Q:What does steel plate "A3" mean?
Using Q235 steel as punch material, after quenching without tempering, direct use, hardness of 36~40HRC, solved the punch in use in the phenomenon of fragmentation
Q:How much is 2 millimeters per square meter?
GB two mm steel plate per square weight of about 15.7 kilograms, converted into per square should be 80-100 yuan.Steel plate is made of molten steel, cooled and compressed into flat steel. 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 by rolling
Q:What material can be replaced by 345D steel plate?
Higher than its level of material of steel plate can replace.Q345D. yield in more than 345 of the steel.D class -20 degree of shock. Can replace the Q370D.Q390D.Q420D.Q460D.Q550D.Q690D., generally in engineering machinery can be higher generation low
Q:What is the width of carbon steel coil and the width of stainless steel coil, one is 1250 and the other is 1219?
Domestic stainless steel rolling mill is generally 1219, but the design standard is 1300, so there will be flash board 1250, that is not the standard board, belonging to the flash, waste materials, many products manufacturers are also in 1219 as a reference size, product development, if the plate width will be wasted, a lot of scrap production the process, so the business order is generally around 1219 stainless steel coil.
Q:What does "steel plate 10t" mean in the specification column of engineering material?
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.
Q:How can the steel plate of flat welding 10mm make its deformation smaller?
The most simple way is to set up a few blocks in the weld transverse positioning plate, welding seam after cooling in the two side gently hammering stress relief force dismantled.
Q:What is the difference between cold rolling and hot rolling?
With the continuous casting slab or as raw material, after reheating furnace heating, descaling into the roughing mill of high pressure water, roughing material by cutting head, tail, and then enter the finishing mill, the implementation of computer controlled rolling, after finishing through the laminar cooling (computer controlled cooling rate) and coiler and become straight hair volume. Hair straightenerrollhead, tail tongue shapeand thefishtail shape, thickness, width of poor accuracy, edgehaswavy, folding, tower and other defects. The coil weight is heavy, and the inner diameter of the steel coil is 760mm. (general management industry likes to use. Thestraightthroughcutting) cutting head, tail cutting, trimming and multipass straightening and leveling finishing line processing, cutting board or heavy volume, which becomes: hot rolled steel plate and flat steel coils, slittingstripand other products. Hot finishing rolling by pickling descaling and oil is made by pickling hot-rolled coils.
Q:How much is the rent for a day of Larson steel sheet pile
400mm broad Larsen steel sheet pile rental price:9m, 12m:0.60 yuan, /m/ days15m: 0.70 yuan /m/ days18m: 0.80 yuan /m/ days
Q:What material can be used for A36 steel plate?
The A36 plate is used instead of the standard Q345 American Standard.
Q:What does "Z" mean to the performance of steel?
The Z plate is used to prevent lamellar tearing of plates, the main connections at the plate, if the plates in the thickness direction bear significant tensile stress on the sheet.
