Product Description

Product Description

ASTM A333 is the standard specification for seamless and welded steel pipe for application in low temperature services and other applications with the required notch toughness.

 

All the seamless and welded steel pipe, except ASTM A333 Grade 8 and Grade 11, shall be treated to control the microstructure in one option as follows,

1. Normalized in a uniform temperature not less than 815ºC [1500ºF], and cool in air or in the cooling chamber of an atmosphere controlled furnace, or after this heat treatment then heating to a suitable temperature to do the termpering.

2. Besides above heat treatment option, and with manufacturers will, reheat material to a suitable tempering temperature.

3. In case the seamless steel pipe in the ASTM A333, reheat and control hot working and the temperature of the hot finishing operation to a finishing temperature range from 845 to 945ºC [1550 to 1750ºF], and cool in air or in a controlled atmosphere furance from an initial temperature more than 845ºC [1550ºF]. For the ASTM A333 seamless steel pipe in Grade 1, Grade 6, and Grade 10 could be heat treated from a uniform temperature more than 815ºC [1500ºF], then quenching in liquid and reaheat to a suitable tempering temperature, this type of heat treatment could replace the above plan also provided the ASTM A333 4.3.1. For the ASTM A333/ A333M Grade 8 and Grade 11, heating treatment shall be complied the standard specification.

For the ASTM A333 Grade 1, Grade 6 and Grade 10 steel pipe, and it is not allowed to add the chemical element not specified in the specification, but it is allowed to add the element for the deoxidation of steel.
