Usage and Applications of Forged GB/AISI/JIS Standard 4130 1.7218 SCM430 25CrMo4 Half Round Steel Bar

1. Steel round bar is used in a large number of architectural and engineering structures. Or it can be used in construction of plants for the production of steel house frames, high-voltage transmission towers, bridges, vehicles, boilers, containers, ships, etc.

2. And we can use this kind of product on the performance of the mechanical parts if the demand is not very high.

3. Some special material steel round bar can be used for main shaft of steamer, hummer shank, with big section and supper force.

Q:Three - grade thread Phi 10 steel can replace a grade Phi 12 round bar? Which elder knows, trouble pointing.
According to the substitution of steel bars, one method, equal strength substitution, equal area substitution and equal root substitution can be obtained by substitution. Three grades of thread Phi 10, steel replaced by a grade Phi 12 of the round steel, I think it may appear: does not meet the minimum reinforcement ratio requirements and reinforcement construction regulations. Don't change it for the best. But must change, must pass the design.
Q:How many grades of steel are round steel?
There are many kinds of steel. They can be divided into three categories: non alloy steel, low alloy steel and alloy steel by chemical composition. Ordinary steels are mostly unalloyed steels. Their quality is divided according to the impurities in the steel, namely ordinary quality carbon steel, high quality carbon steel and special quality carbon steel three kinds. Not by category.
Q:What kind of nuts do you need for round 20 rounds?
The nut is connected to mechanical equipment parts, through the inside of the thread, the same specifications of nuts and bolts to connect together, such as M4-P0.7 and M4-P0.7 only bolt nut series connection (nut, M4 nut diameter is about 4mm, 0.7 fingers between the two thread distance of 0.7mm); US made products as well, such as screw nut only with the 1/4-20 1/4-20's collocation (1/4 refers to the nut inner diameter is about 0.25 inches, 20 inches each, 20 teeth).Self locking nut, lock nut, locking nut, four claw nut, the nut is screwed into the nut, screw rod nut insurance connecting nut cap nut six self-locking angle of anchor bolt with nut, six special angle crown thin nut eyenut.
Q:Embedded bolts M24 why use M25 round steel?
Such as using 24 of the round steel, worried about the surface quality of steel when the processing can not be nominal diameter 24 of the standard thread, of course, the election is too large and wasteful, so generally choose 25 of the round bar,
Q:On the market, 8mm Round Bar is not 9 meters a root? How much does it weigh about 300 meters? How much does it cost?
8 there is no regular reinforced steel bars are straight, round, there is straight, as you said 9 M 1, but that's rolling, if their home, can also, engineering is prohibited
Q:What's the difference between round steel and screw steel? Which is cheaper than steel on the market these days?
Round steel and thread steel are mainly made of different materials and purposes, so prices are different, and they need to be chosen according to actual needs.
Q:Is steel bar round wire? What's the difference? What are the main applications of wire rod?
The difference between steel and other steel: 1 is not the same, round shape light garden, no pattern without ribs, other steel surface appearance is engraved or ribbed. Bond thus causing steel and concrete, and the bond strength of steel and concrete. The other 2 ingredients are not the same, (a steel bar) belongs to the ordinary low carbon steel, alloy steel reinforced many other. 3 strength is not the same. The low strength steel and other steel with high strength, i.e., diameter of the same size as compared with other steel, round steel can bear the pulling force than other reinforced small, but the plastic steel reinforced bar is stronger than the other, larger the deformation in the break before, while the other bars in the break before the deformation is much smaller.
Q:Difference between forging and round steel
The advantages of a casting include an extensible length, a contracted cross section, a contracted length, an extended cross section, a variable length, and a variable cross section. The types of casting are free forging / hand forging, hot die forging / precision forging, top forging, roll forging and die forging.Forgings are not limited to round shapes.Round steel is a solid strip of steel whose cross section is round. The specifications are expressed in millimeters of diameter, such as "50", which means a round bar of 50 millimeters in diameter.Round bar is divided into three parts: hot rolling, forging and cold drawing. Standard Specification for hot rolled round steel is 5.5-250 mm. Of them: 5.5-25 mm small round bars are mostly supplied by straight strips. They are used as reinforcing bars, bolts and various mechanical parts. They are more than 25 millimeters of round steel. They are mainly used in the manufacture of mechanical parts or seamless steel tube billets.
Q:The 8 thread can replace the beam stirrups by steel
Fixed beam and beam is set in the stirrups stirrups, stirrup stirrup is higher than that of the non quota subheadings subheadings, because all trouble making and binding stirrups. In addition, need to see which parts of the ring beam.
Q:Can steel bars be replaced by large screws in the concrete floor?
Tensile strength, extensibility, yield point! The same thread can be used instead!Of course, the number of roots must also be the same ~ only specifications vary!
