Q:What is the difference between the heat treatment of cold drawn round steel and the heat treatment of wrought round steel?
Solution treatment: the alloy can be dissolved in various phases, strengthening solid solution, improving toughness and corrosion resistance, eliminating stress and softening, so as to continue processing and forming.
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:12mm Round steel, the material is Q235, the maximum weight can bear?
Standard Specification for hot rolled round steel is 5.5-250 mm. Among 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:How to determine the welding seam height of steel plate and steel bar?
If the arc surface in the length direction of the steel bar is lapped welded with the steel plate surface, the gap between the steel plate and the round bar is welded by the 2 side welding angle, so that the welded meat is equal to the largest diameter of the round steel arc surface.
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's the difference between a round tube and a round tube?
Round steel is a medium solid steel, of course the tube is hollow
Q:Are the bolts for the round bar or round steel?
The utility model relates to a pair of bolts which are used for drawing between the inner and the outer formwork of the wall when the beam and the column template are set. The bolt under concrete lateral pressure and other loads, ensure the spacing inside and outside the template can meet the design requirements, but also the template and its support structure fulcrum, so the impact on the overall arrangement of bolt, the template structure stiffness and strength greatly.
Q:What are the differences between hot rolled stainless steel rounds and cold drawn round ones?
The main differences are in mechanical properties. Forged round steel is used in the processing of some special performance requirements. Round steel three processing methods are more common, should be very wide surface.
Q:Can the same grade steel instead of round bar be ok?
Tolerable。1. grades of steel are different (chemical composition is different). Round steel (HPB235) is carbon steel, steel is Q235; thread steel is low alloy steel; HRB335 grade steel is 20MnSi (20 manganese silicon); HRB400 grade steel bars are 20MnSiV or 20MnSiNb or 20MnTi etc.;
Q:Lightning protection earthing zinc plating flat iron and round steel welding method, need to flat iron wrapped in round steel outside welding?
Don't need, but the welding seam area not less than round or flat between the relatively small cross section, the weld to coated with anticorrosive paint. Generally speaking, the grounding part does not use steel, galvanized L type flat iron good effect (copper strip and galvanized L type flat iron is not much, just life is long, but the cost is much higher), round only used as grid wiring.
