    DIN EN AISI
    1.2235 80CrV2 L2 (sometimes)


    Chemical Composition (in weight %)

    C Si Mn Cr Mo Ni V W Others
    0.80 0.33 0.40 0.55 - 0.20

    Description
    Low alloyed Cr-V cold working steel.

    Applications
    Circular saws for timber, saws for non ferrous, machine saws, measuring tools, tools for wood working axes, knives, punches, guide rods, twist drills, reamers, ejector pins, dentist's drills.

    Soft Annealing
    Heat to 710-850C, cool slowly in furnace.
    This will produce a maximum Brinell hardness of 220.

    Stress Relieving (Normalizing)
    Stress relieving to remove machining stresses should be carried out by heating to approx. 650C, holding for 1-2 hours at heat, followed by air cooling.
    This operation is performed to reduce distortion during heat treatment.

    Hardening
    Harden from a temperature of 810-840C, 780-810C followed by oil (up to diameter 15 mm) or water (for diameter higher then 15 mm) quenching Hardness after quenching is 64 HRC.

    Tempering
    Tempering temperature: See the data below.

    Tempering Temperature (C) vs. Hardness (HRC)

    100C 200C 300C 400C
    64 62 57 51

    Forging
    Hot forming temperature: 1050-850C.

    Hi, in a different thread you said the following:

    I thought it might be better to ask my question here instead: If 80Crv2 is improved 1084, should I consider using it by default and not just when in a pinch?

    I actually bought some because I couldn't find 108x and haven't used it yet. Every description I read says describes it similarly to you, but it seems to be uncommon in use.

    It does get used a fair bit for choppers and such but the biggest issue is 1084 is an American designation and 80Crv2 is not. For myself I look at it as a good choice for beginners and use it for first time when trying something new or making small knives for kids. Keeps the price down and they have to learn upkeep while giving them a good steel without going over the top.
