What Are The Mild Steel Plate standard of nm450 wear-resistance Properties

As people have higher and higher requirements for the quality of various steel processing products, the market demand for standard of NM450 wear-resistance, pickling steel coils is getting better and better. At present, they are mainly concentrated in the automotive industry, compressor industry, machinery manufacturing industry, spare parts processing industry, fan Industry, motorcycle industry, steel furniture, hardware accessories, electric cabinet shelves and various shapes of stamping parts. With the advancement of technology, hot-rolled pickled steel plates are currently involved in home appliances, containers, electrical control cabinets and other industries.

Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and standard of NM450 wear-resistance heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported standard of NM450 wear-resistance to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

TMCP process is an important means to improve the comprehensive properties of steel. It can be used to produce ship plate, vessel plate, boiler plate, bridge steel, etc. Compared with the normalized steel of the same strength grade, TMCP can reduce the alloy content of the standard of NM450 wear-resistance steel, reduce the carbon equivalent and improve the welding performance. TMCP is more and more widely used in various types of steel rolling industry.

With the increase of temperature, the yield limit of standard of NM450 wear-resistance will decrease monotonically, but the tensile strength of standard of NM450 wear-resistance will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of standard of NM450 wear-resistance. Near the blue brittleness temperature, the standard of NM450 wear-resistance strength increases and the plasticity decreases. The elongation and section shrinkage of standard of NM450 wear-resistance increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.

The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
