I Forge Iron

Forging stainless steel under the power hammer ?


Recommended Posts

While it looks cool, those scale cold laps can/will come loose and can cut someone. A quick stroke or two with a wire brush when it comes out of the fire to knock the scale off before it goes on the anvil usually takes care of driving scale into the work piece.

 

Leaving an as forged or hammer texture, heck any texture, should be a deliberate process rather than just what happens.

Thanks Frosty, so it looks like scale is what I've been thinking were "cracks" . I think I've had both, but the idea that not cleaning off before drawing out has caused what I thought were delamination ( and was in fact the opposite ). It's true that I was only banging the hot metal on the floor on my way to the hammer to let any loose scale drop off and not brushing it off. Thanks for the heads-up.

Hand made does not equal looking rough, just remember that Col.  It can and may well come back to bite you.

By the time I've finished with them,( cleaning, grinding, buffing ect ) there is nothing rough about them Phil, you couldn't cut your self on these if you wanted too. The look is very deliberate, and nothing is accidental about it.

Oh no, I was talking about when we get to Moonies next, I'm sure I will be able to bring up something about whatever you have forged and it must have been hand made cause I can see its rough.

Apparently I;m forbidden from swearing on hear or otherwise Phil #$%&*@#$#^%%$&# off

There's also a desire from folk of my generation for unique things. I remember as a kid riding in the station wagon with the folks one of our road games was to spot as many cars, houses and such that were just like ours. After WWII the enormous manufacturing powers the US had developed to fight the war had to do something so it started mass producing things folk wanted and needed.

 

For my folks, a couple depression era kids mass production meant goods they could afford and jobs to earn them, it was the very symbol of prosperity. I grew up with that prosperity and have always had a desire for something unique, whatever I had most of the kids I knew had one just like it.

 

Unfortunately for folk who don't have enough knowledge/experience to see details we wouldn't miss, they need something obvious so hammer marks have become a trademark for hand forged. For a huge segment of our market hand forged without hammer marks is like trying to sell Coca Cola in a green can.

Thanks for the vote of confidence Phil, I hope I can repay the compliment at some point  :P

Col I have no doubt that you will be able to repay the compliment, I have made more ash trays, bird baths, and letter boxes than you may think, (ashtrays bird baths and letter boxes are what all the ones that went wrong become) and experience has not made me any better at not making them.  My head hurts now, I think I'll have a cup of tea a bex and a good lie down.

Hope your lie down has you feeling better.

I had posted a more jovial response but the powers that be decided it was inappropriate and took it down. Anyway the final thing is without cold lap or any other thing that would or could hurt you as you can see ya big palooka.  :)

They look very dramatic...but the flame licks around the wooden post? How do you get away with that?

Going back to your OP problem, the splitting, cold shut and flakes, definitely working below red is a no no. You can feel the springiness and resilience under the power hammer but unfortunately by that time it is too late and it may well have sheared across the diagonal.

I have had the surface lift on 316L even when I had done very little work and certainly not below red. I went back to the parent bar and discovered there were a couple of flakes running along the length from the original rolling. This was from 50mm (2") square. Though I have also had some snags on some pickled and peeled 50mm (2") round which had been rolled into rings. Have a close look at your stock and maybe grind out any flakes prior to forging...much better than afterwards.

Posts above refer to using all your senses when forging stainless, but I always do that with every material and process, not sure how you turn a sense off actually.... However with all our sensory deprivatory safety gear I find it always useful if possible to cut each element double length in order to use one piece as a handle rather than accept the slightly distorted feedback you get from tongs.

welcome to the moderator queue buddy, i got on without even saying bad words!

glad you sorted it out with the stainless, as usual i got to the thread long after it was answered ;) , but still want to oFfer help (or jUst have a yarn) ....

stainless is for sure a CantanKerous beast> if'n YOU don't Treat her with all the reSpecT shE deserVEs

 

we had an apprentice +under me< where i didmy apprtenticeshipwho just couldn't get it in his head NOT to burn the any stainless we forged<, or work it cold!

never in the wright heat range!

 

he also used to go around writing "hot" with chalk on things as they cooled down, i said "it is a blacksmith shop!, assume everything is hot! you are better off writing COLD ont the cold stuff!!"

 

so when he forge stainless or high tensile cold, even the boss could hear it from the other end of the shop, while the offender was flogging on the unfortunate item, and yell "WRITE COLD ON IT!!!"
