    15n20 is basically 1075 with 2% nickel, it does not have any chromium.

    I got answer from Bohler-Uddeholm Sweden today, they say it contains 0.11% Cr

    BU corp buys the stock from more than one supplier and then they roll and process it in to strip and saw blade material. There are some which contain a little chrome and some do not. Chrome is added to refine the grain.

    BU corp does make sure that all of its material falls within a very narrow parameter of chemical make up.

    This is an awesome thread! So much knowledge!

    Devin just curious at this point in time which stainless and which carbon would you choose as the best all around guyto steels?

    AEB-L for stainless and 52100 for carbon always make me happy. My studies right now are on more PM grades along with a few tool steels.
    Also, we are doing a bunch of research on heat treatments more than focusing on specific grades of steel.

    Devin - Great thread! Can you give us any insight into how some of the steels like M390 and HAP40 would rate?
    Thanks..

    I have heard that HAP40 is quite the steel how come we don't see it being used much?

    Both are very good steels. They are very expensive and very difficult to heat treat. They both have very good edge holding and are a little on the brittle side. HAP40 is made by Hitachi. I don't think that we can even get that grade here. I'm leaning more towards simpler grades with lower heat treat temperatures that are more readily available.

    what can be compared to HAP40 as far as wear resistance goes?
