1.0577 Structural steel
Designation
| DIN: | S 355 J2 (St 52-3) |
| AFNOR: | A 52 FP |
| UNI: | - |
| AISI: | A738 |
Chemical composition:
| C | ≤ 0.22 |
| Si | ≤ 0.55 |
| Mn | ≤ 1.60 |
Strength:
132 - 185 HB
(≈ 450 - 630 N/mm²)
Thermal conductivity at 20 °C:
40 W/m K
Character:
unalloyed structural steel with good weldability
Application:
for common applications in die, mould, and jigs and fixtures construction
Treatment by
Welding:
very good weldability due to its low carbon content
not usual:
Polishing, etching, EDM, nitriding, hard chroming
Heat treatment:
Soft annealing:
650 to 700 °C for about 2 to 5 hours
slow controlled cooling of 10 to 20 °C per hour to about 600 °C;
further cooling in air, max. 180 HB
Technical tip
- If no welding is required, we recommend 1.1730 ⇒ better machinability in spite of higher strength
