What is the density of S275JR?

7850 kg/m³ — the figure the weight calculators on this site use for S275JR. The value is ArcelorMittal / ASTM & EN standard references’s.

What are the mechanical properties of S275JR?

Tensile 410–560 MPa, Yield ≥ 275 MPa, Elongation min ≥ 23 % — EN 10025-2, Plate/Sections, As rolled. Those are the standard’s requirements; the mill test certificate governs the metal delivered.

What is S275JR equivalent to?

ASTM A36. Equivalents are approximate, never identical — compare the certificate against your specification before substituting.

Each row is one standard, one product form and one condition — the values do not transfer across rows. A blank cell means the standard sets no requirement.

Reference values from the cited standards. They describe what the standard requires, not a specific heat of material; the mill test certificate governs what is delivered.

Approximate equivalents

Approximate equivalents: equivalents are a technical reference, not a substitution instruction, verify against project specification.

Approximate equivalents
Grade	Systems	Relationship	Note	Key difference
ASTM A36	ASTM → EN	Near comparable	Often compared for general structural use, but not an automatic equivalent.	Yield/chemistry/impact and dimensional standards differ. Project approval required. Compared designation: S275JR.
