Product Description

ASME SA-210 SPECIFICATION FOR SEAMLESS MEDIUM-CARBON STEEL BOILER AND SUPERHEATER TUBES

Chemical Composition (max. %)

Element	Grade A-1	Grade C
C	0.27	0.35
Mn	0.93	0.29-1.06
P	0.035	0.035
S	0.035	0.035
Si	≥0.10	0.10

For each reduction of 0.01% below the specified carbon maximum, an increase of 0.06% manganese above the specified maximum will be permitted up to a maximum of 1.35%.

Tensile Requirements

Element	Grade A-1	Grade C
Tensile strength, min, ksi [MPa]	60 [415]	70 [485]
Yield strength, min, ksi [MPa]	37 [255]	40 [275]
Elongation in 2 in. or 50 mm, min, %	30	30
For longitudinal strip tests, a deduction shall be made for each 1/32 in. [0.8mm] decrease in wall thickness under 5⁄16 in. [8 mm] from the basic minimum elongation of the following percentage points	1.50 A	1.50 A
When standard round 2 in. or 50 mm gage length or smaller proportionally sized specimen with the gage length equal to 4D (four times the diameter) is used	22	20
