Q:4145H round steel is equivalent to the domestic brand?
4145H rounds are used in oil drilling tools and are often replaced by 42CrMo in the industry.
Q:The difference between 304 stainless steel round bar and bright round bar
The difference between the stainless steel round bar and the bright round steel of the same material is that the bright circle is cold rolled (or cold drawn), and the black circle is hot rolledThe processing method is different
Q:What is the difference between gcr12 round bar and Cr12 round bar? Can it be used in general?
The two are different in chemical composition.Cr12 is a widely used cold work die steel. It has high strength, good hardenability and good wear resistance, but its impact toughness is poor. The content of Cr was 11.50 ~ 13. The utility model is mainly used for cold punching dies and punches, cold cutting shears, drill sleeves, gauges, wire drawing dies, coining dies, drawing dies, drawing dies and thread rolling dies, which have the advantages of small impact load, high abrasion resistance, and high abrasion resistance.
Q:Why do I use the M25 round bar for the embedded bolt M24?
The problem is that the reinforcement of this 36 is not ordinary steel. This steel bar is called general round bar, and its diameter is 36.2MM. Its concentricity is very high, it is a kind of reinforcing steel that is specially designed for bolt
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:Why is a steel rope made of many wires rather than a round bar of steel?
It is a strand of steel that bends more easily. In general, but the tensile strength is still a single good, but many shares of a broken, will soon be found, easy to change in time, or a broken, immediately out of the accident.
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?
In theory, how big a round steel will have to replace the large thread steel, and if it is cast, then still better to use thread steel, screw steel tensile resistance than round steel by strong
Q:What is the difference between steel and flat steel, round steel and steel?
In fact, for the processing of raw materials are the same, is used when the roller rolling pressure is not the same, there are many different types of tooth roller shaft, can produce different steel, the steel section is square, round cross section is round
Q:Do you need paint for roof lightning proof steel bars?
The roof lightning protection round steel is the use of metal electrical conductivity and the principle of point discharge, the accumulation of the earth's electricity more rapidly spread to the air, play a role in lightning.
