FH32 steel plate is a high-strength structural steel plate used in ships and marine engineering. It has the following properties:1. High strength: FH32 steel pl
27MnCrB5-2 steel is a high-strength steel with extremely high ductility and impact toughness, and is widely used in the fields of machinery manufacturing and au
1. High strength: 27MnCrB5-2 steel has excellent strength through reasonable alloy ratio and heat treatment process. This makes it ideal for manufacturing parts
1. Name meaning of 27MnCrB5-2 steel
- 27 means the steel has an average carbon content of 0.27%.
- Mn means manganese, and its content is about 1%. The addition
The main factors of affecting non-metallic inclusions in SS490 molten steel are: the process control of smelting process and the quality of original paving mate
Non-metallic inclusions exist in SS490 steel as an independent phase, which destroys the continuity of the steel matrix, increases the inhomogeneity of the SS49
In the SS490 steel welding process, the original austenite grains around the weld grow abnormally by the thermal cycle, leading to poor weld quality. However, i
S420ML steel plate is a material used in structural engineering. Its materials include carbon, silicon, manganese, sulfur, phosphorus, chromium, copper, molybde
Perhaps you know what kind of material S420ML is, but do you know any knowledge about hot rolling and flaw detection of S420ML?Hot rolling of S420ML steel plate
S420ML steel plate is a European standard high-strength structural steel plate, which belongs to rolling and weldable fine-grained structural steel. S420ML stee
The cold rolling of QSTE500TM steel usually adopts longitudinal rolling, and the production process of cold rolling generally includes raw material preparation,
QSTE500TM is a low alloy steel with a series of excellent physical and chemical properties, widely used in the manufacture of automobiles, construction machiner
QSTE500TM steel and BW300TM steel are two different steels with different properties and uses. Here are some differences between them:1. Material grade
QSTE500T
Steel plate cutting generally refers to the process of mixing industrial gas and oxygen to reach the cutting temperature, melting, blowing slag and dividing the
The surface of the A242 Type1 steel plate shall not have cracks, knots, folded air bubble inclusions and delamination, etc., which are harmful to use. If there
When brown spots appear on the surface of A242 Type1 weathering plate, people will exclaim, "This must be a fake, A242 Type1 weathering plate will not rust." In
Pay attention to the following points when welding Q265GNH weathering steel:
1.Select the appropriate welding material and welding process. Q265GNH steel contai
·Good corrosion resistance: Q265GNH steel contains more copper, chromium, nickel and other alloying elements, which can form a dense passivation layer to
The continuous casting process is fully protected, and steel plate mold slag for container steel is added to the crystallizer.Q265GNH steel is prone to breakout
Since Q390 steel is a low-alloy high-strength steel, when welding high-strength steel, generally the material with the same strength as the base metal should be
Q390 steel has excellent comprehensive mechanical properties, excellent weldability, cold and hot workability, and corrosion resistance. In addition, Q390 steel
Submerged arc welding is a kind of high-efficiency welding method, and the most widely used in actual production is twin-wire submerged arc welding. For the Q39
According to the sources, the inclusions in X65 pipeline steel can be divided into two categories: endogenous and exogenous. Among them, the endogenous inclusio
Inclusions in X65 pipeline steel mainly exist in the form of non-metallic compounds, such as oxides, sulfides, nitrides, etc. Non-metallic inclusions have a gre
