Low-alloy high-strength steel grades are designed to have quite good notch toughness for their intended structural use. The applicability of the notch toughness of specific grades of low-alloy high-strength steel is either based on existing use experience
Low-alloy structural steel plates are mainly used in machinery manufacturing and metal structural parts. Advantages of A572 Gr 55 CS steel carbon plate, low-alloy structural steel plates: They have superior performance and light weight. Disadvantages of
The diameter of large diameter seamless steel pipe is 325mm-1220mm, and the maximum thickness that can be achieved is 200 mm. The diameter of small diameter seamless steel pipe is generally less than 89mm. The processing technology of large diameter seaml
During the construction of hot-dip A572 Gr 65 high strength steel galvanized pipe, the correct welding process shall be adopted, the inspection and acceptance shall be carried out in strict accordance with the specification, and the anti-corrosion treatme
How to distinguish the inferior steel plate? 1. The surface of the fake and inferior steel plate is easy to produce scab. 2. The material of fake and inferior steel plate is not uniform and there are many impurities. The surface of fake and inferior steel
The main uses of flat steel are as follows. First, flat steel is used as a raw material for processing steel plates, which is convenient for transportation, takes up a small space, and can save transportation costs. Second, A514 Gr T alloy steel plate fla
TMCP process is an important means to improve the comprehensive properties of steel. It can be used to produce ship plate, vessel plate, boiler plate, bridge steel, etc. Compared with the normalized steel of the same strength grade, TMCP can reduce the al
The outer diameter of the hot-rolled seamless pipe is generally larger than 32mm, and the wall thickness is 2.5-75mm. The diameter of the cold-rolled seamless pipe can be 6mm, the wall thickness can be 0.25mm, the outer diameter of the thin-walled pipe ca
For A588 grade A heavy plate buyers, the impact of the rise and fall of A588 grade A heavy plate prices is great. Because of the large amount of A588 grade A heavy plate purchases and the large amount of funds involved, many A588 grade A heavy plate purch
What is the specific use of A588 Gr B structural steel plate, hot rolled plate in daily life? First of all, hot rolled plate is used in bridge, vehicle structure, frame and other fields to play a role of bearing pressure. Secondly, high pressure boiler ve
Mg element can reduce the number, size, distribution and morphology of inclusions in steel such as ASTM A514 alloy steel plate. Micro Mg can improve the size and distribution of carbides in bearing steel. And the carbide particles of bearing steel contain
Rolling steel is the process of pressing to change the shape of the ingot and billet between the rotating rolls. The so-called steel rolling process is a combination of a series of steel rolling processes. The entire rolling production process is always c
Our company produces ordinary carbon steel A709 grade 50 structural steel sheet with high strength and good plasticity and toughness. Due to the effect of alloy elements, its strength is 25% - 50% higher than that of ordinary carbon steel, its elongation
Rolled sheet is a very common material in industrial construction. Rolled sheet at room temperature is cold-rolled sheet, and cold-rolled sheet is the rolling of hot-rolled coils below the recrystallization temperature. The hot-rolled sheet is rolled abov
As for the mechanical properties of A709 grade 50 carbon steel plate, ASTM A572 Gr.50, 345 Mpa is the yield point levels most closely approximating a geometric progression pattern between 36 ksi min yield point steels covered by Specification A36/A36M and
The effect of alloy elements on the properties of heat treatment methods for thick steel plate: the performance of heat treatment method reflects the difficulty coefficient level of heat treatment process and the tendency of defects caused by heat treatme
In recent years, in line with the development trend of iron and A709 Gr HPS100W bridge steel plate steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product ser
SM490B is a structural steel produced according to Japanese standard JIS G3106, with a strength σb of 490MPa. This standard applies to bridges, ships, vehicles, petroleum storage tanks, manufacturing plants, general construction and various engi
DIN 17102 TStE285 steel plate/sheet, DIN 17102 TStE285 steel plate/sheet, under DIN standard we can regard TStE285 steel plate/sheet as fine-grain structural steels, normalised rolled steels. A573 grade 70 structural steel plate, DIN 17102 TStE285 is main
The purpose of A283 grade B CS steel carbon plate quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve th
The blanking of the structural steel plate is first to find 90 degrees, and then use a tape measure and a powder line to draw the cutting range. According to the thickness of the carbon steel plate plus the cutting allowance, drilling is required. For the
