Principal Design Features
|
|
This specification covers seamless and welded steel pipe for low temperature service. The Grade 6 alloy steel involved is similar to AISI 4032 low alloy steel.
|
|
|
Applications
|
|
Used for low temperature service piping down to minus 50 F.
|
|
|
Machinability
|
|
Machinability is good, similar to law alloy 4032 steel.
|
|
|
Forming
|
|
The product comes in piping form but may be formed readily by conventional methods.
|
|
|
Welding
|
|
Weldable by conventional methods.
|
|
|
Heat Treatment
|
|
Product is supplied in the normalized, 1500 f and air cooled, condition. It may be quenched and tempered by heating to 1475 F, quench in circulating water and then temper by re-heating to 1100 F and rapid air cooling.
|
|
|
Forging
|
|
Product is supplied in pipe form and not normally forged from that shape.
|
|
|
Hot Working
|
|
Hot working may be done qt 2000 F down to 1600 F if need be. Do not hot work below 1550 F and immediately following hot working cool in a controlled atmosphere furnace from a temperature above 1550 F.
|
|
|
Cold Working
|
|
Cold working may be done by conventional methods.
|
|
|
Annealing
|
|
Anneal, or normalize, at 1600 F and air cool.
|
|
|
Tempering
|
|
See "Heat Treatment"
|
|
|
Hardening
|
|
Hardens from cold working or heat treatment. See "Heat Treatment".
