Q:Excuse me, the difference between round steel, screw steel, steel, plate material, steel wire, hope professional answer?
The 2 plate and steel hot rolled steel plate, it is hard to know, the difference between rebar and rod easily screwed, clear, thread steel by chemical factory is a very deep rib.
Q:How many tons of pressure can the round steel of 70 inches bear?
This simply refers to the vertical compression. The problem of the bracket is whether the round steel is vertically compressed, whether the stiffness of the structure can be safely supported, whether the supporting foundation can withstand the pressure or not, that is a must be taken into consideration.
Q:What's the difference between Q345 round steel and No. 45 round steel material?
Q345 is plain carbon steel, and Steel No. 45 is of high quality carbon steel. The biggest difference between them is that the content of sulfur and phosphorus is different.
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:Will the three steel is steel? It is a steel bar?
Your question is inaccurateThread steels are grade two, grade three, grade four, and even grade fiveFirst grade steel generally refers to the wire rod, also known as wire rod, is a ribbed steel bar
Q:How about tempering No. 45 round bar?
During quenching and tempering, the whole section of the workpiece is quenched and the microstructure of the workpiece is obtained with fine acicular quenched martensite. By tempering at high temperature, the microstructure with uniform tempered bainite is obtained. It is impossible for a small factory to do metallographic analysis of each furnace. It is generally used only for hardness testing. That is to say, the hardness of the quenched material must be reached by the quenching hardness of the material, and the hardness after tempering shall be checked according to the requirements of the drawing.
Q:Can the same grade steel instead of round bar be ok?
Physical and mechanical properties are different. Because of the different chemical composition and strength of reinforcing steel, they are different in physical and mechanical properties. The cold bending property of steel is good, can make the hook 180, screw steel can only make straight hook 90 degrees; steel weldability is good, with ordinary carbon steel electrode can be used to low alloy electrode; anti fatigue performance and toughness in steel bar is good.
Q:How can stainless steel rounds occur? Is it a quality problem?
By the skin bubbles, surface cracks and so on. Crack and steel surface vertical, about 0.8 ~ 1.5mm, no decarburization on both sides, this is caused by the bubble caused by the subcutaneous bubble. The molten steel contains a large amount of gas. When the liquid steel is solidified, the gas is discharged to form bubbles. The outer layer of the slab near the bubble called the subcutaneous bubbles, honeycomb shaped perpendicular to the surface of the billet, billet after rolling, the bubbles inside most welding. But if the subcutaneous bubbles near the slab surface is too close, while heating because of billet surface oxidation or burning of the bubble exposed, the bubble surface is oxidized, thus it is not possible to make the steel welding, surface cracks.
Q:1, three, two, steel, wire rod, round steel what is the difference?
Steel is commonly known as hot rolled ribbed bar, belonging to the small steel steel, mainly used for steel reinforced concrete structure frame. 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:How to distinguish a round bar from forging? Cold drawing? Hot rolling?
Hot rolled round steel, used in construction and general hardware parts processing is very common. Cold drawn round steel (do not know is not cold dial round bar). But I understand by the cold dial round bar Also mainly used in hardware parts processing and production. Such as hinge shaft core or other surface and diameter requirements of production and processing occasions.
