Did you know that Brighton Tru-Edge Heads can heat treat
your carbon steel heads? Brighton’s furnace
capabilities allow us to perform the heat treatments when required to
meet customer and / or Code requirements. Thermocouples are attached
to the heads to ensure proper heating of the material. Our computer
controlled furnaces are equipped to program the required heat treat cycle
which is documented on a heat chart.
There are two main heat treatments performed on
SA-516-70 material.
Normalizing is a heat treatment performed
on the material, either in the flat or when required, after forming,
above the critical transformation temperature. For SA-516-70, the
normalizing cycle is 1650° F +/-50°, ½ hour per inch of thickness then
air cooled. This heat treatment refines the grain structure of the
material.
Stress relieving is
a heat treatment mainly performed to relieve work hardening stresses in
the material. On cold formed heads, the ASME Code requires some
heads to be stress relieved when the fiber elongation exceeds 5%. Stress
relieving of SA-516-70 requires a controlled heating and cooling as
detailed in UCS-56 and held at 1100° F minimum for 1 hour per inch of
thickness. Note: There are some exemptions to the stress relieving
requirements even if the fiber elongation exceeds 5%. These
exemptions are listed in ASME Section VIII Division
1, UCS-70(d).
