AUSTEK, 100% 300

2008 New Arrival, Revolution In SUS 300 Series Penerate

No More Suffer In The Rust, AUSTEK, 100% 300 Series Slove It !

"Unique " & The No 1 Drilling Ability

All stainless made of SUS 300 series (302,304,305,316), " No Carbonization". The invention patent of the world. Heating causing the stainless steel to loose its properties, the chemical compounds will be the same but the carbon will come out and cause rust. True-Stan remains unchanged but is much harder for penetration. The best choice to eliminate red rust, high anti-corrosion, specified worldwide in all the applications of interior or outdoor.

Steel Plate Thickness:  2mm or 1.5mm x 2

Recommended Screwgun: 1000 RPM

Specification:

Finish: Electro Zinc Plated & Wax

Corrosion Test: 500 HRS Per ASTM B-117

Kesternich Test: 15 Cycles Per DIN50018


SCBM is a new and pending patent. It totally overturns the traditional welding processing originally, most stainless that is "hardened" has to be treated as to welded. However, "SCBM" is without carbonization, the original properties of the stainless remain 100% intact, but the genuine "cold-forged", the failure rate is approximately under 1%.
