Market price prediction of high strength steel plate S690QL

API 5L is a specification for pipeline steel pipe formulated by the American Petroleum Institute. The main steel grades in API 5L are: A, B, X42, X46, X52, X56, X60, X65, X70, X80, X90, X100, X120, etc. In API standard, pipeline steels are divided into PSL1 and PSL2. In the standard, there are slight differences in chemical composition, high strength steel plate S690QL mechanical properties, inspection items, acceptance standards, delivery status, etc between PSL1 and PSL2 steel. For example, API 5L PSL1 X42 requires an upper carbon limit of 0.26, while API 5L PSL2 X42 requires an upper carbon limit of 0.24.

The company adheres to green development, supported by scientific and technological innovation and technological progress, vigorously advocates the high strength steel plate S690QL production and life style of saving, environmental protection, civilization and low carbon, adheres to the new industrialization road and the sustainable development road. Actively carry out international trade and maintain stable economic and trade relations with more than 80 countries and regions including the United States, Germany, France, the United Kingdom, Japan, South Korea and Australia.

Plasma cutting has a wide range of applications. With different working gas, it can cut various kinds of metals that are difficulty to handle by oxygen cutting. Plasma cutting is fast and efficient when cutting metal with small thickness. The high strength steel plate S690QL cutting speed can reach more than 10m/min. Plasma cutting can get a clean, neat, non stick slag cutting surface, while the deformation and thermal effect of the incision are small, its hardness change is little, and the cutting quality is good.

The acicular ferrite pipeline steel can inhibit the formation of polygonal ferrite, promote the acicular ferrite transformation, and improve the precipitation strengthening effect of carbon and niobium nitride by adding molybdenum to reduce the transformation temperature of polygonal ferrite, so as to improve the strength of steel and reduce the ductile brittle transition temperature. The high strength steel plate S690QL, tempered sorbite pipeline steel adopts the heat treatment process of quenching and tempering. The tempered sorbite structure is formed to meet the comprehensive requirements of thick wall, high strength and sufficient toughness.

Our company will accept the product quality objection registration record, pass it to the high strength steel plate S690QL production unit and relevant departments, and timely coordinate the supervision of product high strength steel plate S690QL quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
