What is the equivalent of S355J0 steel?

S355J0 is a European standard structural steel grade specified in EN 10025-2.

S355JO is a medium tensile, low carbon manganese steel which is readily weldable and possess good impact resistance. This material is commonly supplied in the untreated or normalized condition.

1. ASTM (American Standards):

ASTM A572 Grade 50: This is a common equivalent to S355J0 in terms of mechanical properties and usage in construction and structural applications.

ASTM A36: While A36 has lower mechanical properties than S355J0, it can sometimes be used as an equivalent in less demanding applications.

2. DIN (German Standards):

DIN 17100 St52-3: This is an older standard that corresponds to S355J0, although S355J0 offers better notch toughness due to its "J0" designation.

DIN EN 10025-2 S355JR: This is the German equivalent under the same EN standard but with slightly different impact energy requirements (S355JR is tested at 20°C, while S355J0 is tested at 0°C).

3. JIS (Japanese Standards):

JIS G3106 SM490: This is a Japanese equivalent to S355J0 in terms of mechanical properties.

4. Chinese Standards:

GB/T 1591 Q345B: This is a common Chinese equivalent to S355J0, with similar strength and mechanical properties.

5. Indian Standards:

IS 2062 E350: This is an Indian standard equivalent to S355J0, typically used in structural applications.

6. Other European Standards:

EN 10025-2 S355J2: S355J2 is similar to S355J0 but with a higher impact energy test temperature (-20°C instead of 0°C). It is often used as an equivalent in applications requiring better toughness.

Summary:

S355J0 is equivalent to several international steel grades such as ASTM A572 Grade 50, DIN St52-3, JIS SM490, and GB/T Q345B, depending on the specific requirements of the application and regional standards.
