The advantages
High-strength and ultra-high-strength alform® steels are thermomechanically rolled with accelerated cooling.
These special grades by voestalpine offer the following benefits:

Excellent cold formability


Edging radii smaller than those of standard steels of comparable strength
Excellent weldability

based on low carbon content and equivalents
 Amount of pre-heating either reduced or completely eliminated

Clean surface resulting from fine and homogeneous secondary
scale

Broad spectrum of steel grades and dimensions*

Yield strength of 700–1,100 MPa
 Thicknesses: 2.5 – 50 mm
 Widths: 900 – 3,000 mm
*Available dimensions per steel grade according to the current limit curves for hot-rolled strip and heavy plates

Hot-rolled strip and heavy plates
voestalpine produces and sells high-strength alform® steels as
 Hot-rolled steel strip
 Hot-rolled cut plates
 Heavy plates
A variety of production routes lead to specific product advantages.
Heavy plates are characterized as plate in the steel grade designation.
Hot-strip
rolling mill
Heavy plate
rolling stand

Effects and final results
Effects
 Dilution or alloying of weld metal composition with base metal
Manufacturers of filler metals only analyze properties of the pure,
unalloyed weld metal.
Final result
 Adapted filler metals (massive wires, metal flux cored wires) under
consideration of mixture with alform base material for extension of the
welding range and utilization of the full base metal potential

Drying of the edges is recommended at 80°C directly before welding.
2)
For complex welded structures (such as out-of-position welds, high number of weld seams,...), pre-heating according to EN 1011-2 is recommended.
3)
It is recommended that the interpass temperature be set so that the maximum measured t8/5 time is not exceeded.

High-strength and ultra-high-strength heavy plates
High-strength heavy plates are offered as fine-grained steels with a
minimum yield strength of 700 MPa. Ultra-high-strength heavy plates are
offered as voestalpine special grades at 960 MPa:

alform plate 700 M - - thermomechanically rolled high-strength finegrained steel in thicknesses between 8 and 50 mm

alform plate 960 M x-treme - thermomechanically rolled highstrength fine-grained steel in thicknesses between 8 and 15 mm

aldur 700 Q, QL, QL1 - quenched and tempered high-strength finegrained steel in thicknesses between 51 and 100 mm

alform welding system
Thermomechanically rolled heavy plates

alform®-heavy plates are manufactured through thermomechanical
rolling with accelerated cooling directly following the rolling process. A
quenching and tempering process is not necessary in the quencher and
the heat treating furnace.

These steels are characterized by very low carbon
content and a very fine-grained and homogeneous
structure. This results in the following:




High strength and excellent toughness
Best weldability based on low C equivalent
Good formability
Clean surface resulting from thin scale layer

Drying of the edges is recommended at 60°C directly before welding, see also Technical Terms of Delivery of voestalpine Grobblech GmbH.
Pre-heating according to EN 11001-2 is recommended for complex welded structures (such as out-of-position welds, high number of weld seams,...),
depending on sheet thickness and H2 consumption.
An interpass temperature below 150 °C is recommended for special requirements in strength and stiffness of the weld metal and in the weld joint
