12Cr1MoV steel has good welding performance and is sensitive to the cooling rate of normalizing. When the cooling is faster, the durable strength is higher. 12C
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
12Cr1MoV is an alloy structural steel, which implements the GB/T3077-1999 standard, and the unified number code is A31132. The 12Cr1MoV grade is expressed in se
12Cr1MoV is a commonly used heat-treated modified superalloy material with good heat resistance, corrosion resistance and tensile properties. 12Cr1MoV steel is
The creep limit of 12Cr1MoV steel is similar to the value of enduring strength. It has high plasticity when it is stretched for a long time, and the thermal str
Silicon element (Si) is an important agent of reducing and deoxidizer in the process of smelting 51CrV4 steel: for many materials in carbon steel, it contains l
In order to reduce the cracking phenomenon at the end of 51CrV4 steel, it is recommended to take the following measures:
1.Control the cooling of 51CrV4 steel a
The main reason for cracking at the end of 51CrV4 spring flat steel is: due to improper cooling after rolling, bainite structure appears in 51CrV4 steel structu
51CrV4 is a more advanced spring steel, which is used as a high-load important spring with a large cross-section and a valve spring, piston spring, and safety v
51CrV4 is a high-strength steel suitable for quenched and tempered springs, which combines the characteristics of springs with excellent wear resistance and imp
At present, the commonly used steel types for diamond welding saw blade substrates are 75Cr1, 60Mn, 51CrV4, 50Mn2V and 30CrMo.60Mn is the most common low-end st
Hot cracks are generated at high welding temperatures. When crystallized, the eutectic with low melting point forms a liquid film, which will lead to cracking u
The influence of Cu and P elements on 05CuPCrNi steel is explained in the previous article,this article briefly describes the effects of Cr and Ni Elements on 0
09CuPCrNi-A steel plate is a kind of weathering steel (atmospheric corrosion resistant steel), which is used in sulfur-containing flue gas, air preheater, econo
There is no standard size for steel plate SM570 as it can be produced in a range of sizes depending on the requirements of the project. However, SM570 steel pla
SM520C steel is a low-alloy, high-strength structural steel commonly used in the construction of bridges, buildings, and other infrastructure projects. The chem
The SPA-C steel billet is hot delivered and hot loaded to a 1500mm hot continuous rolling mill for rolling. SPA-C steel has a high Cu content, and "copper embri
·Good corrosion resistance: SPA-C steel contains more copper, chromium, nickel and other alloying elements, which can form a dense passivation layer to p
The continuous casting process is fully protected, and steel plate mold slag for container steel is added to the crystallizer. SPA-C steel is prone to breakout
Pay attention to the following points when welding SPA-H weathering steel:
1.Select the appropriate welding material and welding process. SPA-H steel contains c
Smelting Process
The molten iron required for smelting SPA-H steel must undergo desulfurization pretreatment. Before entering the converter, the sulfur content
SPA-H weathering steel is a low-alloy structural steel. Its chemical composition contains not only a certain amount of carbon (C), but also other elements such
Due to the factors of different regions, environments and climate, the time for forming a stable oxide film on the surface of 05CuPCrNi also varies greatly. In
The main purpose of adding C, and P to 05CuPCrNi is to improve the corrosion resistance and solid solution strengthen ferrite.Cu is the most important and most
05CuPCrNi steel is a high-strength weather-resistant steel plate (atmospheric corrosion-resistant steel), which has the characteristics of high-quality steel su
