- 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:What kind of nuts do you need for round 20 rounds?
Common materials for 301, 304, 303, 316, 316L, 304L, 321, 2520, 201, 202 and so on. Specifications are expressed in diameter, such as "50", which means a round bar of 50 millimeters in diameter. 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.Stainless steel round bar has a broad application prospect, and is widely used in hardware, kitchenware, shipbuilding, petrochemical, machinery, medicine, food, electricity, energy, aerospace and other architectural decoration. Equipment, chemicals, dyes, paper making, oxalic acid, fertilizer, etc.; equipment for photography, food industry, coastal areas, ropes, CD poles, bolts, nuts, etc..
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:Is the shear wall concealed column stirrup steel or round steel?
Specify the construction drawing is HPB300 is hot rolled round bar, that is HRB335, HRB400 is the hot rolled ribbed bar. Don't call thread steel, this name has long been abandoned. Simple, light marked wall column reinforcement detail construction drawing on the diameter and spacing is not encrypted, what non encrypted area, like the dense spacing.
Q:Embedded bolts M24 why use M25 round steel?
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 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:What's the difference between bearing steel and round steel?
Steel: steel widely used, a wide range of products, according to the shape of the cross section, the steel is generally divided into profiles, plates, pipes and metal products in four categories. Steel is a material of shape, size, and performance made by pressure processing of ingots, billets, or steel. Most steel processing is through the pressure processing, so that the processed steel (billets, ingots, etc.) plastic deformation. According to the steel processing temperature, can be divided into cold processing and hot processing two.
Q:The problem of dowel bars on concrete pavements?
Light bar shall be adopted for dowel barWith transverse expansion joint as an example: in the face of layer thickness is 220mm, dowel diameter is 28mm (28), the minimum length of the dowel bar is 400mm, the maximum dowel bar spacing is 300mm.
Q:Is round 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. 3 strength, steel and other steel with high strength low strength, namely, diameter of the same size as compared with other steel, round steel can bear the pulling force than other reinforced small, but the plastic steel reinforced bar is stronger than the other, there is a large deformation in the break before, and it reinforced the deformation the break before the much smaller
Q:What kind of steel bars are used in general civil buildings?
In the general construction of commonly used hot rolled round bar (commonly known as round steel), hot rolled ribbed steel bars (commonly known as steel), the two most widely used steel. Identified as HPB235, the diameter of 6.5, 8, 10, 12, and then rough is not commonly used, and in the 6.5 and 8 most as commonly used, used as column, main reinforcement and stirrups and plate reinforced beam distribution.
Q:Can the same grade steel instead of round bar be ok?
The above analysis, threaded steel than round steel performance is good, in general circumstances can be replaced.
