Galvanized Wire: Galvanized wire refers to a type of wire that has been coated with a layer of zinc to enhance its corrosion resistance. The process of galvanization involves immersing the wire in a bath of molten zinc or applying a zinc coating through electroplating. Galvanized wire is commonly made from carbon steel wire and is used in a wide range of applications, including fencing, construction, agriculture, and crafts. The zinc coating provides protection against rust and extends the lifespan of the wire.

All countries in the world have chosen the trend of using high-carbon chromium bearing steel as the bearing steel; in order to improve the hardenability, the demand for custom-made thick-walled parts is the first to be carried out in the following aspects: /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
Highly hardenable steel in order to get used to the requirements of large-scale bearing parts; copy developed high hardenability steels GCrl5SiMo, GCrl8Mo.
Appeared hardened steel GCr4
Used for railway and rolling mill bearings; using the lower hardenability of the steel; water cooling after medium frequency induction heating; obtaining a hardened layer of a certain depth on the outer part of the part; function and carburizing steel near the carburizing quenching arrangement; High heart tolerance, etc.
Martensitic stainless steel custom high carbon martensite stainless bearing steel 9Crl8, 9CrlSMo (440C) has high carbon and chromium content; coarse eutectic carbides occur during condensation; and can not be modified by future heat treatment. Coarse carbonization The material tends to constitute high stress and attracts data loss; reducing the chromium content of the martensite matrix will result in lower hardness and lower corrosion resistance after heat treatment. Others; the presence of coarse eutectic carbides. Roughness; increase the noise of the bearing. Therefore, the presence of eutectic carbide should be minimized in the steel.
In recent years, we have developed 0.7C-13Cr martensitic stainless steel; after reducing the carbon and chromium content; reducing the eutectic carbide content and scale. The steel has the touch fatigue function, hardness, impact resistance and corrosion resistance in salt water. At 440C; however, the corrosion resistance in sulfuric acid and hydrochloric acid solution is not as good as 440C. The steel is mainly used for rust and corrosion resistant fine bearings and shaft bearings; such as low noise video recorder drum bearing components, computer hard drive bearings and Dental drill bearings, etc.
High-nitrogen steel HNS developed in Germany; the first is to reduce the carbon content in 440C and add nitrogen content; to improve corrosion resistance and durability; and do not add too much production cost. The steel's resistance, corrosion resistance and fatigue The function is better than 0.7C-13Cr and 440C. The bearing made of this steel has higher life in water than the bearing made of conventional bearing steel.
GT steel, which improves alloy composition and improves matrix strength, developed GT steel in Japan; improved matrix strength and durability; improved tempering stability together. Used in heavy duty, clean and smooth conditions or small and lightweight conditions. Bearing.
The TF series of pollution-resistant steel is used in bearings with smooth pollution; the hard contaminant particles in the smoothing agent (such as foreign dust, wear debris of other parts, etc.) enter the touch area; the surface of the touch part constitutes an indentation The stress constituting the edge of the indentation gathers; constitutes the source of exhaustion of the external surface; constitutes the early failure of the bearing part. The influence of the pollution particle on the lifespan depends on the hardness, quantity and scale of the pollutant; the higher the hardness, the larger the quantity, the more the scale Large; the greater the impact on the bearing life. In this case; the choice of the above method has no significant effect on the life and reliability of the progressive bearing; useful method is to hinder the formation or reduction of the indentation The stress at the edge of the indentation gathers.
TP series carburizing steel can be divided into TF, HTF, STF and NTF; it can greatly improve the life of the bearing under the condition of smooth pollution. TP steel properly improves the C content of the matrix; the bearing made of this steel is smooth in pollution The lifespan under the condition is 4 times higher than that of the bearing made of ordinary bearing steel. HTF steel selects higher Cr and Mn content on the basis of TF steel; promotes the formation of many fine carbides in the matrix and obtains more in the layer. A large amount of retained austenite; bearings made of this steel have a lifespan of more than six times better than those made with ordinary bearing steel, and STF steel participates in 1% of Mo on the basis of HTF; Get more and finer carbides or carbonitrides; the number of carbides is three times that of TF steels; bearings made from this steel have a longer life under contaminated conditions than bearings made with ordinary bearing steel. Nearly 10 times, NTF steel is similar to HTF steel; only precious elements have less Cr and Mn content; bearings made with NTF are lower in price than ordinary bearing steel bearings. Others; TP series steel bearings have excellent wear resistance And bite limit; scale stability between full hardening and pass Often external hardened data.
Quasi-high temperature steel NTJ2, KUJ7
When the GCrl5 steel bearing is used in the quasi-high temperature zone of 100 °C ~ 200 °C; under the effect of the high temperature text touch force; the subsurface layer constitutes the low hardness ferrite white bright zone; the Bailiang zone becomes the later exhaustion source; the rolling bearing life is reduced Together; the hardness of the bearing is reduced; the wear resistance and scale accuracy are deteriorated; the cooperation gap is changed; even the bearing is stuck. If the M50 type high temperature data is used; the bearing cost must be added. The bearing life under the high temperature operation condition is improved. The useful and sellable method is based on the composition of GCrl5; properly improve the content of Cr, Si, Mo, etc. to hinder the composition of the white bright zone to improve the high temperature function. Quasi-high temperature bearing steel NTJ2, KUJ7; at 150 ° C - 180 °C operating temperature; life, scale stability, etc. are better than 200 °C high temperature tempering treatment GCrl5. This kind of quasi-high temperature steel is uniquely suitable for the production of automotive engine spindles, generators, copiers and thermal processing machinery bearings.
High temperature bearing steel The traditional high temperature bearing steel is T1 (W18Cr4V), T2, T10, M50 (Cr4M04V), etc.; these fully hardened steels can satisfy many application requirements; such as high high temperature hardness, etc. Many valuable elements such as Cr, Mo, W, V; use secondary hardening to improve many operating temperatures; but high prices, coarse carbides. To refine the coarse carbides that have a helium effect on the life of rolling bearings; Exercise; and lack of tolerance; under high speed, high stress; its reliability is difficult to ensure.
High-temperature carburizing steels such as RBD, CBSl000, and M50NiL are announced in Europe and the United States; M50NiL is the most widely used; after carburizing; fine carbides in the infiltrated layer. 阄 阄 嘌褂 Γæ牟 Γæ牟 Γæ牟 M M M50 of 2.5 Double; after hard chrome plating; its fatigue life is 6 times M50. Currently; the steel is mainly used in aerospace engine spindle bearings and other bearings requiring high temperature, high speed, high stress, high reliability and shape.
