Ready stock high strength steel plate S690QL price

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 high strength steel plate S690QL 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 high strength steel plate S690QL to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

A633GrD steel plate is suitable for normalized high-strength low-alloy structural steel plate for tower connection or source bolt connection structure. A633GrD steel plate should be normalized: heat the steel plate to a suitable temperature that can produce austenite structure but does not exceed 1700F [925℃], and keep it at this temperature for a period of time, so that the entire high strength steel plate S690QL plate can be uniformly heated, and then left in the air Cool with medium.

Corrosion resistant steel is a kind of stainless steel, which can resist corrosion in some strong corrosive media. Stainless steel can only resist corrosion in air or weak medium. Stainless steel is not necessarily corrosion resistant, corrosion-resistant steel must be stainless steel. Corrosion resistant steel is durable and can be stored outdoors for a long time without being damaged in bad weather. Corrosion resistant steel is not easy to rust, but it is not absolutely rust free. The strength, precision and toughness of high strength steel plate S690QL, corrosion resistant steel are very good, and can be the processed and used for many purposes.

Laser cutting high strength steel plate S690QL has no burr, wrinkle and precision is high. It is superior to plasma cutting. Laser cutting has good cutting quality, narrow cutting width (generally 0.1-0.5m m), high accuracy (generally 0.1-0.4mm hole center distance error, 0.1-0.5mm contour dimension error), good surface roughness (generally Ra is 12.5-25μm), and the high strength steel plate S690QL cutting seam can be welded without further processing. Fast cutting speed: for example, with 2kW laser power, the cutting speed of 8mm thick carbon steel is 1.6m/min.

high strength steel plate S690QL, S355JR is a European standard low alloy high strength structural steel, which is in accordance with EN10025-2. The hardness of S355JR steel is 70-80B, and the yield strength of S355JR steel is 355MPa. JR stands for quality level, equivalent to level B in ChinaChemical composition of S355JR steel: C: < 0.22; Si: < 0.55; Mn: < 1.60; P: < 0.025; S: < 0.025S355JR steel is equivalent to Q345B in China.
