420hc is barely a steel

I read a knife review moments ago that says 420hc has JUST ENOUGH carbon to make it from iron to steel. That was kind of funny. 420j2 must be iron. He also says because the chromium is only 12-14 (well which is it? Haha) it's not very corrosion resistant. It's my understanding that 420hc is VERY corrosion resistant. 420j2 even more so. How did he get this information? I got the link if it's wanted. Not a huge deal but very misleading. Can someone provide any info on 420hc that prove or disprove these claims? It was on a buck 113 ranger review. Good review otherwise.
 
IIRC, 420HC has closer to .40% carbon, hence the "HC" designation.

Just out of curiosity, if you do not have the information to prove or disprove his claims, then how do you know his review is misleading? :confused:

Anyway, any steel chart should give one the correct percentages.

I'd say that his review is misleading but I wouldn't take it personally.

Indeed. And if I read something I find gratuitously wrong in someone's review, I don't take the rest of it seriously either.
 
Please search on your phone App finder "Knife Steel" you will find an app by Z Knives that lets you look up and compare the compositions of virtually any steel, cutlery or otherwise.
 
If they have common sence they won't rely on just one information source.
Who cares about the properties of the Steel anyways ? Just buy a buck knife and be happy.

Well, mild steel has ~0.29% or less carbon with as low as 0.05% carbon. Yes, 0.05% is enough carbon to form steel. For all but a handful of alloys, steel is almost entirely iron with a sprinkling of other elements. There are plenty of cutlery steels with a lower carbon content than even 1095. Sometimes it pays to read books to learn about a topic before making a review. Whoever did the review you're referencing sounds like another uninformed "reviewer" who would be better off reading rather than writing. A metallurgy or materials science textbook is a good place to start learning.

I'm taking this SO seriously. U have no idea how much I've been crying and throwing temper tantrums. I used a hooky title. Hoya us here right? Okay. I said what the reviewer said and I stated I laughed at the barely a steel thing WHICH SOUNDS SILLY. The corrosion resistance part is opposite of what I always heard. Your overreacting lol
 
I'd like an experts opinion. Sometimes you learn new things right? Well, I'd like to learn new things. I understand 420hc and steel in its entirety now? Lol Bye dude nice talking to you. Literally. Have no clue what's wrong.

Answers like this! I learned something new. Thank you.

paul bos heat treatment is really pretty decent. cant say the same about others as shown in the 2nd video i posted above. blade geometry also plays a roll.

I care because it's interesting. I also collect different types of wood. Not joking. Linden "basswood, silver and sugar maple. It's a weird obsession lol. I skin the bark off and everything. Each type of wood is "different" like steel

And I LOVE Buck!!! One of my favorites

And just like steel I try to find out what makes them different and why and what it can and can't do that others can or can't do. I'm weird I know lol
