S355 S355JR Steel Angle Iron

S355

S - stands for structural steel

355 - stands for minimum yield strength 

Normally S355 will have following variation based on impact strength at different temperatures, as steel become more brittle when temperature drops. If your structure need to withstand -20°C, it's better and safer to choose S355J2.

S355JR - Can withstand an impact energy of 27J at +20°C

S355J0 - Can withstand an impact energy of 27J at 0°C

S355J2 - Can withstand an impact energy of 27J at -20°C

S355K2 - Can withstand an impact energy of 27J at -30°C (40J at -20°C)

S355 Yield Strength

S355 is named based on it's minimum yield strength of 355 Mpa (N/mm2), However the yield strength reduces when you go up in thickness above 16 mm for flat products & hollow sections
Here is the table showing reduction in yield strength based on thickness
Up to 16 mm - 355 Mpa
16 mm < t ≤ 40 mm - 345 Mpa
40 mm < t ≤ 63 mm - 335 Mpa
63 mm < t ≤ 80 mm - 325 Mpa
80 mm < t ≤ 100 mm - 315 Mpa
100 mm < t ≤ 150 mm - 295 Mpa

Our factory has complete production facilities, and provides laser cutting , bending, welding, painting, assembly and other processing services.

We have own large-scale indoor warehouse with perennial spot stocks totally above 5000 tons mainly include 2000 tons galvanized

steel series and 2500 tons carbon steel series

All the products have to pass the inspections such as tension test, hardness test, spectrophotometer test, salt spray test and PH

test before leaving the factory .
