What does E250 mean in IS 2062?

It is the minimum yield strength: 250 MPa. E350 has 350 MPa, and so on.

Grade E250 in quality BR, which means its toughness has been impact tested at room temperature.

How much does an MS plate weigh?

7.85 kg per square metre for every millimetre of thickness. A 10 mm plate weighs about 78.5 kg per square metre. Use the steel weight calculator for other sizes.

Is IS 2062 the same as ASTM A36?

They are close: A36 has a minimum yield of 250 MPa like E250. Small differences in chemistry and testing exist, so state the standard you need.

Mild steel IS 2062

Also called: MS plate, E250, E350, IS 2062 E250 BR, structural steel, ASTM A36, S275

IS 2062 is the Indian standard for hot-rolled structural steel, the everyday "MS" plate, sheet and section used in fabrication. The grade number (E250, E350, …) is the minimum yield strength in MPa; it is easy to cut, bend and weld.

Quick facts

Type: Hot-rolled structural (mild) steel
Most used grade: E250 (yield 250 MPa min)
Higher strength: E350, E410, E450
Weldability: Excellent
Density: 7.85 g/cm³ (a 1 m² plate weighs 7.85 kg per mm of thickness)
Forms: Plates, sheets, angles, channels, beams, flats

Grades and strength

Grade	Yield strength (min)	Tensile strength (min)	Elongation (min)
E250	250 MPa	410 MPa	23%
E350	350 MPa	490 MPa	22%
E410	410 MPa	540 MPa	20%
E450	450 MPa	570 MPa	20%

Yield strength is lower for thick plates; the standard gives values by thickness.

Quality letters: A, BR, B0, C

A: no impact test
BR: impact tested at room temperature
B0: impact tested at 0 °C
C: impact tested at −20 °C, for cold or shock conditions
So "E250 BR" means 250 MPa yield, impact tested at room temperature

Closest equivalents

Standard	Grade
ASTM (USA)	A36 is close to E250; A572 Gr 50 is close to E350
EN 10025 (Europe)	S235 / S275 near E250; S355 near E350

Typical uses

Fabricated frames, structures and sheds
Machine bases, guards and covers
Base plates, brackets and gussets
Tanks and chutes (not pressure parts)
Laser- and plasma-cut profiles

Working with it

Cuts cleanly by laser, plasma, gas or shearing
Bends easily on a press brake
Welds by MIG, stick or SAW without preheating in usual thicknesses
Needs painting, galvanising or powder coating against rust
