What is the material? Where is the best quality bonded steel? Shanghai Lijia is the first choice for bonded steel. Shanghai Lijia is an expert in the distribution of bonded steel. Its varieties include various forms of bars and plates. Next, let’s take a look at Shanghai Lijia’s introduction to bonded steel:
Round bar sales: diameter, average In stock
Round bar classification: machined round, polished round, black fur round
Plate sales: thickness, all in stock
Plate classification: machine-rolled plate, forged plate, forged plate, Tie plate
Product notes: retail, wholesale sold at wholesale price starting from tons
Below, the classification components and properties of alloy steel are introduced:
The role of alloy elements in structural steel: affecting the recovery of steel fire process. Since alloy elements can hinder the diffusion of various atoms in steel during tempering, compared with carbon steel at the same temperature, they generally play the role of delaying the decomposition of martensite and the aggregation and growth of carbides, thus improving the The tempering stability of steel, that is, improving the tempering softening resistance of steel, has a more significant effect, while the effect of ",", "r" and "r" is not obvious. Steel containing a higher content of carbide-forming elements such as carbide, carbide, etc., when tempered at ~°C, fine and dispersed special carbide material points such as carbide, carbide, etc. will precipitate to replace part of the larger alloy cementite, thereby increasing the strength of the steel. It no longer decreases but increases, that is, secondary hardening occurs (see tempering). It can prevent or weaken the temper brittleness of steel.

Below is an introduction to the classification and performance of structural steel. For other information, please consult [ 】
.Steel plate is a flat steel material that is poured by molten steel and pressed after cooling. It can be directly rolled or cut from wide steel strip.
.Classification of steel plates (including strip steel):
Classification by thickness: () Thin plate: Thin steel plate mm (thinnest.mm)
() Medium plate
() Thickness Plate: Thick steel plate ~ mm
() Extra thick plate: Extra thick steel plate ~ mm.
Classified by production method: () Hot-rolled steel plate
() Cold-rolled steel plate
The width of the thin plate is ~mm and the thickness is ~mm.
Steel strip, also known as steel strip, has a width within 10%, and the length is slightly different according to the size of each roll
According to thickness, it is divided into thin steel strip (thickness is not greater than) and thick steel strip (thickness is greater than)< br/> According to width, it is divided into wide steel strip (width is greater than) and narrow steel strip (width is not greater than)
. Little knowledge about steel number
⑴
is the abbreviation of steel,
Abbreviation for, (b) represents pipe, () represents tool
Abbreviation for hot, abbreviation for cold
Abbreviation for business
When the tensile test needs to be ensured, add < at the end of the grade br/> When it is necessary to ensure non-timeliness, add
at the end of the grade ⑵ Quenching and tempering code of cold-rolled carbon steel sheets and steel strips:
The annealed state is, the standard quenching and tempering is, the hardness is, the hardness is , hard is, hard is
⑶Surface processing code:
Matt finish rolling is, bright finish rolling is B
