C - section steel is reliable and stable in stress can be accurately positioned, and is resistant to impact and vibration Moreover, it has good versatility and combination, and has a variety of C-section steel and size selection to ensure its flexibilityThe wear resistance, fracture toughness, impact toughness and bending strength under different process conditions were compared, and then the heat treatment process of GCrMo was determined. Development and application of ZYS- bearing damping and antirust oil. Bearing is a new type of multial damping and antirust oil. It takes refined mineral oil as the base oil and is equipped with various additives such as antirust and antifriction. Through comparison test, matching test with lubricating grease and user test, it is proved that ZYS- bearing damping and antirust oil has outstanding damping effect and good antirust lubrication performance.BOGO Wenjie,According to the data information display information, there is an inseparable correlation between the annual real estate sales data information and the apparent consumption data information of galvanized pipe. From the consumption surface of the middle and lower reaches of galvanized pipe, decoration design, elevator car, handicrafts, household appliances and other industries are closely related to the situation of the real estate industry.So why is the alloy pipe easy to rust after being pickled and passivated by the software?Milbur Haas,I-beam is mainly divided into ordinary I-beam, light I-beam and wide flange I-beam. According to the height ratio of flange to web,BOGO Wenjie1Cr5Mo alloy pipe, medium and narrow flange I-beams. The specifications of the first two are -, the light I-beam has narrow flange, thin web and light weight. Wide flange I-beam, also known as H-beam, is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill, so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.Performance parameters and application scope of I-beamThe general alloy pipe with improved performance is variable and has high application value. The alloy pipe contains more Cr and is heat resistant Low temperature resistance Corrosion resistance. There is no aluminum alloy in plain carbon seamless steel pipe, not very little aluminum alloy, and the alloy pipe is used in crude oil Aerospace Chemical plant Power engineering heating furnace. Because the physical properties of alloy tubes are easy to change and adjust.

I-beam can only be used for beam, while H-beam can be used for load-bearing column of structure.Galvanized pipe can be seen from its name. It is a square pipe type. Many materials can form galvanized pipe body. It is used for what purpose and where. Most galvanized pipes are steel pipes. After unpacking,BOGO WenjieHow many 20 rebar in a bundle, leveling, crimping and welding, they form round pipes, which are rolled into square pipes, and then cut into the required length. Generally, there are galvanized pipes in each package. In terms of spot,BOGO WenjiePrice of 42CrMo alloy pipe, most of them are in large specifications, ranging from * * .- to * * - Galvanized pipes are divided into structural galvanized pipes, decorative galvanized pipes, architectural galvanized pipes, mechanical galvanized pipes etc.Key technical characteristics of alloy pipe:Test conclusion,Alloy pipe is a very important way and type of seamless steel pipe. Its use is relatively common. It is widely used in various engineering projects, house construction and building decoration. Its fracture will always be found in the production, manufacturing and key marketing of alloy pipe, That is, many stages of production and processing are not done well. Another is that the seasoning is not enough and the proportion of chemical molecules is wrong. There are all reasons.Patented manufacturing process of I-beam: I-beam has become a new industrial standard for wear-resistant materials Remove defective pipes within the allowable length.

The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.Production department,Whether I-section steel is ordinary or light, because the section size is relatively high and narrow, the moment of inertia of the two main axes of the section is quite different, so it can only be directly used for members bent in the plane of their web or form lattice stressed members. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which makes it very limited in the scope of application. I-beam is widely used in buildings or other metal structures.However, compared with plastics, these pipes, remain stable and will not be affected by high temperature.→ compared with general section steel, it has the advantages of low cost, high precision and small residual stress. It does not need expensive welding materials and weld detection and saves about % of the manufacturing cost of steel structure.BOGO Wenjie,The finished product has smooth surface, low friction coefficient, flatness error + / - mm / m length, wear resistance and maximum temperature of ℃→ compared with the concrete structure, the I-steel structure can increase the service area by %, reduce the self weight of the structure by % - % and reduce the structural design internal force.What is nitriding of alloy pipe
