I'm somewhat of a weight wienie. Go ahead... lecture me all you want but don't expect me to take heed.
The story- I build my own forks and am always looking for solutions to reduce weight whenever possible. The last steel fork I did come in at 604g (650c). 700c forks are about 640-650g depending. The carbon forks I have (1" alloy steerer) are in the 450g neighborhood. I much prefer the appearance of steel forks, and inexpensive carbon forks with 1" alloy steerers are getting harder to come by.
The solution- Rather than use the 2mm wall thickness cromo steerer, utilize a 4130- 1" x .049" (1.2mm) tube. In a 250mm length the weight savings would be about 150g. That puts the completed weight right close to the carbon forks I have, and that is acceptable. Pretty inexpensive way to shed 150 grams.
The question- I'm not looking for warnings cuz I'm gonna do it anyway. What I want to know is, if you've done this did it work, or fail?
This is strictly for my own bikes so if there is a risk I don't care. It won't be catastrophic anyway, so what? C'mon let's hear it- how else are you gonna get a 450g steel fork?
