What is stainless steel / SUS? Features of stainless steel

1. What is stainless steel / SUS? Features of stainless steel Stainless steel is an alloy steel containing iron (Fe) as the main component. According to expert Steel contain 1.2% or less carbon and 10.5% or more of chromium, according to the ISO standard of international regulations. It is a rapidly popularized material in recent years and is now used in many products. It seems that the reason for the rapid generalization is that the characteristics of stainless steel, such as strong corrosion resistance (rust), high workability, high heat resistance, and strong strength, have been widely accepted. It is often used outdoors because of its strong corrosion resistance. Stainless steel processing Let's take a closer look at corrosion resistance, heat resistance, strength, and workability property of steel. 1.Corrosion resistance This corrosion resistance is the most notable feature of stainless steel. The English name is stainless steel, and the original etymology is stainless, which means "does not rust." The corrosion resistance is excellent in that the additive chromium combines with oxygen to form a passivation film (oxide film) on the surface of the steel, which stops the progress of rust. It can be said that this chromium-free iron is relatively vulnerable to rust compared to SS 304 Pipe Fittings. 2.Heat-resistant Generally, the tensile strength of steel does not decrease much up to about 500 ° C. However, if the temperature rises above 500 ° C, the mechanical strength will drop. In particular, the strength of martensitic and ferritic stainless steels drops sharply above 500 ° C. Some types are improved by adding additive elements.

2. 3.Strength The strength also changes depending on the heat treatment and constituent elements. Generally, carbon is added to iron, so it is a material with higher strength than iron. Please refer to the next section for details. The austenitic stainless steel has a larger specific heat, coefficient of thermal expansion, and specific resistance than the martensitic and ferritic stainless steels. On the other hand, it is characteristic that the thermal conductivity is small. The stainless steel used for everything around us There are various uses for Duplex 2205 Sheet, especially those that use the "high corrosion resistance" feature of stainless steel. For example, it is used for roofing materials and handrails at construction sites. Familiar items are used for things that use water, such as washing machines, tableware, and sinks. It is also used in transportation equipment used outdoors, such as railroad cars and automobiles, and it can be said that it is a very familiar material to mention. Stainless Steel Sheet suppliers supply the best stainless steel. It is also used in precision equipment such as medical equipment and IT equipment because it has no magnetism, which is a characteristic of austenitic stainless steel. Titanium tube manufacturers in India manufactures the best titanium tube. There are also many other application in which stainless steel used. Hope you like this article as it provides you all the knowledge about the stainless steel. This will reallyprove beneficial toyou.
