Q:Are steel and round steel the same thing?
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:How many grades of steel are round steel?
There are many kinds of steel. They can be divided into three categories: non alloy steel, low alloy steel and alloy steel by chemical composition. Ordinary steels are mostly unalloyed steels. Their quality is divided according to the impurities in the steel, namely ordinary quality carbon steel, high quality carbon steel and special quality carbon steel three kinds. Not by category.
Q:What is the difference between a circle and round steel continuous casting
Round steel drawn from a continuous casting is called a round billet; the rolled round steel is called a bar.
Q:What are square steel, rectangular tube, angle steel or light steel?
Light steel is also a relatively vague term, generally can have two kinds of understanding. One is the current "code for design of steel structures" (GBJ 17-88) in the eleventh chapter "bar, small angle light steel structure", refers to the use of steel and light steel structure is less than L45*4 and L56*36*4 angle steel production, mainly in the lack of time for small steel structure manufacturing of reinforced concrete structure should not be used, has been basically not used, so the revised code for design of steel structures has been basically removed this tendency. The other is the "Regulations" technology of steel structure of light-weight buildings with gabled frames with light roof and wall light (also has the condition to use the masonry wall) single portal frame structure, the light here mainly refers to the enclosure is made of light material. Since the former has been cancelled soon, the meaning of "light steel" mainly refers to the latter
Q:What's the difference between a round tube and a round tube?
Round steel is generally refers to steel, the surface is not threaded, different from round steel pipe, round tube is round tube.
Q:What is the difference between common wire and high-speed wire?
P line: refers to the use of "ordinary mill (usually open-train double wire rod rolling mill)". The rolling speed of 20-60 meters per second, per root weight (disc) in 0.4-0.6 tons (market show is generally three root six head is a market), in the rolling process can only be cooled by air cooling or air cooling line to ensure product performance.
Q:How can I connect channel steel and round steel?
First, the channel steel, channel cut, need to connect the length of the arc shaped gap, and then again and round steel arc surface welding, welding before the two kinds of materials to rust, and full welding.
Q:Are lightning checks required for galvanized steel, flat steel and round steel?
The corrosion resistance of cold galvanizing is not as good as that of hot-dip galvanizing. It is used as lightning protection and grounding material. It is corroded quickly, and the grounding resistance is raised rapidly. It exceeds the required resistance.
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:What is the difference between strip steel and round steel? Where are they mainly used?
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. 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.Mainly used in the manufacture of various tools, cutting tools, moulds and tools (see tool steel), but also a large number of used in the manufacture of various mechanical parts.
