4x8 A514 grade E steel material metal structural fo sale

The company specializes in the research and development, production and sales of A514 grade E steel material seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has A514 grade E steel material five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,A514 grade E steel material rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.

The alloying elements of low alloy steel are less than 5%. The low alloy steel is added one or several alloy elements on the basis of carbon steel to improve the performance. Such as manganese, silicon, aluminum, nickel, copper, boron, phosphorus, rare earth, etc. A514 grade E steel material Steel with one or more of these elements will have the advantages of high strength and toughness. Due to the addition of few alloy elements, it is called low alloy high strength steel.

NM400 wear plate is widely used in mining machinery, coal mining machinery, environmental protection machinery, engineering machinery and other product parts. Such as excavator, loader, bulldozer bucket plate, blade, side blade, crusher liner, etc.. NM400 wear plate is also commonly used as high-strength structural steel with yield strength ≥ 800MPa. The main function of NM400 wear plate is to provide protection in places or parts where wear resistance is required, so as to prolong the service life of the equipment.

Tempering the important A514 grade E steel material welding structure often use high temperature tempering to remove residual weld stress. Classification: high temperature tempering above 400 ℃, medium temperature tempering 250 ~ 400 ℃, low temperature tempering 150 ~ 250 ℃, Quenching +Tempering is improve A514 grade E steel material strength, plasticity and toughness.

JIS g3101:2004 ss540 structural steel angle contains 0.30% carbon and 1.60% manganese, which greatly improves the strength of steel. Compared with A514 grade E steel material SS400 and ss490, ss540 has higher strength with yield strength of 400MPa and tensile strength of 540Mpa. High strength makes it popular in applications that require strength but weight is a problem.

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.
