General information about 08Cr18T1 steel
| The substitute for the following steel grades |
| To substitute for steel grade: 12Х17, 08Х17Т. |
| Delivery type |
| GOST 5582−75 thin sheet. |
| Application |
| Welded structures not exposed to impact loads and working mainly in oxidizing environments, such as nitric acid solutions. application in welded structures is mainly limited to small cross-sections of cases (up to 3.0 mm). It is not recommended for use in welded structures operating under shock loads. Limit temperature of welded structures is not lower than -20°C. Steel is heat and corrosion resistant of ferritic class. |

Technological properties of 08Cr18Ti1 steel
| Forging temperature |
| The beginning 950−1050, the end 720−800. Cooling is done in the air. |
| Weldability |
| limited. Satisfactory mechanical properties can be obtained when welding products with small thicknesses up to 2−3 mm. Sv-08H20N9G7T and Sv-05H25N12TU wires are used for automatic submerged-arc welding under flux AN-26 and ANF-14. Steel is successfully welded by argon-arc welding without filler material and with 10X18H10T steel wire as a filler material. Contact welding is used for small sections. |
