AISI 316 Stainless Steel (UNS S31600) AISI 316 stainless steel (UNS S31600) is the second most commonly used austenitic stainless steel. Due to the addition of Molybdenum (Mo), SS 316 has a great improvement in corrosion resistance and certain properties compared to SS304.

Ferritic steel grades 4713 and 4724 are best suited for temperatures between 550°C and 850°C. The higher alloyed 4736, 4742, 4762 grades can be applied at temperatures up to 1150°C showing excellent resistance against reducing sulphur attacks and molten metals. Due to their ferritic structure, the ferritic steels show lower strength at ...

In the black curve (the area without inclusions), the passive state of the stainless steel was observed until 0.8 V. The slight increase in current density at approximately 0.8 V was attributed to ...

Since the 1980s, vacuum hot rolling has been developed to fabricate the stainless steel clad plates by the Iron and Steel Institute of Japan. Herein, hot rolling is a widely used solid-state bonding process …

Copper nickel alloys, also known as CuNi or cupronickel alloys, are a group of alloys consisting primarily of copper and nickel, with small amounts of other elements added to enhance such properties as: strength, corrosion resistance, hardenability, weldability, and castability. The most common types of CuNi alloys are the 90/10 and …

AISI 303 stainless steel (UNS S30300) was developed for easy cutting and basically belongs to 18-8 stainless steel. It improves the cutting performance while maintaining good mechanical properties.

The chromium in stainless steels is primarily responsible for the self-passivation mechanism. In contrast to carbon or low alloy steels, stainless steels must have a minimum chromium content of 10.5% (by weight) of chromium (and a maximum of 1.2% carbon). This is the definition of stainless steels given in EN 10088-1.

Solution (By Examveda Team) Stainless steel is an alloy of Iron with a minimum of 10.5% Chromium. Chromium produces a thin layer of oxide on the surface of the steel known as the 'passive layer'. This prevents any further corrosion of the surface. Increasing the amount of Chromium gives an increased resistance to corrosion.
