SAIL TMT EQR Earthquake Resistant TMT Bar

SAIL TMT EQR bars are made for reinforced concrete in buildings, bridges and other structures, particularly in earthquake-prone zones. They have high ductility (UTS/YS ratio), higher elongation, uniform elongation and a narrow range of yield strength, plus good bendability, weldability and fatigue resistance under dynamic loading. Features: - High ductility and uniform elongation for earthquake-prone zones - Narrow yield strength range - Good bendability and weldability - High fatigue resistance under dynamic loading - Made by Steel Authority of India at its integrated plants (Bhilai, Bokaro, Durgapur, IISCO) from iron ore - Conforms to IS 1786:2008 - Supplied in standard 12 m length; other lengths by agreement - Strapped bundles of about 2.5-5 tonnes Specifications: Grades: Fe 500D EQR, Fe 550D EQR Fe 500D EQR: YS 500 MPa min, UTS 565 MPa min, UTS/YS 1.10, elongation 16%, uniform elongation 5% Fe 550D EQR: YS 550 MPa min, UTS 600 MPa min, UTS/YS 1.08, elongation 14.5%, uniform elongation 5% Chemistry (max): C 0.25%, S 0.040%, P 0.040%, S+P 0.075% Diameters: 8, 10, 12, 16, 20, 22, 25, 28, 32 mm (SAIL rolls 6-40 mm; 6/8/10 mm also in coil form) Length: 12 m Source: Brochure: https://www.sail.co.in/sites/default/files/product-brochure/2022-04/TMT-Bars-Brochure-2022-new.pdf
