Purpose:

This specification covers the engineering requirements for producing brazed joints in parts fabricated from austenitic corrosion and heat resistant steels, but may also be used on carbon or low-alloy steels or copper alloys, and the properties of such joints.

Application:

This process has been used typically for producing joints brazed between flexible metal hose, pressure fillings, pipe and tube joints, and similar parts, such as bellows and rigid end fittings where one end of the joint is not accessible for inspection, but usage is not limited to such applications.

Classification:

The brazing procedure is classified by the maximum service temperature as follows:

Type 1 600 °F (316 °C) service temperature

Type 2 400 °F (204 °C) service temperature

Type 3 800 °F (427 °C) service temperature

If a type is not specified, Type 1 shall be supplied.

Maximum operating pressures will vary with part geometry and should be specified by purchaser.

Safety - Hazardous Materials:

While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards which may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.

Warning: Numerous scientific studies have determined that cadmium, which is used in some brazing alloys, presents a health hazard to persons who are exposed to it.
