Reference is often made to stainless steel in the singular sense as if it were one material. Actually there are over 50 stainless steel alloys. Three general classifications are used to identify stainless steels. They are: 1. Metallurgical Structure. 2. The AISI numbering system: namely 200, 300, and 400 Series numbers. 3.

Pickling and passivating stainless steel. This resource describes the surface treatments known as pickling and passivation that can be applied to stainless …
This is a batch process with a cycle time of about two to three hours. Since scrap metal is used instead of molten iron, no coke making or iron making operations are associated with steel production using an EAF. This technology results in the production of metal dusts, slag, and gaseous products.
It can be seen that blast furnace–BOF steelmaking route consumes 19.8–31.2 GJ energy per ton crude steel, while the EAF route using steel scrap consumes 9.1–12.5 GJ energy per ton steel.For the integrated steel production with blast furnace–BOF route, responsible for almost 2/3 of the total steel production, about 75% of the energy arising …
PRODUCTION OF STAINLESS STEELS For many years, stainless steels were both melted and refined in an electric arc furnace. These steps are now frequently separated, with the molten charge in the electric furnace transferred to a separate unit for adjusting of composition and removal of impurities.
With conventional gas nitriding, several cleaning processes – wet blasting, pickling and chemical reduction – have been developed to remove the oxide. With ion nitriding, however, this passive layer can be removed by sputtering with hydrogen in the vessel itself just prior to introducing the process gas.
Two different types of produced stainless steel have been included, namely Stainless 1 which is produced with an 80% recycle content and Stainless 2 which is produced with a 60% recycled content.
AISI 316L nitrided at 500°C (932°F) Advantages. Plasma nitriding exhibits a strong advantage relative to the conventional gas process for nitriding stainless steels. The chromium-oxide passive layer on the surface of these materials represents a barrier to nitriding and must be removed prior to nitriding.

Within this review, the manufacture of stainless steel is considered to include the stages of stainless steel production from melting through to finishing. Stainless steel production gives rise to a mixture of airborne dusts and fumes, and thus presents the potential for inhalation exposure in the occupational setting. The airborne dusts and
Production of Stainless Steel: Part One. Abstract: In the history of research and development of stainless steels, most important has been the decarburization of high chromium molten steel. Efficient decarburization …
More than a decade ago, the production of as little as 100kg/year of a monoclonal antibody, for example, might have necessitated the use of several large stainless-steel bioreactors and equivalently sized equipment.
The 316 grade is also used for drinking faucets as well as for kitchen and bath fixtures. The 316L grade is the most expensive grade of stainless steel used in the manufacturing of faucets. It is used for high-end faucets. 4. The manufacturing process. The stainless steel faucet production method includes the following basic process:
The results show that: the injection parts had no obvious cracks, burrs and defects such as holes, good shape, smooth surface under 304L stainless steel powder system in the temperature of 185 °C ...
A range of filter types and sizes are used in different areas. For example, in upstream processing suites, both hydrophobic and hydrophilic filters can be used. Hydrophobic filters act as vent filters for …
Today, one 2,000-L single-use bioreactor can produce the same titers that a 20,000-L stainless-steel bioreactor could accomplish just a few years ago ( 1, 5 ). Rocking Motion: The first single-use bioreactor was launched in 1996 by Wave Biotechnology ( 5 ). It consisted of a pillow-shaped disposable bag that inflated to sustain a rigid structure.

A steel of high importance especially for industries with high hygiene standards such as medical and nutrition production is the stainless steel X5CrNi18-10 (1.4301).
Both pickling and passivation are chemical treatments applied to the surface of stainless steel to remove contaminants and assist the formation of a continuous chromium-oxide, passive film. Pickling and passivation are both acid treatments and neither will remove grease or oil. If the fabrication is dirty, it may be neccesary to use a detergent ...
This guide will focus on three common stainless steel fabricating processes: work hardening, machining, and welding. Work Hardening with Stainless Steel Work hardening is the process of strengthening material through deformation.
Steel production from scrap requires around one-eighth of the energy of that produced from iron ore – mainly in the form of electricity, rather than coal for production from iron ore. This benefit results in high recycling rates (around 80-90% globally).
This article describes the machinery and methods used in fabricating or altering stainless steel for production needs, including welding, machining, and work …
Sheet metal fabrication is a non-additive, non-subtractive process. It begins with flat material and, by definition, maintains constant material thickness throughout a part. In some cases, areas of a part can be selectively thickened by welding multiple metal sheets together, but this is a costly and uncommon practice.
