Columbus Stainless, founded in 1966 and part of the Multinational Acerinox Group, is proud to be the only producer of stainless steel on the African Continent. Durable and 100% recyclable, stainless steel has boundless potential as the preferred metal for the future, and Columbus remains dedicated to playing a significant role in South Africas growth and development.To remain one of the top
Corrosion of metalsCorrosion of metals Introduction To ensure long and troublefree operation in a media it is of utmost importance to have knowledge about corrosion and the effect it can have on the product and the system in the operating environment. Various forms of corrosion on metals and their characteristics are lined below. Austenitic stainless
(1) Ferritic stainless steel:It is that steel when properly heat treated and finished, resists oxidation and corrosive attacks from corrosive media. Ferritic stainless steels contain 1218% chromium, 0.15 to 0.2% carbon besides iron and usual amounts of manganese and silicon. The steels are stainless and relatively cheap. They are magnetic in nature.
Introduction to the ASTM Designation System ::Total Example 2 - ASTM A 276-03, Type 304, 316, 410 Stainless and Heat Resisting Steel Bars and Shapes:Types 304, 316, 410 and others are based on the SAE designation system for stainless steels (see SAE and former AISI description that follows).

The ability of the oxide layer to heal itself means that the steel is corrosion resistant, no matter how much of the surface is removed. This is not the case when carbon or low alloy steels are protected from corrosion by metallic coatings such as zinc or cadmium or by organiStainless Steel Metal Casting ResourcesStainless steel is the common name for a large group of ferrous alloys that are resistant to rust. Unlike other iron alloys, stainless steel has a stable passivation layer that protects it from air and moisture. This rust-resistance makes it a good choice for many applications, including outdoor, aqueous, food service, and high-temperature uses.
Stainless Steels:An Introduction and Their Recent Developments explains issues related to surface treatment, grain refinement, coloration, defect detection and powder metallurgy of stainless
Stainless steel an introduction and their recent Stainless steel (SS) is an iron-chromium (Fe-Cr) alloy that is normally used in the food industry as it does not react with food and is resistant to corrosion (Lai, 2012). SS has three
Welding Metallurgy - an overview ScienceDirect Topics8.1 Introduction. Welding metallurgy has played a key role in the alloy development of duplex stainless steels. The earliest grades had high carbon contents and tended to form a ferrite-rich heat affected zone (HAZ). Although some austenite reformation occurred due to these high carbon levels, this also led to carbide precipitation and a loss in intergranular corrosion (IGC) resistance.
Feb 18, 2014 · Stainless steel is 100% recyclable and therefore a huge amount of stainless steel must be evaluated at the scrap yard. Handheld XRF analyzers bring immense value to scrap metal recyclers because it is a highly accurate, nondestructive testing technique that can analyze a metal sample in seconds with little to no need for sample preparation.
What Is the Metallurgy Term Known as Tempering?May 12, 2018 · Ryan Wojes wrote about commodities and metals for The Balance and worked as a metallurgist for more than 13 years. our editorial process mild steel and medium carbon steel lack enough carbon to alter their crystalline makeup, so they cannot be toughened and tempered. The Characteristics of Austenitic Stainless Steel. An Introduction to Introduction to Stainless Steel Grades, Properties and May 20, 2005 · Stainless steel is not a single material but the name for a family of corrosion resistant steels. Like many scientific discoveries the origins of stainless steel lies in a serendipitous accident. In 1913 Sheffield, England, Harry Brearley was investigating the development of new steel alloys for use in gun barrels. Stainless Steel Grades Explained
