ASTM A333 Grade 3 Grade 6 Grade 8 Grade 9 Alloy Steel Pipe Seamless Welded Pipe

1. A333 PIPE SPECIFICATIONS

A/SA333 NPS 1/4″ – 42″

Schedules 10 through 160, STD, XH and XXH

2. Scope

ASTM A333 covers nominal (average) wall seamless and welded carbon and alloy steel pipe intended for use at low temperatures. Several grades of ferritic steel are included. Some product sizes may not be available under this specification because heavier wall thicknesses have an adverse affect on low-temperature impact properties.

3. Material & Manufacture

The pipe shall be made by the seamless or welding process with the addition of no filler metal in the welding operation.

Heat Treatment Requirements

All seamless and welded pipe shall be treated to control their microstructure by the following methods: Normalizing per A 333/A 333M-05 section 4.3.1.1; section 4.3.1.2 or section 4.3.1.3 Quenched and Tempered per A 333/A 333M – 05 section 4.3.2.1 Double Normalized and Tempered per A 333/A 333M – 05 section 4.3.2.2

4. Chemical Requirements

		Composition, %
Element	Grade 1	Grade 3	Grade 6
Carbon, max	0.30	0.19	0.30
Manganese	0.40 – 1.06	0.31 – 0.64	0.29 – 1.06
Phosphorous, max	0.025	0.025	0.025
Sulfur, max	0.025	0.025	0.025
Silicon		0.18 -0.37	0.10 min
Nickel		3.18 – 3.82

For each reduction of 0.01% carbon below 0.30%, an increase of 0.05% manganese above 1.06% would be permitted to a maximum of 1.35% manganese. When Grade 6 is ordered under this specification, supplying an alloy grade that specifically requires the addition of any element other than those listed for the ordered grade is not permitted. However, the addition of elements required for the deoxidation of the steel is permitted.

5. Tensile Requirements

The material shall conform to the requirements as proscribed:

	Grade 1		Grade 3		Grade 6
	psi	MPa	psi	MPa	psi	MPa
Tensile Strength, min	55,000	380	65,000	450	60,000	415
Yield Strength, min	30,000	205	35,000	240	35,000	240
	Longitudinal	Transverse	Longitudinal	Transverse	Longitudinal	Transverse
Elongation in 2 in. or 50 mm, (or 4D), min, %:
Basic minimum elongation for walls 5/16 in. [8 mm] and over in thickness, strip tests, and for all small sizes tested in full section	35	25	30	20	30	16.5
When the standard round 2-in. or 50-mm gage length or proportionally smaller size test specimen with the gage length equal to 4D (4 times the diameter) is used	28	20	22	14	22	12
For strip tests, a deduction for each 1/32in. [0.8 mm] decrease in wall thickness below 5/16 in. [8 mm] from the basic minimum elongation of the following percentage	1.75	1.25	1.50	1.00	1.50	1.00

	Elongation in 2 in. or 50 mm, min, %:

Wall Thickness		Grade 1		Grade 3		Grade 6
in.	mm	Longitudinal	Transverse	Longitudinal	Transverse	Longitudinal	Transverse
5/16 (0.312)	8	35	25	30	20	30	16
9/32 (.281)	7.2	33	24	28	19	28	15
1/4 (.250)	6.4	32	23	27	18	27	15
