SAIL TMT HCR Corrosion Resistant TMT Bar

SAIL TMT HCR bars are meant for RCC exposed to coastal, marine, industrial or underground corrosive environments. In addition to the ductility of SAIL TMT EQR, they are alloyed with copper and chromium (total Cu+Cr at least 0.75%) for high corrosion resistance. Features: - Cu-Cr alloyed for high corrosion resistance (Cu+Cr 0.75% min) - For coastal, marine, industrial and underground exposure - Ductility and elongation of the EQR grades - 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 HCR, Fe 550D HCR, Fe 600 HCR Fe 500D HCR: YS 500 MPa min, UTS 565 MPa min, UTS/YS 1.10, elongation 16% Fe 550D HCR: YS 550 MPa min, UTS 600 MPa min, UTS/YS 1.08, elongation 14.5% Fe 600 HCR: YS 600 MPa min, UTS 660 MPa min, UTS/YS 1.06, elongation 10% Chemistry (max): C 0.25% (0.30% for Fe 600), 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
