Technological properties of the material S345 ( S345, С345 ) .
Weldability:
without limitations.
Specification :
Mechanical properties :
sв
- Tensile strength , [MPa]
sT
- Yield stress, [MPa]
d5
- Specific elongation at fracture , [ % ]
y
- Reduction of area , [ % ]
KCU
- Impact strength , [ kJ / m2]
HB

Weldability :
without limitations
- welding is done without heating and subsequent heat treeting
limited weldability
- welding is possible under heating up to 100-120 grade and subsequent heat treeting
hard weldability
- obtaining the quality welding needs the additional operations:heating up to 200-300 grade; the heat treeting ia annealing
