JINDAL PANTHER Fe 500D is the lower-strength grade shown beside Fe 550D in the brochure's BIS comparison table and stress-strain curve. The brochure gives its Jindal Panther chemistry and mechanical values and a guaranteed 18 % elongation. The brochure focuses on Fe 550D and states no diameter range for Fe 500D.

Key features

• Iron-ore based steel with modern ladle refining
• Controlled chemistry (P+S < 0.075 %)
• Made by HYQST (Patratu) / QST (Angul) thermo-mechanical treatment: hard tempered-martensite surface with soft ferrite-pearlite core
• Precise, uniform parallel rib pattern for bond strength with concrete
• Panther face embossing on the bar and ISI mark with licence number
• Low alloying route with low carbon keeps the steel ductile and weldable

Applications

• Marine, coastal and saline environments
• High seismic zones
• Airports, roads, bridges, buildings, refineries, power plants, metros, ports and dams
