Press Release New Arcoplate Mill

PERTH, AUSTRALIA--(Marketwire - August 18, 2009) - Mr. Gene Kostecki, Chairman and CEO of Alloy Steel International (OTCBB: AYSI), today announced that the new ARCOPLATE manufacturing plant, specifically designed to produce extra thick super alloy wear plate, has been successfully commissioned and has commenced production.

Alloy Steel's new production mill continues to lead the world in continuous cast fused alloy cladding and Mr. Kostecki advises that it is the only process in the world capable of producing a bi-metallic fused super alloy wear plate in a single pass in a thickness over 20mm or just over 3/4 of an inch in a single contentious casting operation.

The technology has major benefits in that this process eliminates locked-in stresses that are associated with the conventional weld overlay processes which have been used for over 60 years.

Alloy's other main advantage with this thicker super alloy material is that it makes it now possible to go head to head against other thick wear resistant steels and castings, some of which may be up to 6 inches or 150 mm thick with a 3/4 inch or 20mm material. Not only would Arcoplate be significantly cheaper for the client to purchase in the first place, but the real savings would come through in the form of much greater productivity by not having to stop production in order to change out worn wear liners more frequently.

Conventional weld overlay methods used to produce a hard surface weld overlay can only achieve a weld at best 1/4 inch or 6mm thick in a single pass and is therefore floored with major quality technical limitations.

These limitations are base metal dilution, uneven hardness, locked in stresses and underbead cracking.

Alloy Steel International's new technology has circumvented all the known technical difficulties to eliminate these limitations. To date, Alloy Steel International has not seen evidence of a single weld overlay manufacturer coming close to what was the company's initial 1/2 inch overlay in a single layer operation.

The most significant advantages of Alloy Steel's technology over the conventional weld overlay technology and general hard steel technology is that Alloy Steel's Arcoplate generally outlasts the weld overlay by an average of three to one in actual field tests, and with 500 Brinell hard steel plate up to thirty times have been reported.

To the company's knowledge, this is a significant technological breakthrough which should see Alloy Steel's new technology be specified more and more in new mining and mineral processing projects and in upgrades with existing mining and processing plants.

Alloy Steel International is very encouraged with the strong interest being shown by all the hard rock miners who have seen the new test samples and the technical reports which have been carried out by a number of independent laboratories on Alloys new thicker super alloy product.

According to Mr. Kostecki, "As markets are continuing to see pressure put on miners and processors it is absolutely crucial that our clients have the tools and materials available to them that will meet the challenges that they face in maintaining increased production while at the same time reducing production costs."
