Stainless Steel Reinforcement Bars
Elongation:
Aj = 100 mm marked before tension measured after tension to fracture measuring point 2.5 x diameter from fracture.
A10 = Diameter x 10 marked before tension measured after tension to frature measured across fracture.
Choice of Reinforcing :
The grade of reinforcement steel will depend upon type of corrosive atmosphere
| For moderate atmosphere high yield reinforcement steel like 1.4301 (304) can be used. |
| For more severe corrosive atmospheres 1.4401 (316), 1.4429 (316LN), 1.4436 (316) & 1.457 ( 316Ti) can be used. |
| For high aggressive atmospheres duplex steel 1.4362, 1.4462 (2205) is recommended. |
