Principal Design Features
This specification covers seamless and welded steel pipe for low temperature service. The Grade 6 alloy steel involved is similar to AISI 4032 low alloy steel.
Used for low temperature service piping down to minus 50 F.
Machinability is good, similar to law alloy 4032 steel.
The product comes in piping form but may be formed readily by conventional methods.
Weldable by conventional methods.
Product is supplied in the normalized, 1500 f and air cooled, condition. It may be quenched and tempered by heating to 1475 F, quench in circulating water and then temper by re-heating to 1100 F and rapid air cooling.
Product is supplied in pipe form and not normally forged from that shape.
Hot working may be done qt 2000 F down to 1600 F if need be. Do not hot work below 1550 F and immediately following hot working cool in a controlled atmosphere furnace from a temperature above 1550 F.
Cold working may be done by conventional methods.
Anneal, or normalize, at 1600 F and air cool.
See "Heat Treatment"
Hardens from cold working or heat treatment. See "Heat Treatment".
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.

A333 useful information
Grade 6 is a low alloy steel similar to 4032 in properties. Tensile strength requirement for Grade 6 is 60 ksi minimum and notched-bar impact strength is 4 to 13 ft. lbs. depending upon section size.
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.
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 188.8.131.52; section 184.108.40.206 or section 220.127.116.11 Quenched and Tempered per A 333/A 333M – 05 section 18.104.22.168 Double Normalized and Tempered per A 333/A 333M – 05 section 22.214.171.124
The material shall conform to the requirements as proscribed:
Tensile Strength, min
Yield Strength, min
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
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
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
Elongation in 2 in. or 50 mm, min, %:
For Grades 1, 3 and 6, the notched-bar impact properties of each set of three impact specimens, including specimens for the welded joint in welded pipe with wall thicknesses of 0.120 in. [3 mm] and larger, shall not be less than the values prescribed:
Size of Specimen, min
Minimum Average Notched Bar Impact Value of Each Set of Three Specimens
Minimum Notched Bar Impact Value of One Specimen Only of a Set
Min Impact Test Temp
10 by 10
10 by 7.5
10 by 6.67
10 by 5
10 by 3.33
10 by 2.5
Transverse or Longitudinal Tension Test and Flattening Test, Hardness Test, or Bend Test For material heat treated in a batch-type furnace, tests shall be made on 5% of the pipe from each treated lot. For small lots, at least one pipe shall be tested. For material heat treated by the continuous process, tests shall be made on a sufficient number of pipe to constitute 5% of the lot, but in no case less than 2 pipe. Hydrostatic Test Impact Test One notched bar impact test, consisting of breaking three specimens shall be made from each heat represtented in a heat-treatment load on specimens taken from the finished pipe.
Lengths required shall be specified on order. If no definite lengths required, following practice applies: Single Random — 17′ ~ 24′ lengths Double Random — 36′ ~ 44′ lengths
Required Markings on Each Length
(On Tags attached to each Bundle in case of Bundled Pipe) Markings will adhere to prescribed specifications in A 999/A999M and be: Rolled, Stamped, or Stenciled (Mfrs. Option) In addition, markings will include:
Hot Finished or Cold Drawn
Specification / Grade
Hydro or NDE
Seamless or Welded
the letters “LT” followed by the temperature at which the impact tests were made * and **
the letters “QT” when the pipe is furnished in the quenched and tempered condition
* except when a lower test temperature is required because of reduced specimen size, in which case, the higher impact test temperature applicable to a full size specimen would be marked ** when the size of the finished pipe is insufficient to obtain subsize impact specimens, the marking shall not include the letters “LT” followed by an indicated test temperature unless Supplementary Requirement S! is specified.

ASTM A333 Grade 6 Carbon Steel Seamless Pipe FAQ
How SA106 is different from A106? SA means that the ASTM standard has been approved / adopted by the BPVC (Boiler & Pressure Vessel Code by ASME). Examples: ASME says about ASTM A53: there are no differences. ASME says about ASTM A106: Identical, except for editorial differences at 8.1, 13.4, and 24.1 and deletion of ASTM caveat 1.5 (these are articles referring to the BPVC).
