silicio organico 300mg e pqq 10mg

Deoxygenation of boiling steel is incomplete, oxygen content is high, phosphorus and other impurities distribution is uneven, local overspending, aging sensitivity and cold brittle sensitivity are high, hot cracking tendency is added. If unqualified electrode is used, if the content of carbon and sulfur in the weld metal is too high, cracks will occur. For example, when factories use acidic electrodes to weld Q235-A steel, the high carbon fernoganese in the electrode coating will lead to thermal cracks in the weld.

As we all know, the use of hexagonal net for protection can protect the natural environment while protecting the bridge, which can not only green the ecological environment, but also prevent soil erosion.

Spring steel wire should have high tensile strength, elastic limit, endurance and fatigue strength, and resistance to impact and oscillation. The strength and endurance objectives, especially to prevent the occurrence of modification cracks, are the key to the consumption of spring wire. The inner quality and outer quality of the wire rod directly affect the function of the wire.

Hook net raw materials are basically low carbon steel wire, stainless steel wire and aluminum alloy silk woven, and what are the characteristics and use of these raw materials? Low carbon steel wire is actually the wire we usually use, plasticity is good, good patience, pull is very good.

Large hexagonal mesh called stone cage net, is mainly used for mountain protection, hydraulic construction and so on. Small wire hexagonal mesh is used as a good material for breeding, will twist twist hexagonal mesh in the welded iron frame on the hexagonal mesh welding into chicken coop, pigeon cage, rabbit cage cage cage, hexagonal mesh is the best material for breeding with a net.

Generally, galvanized wire used for welding is required to have a certain hardness. After acceptance of galvanized wire, the first thing to do is to feel the hand, and the other thing is to test on the machine. Because the average user does not have testing equipment, it is also very inconvenient to test on the machine. Use a micrometer to measure the diameter of galvanized wire evenly, and keep it about 0.02mm above and below the contract signing standard, with neat appearance, no leakage plating and no mess.

Immersed six edge barbed wire corrosion lost the original characteristics, in the shape, color and mechanical properties and other aspects will change, resulting in equipment damage, pipeline leakage, specifically, is prone to fracture, lose the original protection function. Corrosion usually metal corrosion has three types: physical, chemical corrosion and electrochemical corrosion, and corrosion depends on the chemistry of the metal itself and the organizational structure, still have relationship with the surrounding medium, such as wet environment than dry environment is easy to rust, more less than the impurities of impurities is easy corrosion, high temperature conditions than under the condition of low temperature corrosion, etc. After understanding these, we can effectively prevent the corrosion of the six sides of the wire, prolong the service life of the product.

Any application environment, users want a better the strength of the welded wire mesh, only need to improve its intensity, will make better the habit of using demand, but to be improved in the strength of this product, also need yo have a variety of conditions, will need to see factory in produce what kind of material, the strength of the product also is the material strength, But a manufacturer in the data does not fit the strength requirements, after all, there is no way to make the strength of the product progress, so this is the condition to.

Hexagonal mesh is also known as twisting mesh, thermal insulation net, soft edge net. It is made of single – layer mesh. Its mesh, mesh wire, galvanized and PVC film properties and the same as the cage. This product can be different shapes and sizes of the block stone into the alloy net to form a flexible whole, through lifting, car, shipping to the place, the alloy net connected to each other into a larger whole, construction throwing convenient, fast, good economic performance.

Second, composition. Model 201 is composed of 17Cr-4.5Ni-6Mn-N, which is a substitute steel for type 301 steel. Anping wire rolling cage is magnetic after cold working, used in railway cars. 304 composition of 18Cr-9Ni, is the most widely used stainless steel, heat resistant steel. Used for food production equipment, Xitong chemical equipment, nuclear energy, etc.

Choose a well-structured crate, such as one with a tray under it so the dog can pee and defecate in it. It’s also easy for the host to clean up.
