Differences Between Normalized and Annealed 4130 Steel ...

Normalizing is a similar process to annealing except that the metal is heated to a higher temperature and cooled slowly over hours or even days. This slow cooling removes almost all the internal stress within 4130 steel and creates a ductile material with a higher tensile strength compared to annealed steel at 106,000 psi.

Normalize 4130 After Weld - Can We Do It This Way?

Apr 23, 2007 · The recommended normalizing temperature for 4130 is 1600F, followed by air cool. This is a true "heat treatment", causing microstructural change both upon heating/holding at 1600F and air cooling back to room temperature. PWHT of a weldment in 4130 is done at a temperature below that which will cause microstructural changes.

Nov 29, 2005 · Normalized 4130 is best to use for fabrication because it's workable, weldable, and still strong without post fab heat treatment. Design, fit up, and prep is just as important as the choice of material and welds I have posted a lot on this before. There's lots of it on this board somewhere.

hardening 4130 - Metal and Metallurgy engineering - Eng-Tips

Aug 16, 2011 · 4130 will harden to HRC 51 by water quenching. After tempering at 500 the hardness will be less. You can carburize 4130 for higher surface hardness up to 65 HRC if you have enough pieces to justify the cost of a furnace run. If you have only one piece, you can use Kasenite to surface harden with an oxy-acetelyne torch.
