What is the 20MnB5 steel material for turbine part element chemical composition
Our company was founded in 2000, which initially committed to providing high-quality steel 20MnB5 steel material for turbine part products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export 20MnB5 steel material for turbine part steel to the international market, opening up the international steel market.
The output of stainless steel affects the price: when the market output of 20MnB5 steel material for turbine part, stainless steel is lower than the market demand, the price will rise. This is related to the operating rate of global stainless steel mills and the price trend of stainless steel raw materials. As a stainless steel buyer, it is necessary to control the purchasing stock reasonably, find a suitable and stable supplier, and understand the company's demand for future production.
Bridge steel plates are thick steel plates made of carbon steel and low-alloy steel for bridge construction. The main applications of bridge steel plates are to build railway bridges, highway bridges, and sea-crossing bridges. The bridge steel plates are required to have high strength, durability and bear the load and impact of rolling stock. Bridge steel plates have good water resistance, low thermal conductivity, flat and lubricated surface. The main grades of bridge steel plates are A709 grade 50, A588 grade B, 20MnB5 steel material for turbine part and so on.
In the past, 20MnB5 steel material for turbine part, NM360 wear-resistant steel plates generally do not add tungsten. However, after adding the alloying element tungsten, the carbides distributed along the grain boundaries are greatly reduced, the acicular carbides in the crystal disappear, and there are a large number of granular carbides in the crystal. Tungsten reduces the precipitation of carbides and is spherically dispersed in the austenite crystals, which is beneficial to improve the strength and toughness of the NM360 wear-resistant steel plate.
