Q:Can I use steel bar instead of steel bar?
But there is a difference between steel reinforcement ratio can good toughness steel reinforced high strength reinforced surface than the thread in the engineering application of the surface force can he assisted according to what you want instead of general effect is no problem except in mechanical parts to replace.
Q:What is the difference between the heat treatment of cold drawn round steel and the heat treatment of wrought round steel?
Solution heat treatment: the alloy is heated to a single phase at high temperature to maintain constant temperature, so that the excess phase is fully dissolved in the solid solution, and then cooled rapidly to obtain the heat treatment process of supersaturated solid solution.
Q:How many roots are there in a standard ton of steel and how many meters are there in a steel bar?
Generally, the length of steel bars is 6 meters, 9 meters, 12 meters, 6 meters, which is rarely seen on the construction site. A standard bundle is 2 tons.
Q:Embedded bolts M24 why use M25 round steel?
Because M25 round steel machine processing, the direct use of M24 round steel accuracy is not guaranteed
Q:Why is round steel more expensive than thread steel?
Thread steel is generally used for building convenience. Round steel is widely used in industrial manufacturing and processing. And, as mentioned above, there are many kinds of round steel materials, and there is not much comparability between the prices.
Q:Round bars and ribbed stirrups are much better
The flexibility of hot rolled round steel bar is better than that of ribbed steel bar, and its fatigue stress amplitude is wide allowable. It is suitable for the components under dynamic load, as well as lifting rings, rings and lifting workpieces;
Q:Grade 1 steel is round steel, grade two steel is ribbed thread steel. Are the weight of the two units the same?
Grade two steel is ribbed steel, but the average diameter is calculated. The chemical composition of grade steel and grade two steel is different, but the density of them is the same. Therefore, the unit weight of grade 1 steel and grade two steel is the same.
Q:Is there a standard for the grounding of pumping units and the length of the length of the angle steel or round steel?
Usually, the grounding depth is 2 and 5M, and the key is that the grounding resistance value should be below 4 Euro
Q:Is there a steel bar of 6 diameter on the market?
There is no rebar of 6 diameter on the market.
Q:How many meters is the minimum loading surface of galvanized steel wire for grounding grid?
Flat steel adopts negative deviation rolling, but according to actual weight delivery, the utilization ratio of steel plate increased by -5 percentage points. Flat can according to user needs, set the thickness, width and length of production, for the user to reduce the cut and save processes, reducing labor, material consumption, but also reduce the loss of raw materials processing, time saving, material saving. Products have been specialized in steel structure manufacturing, machinery manufacturing, automotive industry, mining machinery, lifting machinery and other industrial materials.
