IS 2062:2011 — Clause Reference

Grades & Designation (E165 / E250 / E350 / E450 …)

IS 2062 designates structural steel by minimum yield strength — E165, E250, E350, E410, E450 (N/mm²) — and by quality gr…

Chemical Composition & Carbon Equivalent (Weldability)

IS 2062 limits carbon, sulphur, phosphorus and — critically — the carbon equivalent (CE), tighter for the higher quality…

Mechanical Properties — Yield, Tensile, Elongation

IS 2062 fixes minimum yield strength (the E-number — note it reduces for thicker sections), ultimate tensile strength, a…

Notch Toughness — Charpy Impact & Brittle Fracture (Quality C/D)

The higher IS 2062 quality grades (notably C and D) carry Charpy V-notch impact requirements at specified test temperatu…

Quality Levels, Sampling & Acceptance

IS 2062 acceptance is a chain: representative sampling, cast/product chemical analysis (CE), tensile test (IS 1608), ben…
