JUNE NEWSLETTER
- What
goes up must come down! Nickel has dropped from a high of $24.00 per
pound in May to $19.00 per pound. The recent fall is due to
increases in nickel inventory on the LME and new trading policies on
the Exchange. This will drive the August Surcharges down in both
304L and 316L. Looks like July will have the highest surcharges of
the year. Nickel averaged $23.67 per pound in May, thus pushing
upward the 304/304L surcharge to $2.2838 per pound. Moly pricing has
stayed elevated, coupled with high nickel; the 316/316L will
dramatically go up to $3.4734 per pound in July. Stainless lead
times are 6 to 14 weeks.
Carbon pricing is somewhat steady at
the moment and lead times are 5 to 8 weeks. |

HOT OFF THE PRESSES . . .
Keep in mind that Brighton
Tru-Edge Heads can heat treat your carbon steel heads. 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 1650º F +/- 50º F, ½ hour per inch of
thickness then air cooled. This heat treatment refines the grain structure
of the material.
-
Stress
relieving is 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%. For more details, see UCS-56. Stress relieving of SA-516-70 requires a
controlled heating and cooling as detailed in UCS-56 and held at 1100º F
minimum 1 hour per inch of thickness.
Brighton’s furnace capabilities allow us
to perform the heat treatments when required to meet customer and/or Code
requirements. For your information, 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.
