Both S355JR and A572 Grade 50 are carbon structural steel. S355JR is in EN 10025-2 and A572 Grade 50 in ASTM (or SA572 Grade 50 in ASME). Bebon will offer S355JR and A572 Grade 50 structural steel plates with prime quality.
S355JR and A572 Grade 50 are low alloy steel grade. We will distinct these two alloy steel from two factors (chemical composition and mechanical property).
For main thickness (6-100mm), S355JR tensile strength is within 470-630Mpa, yield strength above 345Mpa. A572 Gr.50 tensile strength is min.450Mpa, yield strength above 345Mpa. This can be see as the same.
For five main chemical elements (C, Si, Mn, P, S), the heat analysis limited is also similar for S355JR and A572 Grade 50 steel plates. (See the below tables).
So when you are interested in S355JR steel plate, it is a good choice for you using A572 Gr50 to replacement of S355JR steel. We also provide S355JR steel plates and A572 Grade 50 steel plates with Mill Test and Other certificates.
