What is the chemical composition of nm550 steel chemical composition?

Our company was founded in 2000, which initially committed to providing high-quality steel NM550 steel chemical composition 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 NM550 steel chemical composition steel to the international market, opening up the international steel market.

The company produces and export steel plates and steel section products of various materials all year round. The width of the NM550 steel chemical composition thin plate is 500 - 1500 mm; the width of the thick plate is 600 - 3000 mm. Steel plates are classified by steel type, including ordinary steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, etc .; according to use, there are shipbuilding plate, pressure vessel plate, wear resistant steel plate, bridge builidng steel, corten steel plate, and pipeline steel plate.

42CrMo steel plate is an ultra-high strength steel plate, which is widely used in machinery manufacturing steel. The steel is suitable for manufacturing large and medium-sized plastic molds that require certain strength and toughness. 42CrMo steel has high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after quenching and tempering, and good low temperature impact toughness.

In the past, NM550 steel chemical composition, 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.

The proportion of main elements in Q345 steel is basically the same as that in 16Mn steel, the difference is that V, Ti, Nb microalloy elements are added. A small amount of V, Ti, Nb alloy elements can refine the grains, greatly improve the toughness of the steel, and greatly improve the comprehensive mechanical properties of the steel. Because of this, the thickness of NM550 steel chemical composition, Q345 steel plate can be made larger. Therefore, the comprehensive mechanical properties of Q345 steel should be better than that of 16Mn steel, especially its low temperature properties. The allowable stress of Q345 steel is slightly higher than that of 16Mn steel.

We have our own factory, including the production and manufacturing of steel pipes, with a special NM550 steel chemical composition steel pipe manufacturer and storage warehouse. Welcome to visit our factory, we will provide customers with high quality products that meet the requirements. And has the perfect NM550 steel chemical composition after-sale service guarantee system, lets the customer save the worry and the labor.

Both parties shall confirm the NM550 steel chemical composition material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the NM550 steel chemical composition steel plant.
