Working with FeCr-LC C0.06

Is FeCr-LC easy to machine?

Not machinable — hard, brittle carbide-bearing ferroalloy supplied crushed and screened; size reduction is by jaw crusher and screening, not cutting.

Can FeCr-LC be welded?

Not a weldable product form; it is dissolved as an alloying addition in EAF/AOD/ladle melts (also used in cored wire and hardfacing electrode coatings).

Can FeCr-LC be formed, bent or molded?

No cold or hot forming; cast into chills, crushed to 10–50 mm or 50–100 mm, with fines briquetted for ladle trimming.

What surface finishes work on FeCr-LC?

No surface finishing applies; keep lump dry and covered to avoid rusting of fines and to control moisture-related hydrogen pickup in the melt.

FeCr-LC C0.06 — frequently asked

What is FeCr-LC C0.06 used for?

FeCr-LC C0.06 is typically used for low-carbon stainless steel production, precision alloy steel making and vacuum induction melting charge. In short: low-carbon chromium addition; graded C0.03 to C0.50; highest-melting ferrochrome grade.

What is the tensile strength of FeCr-LC C0.06?

FeCr-LC C0.06 has a typical tensile strength of 265 MPa (38.4 ksi) — weaker than 87% of refractory metal grades. Strength varies by condition: see the 6 listed tempers.

Is FeCr-LC C0.06 easy to machine?

Not especially — machinability is rated not recommended (6/100, worse than 94% of refractory metal grades). Not machinable — hard, brittle carbide-bearing ferroalloy supplied crushed and screened; size reduction is by jaw crusher and screening, not cutting.

Can FeCr-LC C0.06 be welded?

Not readily — weldability is rated not recommended (8/100). Not a weldable product form; it is dissolved as an alloying addition in EAF/AOD/ladle melts (also used in cored wire and hardfacing electrode coatings).

What surface finishes work on FeCr-LC C0.06?

No surface finishing applies; keep lump dry and covered to avoid rusting of fines and to control moisture-related hydrogen pickup in the melt.

Can FeCr-LC C0.06 be formed, bent or molded?

No cold or hot forming; cast into chills, crushed to 10–50 mm or 50–100 mm, with fines briquetted for ladle trimming.

What is the maximum service temperature of FeCr-LC C0.06?

FeCr-LC C0.06 is rated for continuous use to about 850°C (1,562 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
