What You Should Consider When Purchasing Modified P20
Nov 01, 2004 · The higher the content, the more difficult it is to get a mirror finish. Sulfides tend to erode or be pulled out of the surface during the polishing process, resulting in a pitted surface. Most P20s will polish to a good #2 finish. The best P20 in terms of polishability is probably #3 steel, due to its extremely low sulfur content.Technical Information: 4140 HT - SB Specialty Metals4140 HT Surface Hardening . 4140 HT is a medium carbon alloy steel heat treated to a . nominal hardness of 28-32 HRC. 4140 HT can also be surface hardened to increase wear resistance .

Is there a maximum hardness level for 4140?
The maximum hardness that can be obtained in any steel depends on carbon content. The section size in which maximum hardness can be obtained depends on alloy content. 4140 has a nominal carbon content of .4% and this carbon content will yield a hardness of Rc 51 for a 90% martensitic structure (9th Edition of the ASM Material Handbook,Volume I).See all results for this questionHeat-Treating & Hardening 4140 Steel - Material buy 4140 steel spec Surface treatmentJun 30, 2006 · 4140 is not used for carburizing, but it can be surface hardened using induction.
