Do you know why a tiny pebble will drop to the bottom of a glass of water, while a giant log will float on the surface of a river? Density. The pebble is more dense than the water while the tree is less dense. Like the pebble, steel is also more dense than water, but ships crafted from tons of stainless steel plate carry cargo and passengers on top of the ocean all the time. How does density explain that?

When metals exposed to a high enough temperature, the melting point, it will melt. When subjected to high heat that doesn’t reach the melting point, it also will soften. Beacause soft metals are more malleable, artisans or metal workers can bend them into beautiful or useful shapes. All metal does not have the same melting point. Not even all grades of the same metal will melt at the same temperature. Let’s talk specifically about stainless steel’s melting point.

Like other forms of steel, stainless steel is an alloy of iron and carbon. What distinguishes is the stainless steel is must contain at least 10% chromium by weight. The chromium gives stainless steel its non-corrosive characteristics, which help lengthen the metal’s lifespan. Stainless steel comes in many different grade, each grade brings its own unique chemical composition, tensile strength, and other characteristics. Let’s compare the two most popular grades of stainless steel—430 and 304.

Stainless steel is widely recognized for its strength and its anti-corrosive properties. Besides, they are also aesthetically dependable and thus popular, uasally appears in kitchen accessories, surgical tools, auto bodies, and sculptures. Like other forms of steel, not all stainless steel is the same, stainless steel comes in a variety of grades. 303 and 304 stainless steel are two popular stainless steel grades. What is the distinctions between stainless steel 303 and 304? Let’s take a closer look and compare.

We see stainless steel all the timein our life, people may have doubts who are not familiar with the stainless steel hot rolling and cold rolling process. What are stainless steel cold rolling and hot rolling? What's the difference between the two technologies? They are steel or steel plate forming processes,which have a greatinfluence on the structure and properties of steel.Hot rolling is the main type of steel rolling,small section steel and thin plate are mainly produced bycold rolling. There are some contrasts on cold rolling and hot rolling, such as advantages, disadvantages, features and so on:

The properties and organization of stainless steel are mainly determined by various elements. At present, there are more than 100 known chemical elements, and the elements that have the greatest impact on the properties and structure of stainless steel are: carbon, chromium, nickel, manganese, nitrogen, titanium, niobium, molybdenum, copper, aluminum, silicon, vanadium, tungsten , boron and more than ten kinds. Due to the addition of these elements, the internal structure of the steel changes, so that the steel has special properties. The effects of various elements on the properties and structure of stainless steel are as follows.

Cutting technology is often used in processing stainless steel, and there are many types of cutting technology. They are divided into stainless steel laser cutting, water cutting, plasma cutting and wire cutting. Do you know all four cutting processes of stainless steel?

Stainless steel is mainly famous for its corrosion resistance and oxidation resistance. It is used in all walks of life. Different grades make it suitable for different fields. What Factors Should be Considered When Selecting Stainless Steel Grade?

Stainless steel is a kind of steel with resistance to weak corrosive media such as air, steam and water or rust resistance. The steel resistant to chemical corrosive media (acid, alkali and salt) is called acid resistant steel, which is mainly characterized by rust resistance, corrosion resistance and antibacterial property, with chromium content of at least 10.5% and carbon content of no more than 1.2%. Impurities or stains attached to the surface of stainless steel sheet plate will seem more difficult to deal with, but in fact, we are wrong. So how to deal with the impurities on the surface of stainless steel sheet plate?

With the rapidly development of the global stainless steel industry, it has been widely used around the world. Some media in the air that are corrosive to stainless steel, such as chlorine, sulfur, etc. After the pickling passivation process, a chromium oxide film will form on the surface of the stainless steel, which can prevent intergranular corrosion of stainless steel by harmful ions. After the pickling passivation process, a chromium oxide film will form on the surface of the stainless steel, which can prevent intergranular corrosion of stainless steel by harmful ions. Due to the surface of stainless steel is covered with a very thin and dense passivation film, it solates the corrosive medium, and is the basic barrier of stainless steel protection. Therefore, the passivation process is indispensable for the corrosion resistance of stainless steel plate sheet.

The duplex steel 2205 is composed of 22% Cr, 2.5% mo and 4.5% Ni-C alloy. To some extent, it has features of austenitic and ferritic stainless steel. And the ideal organization is 50% with each other. We can combine the superior toughness of the austennitic stainless steel, high strength of weldable plain stainless steel and resistance to chloride stress corrosion through control the chemical composition and heat treatment process correctly.

Since the 20th century,stainless steel has been widely popular in various fields of the national economy. Looking around, it is everywhere in life.For example, stainless steel bowls, stainless steel spoons, stainless steel thermos cups, etc. Stainless steel of 304 and 316 are austenitic that we often use, whichhave different models. Thereby, they will inevitably be different in performance, application areas and other aspects. Next, let's take a look at the difference between the two.
