Update:
I have successfully formed 1010 material as shown in the above pictures.
If I wanted to increase the strength of the material and maintain the uniform elongation under elevated temperatures, am I better to to go with a higher carbon steel (1012,1014, etc.) or an HSLA (035,050, etc)...
Thanks for the advice. This process saves about 40% on material over existing product, I'm hoping that will offset the cost of the final product.
Do you think higher carbon such as 1014 1016 would allow me to keep the formability advantage (and cost?) over 950 and give me added strength on...
We have as close to uniform heat across the entire length of the leg as possible. Per video tape, there is no visible difference in color (ie heat) across the 2" heated area leg.
It wants to fracture at we assume is the hottest spot. More noticeable on the 950 than the 1010.
By "pre-drill"...
Attached are 2 pictures showing the tearing with and without heat.
Does the addition of heat make the HSLA elongation look more like that of 1010? In other words, I would think that heating the material will enhance the elongation of both materials?

The 1010 is galvanized and in coil form. no special handling or working of the material.
The reason that we can't do it at room temperature is the tearing action at the end of the strip that occurs. The force to tear is significantly lower than the yield strength of the steel strip in the area...
Thank you all for your responses,
We are trying to stretch a 2.5”long x 0.25”wide x .018”thk by 15%. Due to the direction of the forces, we are heating the center 2” of the 2.5” leg. The heat is only to reduce the yield strength in the area intended to stretch. If no heat is applied, the...
I have developed a product that requires warm forming to produce. How would I go about selecting the best steel chemistry for hot or warm forming (800 to 1400 deg f). This material would be used in high volume and reasonable cost. ie. not exotic. Any and all comments welcome.
