Steel and raw materials

contributing factors include high material efficiency rates, co-product recycling and steel recycling. • Steelmaking is nearing zero-waste, with current material efficiency rates at 97.5%. This means that over 97% of raw materials used on-site are converted to products and co-products that are used or recycled.15

An Introduction to Nitriding - ASM International

Fry then investigated the effects of alloying elements on surface hard-ness. He discovered that the nitriding process produced a high surface hardness only on steels containing chromium, molybdenum, aluminum, 4/Practical Nitriding and Ferritic Nitrocarburizing Fig. 2 Schematic of a typical nitrided case structure Compound zone, dual phase

alloying elements may be specified. †3xx.x: Alloys in which silicon is the principal alloying element. The other alloying elements such as copper and magnesium are specified. The 3xx.x series comprises nearly 90% of all shaped castings pro-duced. †4xx.x: Alloys in which silicon is the principal alloying element.

are called alloying elements. Adding the alloying elements may result in a change in the properties of the base metal. For example, pure aluminum is relatively soft and weak. However, adding small amounts or copper, manganese, and magnesium will increase aluminum's strength many times. Heat treatment can increase or decrease an alloy's strength ...

Guide to Nickel Aluminium Bronze for Engineers

Alloys of copper and aluminium are known as aluminium bronze and, together with other alloying additions, produce a range of properties that are beneficial to a diverse range of industries. Of these, the nickel aluminium bronze group of alloys is the most widely used.

The salt spray test and its use in ranking stainless steels

By adding various alloying elements it is possible to create a complete range of grades, which have different physical or chemical properties. The choice of grade must take into account several different parameters. Corrosion resistance will be one of them. While this parameter is essential, the choice remains very difficult for
