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
ST52 is a low carbon manganese steel with good impact resistance and tensile strength. The thickness of plate steel ST52 can vary depending on the application a
ST37-2 steel is a carbon structural steel commonly used in the construction of buildings and structures. Its equivalent grades include ASTM A36, JIS SS400, and
Meaning:
S355J2WP is a corrosion-resistant steel under the EN 10025_5 standard, "S" means structural steel, "355" means the yield strength is 355MPa, "J2" refer
After adding phosphorus, copper, chromium, nickel and other trace elements to the S355J2WP steel, the surface of the steel will form a dense and highly adhesive
Before weathering treatment, we must consider the following three points:
a.The following conditions are not suitable for weathering treatment of S355J2WP: (1)
There are many welding methods for gas cylinders, commonly used are electrode arc welding, submerged arc welding, argon tungsten arc welding, and melt inert-gas
In the manufacturing process, controlling the inclusions and gas content in SG295 steel is the key to welding steel cylinders, and the purity of SG295 molten st
Cooling of SG295 steel adopts two-stage cooling process. The degree of supercooling can be increased through a period of cooling. When SG295 steel is cooled to
In order to improve the strength and formability of HP265 steel and make the products meet the standard requirements, it is essential to design an accurate proc
There are three reasons for the surface wrinkle of HP265 steel plate:1.There are obvious banded structures in HP265 steel. Due to uneven cooling, the cooling ra
Controlled rolling is an important means to improve the strength and toughness of HP265 steel. It is widely used in industrial production because it has the fol
Both A283 Gr C and ASTM A285 grade C carbon steel are low to intermediate tensile strength carbon steel plates used primarily in the fabrication of storage tank
To ensure the quality of plate A285 grade C, various inspections and tests can be conducted during the manufacturing process. These inspections and tests includ
A285 Gr.C plate is a low to intermediate tensile strength carbon steel plate used primarily in the fabrication of storage tanks and other similar applications.
Cutting
Generally, the common cutting methods include plasma cutting and laser cutting, which can achieve high-precision cutting and seam cutting of NM400 steel
It is inevitable that there will be different problems in the production process of the steel plate. What defects may appear on 16Mo3 steel plate?(1) Layered. L
16Mo3 is named according to the content of C (carbon) and Mo (molybdenum), which means that the carbon content of this steel plate is about 0.16%, and the conte
A537 steel plate is heat-treated carbon-magnesium-silicon container plate, which implements ASTM standards. There are three grades of A537 steel plate, namely A
To identify the quality of ABS grade AH36 steel, there are several factors to consider. Firstly, check that the material meets the chemical composition and mech
