- It is annealed before ex-factory, which ensure good metallographic structure, proper hardness and good workability. There is no need to anneal again.

- But It must be re-annealed if reforged, as the original organization and performance are destroyed after reforged, and the forging stress increased.

- Normally it will be annealed twice and the temperature of the second annealed is 20°C lower than the first one.

Q:Specifications of the same kind of galvanized round bar more expensive than round steel?
The general market price than ordinary steel galvanized steel bar of your 2000-3000 dollars per ton, according to your purchase requirements, price range of relatively large fluctuations, such as whether to open a formal invoice, transport distance, purchase quantity, relationship with your level of economic development, the developed area of fierce market competition, the price is relatively low. The prices and prices of large factories and small factories are not the same. The prices of big factories are generally high, and the prices of small factories are low.
Q:Difference between forging and round steel
The castings need to be uniform in each piece without any porosity, excess space, inclusions, or other defects. The component produced by this method has a high ratio of strength to weight. These elements are usually used in aircraft structures.
Q:The difference between 304 stainless steel round bar and bright round bar
Stainless steel rounds are not required on the surface. They may come with black leather. They may be pickling surfaces or cold drawn or polished surfaces;Stainless steel bright round steel refers to polished surface or cold drawn surface round steel.304 is the brand, and the surface quality has nothing to do with.
Q:Is round steel round steel?
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. Of which: 5.5-25 mm small round bars are mostly supplied by straight strips. They are used as reinforcing bars, bolts and various mechanical parts. Round bars larger than 25 millimeters are used mainly for making mechanical parts or for seamless steel tubes.
Q:Are the bolts for the round bar or round steel?
The template is generally used round bar, two ends of the wire, wear the backing plate after the nut.
Q:12 of the diameter of the round steel can be M12 out of the thread is not
It depends on your material straight straight, generally should be right, you check the metric thread specification table, there is large size can be much, I think you are a little round a little better, so that you may get the car, do not appear to have a side material shortage phenomenon
Q:Which is hard, round steel or screw steel?
If the diameter is the same, of course, the rebar is of great hardness.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:What is the difference between common wire and high-speed wire?
The universal wire and high speed wire are the wire rods (bars) of the rolling mechanism.High wire: refers to the use of high-speed torsion mill rolling wire rod. The rolling speed of 80-160 M / s, each weight (disc) in 1.8-2.5 tons, tolerance of high precision (up to 0.02mm), in the rolling process by adjusting the process parameters (especially in the cooling line) to ensure the different requirements for the product.
Q:How can stainless steel rounds occur? Is it a quality problem?
Cracks caused by inclusions in steel, cracks and steel surface of a certain angle, about 1 ~ 2.5mm, slightly decarburization on both sides, decarburization layer 0.10 ~ 0.15mm. There are inclusions on both sides of the crack and in the tail, and the ferrite band is formed
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.
