Q:What is the hardness of the wear-resistant steel plate?
The main application of impact resistant steel plate:All kinds of medium and heavy stamping, drawing, forming, printing, forging mold.The motor of /EI silicon steel sheet stamping die drawing, canned, impact punch, cold forming.Thick cold tie plate drawing die, stainless steel precision punch, cold extrusion, reverse extrusion convex die.
Q:Steel plate for steel structure, what kind of steel plate is it?
The grades of carbon structural steel are composed of four parts: the yield strength, the letter Q, the yield strength value, the quality grade mark (ABCD), and the deoxidation method notation (FZTZ).
Q:What material can be replaced by 345D steel plate?
The steel plate is divided into hot-rolled and cold-rolled parts according to rolling.
Q:What do you pay attention to?
In the rapid development of the automotive industry, in order to reduce the weight of the car itself, a variety of lightweight base material is more used by the car, such as plastic products, glass steel and so on. Due to the organizational structure of various materials with different degree of hardness, such as paint layer compared with the plastic to some hard, so it is the same as sandpaper polished plastic will be wiped out some results in the emergence of many, uneven phenomenon, due to very shallow depression layer is in a flat surface, so the putty adhesion is poor. And dry time is slow, difficult grinding. In this case, only the two fill method is used to solve the problem.
Q:Who knows the wire width of the steel mesh?
Steel wire should be called stem stem.
Q:How can steel plates with a thickness of 1MM be welded?
Spot welding is the welding joints in the contact surface of the individual points are welded together. The metal spot welding have better ductility. When welding, the welding surface is clean, then by sheet lap welding assembly, pressure between two cylindrical copper electrode, pressing force applied by means of the current. Large enough, resulting in a large number of heat resistance at the contact plate, the center of the hottest areas of the metals quickly heated to high plasticity or melting state, the molten pool formed a lens shaped. To keep the pressure off the current, the metal cools, forming a solder joint.
Q:What's the density of the 0.5 color steel plate?
We often see the color steel plate refers to the processing of sheet metal, the thickness of about 50~100mm, it is composed of the middle filler and two sides of color steel plate. Among them, the color plate thickness of 0.4mm, 0.5mm, 0.6mm and other different thickness, the middle layer can be polyurethane, rock wool or foam plastic. Because of the special profiles, the construction of the building with colored steel plate is very fast (such as the Xiaotangshan hospital in SARS), but the strength is low. The substrate of the color coated steel plate is a cold rolled substrate, a hot-dip galvanized substrate and an electro galvanized substrate. The coating types can be divided into polyester, silicon modified polyester, vinylidene fluoride and two plastic sol. The surface state of color coated steel sheet can be divided into coated plate, embossed plate and printed board.
Q:What is muotileaved spring? What is the little leaf spring?
Leaf: ranging from multiple pieces of the same length, width of sheet steel by adding together. Multi leaf spring of each leaf into superposition inverted triangle shape, the top plate is the longest, the bottom plate is the shortest, piece number and supporting the weight of the bus plate, plate more thick more shorter, more rigid spring. However, when the leaf springs are used for a long time, they slide and rub each other. The relative friction between the steel plates also causes spring deformation, resulting in uneven running.
Q:What's the difference between steel plate 20 and Q235 steel plate?
In the normalizing state of No. 20 steel, the yield point is 245MPa, the elongation is >25%, the quenched and tempered state, the yield point is 280MPa, and the elongation is >22%. Widely used in the production of small, high load toughness requirements of parts, such as rod, heavy and general machinery in forging the sleeve, fixture and liner, general machinery and automobiles and tractors in small parts of carburizing, cyaniding.
Q:What does "Z" mean to the performance of steel?
To apply for Z steel plate thickness and subjected to tensile load on just the thickness direction has the performance requirements, it is in a certain level of structural steel (called parent steel) on the basis of the special treatment (such as calcium treatment, vacuum degassing, argon stirring etc.) and proper heat treatment steel.
