What do you know of Dedacciai Zero tubing?

Sep 12, 2011 · How would you guys compare the Zero Tre with the original Columbus SL? About the same level? Thanks! It's not what kind of steel is used but which tube is used - if it has the proper butting profile for the task, correct diameter, wall profiles - ect. 0/3 and 0/2 tubes work very well for MTB's, I use a few of them. Zero is the lightest offering columbus 25crmo4 steelTubing Materials - Framebuilding25CrMo4 Steel The chemical composition of this steel, specifying a higher percentage of Chromium, gives the material good resistance properties to overheating. The formation of carbides prevents the grain enlargement: the steel maintains its properties during brazingTIG Welding Chrome-Moly Tubing - lincolnelectricOther stainless steel fillers can cause cracking. Stainless filler material is typically more expensive. Q. Do I need to heat treat (stress relieve) 4130 after welding? A. Thin wall tubing normally does not require stress relief. For parts thicker than .120", stress-relieving is recommended and 1,100ºF is the optimum temperature for tubing columbus 25crmo4 steel

Makes extremely strong, low columbus 25crmo4 steelMaking sense of 4130 in frame building KuromoriThin wall tubes of 25crmo4 cycle tubing (marked SL, different from modern production Columbus SL) were shown by Emiliani (1983) to increase in tensile strength when heated to brass brazing temperatures of 1700F (927C) for 5 minutes compared to the steel as delivered, as well as at 1500F (816C) which is at the upper end of the intercritical range.Is 4130 seamless tubing dent resistant?Not only is the tubing stronger, but harder making it dent resistant. Same set as RCX2 above but oversized maintaining low weight and increasing strength and stiffness. A conventional 4130 seamless Chromoly stress relieved to improve the mechanical strength 7% over tubing that is not stress relieved.See all results for this question

Is 4130 chrome-moly TIG welded?

Yes, 4130 Chrome-Moly has been TIG welded in the aerospace and aircraft industries for years. As with all welding, proper procedures and techniques must be followed. Q. Do I need to pre-heat? A. Thin wall tubing (< 0.120" wall) applications do not typically require the normal 300ºF to 400ºF pre-heat to obtain acceptable results.See all results for this questionHistory ColumbusCurrently, Columbus is the leading manufactured of high-precision steel tubes, and also offering a growing range of new-generation bicycle carbon forks.
