What is special-shaped S690QL pipe

The company adheres to the S690QL pipe external market, internal management, quality and efficiency oriented development path, and has achieved good economic and social benefits. With strong financial strength, advanced management experience, excellent sales service, strict quality management system and scientific overall marketing means, we will work hand in hand with you for common development. We are making all efforts working on the optimization of S690QL pipe quality and price and best service for all our customers.

ASTM a992 steel S690QL pipe is recognized as the most suitable steel for wide flange beam in the world. It contains a variety of alloy elements, such as vanadium, niobium, copper, nickel, chromium and molybdenum, which greatly improve S690QL pipe its strength and other properties. For example, the mechanical properties are much better than the tensile strength 65ksi and yield strength 65ksi of a572-50 and A36. Therefore, a992 wide flange beam (H beam) generally replaces a572-50.

The excellent properties of wear resistant steel plate meet the strict requirements of high strength, high wear resistance, stability, straightness and surface quality. The combination of high hardness, high strength and excellent impact toughness makes S690QL pipe plate become an ideal material for a wide range of applications. The production thickness of wear resistant steel plate is generally between 8-100mm.

Generally speaking, the higher the strength of S690QL pipe, weathering steel, the greater the hardness, while the plasticity and toughness will decrease. When the carbon content of weathering steel exceeds 1.2%, the hardness will increase, but the strength will not increase, but will decrease. Resilience will also decline quickly. When the carbon content is high, the cementite increases and forms network distribution, which weakens the connection between grains and makes the mechanical properties of steel worse.

GB standard wear resistant steel plates parameters: The standard for Chinese wear plates is GB/T 24186, which includes NM400, NM450, NM500, NM550, NM600 etc. steel grades. According to the standard, the NM400 plate thickness is no more than 80mm, and hardness is 370-430HBW. S690QL pipe, NM450 plate thickness is no more than 80mm, and hardness is 420-480HBW. NM500 plate thickness is no more than 70mm, and hardness is 470HBW min. And NM600 plate thickness is no more than 60mm, and hardness is 570HBW min.
