ASTM A358
ASTM A358
Standard: ASTM A358, ASME B36.19M, ASME B36.10M
Alloy: 304/304L, 305, 316/316L
(DIN 1.4301, 1.4307, 1.4401, 1.4404)
Five classes of ASTM A358 pipe are covered as follows:
1.3.1 Class 1—Pipe shall be double welded by processes employing filler metal in all passes and shall be completely radiographed.
1.3.2 Class 2—Pipe shall be double welded by processes employing filler metal in all passes. No radiography is required.
1.3.3 Class 3—Pipe shall be single welded by processes employing filler metal in all passes and shall be completely radiographed.
1.3.4 Class 4—Same as Class 3 except that the weld pass exposed to the inside pipe surface may be made without the addition of filler metal (see 6.2.2.1 and 6.2.2.2).
1.3.5 Class 5—Pipe shall be double welded by processes employing filler metal in all passes and shall be spot radiographed.
Specification :
Application of Stainless Steel ASTM A358 Pipe: Corrosive or high temperature application
OD Tolerance: +/-0.5%
Out-off Roundness: Difference betwen major and minor outside diameters 1% (真圓度)
Thickness Tolerance: -0.3mm
Additional requirement available for ASTM A358:
S1. Product Analysis
S1.1 Product analysis shall be made on each length of pipe. Individual lengths failing to conform to the chemical composition requirements shall be rejected.
S2. Tension and Bend Tests
S2.1 Tension tests (Section 12) and bend tests (Section 13) shall be made on specimens to represent each length of pipe. Failure of any test specimen to meet the requirements shall be cause for the rejection of the pipe length represented.
S3. Penetrant Oil and Powder Examination
S3.1 All welded joints shall be subjected to examination by a penetrant oil and powder method. The details of the method and the disposition of flaws detected shall be a matter for agreement between the purchaser and the manufacturer.
S4. Ferrite Control in Weld Deposits
S4.1 The ferrite content of the deposited weld metal in any length of pipe may be determined. The procedural details pertaining to this subject (that is, welding; plate and weld deposit chemistry; testing equipment and method; number and location of test sites; and ferrite control limits) shall be a matter for agreement between the purchaser and the manufacturer.
S5. Stabilizing Heat Treatment
S5.1 Subsequent to the heat treatment required in 6.3, Grades 321, 347, and 348 shall be given a stabilization heat treatment at a temperature lower than that used for the initial solution annealing heat treatment. The temperature of stabilization heat treatment shall be at a temperature as agreed upon between the purchaser and vendor.
S6. Intergranular Corrosion Test
S6.1 When specified, material shall pass intergranular corrosion tests conducted by the manufacturer in accordance with Practices A 262, Practice E. NOTE S1—Practice E requires testing on the sensitized condition for low carbon or stabilized grades, and on the as-shipped condition for other grades.
S6.2 A stabilization heat treatment in accordance with Supplementary Requirement S5 may be necessary and is permitted in order to meet this requirement for the grades containing titanium or columbium.
