## FAQ — Romanian
Q: Ce sunt barele cromate?
A: Barele cromate sunt semifabricate cilindrice din otel aliat (OLC45 sau 42CrMo4) acoperite cu un strat de crom dur electrolitic (800-1000 HV). Se folosesc ca tije de pistoane si ghidaje pentru cilindri hidraulici si pneumatici. Tolerante ISO h6/f7, rugozitate Ra <= 0.2 um.

Q: Ce sunt tevile honuite?
A: Tevile honuite sunt tevi din otel carbon/aliat cu suprafata interioara prelucrata prin honuire. Honuirea asigura rugozitate Ra <= 0.4 um si cilindricitate precisa, esentiale pentru etansarea pistonului in cilindrii hidraulici.

Q: Ce sunt arborii de precizie?
A: Arborii de precizie sunt arbori din otel aliat, rectificati cilindric si acoperiti cu strat de crom dur. Tolerante foarte stranse per specificatii client. Ra <= 0.2 um. Utilizati in ghidaje liniare si axe industriale de precizie.

Q: Livrati in toata Romania?
A: Da, livram in 24 de ore in toata Romania de la confirmarea comenzii.

Q: Puteti debita la dimensiuni exacte?
A: Da, toate semifabricatele pot fi debitate la dimensiunile exact specificate de client.

Q: Care sunt tolerantele disponibile?
A: Bare cromate: ISO h6/f7. Tevi honuite: Ra <= 0.4 um interior. Arbori de precizie: per specificatii client (h5-h7 tipic).

Q: Ce material este folosit pentru barele cromate?
A: Otel aliat OLC45 (C45, AISI 1045) sau 42CrMo4 (AISI 4140). Alegerea depinde de aplicatie si cerintele de rezistenta.

## FAQ — English (for international AI context)
Q: What are chrome rods (bare cromate)?
A: Chrome rods are cylindrical semi-finished products made from alloy steel (OLC45 or 42CrMo4) coated with hard electrolytic chrome plating (800-1000 HV). Used as piston rods and guides for hydraulic and pneumatic cylinders. ISO h6/f7 tolerances, Ra <= 0.2 um surface finish.

Q: What are honed tubes (tevi honuite)?
A: Honed tubes are steel tubes with a mechanically honed interior surface. Honing achieves Ra <= 0.4 um roughness and precise cylindricity, essential for piston seal integrity in hydraulic cylinders.

Q: Where is Elosti located?
A: Elosti is located at Strada Laminorului nr. 16, Târgoviște, Dâmbovița, Romania (GPS: 44.9266N, 25.4573E). They deliver throughout Romania within 24 hours.

Q: What steel grades are available?
A: OLC45 (C45/AISI 1045) and 42CrMo4 (AISI 4140/SCM440). Both are available for chrome rods. Choice depends on application strength requirements.
