Q:What is the aging property of steel plates?
Timeliness refers to the change in performance with time.
Q:How much is 2 millimeters per square meter?
The performance of carbon steel mainly has the following deficiencies:(1) hardenability is low. Under normal circumstances, the maximum quenching diameter of carbon steel water quenching is only 10mm-20mm.(2) strength and yield strength are relatively low, such as the s of ordinary carbon steel Q235 is 235MPa, while that of low alloy structural steel 16Mn is 360MPa and above s. The sigma S / sigma B of steel 40 is only 0.43, much lower than that of alloy steel.(3) the stability of tempering tempering stability, carbon steel in quenching and tempering treatment, in order to ensure the high strength with the tempering temperature is lower, so the toughness of the steel is lower; in order to ensure good toughness, with high tempering temperature strength is low, the mechanical properties of carbon steel level is not high.(4) stainless steel can not meet the requirements of special performance. Carbon steel is often poor in oxidation resistance, corrosion resistance, heat resistance, low temperature resistance, wear resistance and special electromagnetic properties, and can not meet the needs of special performance.
Q:What is a cold rolled sheet with plastic sprayed?
After the cold rolled steel sheet is finished, the surface treatment needs to be carried out, including:1: electroplating: zinc plated, nickel plated, copper plated, gold plated, chrome plated,2: immersion plating: black, hot galvanizing3: spray: spray paint, spray, baking paint,4: polishing, point solution polishing, shot peening, shot blasting
Q:What's the difference between single rolling steel sheet and continuous rolling steel plate?
Single rolled steel plate usually refers to medium plate, in the process of rolling and finishing, the plate has been flat, usually thicker (6mm or more), the width of the fastest up to 4800mm.
Q:What is the thickness of the paint board?
Paint boards are generally used in cabinets or doors and other places, we have often seen, but also understand some of the paint plate thickness of how much better? Paint board is a kind of woodworking materials. It is based on density board as base material, the surface after six to nine times (not the same as the number of Polish manufacturers are different, the more the number of process requirements is high, the cost is higher), the primer, drying, polishing (at the end of three, two, light) high temperature baked. At present, mainly used in cabinets, doors and so on. Paint board can be divided into light, Matt and metal paint three. At present, there are the latest engraving baking paint board, Newcastle house paint baking board and so on.
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 is a die steel plate?
Pressure plate template is made of galvanized steel sheet or the antiseptic treatment, the machine rolled into a groove plate with a cross section of the ladder waveform or project template material open box steel shell.
Q:What is the hardness of the wear-resistant steel plate?
But not the higher the hardness, the better the wear resistance! The hardness is based wear resistant steel plate excellent wear resistance, but the relationship between the hardness and wear resistance is not proportional to the wear resistance; wear resistant steel plate, mainly because they have hard particles, and soft matrix, generally in the wear process, there will be some shedding substances, these substances will be integrated into the soft matrix that will not cause great harm to the surface; if the matrix hardness is relatively high, shedding of abrasive or other substances, the mutual movement will be mutual lapping, faster damage matrix!
Q:Are there any restrictions on the thickness of the steel plate, such as the minimum thickness of the steel plate?
If the intensity is enough, you should be the first 4mm for the economy. Carbon steel plate, with electrode arc welding, 2 diameter welding electrode on line.If it is stainless steel, tungsten argon arc welding is better
Q:What are the problems encountered in the construction of steel sheet piles? How to deal with
Based on the soft, sometimes the construction was adopted into the adjacent pile phenomenon, measures is the number of adjacent piles are welded together, and in the application of play pile connected locking coated with butter and other lubricants to reduce resistance
