Stainless Steel General The designation "stainless steel" is a general generic term for rust-proof steels. The chrome content in the steel is generally at least 12 %. This makes it resistant to oxidising corrosive agents. If the chrome alloy or other alloy components, such as Ni, Mo, Ti or Niob, are increased, the resistance to corrosion is also improved. Sulphur as an alloy component improves the machinability but increases the susceptibility to cracking and the addition of nitrogen improves the mechanical properties. Titanium and niobium are important alloy components for the prevention of...

Roughness General Stainless steels are harmless when used as a standard material in the food and beverage industry, both physiologically and with regard to taste. In addition to the correct selection of material, the properties of the surface which comes into contact with the product during the manufacturing and transportation of food products are crucial. As well as resistance to pitting, the adhesion of microorganisms, product residue and covering, the structure of crusts and the cleaning performance all depend on the surface quality of the material. The average roughness Ra of the roughness...

DIN EN 10217-7 General DIN EN 10217-7 (DIN purchased from Beuth Verlag GmbH, 10722 Berlin) describes the technical delivery conditions for "Welded steel tubes for pressure purposes". The calculation value for the welded seam is set at 1.0 in this standard. The pipes described in this way are essentially used in pressure vessel engineering, apparatus engineering and pipeline engineering. As well as the assessment criteria for the supplied goods, the DIN standard also describes - the manufacturing method - the delivery condition - the chemical compositions - mechanical and technological properties...
