B500B Reinforcing Steel: Properties, Chemistry & Where It’s Used
B500B reinforcing steel is a routine purchase that quietly decides project cost and quality. Get the grade and paperwork right and everything downstream is smoother. Below we break down B500B reinforcing steel — specifications, standards, logistics and the buyer levers that cut your landed price.
What B500B is
B500B (DIN 488/EN 10080) is the European default — 500 N/mm² yield, ductility class B, fully weldable. B500C adds high ductility (Agt ≥7.5%) for seismic work; Grade 60 (ASTM A615) is the 420 MPa class common in the Gulf and Americas.
B500B sits in that landscape as a 500-MPa-class general-purpose bar.
Properties that matter
Specify by yield strength, ductility class (elongation Agt and yield ratio), weldability (controlled carbon equivalent) and bar size. Every shipment ships with an EN 10204 3.1 mill test certificate tied to the heat number, recording chemistry, tensile results and bend/rebend tests — your full traceability chain.
Choosing it for a project
Match the grade to the design code and, for seismic detailing, to the required ductility class. Dual-certified material bridges spec conflicts between EN and ASTM.
FAQ
Is B500B weldable?
Generally yes when the carbon equivalent is controlled — confirm with the mill data on the 3.1 certificate.
Where is B500B used?
European and international projects on the 500-class.
Can you dual-certify it?
Often yes (EN 10080 + ASTM A615) — send your spec.
