What material is S355K2(+N) / 1.0595?
S355K2 is a medium tensile, low carbon manganese steel which is readily weldable and possess good impact resistance (also in sub-zero temperatures). This material is commonly supplied in the untreated or normalized condition. Machinability of this material is similar to that of mild steel.
What is S355k2 equivalent to?
Q355E
ASTM A709, Australian AS/NZS 3678: Grade 350 L20, and Chinese GB/T 1591: Q355E can also be considered as equivalents to S355K2.

What is the difference between S355J2 and S355K2?
It mainly lies in their impact test: J2 symbol Charpy V-Notch Impact Tested Longitudinal 27 Joules at -20 ˚C under 150mm thickness. K2 symbol Charpy V-Notch Impact Tested Longitudinal 40 Joules at -20 ˚C max 100mm thickness.
What is K2 in S355K2?
Hot-rolled structural steel. The letter S (S = Structural), followed by a number which indicates the yield strength (in this case 355). K2 indicates the minimum impactstrength of 40 Joules (J) at a test temperature of -20°C. N indicates a normalized rolling condition.
What is the yield strength of S355K2?
355 MPa
Grade S355K2 has a minimum yield strength of 355 MPa. The impact energy at a test temperature of -20°C is at least 40 joules.
What is the impact test for S355K2 N?
S355K2+N steel plate Charpy V-Notch Impact Tested Longitudinal 40 Joules at -20 ˚C, S355J2+N steel plate Charpy V-Notch Impact Tested Longitudinal 27 Joules at -20 ˚C under 150mm thickness. S355K2+N steel plate is good in highly impact under low temperature condition projects.
s355k2 vs s355j2
The primary difference between S355J2 and S355K2 structural steel grades lies in their impact energy requirements at -20°C. Both have a minimum yield strength of 355 MPa and similar compositions, but S355J2 requires a minimum impact energy of 27 Joules, while S355K2 requires 40 Joules at the same temperature.
S355J2:
This grade specifies a Charpy V-notch impact test at -20°C with a minimum energy absorption of 27 Joules.
S355K2:
This grade also has a Charpy V-notch impact test at -20°C, but with a higher minimum energy absorption requirement of 40 Joules.
