JIS G3459 SUS310 Stainless Steel Pipe
Standard:JIS G3459
Scope
JIS G3459 Standard specifies the stainless steel pipes (hereafter referred tp as "pipes") used for the pipings for corrosion resistance, low temperature sevice, high temperature service, etc.
SUS310 and SUS310S are the steel grades in JIS G3459 standard.
Method of manufacture
Pipes shall be manufactured by a seamless process, an automatic arc welding process, a laser welding process, or an electric resistance welding process.

Dimensional tolerances
The tolerances on outside diameter, wall thickness, and eccentricity of pipe
Tolerances on outside diameter, wall thickness and eccentricity
| Division | Tolerances on outside diameter | Tolerances on wall thickness | Tolerances on eccentricity |
| ot-finished seamless pipe | Under 50mm 【0.5mm | Under 4mm 【0.5mm |
At most 20 % of wall thickness
|
| 50mm or over 【1% | 4mm or over 【12.5% | ||

Cold-finished seamless pipe, automatic arc welded pipe, electric resistance welded pipe, and laser welded pipe |
Under 30mm 【0.3mm | Under 2mm 【0.2mm | --- |
| 30mm or over 【1% | 2mm or over 【10% |
Remarks
The eccentricity means the ratio of the difference between maximum and minimum wall thickness measured in the same section to the specified wall thickness, and this shall not be applied to pipes under 5.6mm in wall thickness..
As for the portions locally ground or the like, the above tolerance on outside diameter shall not be applied if it is confirmed that the wall thickness is within the tolerance range given in the above table.
Tests
Chemical analysis
General matters common to chemical analysis and the method of sampling specimens form analysis shall be in accordance with 3. in JIS G 0303.
Analytical method the analytical method shall be in accordance with any one of the following standards
JIS G 1211, JIS G 1212, JIS G 1213, JIS G 1214, JIS G 1215, JIS G 1216,JIS G 1217, JIS G 1218, JIS G 1223, JIS G 1224, JIS G 1237, JIS G 1253,JIS G 1256, JIS G 1257
Tensile test
Test piece
The test piece shall be any one of No.11, No. 12A, No. 12B, No.12C, No.4 or No. 5 specified in JIS Z 2201 to be cut off from the pipe. IN the case of No. 4 test piece, the gauge length shall be 50mm.
Test method
The test method shall be in accordance with JIS Z 2241
Flattening test
Test piece
A length 50mm or over of a pipe shall be cut off from the end of the pipe to serve as a test piece. For the pipe whose wall thickness is 15 % or over of the outside diameter, a C-shape test piece made by removing a part of the circumference of a ring-shaped test piece may be used.
Test method
Place the test piece at ordinary temperature between two flat plates and flatten by compression until the distance between the flat plates reaches the specified value, and examine for the occurrence of flaws or cracks on the wall surface of the test piece. In the cases of the automatic arc welded pipe, laser welded pipe, and electric resistance welded pipe,the weld zone shall be placed at right angles to the direction of compression as shown in Fig 2, and the C-shape test piece shall be placed as shown in Fig. 3.
Austenitic grain size test
Test piece
A 20mm long pipe shall be cut off from the pipe end to serve as a test piece..
Test method
The austenitic grain size number shall be measured in accordance with JIS G 0551.
Hydraulic test or nondestructive examination
Hydraulic test
When the pipe is subjected to a hydraulic pressure and kept at the specified pressure for 5 s or longer, whether it withstands the pressure without leakage shall be examined.
Nondestructive examination
The test method of a nondestructive examination shall be in accordance with JIS G 0582, JIS G 0583 or JIS Z 3106.
Appearance
JIS G3459 SUS310、SUS310S Pipes shall be straight for practical purposes, and their both ends shall be at right angles to the axis.
The inside and outside surfaces of the JIS G3459 SUS310、SUS310S pipes shall be well finished, and free from defects detrimental to practical use.
