RE: [MW:31184] Re: Annealing and Normalizing temperature for F316 & SS410

SURESH,

 

Yes, SS410 steel can be purchased, in annealed condition, or in a tempering condition with prior normalization, as stated in ASTM A479, point 4.4.1. But the question is what are you going to do with the steel, are you going to weld it, machine it, or use it directly in its state of supply (annealed)?

If you are going to use it in a welding condition, since the annealing structure is lost, instead hard hardening structures such as martensite are formed. Then a tempering must be done to preserve the best hardness and toughness properties and that the piece does not suffer from hydrogen-induced cold cracking.

Thanks Mr.Ramon Briceno

 

But my client is suggesting to do annealing for ASTM A473 Typ410 at the temperature of 950 C (Customer mentioned TDC). Is there any adverse effect on the change of hardness?

Dear Experts

Kindly let us know the Annealing and Normalizing temperature for below material grade

 

1.ASTM A473 Typ410- Annealing and Normalizing temperature

 

2.ASTM A182 F316- Solution Annealing and Normalizing temperature

 

 

Kindly let us know this temperature is anywhere mentioned in the standard
