Q:What's the difference between bar and round bar?
Quenching is a heat treatment behavior, as raw material will not be quenched, and generally should be normalized or annealed by reasonRound steel can also be used for seamless steel tube perforation, bar material can not be
Q:What's the difference between Q345 round steel and No. 45 round steel material?
Q345 round steel is different from round steel No. 45:Q345 round steel containing Mn, but containing C below 45# round bar45# round steel containing C is higher than Q345 round steel, but without Mn
Q:Is there a standard for the grounding of pumping units and the length of the length of the angle steel or round steel?
What to play a few piles, with triangle connection, these seem to have some places have standards, but a place, a kind of, in general, general one is: ground wire pile to hit the moist soil layer, ensure the grounding reliable
Q:Is round bar steel?
For example, the steel structure material is Q235B, and the steel bar is HPB235. Although the strength is the same, the production process is still different, the requirements of higher steel bar, there is a new specification more stringent.
Q:Difference between cold drawn round steel and round steel
There are different reasons for the residual stress in hot rolled and cold-rolled steel sections, so the distribution of the residual stresses is also quite different. The residual cold-formed steel section stress distribution is curved, and hot rolled steel or steel welding section on the residual stress distribution is thin.
Q:40CrMo what is the round steel material?
Requirements for the manufacture of 35CrMo steel with higher strength and conditioning section large forgings, such as locomotive traction gears, with supercharger drive gear, the rear axle, the connecting rod and the spring load greatly clip, 2000m can also be used for the following deep oil drill pipe joints and fishing tools etc..
Q:How to determine the welding seam height of steel plate and steel bar?
If the arc surface in the length direction of the steel bar is lapped welded with the steel plate surface, the gap between the steel plate and the round bar is welded by the 2 side welding angle, so that the welded meat is equal to the largest diameter of the round steel arc surface.
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:What is round steel?
Round steel is a solid strip of steel whose cross section is round. Its specifications are expressed as millimeters in diameter. For example, "50" means a round steel with a diameter of 50 millimetersRound bar is divided into three kinds of hot rolling, forging and cold drawing. The specification of hot rolled round bar is 5.5-250 millimeters. Among them, 5.5-25 rounds of small round bars are mostly supplied by straight strips. They are commonly used as reinforcing bars, bolts and various mechanical parts;
Q:How many grades of steel are round steel?
Secondly, the round steel only shows the shape of steel, all kinds of steel have round steel, it can not explain the nature and composition of steel.
