AISI 4320 Strength - Metal and Metallurgy engineering Oct 09, 2007 · 4320 can easily meet the tensile and hardness properties by quenching into oil or water and then tempering in the range of 400-450 C. ASM HANDBOOK Volume 1 has some data on Q&T 4330 that shows CVN ~ 45 lb-ft (~ 70 J) at -40 C based on a hardness of 269 HB (~ 27.5 HRC).
