What is the S690QL equivalent ASTM application

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 S690QL equivalent ASTM 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 S690QL equivalent ASTM to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

Q420 steel is a kind of low alloy high strength structural steel. The tensile strength of Q420 steel is 420 MPa. S690QL equivalent ASTM, Q420 steel is very suitable to make steel plate, and the strength is much higher than Q235 steel. S690QL equivalent ASTM, Q420 steel has high strength, good fatigue resistance, high toughness and low brittle transition temperature, good cold forming performance and welding performance, good corrosion resistance and certain wear resistance. Q420 steel is suitable for power tower, all kinds of crane, heavy truck, oil derrick, high temperature fan, large electric shovel, dump truck and drilling rig, coal mine hydraulic support, steel structure, etc. application.

304 stainless steel plate products have strong corrosion resistance. For ordinary alkali solution and organic acid, inorganic acid has good corrosion resistance. This material S690QL equivalent ASTM is a high alloy steel, which can resist corrosion in air or chemical corrosive medium.

With the increase of temperature, the yield limit of S690QL equivalent ASTM will decrease monotonically, but the tensile strength of S690QL equivalent ASTM will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of S690QL equivalent ASTM. Near the blue brittleness temperature, the S690QL equivalent ASTM strength increases and the plasticity decreases. The elongation and section shrinkage of S690QL equivalent ASTM 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.
