Quenching Oil Durixol V35 (extremely fast)

Durixol V35 is the fastest hardening oil on the market and is particularly suitable for hardening workpieces made from unalloyed and low-alloy tool steel. It has a significantly faster cooling rate than the well-known American hardening oil "Park's 50". 

Durixol V35 achieves an extremely fast cooling rate in the boiling phase and a slower cooling rate in the martensitic transformation range (Ms-Mf). This reduces the risk of warping and cracking. At the same time, the complete hardening of unalloyed tool steels is guaranteed with cross-sections customary for knives. 

This hardening oil is particularly suitable for hardening blades made of unalloyed and low-alloy tool steels which, due to their geometry, are not prone to severe hardening distortion. With cross-sections customary for knives, this hardening oil can also be used to harden tool steels that are designated as water hardeners. 

If mainly low-alloy and medium-alloy tool steels are to be hardened, I recommend the hardening oil AAA-DA, which has a somewhat gentler quenching rate in the boiling phase and a significantly slower cooling rate in the martensitic transformation range (Ms-Mf). Also available here in the shop.
