Question 9260 Spring Steel

I want to make a Katana out of 9260 spring steel. and was wondering if anyone had used it and if so, what did you think? I came across it from this web site http://www.chenessinc.com/9260.htm . I would appreciate your knowledge

I've never used it, but I've heard more then once, from more then one knowledgable person, that it's awfully similer to 5160. Should be great sword steel unless you're trying to get the traditional hamon. If you want the hamon then you either want a 10xx steel, or a W steel.

9260, or at least S-5 (a higher alloy version of 9260), is the toughest high hardness steel there is. It is tougher than S-7, and gets harder. My guess is it has very few, if any, carbides, and they are very small.

Thanx Larrin

Thankx for the info Larrin, I am going to add it to my info. I have yet to make a forged sword. Basiclly I have used the cut and grind method. I have used some very nice weapons in my training of Ninjutsu, But I can't buy half of the weapons because of the legalities where I live (Sherikin, Nunchuck ect....) So I have to make my own. Which is great, I love to make things from steel. Thanx again

I have forged quite a bit of 9260 and I cannot tell any difference from 5160. It is a very underutilized steel and it's very affordable.

Have you done any rope cutting comparisons? I wonder how much wear resistance they have. I think Wayne Goddard said that he couldn't get either S5 or S7 (can't remember which) to cut very well.

I have not done any rope cutting but I did make a brush chopper out of 9260. It held up cutting black berry vines (dried), wild rose canes, scotch broom, elderberry limbs etc. The edge is still there and very sharp.

9260 will hold as well, and in some cases slightly better than 5160. I've switched from 5160 to 9260 because of all the issues I was having with inclusions in 5160. Forging and heat treatment are nearly identical to 5160, no noticeable difference in grinding or finishing.

An excellent 'spring steel' very similar to 5160. In the old days when I was a fencer the blades were 9260. Just one caution ,the high silicon content makes is more easily cause decarb.

I never intentionally ordered 9260 but a couple years ago I ordered some 5160 from Admiral and they sent 9260 instead. So I decided to play around with it and ended up really liking it.

Dpanther, there are many steels that are used as springs therefore may be called 'spring steel '. Both 5160 and 9260 and their modifications have been used for suspension springs for vehicles.

Re: 9260 Spring Steel

I have made one knife out of 9260, and in my opinion, it works better than the 1095 that I have been working with and made a blade you could shave with. Is there a supplier, other than Admiral which only has 1X1/4" size, that sell this steel the the small purchaser?
