Product Description

S355JR Steel (1.0045 Material) Properties & Equivalent

EN10025 S355JR Steel (1.0045 Material)

S355JR steel (1.0045 material) is one of the quality grades in S355 steel group, the steel has a minimum yield strength of 355 MPa (51 ksi) when the thickness is ≤16mm, and the minimum impact energy 27J at room temperature 20 °C (68 °F). The S355 steel group also includes other quality grades such as: S355J0, S355J2 and S355K2.

S355JR Material Properties

S355JR material properties are listed in the datasheet below, including chemical composition, physical and mechanical properties, etc.

Chemical Composition

Chemical composition based on heat analysis.

Chemical Composition, % (≤)
Standard	Steel (Material Number)	C	Si	Mn	P	S	Cu	N	Method of deoxidation
EN 10025-2	S355JR (1.0045)	0.24	0.55	1.60	0.035	0.035	0.55	0.012	Rimming steels not allowed

 

Chemical Composition (Product Analysis), % (≤)
Standard	Steel (Material Number)	C	Si	Mn	P	S	Cu	N	Method of deoxidation
EN 10025-2	S355JR (1.0045)	0.27	0.60	1.70	0.045	0.045	0.60	0.014	Rimming steels not allowed

Note:

• For carbon content (C) and nominal thickness (t), C by agreement when sections with nominal thickness > 100 mm.
• For long products the P and S content can be 0.005 % higher.
• If the chemical composition shows a total aluminum (Al) content of ≤0.020% or acid-soluble Al ≤ 0.015%, or if sufficient other nitrogen-binding elements are present, the N maximum does not apply. In this case, the nitrogen-binding element should be mentioned in the inspection document.
