Stainless Steel
Stainless Steel specifications held in the austenitic, martensitic and precipitation hardening varieties. Stocks are held in British Standard and International standards. Below is listed our most commonly supplied grades; please contact our sales office. Also stock is 301 stainless spring temper rolled strip.
Hi-Steel HSLA-80
Hi - Speed, high Speed Steel Tool Steel (made) : highly processed into the Tool Steel, carbon content high, while containing cr quantity is low (about 4%), reason burnish of Steel surface gloss darker, after heat can reach by HRc62 high hardness, resistance to rust performance not on a roll.
Mould Steel
Steel mould and Steel mould suppliers, global delivery, stock supply Steel mould steels.
Heat Resistant Steel
Heat resistant steel. AS Orlov Izobret. Mashinostr. 3, 48-49, 7/2000. The purpose of this work was to increase plasticity of heat resistant steel after aging at the 500-1300 deg C temperature and to improve its operational reliability.
Tool Steel
Comprehensive stocks held of tool steel, including hot work, cold work and plastic mould tool steel specifications. Below we detail our most common grades. Other British Standard and international special steels and tool steels are also available, please contact our sales office.
Ball Bearing Steel
Supplies Ball bearing steel of all types, along with carbon steel and specialty balls, to OEM's around the world. Also offers platinum balls, brass balls, gold, titanium, aluminum, carbon and plastic balls.
Spring Steel
Carbon spring steel is held in a wide range of sizes. Detailed below are our most common specifications. Carbon steel strip and spring steel sheet is available most commonly in the hardened and tempered condition, though certain sizes are available in the annealed condition. Round and flat bar is stocked in the as rolled condition. Most spring steel specifications are held to British Standard steel specifications including BS1449 & BS970.
Alloy and Carbon Steel
Alloy steel is steel alloyed with a variety of elements in total amounts of between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low alloy steels and high alloy steels. The difference between the two is somewhat arbitrary: Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0 %.[1][2] Most commonly, the phrase "alloy steel" refers to "low alloy" steels.

Home » Ruukki joins Cleantech with aim of developing more energy efficient products
Ruukki announced that it has joined Cleantech Finland, which represents clean technology companies. Ruukki's membership supports the company's goal to develop increasingly more energy efficient products and solutions for its customers.
Growing interest in green technology is reflected in Ruukki's business, especially in construction, the lifting, handling and transportation equipment industry and in the wind power industry.
Mr Toni Hemminki VP Energy and Environment at Ruukki said that "We are aiming at outstanding energy efficiency for our products. For the customer, this means innovations, light structures, lower energy costs and reduced emissions. There is a clear demand for new green technology products in many of our market areas and Cleantech Finland makes Finnish expertise on this front internationally known."
In construction, Ruukki has enhanced air tightness, especially in exterior wall products. This is a cost effective way to improve energy efficiency in new buildings. The environmental impacts of construction products are increasingly being rated according to international environmental classifications.
In addition, Ruukki is currently developing ground source heat solutions integrated into steel piles and solar power solutions integrated into façade claddings. Ruukki is also currently developing a new type of wind power tower structure, for example. The tower can be up to 160 meters high to benefit from better wind conditions higher up. The tower enables increased power generation and is well-suited to power production also inland.
Ruukki's special steel products improve product material efficiency, lighten product weight and enable structures with a longer useful life or higher load bearing capacity. New applications are continuously being identified for special steel products. One such application is the wall panels delivered for French trains. Use of Optim special steel has resulted in a significant reduction in the weight of these panels.
The Cleantech Finland project aims at supporting internationalization and growth within the Finnish clean technology sector. A large number of leading Finnish companies and specialist organizations are involved in the project.
