In order to confer stainless properties, chromium must be present in amounts above 11.5% but, with this as a primary requirement, the steels can also contain nickel, manganese, molybdenum, etc. Some of the steels have been standardized, others are produced on a proprietary basis. For the ...
(50%) phases in their microstructure which provide improved corrosion resistance. These alloys contain relatively high amounts of chromium with only enough nickel and austenizers to develop 50% austenite[83]. The duplexstainless steelscontain molybdenum as an alloying ingredient that is responsible ...
A.18/8 stainless steel is nominally 18% chromium and 8% nickel, with the remainder being mainly iron; it does however also contain other elements, but at very low levels. It is also known as 302 or 304 grade stainless steel. This grade of stainless is generally regarded as one of the ...
摘要: In 1994, a study of nickel release and allergic contact dermatitis from nickel-plated metals and stainless steels was published in this journal. It was shown that low-sulfur stainless steel grades like AISI 304, 316L or 430 (S 0.1%) should be avoided.关键词:...
Stainless steel is a wide used material, containing at least 10.5% of Chromium, and other elements added to form stainless steel structure, these elements have Carbon, Silicon, Manganese, Phosphorus, Sulfur, Nickel, Molybdenum, Titanium and Copper, it is noted as high strength and excellent corro...

Nickel can cause allergic reactions to human beings. In the last several years the need of nickel free stainless steels for applications at and in the human body has become more and more urgent. Such Ni-free steels have recently been developed at ETH Zurich. They are characterized by a full...

The idea is that if you add the right amount of nickel (something like 6%), the surface becomes slower to corrode (probably partially due to greater nobility and partially due to "tighter" corrosion products) -- but is still active enough to cathodically protect steel. Yes, hydrogen embrittl...
The alternative solution to prevent IGSCC is to use stabilized austenitic stainless steels such as SS321, SS347, and SS348. All these grades are versions of SS304. They contain carbide forming and stabilizing elements such as titanium, niobium, and tantalum, which form carbide in preference to...
