What Is Low Carbon Steel Wire Rod?
Low Carbon Steel Wire Rod, denoted as SWRM (Steel Wire Rod Mild), contains approximately 0.12 to 0.30% carbon and has a tensile strength of less than 490. There are eight types, ranging from SWRM6 to SWRM22, based on carbon content.
Uses of Low Carbon Steel Wire Rod
Primarily used for drawing nails and small objects, these wire rods are suitable for products such as nails, rivets, iron wire, barbed wire, galvanized iron wire, welded wire mesh, construction fittings, and small screws. Due to its low carbon content and variation in precision, it is not recommended for precision-required applications or in low-temperature environments.
Characteristics of Low Carbon Steel Wire Rod
Low Carbon Steel Wire Rods are available in eight types, with carbon content ranging from SWRM6 to SWRM22:
- SWRM6: Extra mild steel with carbon content up to 0.08%. Used for ordinary steel wire and nails.
- SWRM8: Extra mild steel with carbon content up to 0.10%. Used for steel wires and nails.
- SWRM10: Carbon content of 0.08-0.13%. Used for hard-drawn iron wire.
- SWRM12: Carbon content of 0.10-0.15%.
- SWRM15: Carbon content of 0.13-0.18%.
- SWRM17: Carbon content of 0.15-0.20%. Mild to semi-mild steel.
- SWRM20: Carbon content of 0.18-0.23%. Semi-mild steel.
- SWRM22: Carbon content of 0.20-0.25%. Highest hardness and tensile strength among Low Carbon Steel Wire Rods.
These wire rods are used in various applications due to their versatility and range of mechanical properties.
