Field of application
Sv-07Cr25Ni13 (07Cr25Ni13-e) welding wire is used for welding critical equipment on the basis of heat-resistant steels: 20Cr25Ni13, 20Cr25Ni18 and similar types, which are operated at temperatures up to 1000 °C in oxidizing gas environments. This welding wire perfectly welds 25X25H20C2, 15X25T steel grades as well as low-alloy carbon steel grades with austenitic high-alloy grades. Such wire is used for welding details of bilayer steels alloyed with 12X18N9T or 12X18N10T layer or anticorrosive pearlitic steels coating. Cladding of intermediate layer on the parts is performed.
Production
Sv-07Cr25Ni13 welding wire is manufactured in accordance with RD 03-613-03,
Percentage composition according to (GOST 2246-70)
| C | Si | Mn | Ni | S | P | Cr | N |
| ≤ 0.09 | 0.5 - 1 | 1 - 2 | 12 - 14 | ≤ 0.018 | ≤ 0.025 | 23 - 26 | up to 0.05 |
The wire for surfacing has a Cr content of at least 23.5%. The tensile strength of high-alloyed and alloyed wire as per the standards is given below.
