Galvanized Corrugated Steel Plate Description What is Corrugated Steel Plate and what is it used for? Corrugated sheet metal is produced by stretching a sheet of metal and then rolling it through a rolling die to create a linear, wavy pattern of crests and troughs; they are laid next to each other and are mainly used in outbuildings, barns, industrial warehouses, agricultural applications And waterproof roofs for commercial buildings, where aesthetics are less important, but waterproofing is important. In recent years, corrugated roof panels have been used as cladding in bars and clubs to add an industrial or gritty urban feel. This form of corrugated profile metal sheet or sheet is also commonly referred to in the building industry as roof cladding; they are usually installed with a half-corrugated overlap to make it waterproof, our corrugated steel roofing sheets are galvanized to increase the protection and corrosion resistance. The benefits of using corrugated steel sheets in your projects; - highly robust - light weight - Weather and corrosion resistant - excellent quality of protection - easy to install Complete your corrugated roof sheet. Corrugated steel roof sheets are galvanized to provide a highly corrosion- resistant surface, so no further painting or other surface treatments are required to improve the for extra protection. However, for aesthetic purposes, galvanized products can be painted or powder coated if desired. Order corrugated steel roofing sheets from Hebei Shineyond. Introduction Galvanized Corrugated Steel Plate is pressed from galvanized or galvalume coils and can be produced in different tile shapes as required. Usage Gi sheet is widely used in roof panels, wall panels, floor panels and ceiling panels.

Checkered Steel Plate Description Checkered Steel Plate is a steel plate with a raised (or recessed) pattern on the surface. The pattern is lentil-shaped, diamond-shaped, round bean-shaped, and mixed flat and round shapes. The lentil shape is the most common in the market. The pattern can be a single diamond, lentil or round bean shape, or a combination of two or more patterns to become a combined pattern plate. Due to the diamond pattern, the risk of slipping is greatly reduced. Checkered Steel Plate is commonly used in structures such as stairs, ramps, walkways and vehicle interiors. It can also be found in construction applications. Checkered Steel Plate Precautions 1. After the materials are transported to the site, they should be stacked according to the specifications and installation positions, and the square wood should be padded to prevent the rain from scouring. The stacking height should not be too high to prevent deformation caused by being overweight. 2. In order to meet the requirements of the overall construction progress, the laying of the patterned steel plate is closely connected with the installation of the steel structure. After a certain stage of anti-corrosion work on the steel beam, the patterned steel plate can be laid. The laying sequence is the same as the steel beam installation sequence. 3. On the patterned steel plate, the lifting lugs are welded on the ground, and the holes to be welded on the secondary beam and the frame beam are cut with flame. The size of the opening is 6mmx12mm, and the spacing is not more than 0.5m.

4340 steel is nickel-chromium-molybdenum alloy steel. It will get high strength after the heat treat. And it has good toughness, fatigue resistance, impact toughness and etc. Its equivalent grade is JIS SNCM439 and DIN 1.6563. The properties and composition of 4340 steel round bar sheet plate as below. It is an alloy structural grade which used by the SAE International(SAE), and it is chrome-nickel low alloy steel. 4340 steel round bar sheet plate will get high tensile strength, hardness and toughness after heat treatment. It is used widely in the transmission components of heavy chemical machinery. Different sections of each part of the casting which cause the temperature difference stress and phase transformation stress. If you can’t get their laws and characteristics, you can’t take the right rational processes. The consequence is that there is a risk of cracking the casting during the casting or heat treatment. So the control of chemical composition and the choice of the heat treatment process for the casting are really important. Describe: 4340 belongs to the American standard high-strength alloy structural steel, which is made of high-quality carbon structural steel by appropriately adding one or more alloying elements (the total content does not exceed 5%). Corresponding steel number: China GB steel number 40CrNiMoA, German DIN steel number 36CrNiMo4, German DIN material number 1.6511, French NF standard 40NCD3, Japanese JIS standard SNCM439, British BS standard 816M40, American AISI/ASTM4340, American UNS standard G43400 What we do?

AISI 4140 Steel Characteristics 1.It is low alloy steel with chromium, molybdenum, and manganese. 2.Great toughness, fatigue strength, abrasion and impact resistance. 3.It is widely be used in the industry due to its excellent versatility and usefulness. 4.The higher carbon content in it, the higher the strength and heat treatment capabilities it is. 5.It can be oil hardened to relatively high hardenability. ASTM 4140 Steel Application 4140 steel is medium hardenability steel with good strength and good comprehensive mechanical properties after heat treatment. It has good manufacturability. The maximum temperature of use is 427 °C. It can be used to make turbine fastener, tool bodies, forming dies, brake dies and etc. And it also as the material of Oil deep well drill pipe joints and fishing tools below 2000m. 4140 Steel Round Bar Sheet Plate Heat Treatment Machinability At the annealed condition, 1.7225 alloy tool steel has good machinability. Forming DIN 1.7225 steel has high ductility. It can be formed using conventional techniques in the annealed condition. It is required more pressure or force for forming because it is tougher than plain carbon steels. Welding 1.7225 alloy steel can be welded using all advanced techniques. But, the mechanical properties of it will be affected if it is welded in the heat treated condition, and post weld heat treatment should be performed. Heat Treatment 1.7225 tool steel is heated at 845°C(1550°F) followed by quenching in oil. Before hardening, it can be normalized by heating at 913°C (1675°F) for a long period of time followed by air cooling. Forging It is forged at 926 to 1205°C(1700 to 2200°F) Hot Working 4140 steel can be hot worked at 816 to 1038°C(1500 to 1900°F) Cold Working 1.7225 steel can be cold worked using conventional methods in the annealed condition. Annealing Heat it to 800℃ – 850℃, hold until temperature is uniform throughout the section and cool in furnace. Normalizing Heat 1.7225 alloy steel to 870℃ – 900℃, hold it until the temperature is uniform throughout the section, soak for 10 – 15 minutes and cool in still air. Tempering DIN 1.7225 steel can be tempered at 205 to 649°C (400 to 1200°F) depending upon the desired hardness level. The hardness of the steel can be increased if it has lower tempering temperature. For example, tensile strength of 225 ksi cab be achieved by tempering at 316°C (600°F), and tensile strength of 130 ksi can be achieved by tempering at 538°C (1000°F). Hardening DIN 1.7225 alloy steel can be hardened by cold working, or heating and quenching. Test How is SAE 4140 steel tested? Our AISI 4140 steel round bar and steel plate composition detection is carried out by a spectrometer, which is fast, accurate and efficient in detection; hardness is tested by a hardness tester, The hardness tester is based on the Leeb hardness measurement principle, which can easily and quickly measure a variety of metal materials. While displaying the hardness measurement value immediately, it can be freely converted between different hardness scales, and the tolerance limit can be set in advance, and it will automatically alarm when it exceeds the range. 1. Measuring range: (170-960)HLD,(17-68.5)HRC,(19-651)HB,(80-976)HV,(3 , 0-100)HS, (59-85)HRA(13-100 )HRB 2. Measurement direction: support 360° (vertical down, oblique down, horizontal, oblique up, vertical up) 3. Hardness scale: Richter (HL), Brinell (HB), Rockwell B (HRB), Rockwell C (HRC), Rockwell A (HRA), Vickers (HV), Shore (HS) 4. Display: quarter dot matrix LCD 5.
