Q:Can Q460C steel plate be used as Q235 steel plate?
Q460 Q235 is not recommended when using their mechanical properties, the gap is too large, the yield strength of Q460 basically is 2 times that of Q235, the elongation is worse than that of Q235, but the problem is not used alone, if used in combination with other components, the effect is not very good, but also not conducive to the overall structure of the force transfer, like cotton in the wire, when the tensile force, most will function in the small deformation component, with low elongation, brittle fracture, which is why when substitute materials are used as close as possible. If you want to weld, it is even more troublesome, Q460 welding performance is poor, the welding process requirements are high, can not be treated as simple as welding Q235, which is also an increase in cost.
Q:How to pass through steel at water stop steel plate?
The steel bar cannot pass through the water stopping steel plate, and this should be taken into consideration when arranging the water stop steel plate.Therefore, the water stop steel plate is usually arranged at the end of the plate or wall, but can not be arranged at the edge of the beam column, otherwise the stirrup is interrupted.
Q:What is the aging property of steel plates?
The aging of steel plate is usually due to the diffusion of carbon atoms and nitrogen atoms in the lattice, forming interstitial atoms, which leads to the solid solution strengthening of the steel plate.
Q:What do you pay attention to?
Considering the quality factor, quality of the primer must have good corrosion resistance, and the old paint film or metal layer has good adhesion, excellent filling force, smooth surface; from the construction perspective, quality should be applied to the body of the primer, vehicle repair and local repair; from the view of time and operation high quality, primer volatilization and shorter drying time and simple mixed paint; considering body material, quality repair primer should be used for the old paint, aluminum, galvanized steel, stainless steel, fiber, plastic products, hard wood, putty and other substrates.
Q:What is the function of an automobile leaf spring?
Spring: the multi length and unequal curvature of the folded plate. After installation ends naturally curved upward. When the impact force of the wheel face came when the steel plate deformation, play a buffer, damping effect
Q:How thick is steel filing cabinet usually made of steel plates?
There are generally 0.5 or 0.6mm cold rolled plate, but you need to store items to determine the weight slightly (because the item is stored for a long time, the plates have a fatigue test), some manufacturers use 0.5mm to strengthen the bearing plate, the bottom can reach about 30KG, with the strengthening of and manufacturers not only the two section bending, bearing instead of added 0.5mm to strengthen the
Q:Q195 galvanized steel plate, is it hot or cold?
Q195 galvanized steel sheet, the substrate may be hot-rolled, or may be cold-rolled.Cold rolled coil is rolled and rolled on the basis of hot rolled coil. Generally it is the process of hot rolling, pickling and cold rolling.
Q:Excuse me, what's the difference between cold rolled steel plate and hot plate in steel plate?
In general, cold rolled steel has better strength, hot rolled steel plate has better ductility. The general thickness of cold rolled is relatively small, can have a larger thickness. Cold rolled steel plate surface quality, appearance and dimensional accuracy than the hot plate, and the thickness of the product right rolling thin to about 0.18mm, so it is popular for. The acceptance of the products, can ask professional personage.
Q:P355NL1 what kind of material is the steel plate?
Use: used in petroleum, chemical industry, power plant, boiler, for the production of reactor, heat exchanger, separator, tank, oil tank, liquefied gas, nuclear reactor pressure vessel, boiler, liquefied petroleum gas bottle, hydropower station high pressure pipes, turbine volute equipment and components.
Q:How much is the rent for a day of Larson steel sheet pile
As a cofferdam, Larson steel sheet pile is not only green and environmental friendly, but also has fast construction speed, low construction cost and good waterproof function.
