Principle of Duplex Stainless Steel. The idea of duplex stainless steel dates back to the 1920s with the first cast being made at Avesta in Sweden in 1930. However, it is only in the last 30 years that duplex steel have begun to "take off" in a significant way. This is mainly due to advances in steelmaking techniques particularly with respect to control of nitrogen content.
May 04, 2014· General principles of producing stainless steels. Stainless steel decarburization must minimize the oxidation of chromium. It is generally accepted that when oxygen is injected into stainless steel, a mixture of chromium and iron is oxidized. Decarburization occurs when dissolved carbon reduces the chromium and iron oxides that form.
General Principles of Machining Stainless Steel The most common and most frequently machined stainless steel are the austenitic stainless steel types, such as grades 304/304L/304H and 316/316L.These are characterised by their high work hardening rates and poor chip breaking properties during machining.This article covers the important issues that influence the successful machining of these steel.
Stainless Steel Welding Characteristics By definition, stainless steels are iron-base alloys containing 10% or more chromium, which imparts to the metal the corrosion-resistant properties for which stainless steels are so highly regarded. The chromium content may be increased and other alloying elements added or adjusted to meet specific end-
Ferritic stainless steel is a flexible grade of the stainless steel family with properties closely matching those of the more popular and expensive austenitic grade. Yet, it is grossly underspecified for application because it is erroneously considered inferior to the austenitic.
THE FORMING POTENTIAL OF STAINLESS STEEL About stainless steels Stainless steels are iron alloys with a mini-mum chromium content of 10.5% (by weight) and a maximum of 1.2% carbon, necessary to ensure the build-up of a self-healing oxide layer – known as the passive layer – which provides the alloy's corrosion resistance.
Also known as "marine grade" stainless steel due to its increased resistance to chloride corrosion compared to type 304. SS316 is often used for building nuclear reprocessing plants. Most watches that are made of stainless steel are made of this grade.

Jan 17, 2011· However, an item of 316 stainless steel which has significant welding or machining may be sufficiently magnetic to produce a noticeable attraction when brought near a magnet. "Ferrite free" welding rods are available to minimize the tendency of welds to become magnetic. In principle, a welded or machined component can be annealed to restore it ...
Steel industry sustainability principles. The member companies of worldsteel are committed to a vision where steel is valued as a major foundation of a sustainable world. This is achieved by a financially sound industry that takes leadership in environmental, social and economic sustainability.
Stainless steel is more expensive than standard grades of steel but it has greater resistance to corrosion, needs low maintenance and has no need for painting or other protective coatings. These factors mean stainless steel can be more economically …

The SAE steel grades system is a standard alloy numbering system for steel grades maintained by SAE International.. In the 1930's and 1940's, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels. These efforts were similar and overlapped significantly. For several decades the systems were united into a joint system ...

Because most stainless steel products received from the producing mill have been pickled, descaling is required only as a result of subsequent manufacturing operations. In evaluating the different methods for removing scale, it is well to keep in mind that scale on stainless steel is far more complex than scale formed on plain mild steel.

General principles for selection of stainless steels. Stainless steels are defined as iron alloys with a minimum of 10.5% chromium. Other alloying elements are added to enhance their structure and properties, but fundamentally, stainless steels are considered for selection as steels with corrosion resistant properties.
Steel - Steel - Primary steelmaking: In principle, steelmaking is a melting, purifying, and alloying process carried out at approximately 1,600° C (2,900° F) in molten conditions. Various chemical reactions are initiated, either in sequence or simultaneously, in order to arrive at specified chemical compositions and temperatures.
Jun 08, 2010· Advantages of rod drawing are that drawing speeds are relatively high and high area reductions (approximately 45 percent for stainless steel) are possible. Disadvantages are that it is a two-person operation and it requires an additional drawing operation, such as a plug draw or sinking, to remove the spiral pattern. Plug Drawing.
