mechanical properties of nm550 manufacturer in China

Available steel plates: carbon structural steel, low-alloy high-strength steel, steel plates for bridges, steel for building structures, steel angles for shipbuilding and offshore platforms, steel sheets for boilers and pressure vessels, mechanical properties of NM550 steel plates for molds, steel plates and strips for alloy structures, corrosion-resistant steel, wear-resistant steel, pipeline steel for oil and gas transportation.There are more than 300 domestic and foreign steel grades in our supply list.

Wear resistant plate is composed of two parts, namely carbon steel plate and alloy wear-resistant layer. Under normal conditions, the thickness of the mechanical properties of NM550 alloy wear-resistant layer of the wear-resistant plate is 1 / 3-1 / 2 of the total thickness. When working, the matrix provides the strength, toughness, plasticity and other comprehensive properties to resist external forces, and the alloy wear-resistant layer provides the mechanical properties of NM550 wear-resistant property to meet the requirements of specific working conditions.

Hydrogen (H) is the most harmful element in general steel such as mechanical properties of NM550. Hydrogen dissolved in steel will cause hydrogen embrittlement, white spots and other defects. Hydrogen, like oxygen and nitrogen, has very little solubility in solid steel. It dissolves into liquid steel at high temperature, and accumulates in the structure without time to escape when cooling, forming high-pressure micro pores, which greatly reduce the plasticity, toughness and fatigue strength of steel, and even cause cracks and brittle fracture in severe cases. "Hydrogen embrittlement" mainly occurs in martensitic steel, but not very prominent in ferrite steel, and generally increases with hardness and carbon content.

The black futures market is weakening. Terminal and middlemen are cautious in their inquiry and purchase, and mechanical properties of NM550 merchants have different shipments. However, the factory price of mechanical properties of NM550 keeps rising and the spot bottom is more supportive. The market mentality is still good. The high demand is limited, but the support from the raw material side is strong. It is expected that the mechanical properties of NM550 price will be stable tomorrow.
