#18 8 stainless steel definition series#

Martensitic alloy series formed by precipitation hardening.Ī duplex (both ferric and austenitic) alloy with excellent strength and corrosion resistance.Īn alloy similar to type 2205 in all respects except for a lower molybdenum content, leading to reduced pitted corrosion resistance. 304 Stainless steel is an austenitic steel alloy that is part of the 18-8 family. This series contains some of the cheapest stainless steel, used for car exhausts, some higher grade cutlery steel, and some of the hardest stainless steel, used for replica swords and knives. This series of stainless steel is used for food utensils and surgical scrub sinks and instruments.įerritic and martensitic chromium alloy series. The presence of these elements plays a crucial role in defining the properties and characteristics of stainless steel. The ratio 18/8 refers to the composition of the alloy, with 18 chromium and 8 nickel content. Contains the most popular grade of stainless steel, grade 304. 18/8 stainless steel is a commonly used alloy that finds its application in various industries. The structure of the material grade designation AISI 430 - Cr (1618 ) C (0.08 ) AISI 304 - Cr (18 ) Ni (10 ) C (0.05 ) AISI 304L - (Low Carbon): Cr (18. It is a free-machining grade and is a modified version of the necessary 18 chromium / 8 nickel stainless. Note that some of the types of stainless steel are described as 'austenitic', meaning that they are composed of the gamma allotrope of iron:Īn austenitic, general purpose stainless steel widely used in furniture.Īustenitic chromium-nickel-manganese alloy series used for general purpose metalwork.Īustenitic chromium-nickel alloy series. However, it cannot be hardened by heat treatment. Stainless steel has its own list of classifications, each of which will be explained in outline below. In order to assis t the reader in this selection, Euro Inox makes the following tables of technical properties available. Since steel can be alloyed with an infinite number of combinations of alloying elements, a classification system has been developed to facilitate easy identification of the compounds used. The selection of the appropriate stainless steel grade for each applic ation is the result of variou s considerations.
