Combining values from the two systems may result in non-conformance with the standard.
The tempers of drawn tube shall be designated as light-drawn H55drawn H58and hard-drawn H Light-drawn bending temper is used only when a tube of some stiffness but yet capable of being bent is needed.
The b153 copper alloys are specified and classified according to their nominal compositions: A mercury nitrate test shall be done to detect and remove mercury vapor.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Nondestructive tests such as eddy-current test, hydrostatic test, and pneumatic test shall be done as well. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials.
Ten alloys are specified having the following nominal compositions:. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Ten alloys are specified having the following nominal compositions: Hard-drawn temper is used only where there is need for a tube as strong as is commercially feasible for the sizes indicated.
C, and UNS No. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.
ASTM B / BM – 17 Standard Specification for Seamless Brass Tube
Drawn temper is for general purposes and is most commonly used where there is no specific requirement for high strength on the one hand or for bending qualities on the other. The tubes shall undergo mechanical tests such as tension test, Rockwell hardness test, and expansion test in order to determine certain properties such as tensile strength and hardness.
Caution should be taken when handling mercury and mercury containing xstm.
Historical Version s – view previous versions of standard. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
For any combination of diameter and wall thickness not covered under hard-drawn temper, the values given for drawn temper shall be used. The tempers of annealed asmt shall be designated as light anneal O50 and soft anneal O This specification covers seamless round and rectangular including square copper alloy tube in straight lengths.
