Buy surfacing wire by self-delivery or with delivery in Ukraine.
Surfacing wire 30HGSA is used for:
- mechanized arc surfacing
- surfacing of rolls of rolling mills,
- surfacing of railway wheels, bandages
- surfacing of crane and metallurgical equipment in order to increase wear resistance.
General technical requirements
Diameters of welding wire 30KhGSA: 3.0 mm - 4.0 mm - 5.0 mm
Steel wire for surfacing must be manufactured in accordance with the requirements of GOST 10543-98 .
On the surface of the wire 30HGSA, rust, captivity, flaws, whiskers and scale are not allowed. Scale is allowed on the surface of hot-rolled wire 30KhGSA. The surface of cold-drawn wire 30KhGSA should be: clean and smooth - for surfacing wire 30KhGSA without heat treatment, oxidized - for heat-treated NP 30KhGSA.
Traces of soap grease (without graphite, sulfur) on the surface of NP 30KhGSA wires are allowed for all steel grades, except for high-alloy ones.
Cold-drawn wire 30KhGSA is produced without heat treatment or heat-treated, and high-alloyed 30KhGSA - with an etched surface.
Surfacing wire 30KhGSA should be wound into coils or wound on coils or drums in even rows, excluding its fluffing or unwinding. The ends of the wire should be easy to find.
Chemical composition of wire NP 30HGSA:
| Mass fraction of chemical elements, within or not more than% | |||||||||||
| C | Mn | Si | Cr | Ni | Cu | S | P | Mo | As | Al | N |
| 0.25- 0.35 | 0.8- 1.2 | 0.8- 1.2 | 0.8- 1.2 | 0.4 | - | 0.01 | 0.015 | - | - | - | - |
Each coil, coil, drum must consist of one piece of wire NP 30HGSA.
Butt welding of wire of one heat and one diameter is allowed, while the wire at the welding points must comply with the requirements of this standard.
