Q:20 round bars are of several grades
No. 20 cold drawn steel belongs to high quality low carbon steel, cold extrusion, carburizing hardened steel. The steel has low strength, toughness, plasticity and weldability. The tensile strength is 355-500MPa, elongation is greater than or equal to 24%.
Q:Why is round steel more expensive than thread steel?
Round steel has a wide range of applications, many brands and different uses. Such as machining, shipbuilding and other user processing requirements are also different. Such as alloy round steel, Q345B, high carbon steel, 45#, 35#, general round Q235B, mainly material, ingredients, etc..
Q:How many meters is the minimum loading surface of galvanized steel wire for grounding grid?
Galvanized round bar and galvanized flat steel are of different shapes and different uses.Galvanized round steel refers to the cross section of round solid steel. The specifications are expressed in millimeters of diameter, such as 50, which means a round bar of 50 millimeters in diameter. Round steel is not the same as other steel bars. Round steel is round in shape and has no ribs and no ribs, which makes the bonding strength between round bar and concrete very small.
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 are the differences between the products made of wrought round steel and hot rolled round steel and tested by mechanical testing after heat treatment?
The longitudinal and transverse properties of the free forging or hammer forgings are relatively small, the banded structure is not obvious, and the plastic inclusions are less deformedIt is not suitable to use rolled material for the workpiece with higher requirement of transverse or tangential performanceSampling position should be the same, usually in accordance with standards or technical requirements, such as vertical performance of a three pull, take at 2/3R
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.
Q:45# what are the main rounds for?
45# round steel refers to the cross section of round solid steel. The specifications are expressed in millimeters of diameter, such as "50", which means a round bar of 50 millimeters in diameter
Q:How can a round steel weld on a flat steel plate be flat and qualified?
It is required that the current is suitable and the bar is stable. If required, the groove can be turned on the round steel to ensure that the welding is beautiful and qualified
Q:What kind of steel is used for anchor bolt material? What's the quality of anchor bolt material?
The anchor bolt can be divided into fixed anchor bolt, movable anchor bolt, expansion anchor, anchor bolt and bond anchor bolt. According to the different shapes, they are divided into: L type embedded bolt, 9 type embedded bolt, U type embedded bolt, welding pre embedded bolt, bottom plate embedded bolt
Q:How to determine the welding seam height of steel plate and steel bar?
If the end of the vertical plane and the steel plate welding, welding angle as the bar diameter and the general welding height is 0.7 times the diameter of the arc can be reinforced; if the length direction of the surface of steel plate and steel welding, 2 side fillet weld cracks in the welded steel plate and steel between the full and round steel weldment the maximum diameter of arc phase can be flat.
