Q:What is the difference between the heat treatment of cold drawn round steel and the heat treatment of wrought round steel?
Normalizing: heating steel or steel parts to the critical point, AC3 or ACM above the appropriate temperature, after a certain period of time in the air cooling, pearlite structure of the heat treatment process.
Q:20# difference between round bar and A3 round bar, can they be used separately?
The first floor of the answer is lame, 20 is a low carbon steel, low carbon steel is A3, and the two carbon content are equivalent, both mechanical properties are equivalent, but they are not the same, the 20 steel is high quality carbon steel, carbon structural steel is A3, not to see the difference. 20 steel better quality, chemical composition, impurity content control are better, and A3 to casually, so if you only occasionally used, that is no problem, if often use, it is a better consistency of 20 steel
Q:What are the differences between the products made of wrought round steel and hot rolled round steel and tested by mechanical testing after heat treatment?
The longitudinal and transverse properties of the free forging or hammer forgings are relatively small, the banded structure is not obvious, and the plastic inclusions are less deformedIt is not suitable to use rolled material for the workpiece with higher requirement of transverse or tangential performanceSampling position should be the same, usually in accordance with standards or technical requirements, such as vertical performance of a three pull, take at 2/3R
Q:Difference between round bar and other steel bars
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.
Q:How can a round steel weld on a flat steel plate be flat and qualified?
On both sides of the steel and welded steel plate, each side of the weld length of 5 times the diameter of reinforcement, welding seam should be welded into a convex arc that is.
Q:What's the difference between round steel and other steel bars?
Different appearance, round steel appearance garden, no grain without rib, other steel surface has carved or ribbed. This causes the round bar and concrete bonding force is small, and other steel and concrete bonding force
Q:Is there a standard for the grounding of pumping units and the length of the length of the angle steel or round steel?
Usually, the grounding depth is 2 and 5M, and the key is that the grounding resistance value should be below 4 Euro
Q:Grade 1 steel is round steel, grade two steel is ribbed thread steel. Are the weight of the two units the same?
Grade two steel is ribbed steel, but the average diameter is calculated. The chemical composition of grade steel and grade two steel is different, but the density of them is the same. Therefore, the unit weight of grade 1 steel and grade two steel is the same.
Q:What kind of steel bars are used in general civil buildings?
Steel is the HRB335, the diameter of 12 to 22, 25, 28, even 32, and then rough generally appear in the mass concrete construction, not commonly used, generally below 25 is commonly used in masonry structure in rural low level below 16 is most commonly used. Used as beams, columns, main bars and stand bars, etc.
Q:Is there any technique for welding round steel?
The welding position is horizontal fillet welding, to control the size of the weld pool of available elliptic transport method the molten iron is brought up, and then try to consider the position of welding welding (a little more than half of small to)
