FAQ About SAE 1005 Baustahl
1. Can SAE 1005 be used for outdoor construction?
Yes—but it needs a coating (Galvanisierung oder Farbe). Ohne Beschichtung, it will rust in 1–2 years in wet climates. We recommend galvanized SAE 1005 for outdoor parts like garage frames—it lasts 15+ Jahre.
2. Is SAE 1005 strong enough for machine shafts?
Only for small, low-stress shafts (Z.B., in blenders or toys). For heavy machinery shafts (Z.B., in tractors), use stronger steel like SAE 1045—SAE 1005 will bend under high loads.
3. Can SAE 1005 ohne Vorheizen geschweißt werden?
Yes—for thin sections (bis zu 6 mm dick). Für dickere Teile (6–12 mm), Vorheizen auf 100–150 ° C, um Risse zu vermeiden. We suggest using MIG welding for SAE 1005—it’s fast and produces strong joints.
