Bainite in Steel (98%wtFe)Stronger than Titanium-6Al-4V STA Bar at same Ductility

Flash Bainite is the Strongest, Most Ductile, Lean Alloyed, Readily Weldable, Least Expensive Maximum Strength Steel known to mankind.  Strength ranges from 1100 to 2080MPa with 8 to 9% elongation.  Total elongation up to 10-11% is not uncommon.  In AISI4130 at 1900MPa and 9% elongation, Flash Bainite overcomes the benefit of lighter 1040MPa HS Ti-64 STA Bar because Flash 4130's strength is 87% superior on a per mass basis.

Common off the shelf steel sheet, plate, and tubing can be transformed to Flash Bainite. Through rapid heating and water quench, a bainitic microstructure is made in a thermal cycle of just a few seconds (ambient/austenize /quench/ambient) in a continuous rolling process.

Environmentally friendly, this process consumes only a Kwatt of energy per Kg of steel processed. Water is used instead of polluting oils or molten salt. Traditional Time Temperature Transformation and Continuous Cooling Curves do not apply to common steels transformed with this process. Isothermal holding or continuous cooling is not required. Bainite can now be controllably Flash formed in times never before possible to create Bainitic High Strength Steel (BHSS).
No costly alloying is needed to achieve this highly sought after bainitic microstucture. Advanced High Strength Steel no longer needs to rely on a fully martensitic phase to achieve the yield strengths demanded by today's engineers. Tensile strengths of 1600MPa at 8.7% elongation are obtained from common AISI 1020 steel. Flash Processed AISI1010 has 1100MPa tensile strength and 8.0% elongation.  As a temper resistant microstructure, Flash Bainite's properties can be far superior to martensitic steels.  While two to four times more ductile in forming operations, Flash Bainite's microstructural based strength is not as significantly degraded by an inherently weak Heat Affected Zone (HAZ) after welding operations.

To reduce part mass, this is believed to be the first continuous rolling process with the ability to create variable thicknesses and patterns of different microstructures in a single stamping blank.  Localized strength, toughness, and form-ability can now easily be micro-patterned in different areas of a single piece of sheet steel that will be formed in a stamping press, or by other pressure forming means.

Flash Bainite Armor is superior to RHA and High Hard.  Flash4130, the leanest High Hard ever, offers a 33% mass reduction over RHA for AP at 0d obliquity and even better performance against High Hard.

Bainite should be the standard, not the specialty steel it is now. This patent pending process may soon be the leading operation for most all high strength steel production.  For those authoritative metallurgists serious about shaping the new future of bainite, contact us for opportunites using this process as the baseline heat treatment for your new Bainitic High Strength Steel.
