Details of the exhaust system of cars, bargaining. equipment. It is permitted as a container and equipment for the food industry with a period of contact of products with a surface of not more than 24 hours. Recommended argon-arc welding, filler wire 10X18H10T
design, not exposed to shock loads and working mainly in oxidizing environments. The use of welded structures is largely limited to small sections of the parts (up to 3.0 mm). Not recommended for welded structures operating under shock loads. The limiting service temperature weldments not below -20 ° C .; ferritic steel grade

Description |
| no limits |
|
Welding is performed without heating and without subsequent heat treatment |
| Boundedly welded |
|
Welding is possible with heating up to 100–120 °C and subsequent heat treatment |
| Difficult to weld |
|
For obtaining quality welded joints, additional operations are required: heating up to 200–300 °C for welding, heat treatment after welding — annealing |
| Not applicable for welded structures |
