The only thing you amy notice is a lower toughness on the CA6NM as it is a cast steel. The Forged version F6NM will give you better impact resistance, due to the wrought nature of the structure.

I suspect it may be related to the Quench process. 1144 is basically a carbon steel, and may harden better in a water quench.

4330 v mod is stocked by many oilfield distributors in bar form, at 150 ksi min yield strength. in some cases as high as 165 min yield.

As was mentioned earlier, the main benefit of the cold drawn bar will be in dimensional control. The cold drawn grain size benefit will not transcend deep into the bar, as the drawing process will not elongate or refine the structure deep into the 5 inch diameter component. It will likely only...

410 per NACE needs to be Rc 22 max, and also needs to be quenched and double tempered to be in compliance to NACE. Be careful not to go higher that the first tempering temperature when you set up the stress relief of your 625 weld, or you will likely degrade the base metal 410 properties. I have...

The grade you are looking for is Hatfields Manganese Steel. It is commonly used for Jaw crushing equipment(scrap processors), and ore crushers. Generally in cast form. Highly work-hardenable alloy.

I am looking to substantiate the use of 6061 T-6 as an actuator valve cap in the following environment: 79.5% Methane 1.55% Ethane .35% propane 11.77% mole Nitrogen 6.35% mole Carbon Dioxide .06% mole Hydrogen Sulphide Dew point of gasses 8.0 Pressure absolute (psia) 264.6 indicated gage...

I found it in Woldmans. It is basically a type H-11 tool steel, and is registered under U.N. Alloy Steel Corp. They are in Revere, MA 02151. Hope this helps.
