Steel EN353 vs EN41B

Steel · grade comparison

Steel EN353 and EN41B are both steel grades. EN41B is the stronger of the two: yield strength 740 MPa (107 ksi) against 480 MPa (69.6 ksi) for EN353, about 54% more; tensile strength follows at 925 MPa (134 ksi) vs 760 MPa (110 ksi). In exchange, EN353 is the more ductile: elongation 18% versus 15% for EN41B, and EN41B is harder (269 HB vs 229 HB). EN41B runs hotter in service (450°C vs 200°C continuous). On the shop floor, EN353 welds better (fair vs poor).

EN353Choose it when the part is bent, formed or impact-loaded, or when it will be welded.

EN41BChoose it when strength drives the design, or when the part sees heat.

EN353 vs EN41B — frequently asked

Is EN41B stronger than EN353?

Yes. EN41B has a typical yield strength of 740 MPa (107 ksi) against 480 MPa (69.6 ksi) for EN353 — about 54% more. Tensile strength is 925 MPa (134 ksi) vs 760 MPa (110 ksi).

Which is cheaper, EN353 or EN41B?

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 is easier to machine, EN353 or EN41B?

EN353. Its machinability rates good (55/100) against fair (50/100) for EN41B; for welding the order is EN353 first (fair, 42/100) then EN41B (poor, 20/100).
