Principle of Duplex Stainless Steel - TubingChina

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.

Stainless Steel Manufacturing Processes – IspatGuru

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

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.
