tempers.

Is E260 +LC easy to machine?

Reasonably — machinability is rated good (60/100, better than 83% of steel grades). Machines like ordinary low-carbon steel — gummy chips and built-up edge; use sharp positive-rake tools, high speed and generous coolant, or specify a resulfurized grade if heavy turning is planned.

Can E260 +LC be welded?

Yes — weldability is rated excellent (95/100). Excellent weldability by MIG/TIG/resistance/laser with CEV around 0.30; no preheat for typical tube walls, and the cold-worked strength is locally lost in the HAZ.

What surface finishes work on E260 +LC?

No anodizing; protect with oiling, zinc phosphate, electro/hot-dip zinc, e-coat or powder paint — bare tube rusts within days in humid storage.

Can E260 +LC be formed, bent or molded?

Cold bends, flares, expands and end-forms well in the +CR2/+LC conditions; keep bend radii ≥ 2–3 × D in the harder +CR1/+C tempers to avoid seam cracking.

What is the maximum service temperature of E260 +LC?

E260 +LC 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.
