Steel A572 vs EN353
Steel · grade comparison
Steel A572 and EN353 are both steel grades. EN353 is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 360 MPa (52.2 ksi) for A572, about 33% more; tensile strength follows at 760 MPa (110 ksi) vs 480 MPa (69.6 ksi). In exchange, A572 is the more ductile: elongation 22% versus 18% for EN353, and EN353 is harder (229 HB vs 145 HB). A572 runs hotter in service (400°C vs 200°C continuous) and A572 conducts electricity better (9 % IACS vs 7.8 % IACS). On the shop floor, A572 welds better (very good vs fair).
A572Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
EN353Choose it when strength drives the design.
A572 vs EN353: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all steel grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

A572 vs EN353 — frequently asked
Is EN353 stronger than A572?
Yes. EN353 has a typical yield strength of 480 MPa (69.6 ksi) against 360 MPa (52.2 ksi) for A572 — about 33% more. Tensile strength is 760 MPa (110 ksi) vs 480 MPa (69.6 ksi).
Which is cheaper, A572 or EN353?
Both sit in the same relative cost tier ($$, standard); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which welds better, A572 or EN353?
A572. Its weldability rates very good (82/100) against fair (42/100) for EN353.
