What is the hardness of the wear-resistant steel plate?
- WZB-NM500 is the production of Wugang is more than 450 hardness of HB class can be used welding of high strength wear-resistant steel structure, the manufacturing equipment is suitable for use in high wear, high impact situations, but also can be used as high strength structural steel yield strength more than 700MPa. His hardness can reach about HV1300.s
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).s
Q235 is hot rolled steel or cold rolled steel?
- Hot rolling and cold rolling are forming processes of profiled steel or sheet steel. They have a great influence on the microstructure and properties of steels. Steel is rolled mainly by hot rolling, and cold rolled only for the manufacture of small sections of steel and thin plates.The advantage of hot rolling is that it can destroy the casting structure of steel ingot, refine the grain of steel, and eliminate the defects of microstructure, so that the steel structure is compact and the mechanical properties are improved. This improvement is mainly reflected along the rolling direction, so that steel is no longer a certain extent, isotropic body; casting formed when bubbles, cracks and loose, can also be welded under high temperature and pressure.s
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.s
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.s
What type of welding rod is used for steel Q245R and Q235B material?
- If the welding weld is non pressure parts, you can use the CO2 gas shielded arc welding, using 1.2 or 1.6 ER50-6 diameter wire welding, weld spatter if you need better or less, recommend the use of Ar:CO2 mixed gas 8:2 welding.s
How is the weight of the steel plate calculated?
- Steel plate by thickness, thin steel plate <4 mm (thinnest 0.2 mm), thick steel plate 4~60 mm, extra thick steel plate 60~115 mm.The steel plate is divided into hot-rolled and cold-rolled parts according to rolling.The width of the sheet is 500~1500 mm; the thickness is 600~3000 mm. According to the type of steel sheet, ordinary steel, stainless steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel and industrial pure iron sheet; according to professional use, with drums board, enamel board, bulletproof plate; surface coating and plating, plating with zinc thin plate, tin plate, plating lead sheet, plastic composite plate.s
What's the difference between a spray plate and a colored steel plate?
- Plastic sheet, first can choose the thickness and material on the plate, and then spray processing, and then processing the plastic powder color and quality can choose according to your requirements, general plastic plate from high-end to low-end can meet your requirements, if you need to own production will be cumbersome!s
