# S355 J2G3 STEEL EQUIVALENCE

## S355 J2G3 STEEL EQUIVALENCE

(OP)

Hello friends,

Can you please tell me which is the equivalence on ASTM of S355 J2 G3 steel??

I found a link which sayed it is A575 GR50. Is it correct?

Thanks for a fast fact check!!

### RE: S355 J2G3 STEEL EQUIVALENCE

I think you will find that S355J2G3 is an old designation (EN10025:1990) which was replaced in 2004 with S355J0. If you want an equivalent then it has a yield of 355MPa and guaranteed impact properties (Charpy test) of 27 Joules at zero degrees Celsius.

An ASTM equivalent would be A572 Grade 50 which has a yield of 345 MPa but you would need to invoke supplementary clause S5, and state requirements, to get the impact properties.

### RE: S355 J2G3 STEEL EQUIVALENCE

The J2 means 27J @ -20°C, J0 means 27J @ 0°C. Couldn't immediately find the meaning of G3, have to search in my old standards.
Yield = 355MPa, the S stands for Structural steel.
Correct that the J2 has been replaced with J0, however I'd still search for something with 27J @ -20°C, just to be sure... Can't be too hard.

### RE: S355 J2G3 STEEL EQUIVALENCE

S355J2G3 was defined in EN 10025:1990.
J2 : a minimum Impact Energy of 27 J at -20°C (Charpy-V-specimen in longitudinal direction, average of 3 values)
G3 : the delivery condition is normalized for flat products (plates, coils, sheets). For Long products (sections, bars,..) the delivery condition is at the discretion of the manufacturer unless otherwise agreed.
In EN 10025-2:2004 S355J2G3 was replaced either by S355J2+N for flat products or by S355J2 for long products.

Thanks friends, great info.

I will make sure to test impact properties from the material I will use to replace S355...

White Paper - Addressing Tooling and Casting Requirements at the Design Stage
Several of the tooling and casting requirements of a part can be addressed at the design stage. If these requirements are not addressed at the design stage, lot of time is spent in design iteration when the design reaches the die caster. These design issues lead to increase in time and cost of production leading to delay in time to market and reduced profits for the organization. Download Now
White Paper - The Other Side of Design for Assembly
Assembly level constraints need to be satisfied before the design can move downstream. This white paper will go through the various assembly level issues, which need to be tackled by various organizations on a regular basis. Know more about DFMPro, a design for assembly software. Download Now
