^B Grades shown in this table with the letter B, such as 50B40, can be expected to have 0.0005 % minimum boron control. ^A  Grades shown in this table with prefix letter E generally are manufactured by the basic-electric-furnace process. All others are normally manufactured by the basic-open-hearth process but may be manufactured by the basic-electric-furnace process with adjustments in phosphorus and sulfur.

 

^C  The phosphorus sulfur limitations for each process are as follows:

Basic electric furnace         0.025 max %         Acid electric furnace          0.050 max %

Basic open hearth            0.040 max %          Acid open hearth             0.050 max %

^D Minimum and maximum sulfur content indicates resulfurized steels.

^EThe purchaser may specify the following maximum amounts: copper, 0.30 %; aluminum, 0.050 %; and oxygen, 0.0015 %.

A Wall thickness tolerances may not be applicable to walls 0.199 in. (5.05 mm) and less; consult manufacturer for wall tolerances on such tube sizes. a more important dimension, then cold-worked tubing should be specified to inside diameter and wall thickness or outside diameter and inside diameter.  Rough-Turned Mechanical Tubing—Variation in outside diameter and wall thickness shall not exceed the tolerance in Table. Table  covers tolerances as applied to outside diameter and wall thickness and applies to the specified size.  Ground Mechanical Tubing—Variation in outside diam-eter shall not exceed the tolerances in Table. This product is normally produced from a cold-worked tube.  Lengths—Mechanical tubing is commonly furnished in mill lengths, 5 ft (1.5 m) and over. Definite cut lengths are furnished when specified by the purchaser. Length tolerances are shown in Table . Straightness—The straightness tolerances for seamless round tubing shall not exceed the amounts shown in Table.

 

Test Requirement

1.Hardness Test
When hardness limits are required, the manufacturer shall be consulted. Typical hardnesses are listed in Table .When specified, the hardness test shall be performed on 1 % of the tubes.

2.Tension Tests
When tensile properties are required, the manufacturer shall be consulted. Typical tensile properties for some of the more common grades and thermal conditions are listed in table.

3.Nondestructive Tests
Various types of nondestructive ultrasonic or electromagnetic tests are available. The test to be used and the inspection limits shall be established by manufacturer and purchaser agreement.

4.Flaring Test
When there are special requirements for steel cleanliness, the methods of test and limits of acceptance shall be established by manufacturer and purchaser agreement.
