Before you call

Heat treating: the short version

Heating and cooling metal in a set cycle to harden, soften or relieve stress.

When you need it

  • Stress relief after welding
  • Hardening machined parts
  • Annealing before more forming
  • Code jobs that call for PWHT

What to send the shop

  • Material grade
  • The spec or hardness you need
  • Part size and weight
  • How many parts

Typical lead time

Houston heat treaters quote per load. Ask how often they run your cycle.

Ask the shop

3 questions worth asking

  1. Q1

    Do you give a chart or certificate with each load?

  2. Q2

    What is the largest part your furnace takes?

  3. Q3

    Is there a minimum charge per load?

Questions

Heat treating FAQ

How big a part can Houston shops heat treat?

Mach Industrial Group lists heat treatment up to 60 x 109 x 300 inches at 2400 degrees F, with a water quench.

Who does post weld heat treatment?

Superior Cladding Products runs a 110 inch car bottom furnace and a smaller 50 inch furnace for stress relief.

Do Houston foundries heat treat castings?

Some do. Coastal Foundry 2.0 lists T5 and T6 heat treatments with its castings.

Good to know

  • Send the spec. The cycle comes from it.
  • Ask for the furnace chart with your parts.
