Q:Is round bar steel?
For example, the steel structure material is Q235B, and the steel bar is HPB235. Although the strength is the same, the production process is still different, the requirements of higher steel bar, there is a new specification more stringent.
Q:Why is round steel more expensive than thread steel?
Thread steel is generally used for building convenience. Round steel is widely used in industrial manufacturing and processing. And, as mentioned above, there are many kinds of round steel materials, and there is not much comparability between the prices.
Q:What's the difference between pure iron round steel and electromagnetic pure iron bar?
One thing, one thing, the same thing is round. However, in the general industry, about 30 of the habit is called bar,
Q:Is yuan steel round steel?
The difference between steel and other steel: 1 is not the same, round shape light round, no pattern without ribs, other steel surface appearance is engraved or ribbed, cohesive force that cause steel and concrete, and the bond strength of steel and concrete in the other. 2 ingredients are different, round steel (grade a steel) belongs to ordinary low carbon steel, and other steel bars are mostly alloy steel.
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:What are the differences between hot rolled stainless steel rounds and cold drawn round ones?
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. Where: 5.5-25 mm small round steel mostly straight bundles of supply, used for steel, bolts and various mechanical parts; greater than 25 mm round steel, seamless steel pipe is mainly used for the manufacture of mechanical parts of the tube, etc..
Q:12 of the diameter of the round steel can be M12 out of the thread is not
No problem。 M12 coarse thread of the pitch is 1.75, the outer circle to be processed to 11.8mm, the thread of the most beautiful shape. If the outer circle is too large, the tip of the tooth is too small and very easy to deform.
Q:How many meters is the minimum loading surface of galvanized steel wire for grounding grid?
Round steel (grade 1 steel) belongs to ordinary low carbon steel with low strength. However, the plasticity of the round bar is stronger, that is, the round steel has a larger deformation before it is pulled off.It has been widely used in the fields of hardware, construction, automobile, shipbuilding, petrochemical, machinery, medicine, food, electricity, energy, space, etc.. The most extensive machining of general machine parts, general rod type steel parts, CD pole, bolt, nut.
Q:The difference between round face and round bar steel on concrete?
The difference between round bar and round bar is that the surface has longitudinal ribs and transverse ribs, usually with two longitudinal ribs and transverse ribs uniformly distributed along the length direction. The rebar is a kind of small section steel, mainly used for the skeleton of reinforced concrete construction members. In use, some mechanical strength, bending deformation property and welding performance are required. The raw steel billet for the production of threaded steel is carbon structural steel or low alloy structural steel which is treated by calm melting, and the finished steel bar is delivered in hot rolling forming, normalizing or hot rolling state.
Q:What is galvanized round bar?
A cylindrical bar of iron or steel bar that crosses a layer of zinc on its surface.
