Stainless steels require care dur- ing fabrication (5, 6). Their properties can vary depending on prior thermal and mechanical operation. Austenitic stainless steels are almost always placed in service in the annealed condition. This means they are quenched in water or other fast cooling media from the annealing temperature (1040°C -1130°C). In September 2010, to adapt the requirement of increasing overseas metallurgy market, approved by State-owned Assets Supervision and Administration Commission of the State Council (SASAC), Mirach Metallurgy Co., Limited was registered as a full exclusive subsidiary corporation for the international marketing activities of aluminium, stainless steel and tinplate. Welding stainless steel can reduce the corrosion resistance of the metal because of phase transformations occurring at elevated temperature. The two major detrimental phases that form at elevated temperature are chrome carbides and the intermetallic phase named sigma. These transformations occur roughly between 800⁰F and 1600⁰F. Stainless steel is the name given to a group of corrosion resistant and high temperature steels. Their remarkable resistance to corrosion is due to a chromium-rich oxide film which forms on the surface. When ordinary carbon steel is exposed to rain water, for example, it corrodes forming a brown iron oxide, commonly called rust, on the surface. 304 stainless steel is the most common commercial-grade alloy. It is also known as 18/8 because it contains around 18% chromium and 8% nickel. 430 stainless steel is less expensive because it does not contain nickel. These two alloys are chosen for grills and barbeques for a few reasons. They both are food-safe because of their corrosion. The first generation of duplex stainless steel (453S) was developed over 90 years ago. Figure 2 illustrates the issue that arises during welding due to the increased proportion of ferrite. Figure 2 - The phase balance after welding 453S. The situation improved with the second generation of duplex stainless steels such as 2205 - see Figure 3. Ferritic steel is commonly used in washing machines, boilers and indoor architecture. "Stainless" steel is actually a generic term referring to a variety of steel types.

Summary: Metallurgical Technologies, Inc. (MTi) received five stainless steel bolts from a marine environment. The bolts exhibited corrosion predominantly on the head of the bolt around the set screw, underneath the head of the bolt, and in the threads. MTi was requested to determine the cause of the corrosion. Ferritic steel is commonly used in washing machines, boilers and indoor architecture. "Stainless" steel is actually a generic term referring to a variety of steel types. Like all other kinds of steel, stainless steel is made primarily from iron and carbon in a two-step process. What makes stainless steel different is the addition of. Stainless Steel vs. Non-Stainless Steel. The Iron Age began between 5 and 6,000 years ago. The change from iron to steel is lost in time. We know that reliably produced high carbon steel was not possible until somewhere in the past 200 years. Steel was soft until it got to the point where blade smiths were producing high carbon steel. AISI 304 Stainless Steel (UNS S30400, SS 304) AISI 304 stainless steel (UNS S30400) is the most widely used stainless steel, containing 18-20% Cr and 8-10.5% Ni, and also known as 18-8 stainless steel.SS 304 is non-magnetic. 430 stainless steel is considered easily machineable as compared to 300 series of Stainless steel. The reason for easy machining is high elastic modulus. High elastic modulus material does not stretch or bend easily, resulting in better machining. Elastic modulus is a term that describes deformation in the material in response to force applied.
